Chapter 1 Introducing the BD600+
BD600+Profanity Delay Chapter 1 Introduction Page 1
Document Version 2.3
The Eventide BD600+ is designed to enable a broadcast licensee to prevent obscene and/or libelous material from
being transmitted over the air. It does this by automatically delaying program material by up to 80 seconds, allowing time for a monitoring operator to decide whether the material being delayed fits into either category.
If objectionable material is heard, electronic circuitry allows all or a portion of the delayed audio to be "dumped"
and the program resumed without interruption. The delay time is increased automatically and gradually after the
"dump" occurs. A remote control option allows an external relay to be attached to prevent uncontrolled sources,
such as telephone callers, from being aired until the delay time is again long enough to provide protection.
The BD600+ has a number of special functions to make it convenient to use: the WAIT AND EXIT function can
be used to synchronize to a network or live signal feed, and the RAMP TO ZERO function can be used to decrease the delay time to zero gradually when it is no longer needed for a safety margin.
This manual discusses the use and operation of the BD600+, the BD600E+ and the BD600W+. All of the functions are presented in detail, which may make the manual seem somewhat forbidding. However, the unit is very
simple to use and the apparent complexity portrayed in this manual is due to our desire to offer complete and accurate information.
The BD600+ is a development of the popular BD600. It is similar in most ways to its predecessor, the main differences being that the BD600+ has considerably better audio quality, and a USB serial port as well as RS232.
BD600+ Features:
• Up to 80 seconds of stereo audio delay
• Allows multiple DUMP operations. The
DUMP function may be configured to delete
a portion of delayed audio between 1 and 10
seconds in length
• REBUILD (catch-up) provides fast recovery
from a DUMP or SNEEZE while a show is in
progress
• RAMP TO ZERO reduces the delay slowly
using the same process as Rebuild
• SNEEZE function replaces microphone mute
switch and allows short interruptions to be
unnoticeable
• WAIT FOR SAFE function allows starting a
show with a safe amount of delay
• WAIT AND EXIT drops from full delay to
zero in real time
• PANIC feature dumps all delayed audio and
plays jingle from plug-in card or mutes output
for fixed time while delay rebuilds
• Micro Precision Delay mode allows a front
panel selectable delay between 10mS and
10.0 seconds in steps of 1uS. This is useful
for HD audio and other applications requiring
precise audio synchronization
• Broadcast delay features can be used for
smooth entry and exit to and from Micro Precision Delay mode
• Large numeric display shows amount of de-
lay
• 24-bit Analog to Digital and Digital to Ana-
log converters
• AES/EBU digital audio input and output
• 44100 or 48000 samples per second internal
sample rate or set externally by AES or
Wordclock inputs
• Front panel configuration and display of au-
dio input and output attenuation
• Remote control inputs to trigger SNEEZE and
DUMP or other functions
• Outputs to signal safe condition and DUMP
button actuation or other statuses
• RS232 remote control
• USB remote control
• Compact Flash™ card for jingle play back
and software maintenance

• An RS232 feed delayed by length of audio delay to drive clock or other devices
• 16 programmable remote isolated inputs on rear panel connector to drive internal functions or act
as source for delayed outputs
• 16 programmable outputs to trigger relays, configurable to indicate different timing conditions
including status of all processes, bypass mode or a delayed version of the inputs
• Station Break and other Insert operations
Additional BD600W+ Features
• Stereo audio output to WheatNet-IP™ network.
• Stereo audio input from WheatNet-IP™ network.
• 16 programmable Logic (control) Inputs from WheatNet-IP™ network to drive internal func-
tions or act as source for delayed outputs.
• 16 programmable Logic (control) Outputs to WheatNet-IP™ network, configurable to indicate
different timing conditions including status of all processes, bypass mode or a delayed version
of the inputs
• Station Break and other Insert operations
Front Panel
See Chapter 2 for in-depth explanation of the following controls, or look up individual terms in the In-
dex.
The front panel buttons have indicator lights which are lit when a function is available, with the exception of BYPASS, which is always available.
A flashing light indicates that the function is active. Pressing a button when it is flashing will cancel
the function.
The CONFIG button and configuration mode are intended to be used by an authorized operator only
and thus their operation is intentionally less obvious. See Chapter 3 for configuration mode information.
Since the BD600+ can serve as a broadcast profanity delay or as a precision fixed delay, many of the
buttons have multiple functions, including navigating the configuration menus (discussed in Chapter
3). Each of the buttons reflects its profanity delay function.
At times during start-up, the display will scroll text giving a question requiring a yes/no answer. At
these times, the WAIT AND EXIT button will flash, indicating “yes” and the REBUILD button will be
lit solidly, indicating “no.” All other buttons will be off. Usually, the “yes” answer is expected.

1) BYPASS Button
Toggles the unit in and out of bypass. While bypassed, the LED flashes and the audio path through the BD600+
is bypassed either electronically or by a relay. Pressing this button while bypassed will take the unit out of by-
pass. This button is also used to exit from configuration mode.
2) Input Status
These LEDs indicate whether the BD600+ is configured for analog or digital input. If the digital input
LED is flashing, it indicates that the unit is not locked to the sample sync input.
3) CONFIG Button
Enters configuration mode.
See Chapter 3 for information on Configuration.
4) Level Meters
Two 10-segment LED bar graphs show audio input levels. These graphs act as meters and may be used
to align the equipment to ensure that appropriate audio levels are presented to the BD600+.
5) PANIC Button
In profanity delay mode, dumps the entire delay, and either plays a jingle from the card or mutes the
output for a configurable period. During this process the delay is filled in real time.
See More Information on the PANIC feature on page 17
6) WAIT FOR SAFE Button
In profanity delay mode only, initiates or cancels the wait for safe mode, which is used to start a show
with a safe amount of delay.

7) WAIT AND EXIT Button
In profanity delay mode only, initiates or cancels the wait and exit process, which exits quickly from
delay.
8) REBUILD Button
In profanity delay or precision delay mode, starts or stops rebuilding the delay. In precision delay configuration mode, decrements the current delay amount digit.
9) RAMP TO ZERO Button
In profanity delay or precision delay mode, instructs the unit to start or stop ramping toward 0.00 delay. In precision delay configuration mode, this button increments the current delay amount digit.
10) SNEEZE Button
This button is used to cut off microphone audio. If delay is greater than 0.00, the unit will reduce the
delay while SNEEZE is held. In configuration mode, this button sets an individual value back to factory defaults.
11) Delay Amount Bar Graph
This 15-segment LED bar graph indicates current delay as a fraction of maximum delay or, in precision delay configuration mode, indicates which digit of the delay value is selected. This display is also
used for visual cues during configuration mode. The right-hand segment also flashes to indicate card
and serial remote control activity.
12) 4-Character Display
The 4-character LED shows delay amount values, text information, and configurable parameter values.
13) Card slot
A Compact Flash card (of the type often used for digital cameras) may be used to store jingles for play
back during PANIC operation or as Station Breaks (BD600E+ or BD600W+only), and also for software maintenance.
14) DUMP Button
In profanity delay or precision delay mode, deletes a segment of audio in order to stop an undesirable
audio segment from being transmitted. This button is illuminated when the unit is in profanity delay
mode and the amount of delay meets or exceeds a preset safe amount. It is illuminated in precision de-
lay mode when the delay is at the configured amount. In precision delay configuration mode, this button sets the delay to the minimum amount.

5) Wordclock in
An external Wordclock signal may be used as a
sample clock source. A Wordclock signal will
usually offer a more stable clock source than
that supplied by an AES/EBU signal.
See page 9 to use Wordclock
6) Wordclock out
The BD600+ outputs a Wordclock signal of its
current sample clock – this may be used to synchronize other equipment to it.
7) RS232 Control Connector
This is a female 9-pin DB9 connector supplied
to connect a remote computer or terminal. The
remote computer or terminal can control all
functions of the BD600+ including configuration. This connector is only functional if there
is no USB connection.
See page 41 for information on RS232 remote control.
This connector may also be used for software
maintenance purposes.
Digital Audio Inputs and Outputs
These are XLR differential AES/EBU connections for stereo input and output channels.
8) AES/EBU in

control signals.
16) Activity Indication
These LEDs will flash when there is a change
of state on the adjacent inputs.
17) General Remote Input
This DB25 female connector has 16 bipolar
optoisolated inputs which can be individually
programmed for use to either control BD600+
functions or to feed the corresponding General
Remote Output.
See page 36 to configure these inputs.
18) General Remote Output
This DB25 male connector has 16 open collector outputs which may be individually programmed to supply BD600+ status or a delayed version of the corresponding input.
19) Network Connector
This is a Gigabit Ethernet connector for connection to the WheatNet IP network.
20) USB
This connector looks like a serial port when
connected to a computer. It can be used for remote control and updating. Note that connecting this port to a computer disables the RS232
port – only one of them can be used at a time.
A device driver must be installed to use this
with Windows 7.
See Installing Windows Drivers on page 54
Chapter 2 Operation
BD600+Profanity Delay Chapter 2 Operation Page 7
Analog
The BD600+ provides XLR differential audio connections
for two input channels and two output channels. When bypassed, the audio pins of each input channel are connected
to the audio pins of each output channel using a relay. The
unit is automatically bypassed when power is disconnected
or turned off. Note that neither pin 2 nor pin 3 should be
left unconnected or you will get more noise and distortion
than signal. Be aware that the ¼” jack inputs are not supported by the bypass function and should not
normally be used.
Analog Outputs
These male XLR connectors provide a differential balanced audio output with a maximum level of +24dBu and
a nominal level of -4dBu. Pin 1 is grounded to the case of
the external XLR connector. Pin 2 is +phase and pin 3 is –
phase.
Each connection may also be used as an unbalanced line.
The BD600+'s XLR analog audio output connectors are
male. Pin 1 is grounded. Connect pin 2 to your center conductor and connect pin 3 to pin 1. Both pins 2 and 3 must be connected at all times.
Analog Inputs
These female XLR connectors provide differential balanced audio input. The input level has a maximum value
of +24dBu and nominal level of -4dBu. Pin 1 is grounded.
Pin 2 is +phase and pin 3 is –phase.
Although the inputs of the BD600+ are balanced, you can
still use them with an unbalanced line. The BD600+ XLR
analog audio input connectors are female. Pin 1 and pin 3
would be grounded, while pin 2 is your audio signal. Both
pins 2 and 3 must be connected at all times.
In the case of an XLR to XLR balanced line (differential)
cable the shield should be left disconnected on one end
(usually on the end connected to an instrument output).
This helps to prevent ground loops. The use of balanced
connections is recommended.
Digital
These cables are differential with a shielded twisted pair.
For short distances microphone cables can be used, but
for longer distances and permanent installation a digital grade twisted pair cable is recommended.
AES/EBU input, XLR
The BD600+'s connector is female. Pin 1 is shield, 2 and 3 are differential.

Page 8 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
This chapter describes how the BD600+ is operated from the front panel using factory default configuration values. Optional remote control and configuration are described in later chapters and appendices.
Installation
Rack Mount
The BD600+ should be mounted in a grounded standard 19-inch rack using washers to avoid damaging
the front panel overlay. The rack should be well ventilated and in a dry and dust-free environment so
heat and moisture won't cause damage or degradation of performance. If rack units above or below the
BD600+ are hot a suitable gap should be left to allow cooling.
Connect AC and Turn On Power Switch
The BD600+ will automatically configure itself to operate over an AC supply voltage range between
100V and 240V, 48-62Hz.
Since the unit is electrically out of the audio path when in bypass mode (unless configured otherwise),
there is normally no reason to need access to the rear panel power switch. The power-up mode is selected by the configuration and is the same regardless of whether power is applied via the rear panel
switch or via connecting the AC to an already switched-on unit. The unit may be left powered on even
if the rack's power is to be disconnected.
Immediately after the unit is switched on, the front panel will be fully illuminated. After a second, the
display will change to show LOAD, followed by the software version number. At this time the unit will
read the front panel buttons. If any buttons are pressed, the unit will perform a special start-up function
(see Appendix D). If no buttons are pressed, the unit will complete its start-up, showing LOAD again. After a second, the display will show and the BYPASS button should be illuminated. This combina-
tion of LEDs indicates that the unit is powered on and in bypass mode.
Note that the BD600+ can be configured to go immediately into on-line mode - see Chapter 3 for details.
Level Meters
There are two 10-segment LED bar graphs to display input level information. These graphs act as meters and may be used to align the equipment so appropriate audio levels are presented to the BD600+.
The meters indicate the levels at the digital signal processor and are calibrated in decibels. The top
LED is red. The next two are yellow, and the bottom seven are green.
The red LED is lit if the level is above +24dBu. The remaining LEDs indicate approximately -3dB, 6dB, -9dB, -12dB, -15dB, -18dB, -21dB, -24dB, -40dB below the +24dBu reference level. Before
V1.4 the above reference level was the BD600+’s clip point, about 26dBu.
When the BD600+ is being operated correctly, most of the LEDs will be lit (NOT the
red one) when a loud signal is being received.

Connect analog audio inputs
Connect audio inputs to the two female XLR connectors on the rear panel. It is safe to connect and disconnect to the rear panel while the power is turned on. The inputs will probably come from a mixer
board. Supply an audio source at a level just below clipping. The BD600+'s level meters indicate input
level. Adjust your audio source's output such that with a maximum input signal, the level meters ideally have all of the green segments and both of the yellow segments lit, but not the red segment. Since
the BD600+ has a very high dynamic range, it will give adequate performance on lower input levels.
Connect analog audio outputs
Connect audio outputs from the two male XLR connectors on the rear panel. It is safe to connect and
disconnect to the rear panel while the power is turned on.
Connect digital audio inputs
Connect the digital audio input to the female XLR connector on the rear panel. It is safe to connect and
disconnect to the rear panel while the power is turned on. There is no level control for the digital inputs
as these cannot overload.
To enable the digital inputs and disable the analog inputs, or vice-versa, press the BYPASS button
once or twice until the BYPASS button's LED is flashing, then press the CONFIG button until you see
3 AU, then press WAIT AND EXIT to see INPT. Now use REBUILD or RAMP TO ZERO to select ANA
or DIG as desired. After changing the input format you should also set the SYNC variable as appropriate
(see below).
Connect digital audio outputs
Connect digital audio output from the male XLR connector on the rear panel. It is safe to connect and disconnect to the rear panel while the power is turned on. There is no level control for the digital output as it cannot
overload. The digital audio output is always enabled, whether analog or digital input is in use.
Selecting the sample rate
The BD600+ uses digital processing for all internal operations and its sample rate can be selected in
various ways. The digital output is also at this sample rate.
To change the sample rate, press the BYPASS button once or twice until the BYPASS button's LED is
flashing. Now press the CONFIG button to enter configuration mode and press it again to go up
through the configuration levels until you reach 3 AU. Press the WAIT AND EXIT button twice to go to
the SYNC variable. The options are:
44.1K The sample rate is set to 44.1kHz using an internal quartz crystal source.
48K The sample rate is set to 48kHz using an internal quartz crystal source.
AES The sample rate is determined by the AES input.
WCLK The sample rate is determined by the Wordclock input.
DIG (BD600W+only) The sample rate is determined by the AES or the network, depending
on the selected input.
Note that automatic internal sample rate conversion allows satisfactory reception of an AES signal even when
the sample rate is not set to AES. This means that the unit could be set to 48K and satisfactorily receive a digital

Document Version 2.3
input at 44.1kHz. Note that the AES output rate will be that set by SYNC - in this case 48K, meaning that the input
and output AES rates will be different.
Best results with digital inputs, will be normally achieved when the sample rate is set to match the input signal.
Wordclock will often give a more stable sync source than the AES signal.
If either AES or WCLK is selected but does not have a suitable input signal, the display and the DIGITAL input sta-
tus LED will flash, indicating lack of lock (meaning that the BD600+ is unable to synchronize with the signal).
During normal operation outside bypass mode, if the unit is synchronized to AES or WCLK and the signal becomes
unsuitable, the display will scroll NO LOCK. In bypass mode, the displayed bars will flash.
If the sync source becomes unlocked, the system will revert to the configured fallback mode (FLBK). This may be
either MUTE or ANAlog. If ANAlog is selected, during fallback mode the analog input LED will light while the digi-
tal LED will flash.
Notes and Warnings for AES/EBU Operation
The AES/EBU source must be stable before putting the unit in-line. If your AES/EBU source's sample rate
changes, or if the AES/EBU is disconnected, or if the AES/EBU audio source is turned off while the
BD600+ is processing audio (in-line and powered on), the BD600+ may add artifacts to the audio, or may
indicate a failure with an error message (NO LOCK).
The BD600+'s purpose is to store audio and play it back with a delay. If the rate of audio into the unit
changes while audio is stored, the audio played from the delay will change pitch. Thus, if the AES/EBU
source's sample rate changes or stops altogether (cable is disconnected), the BD600+ may play out audio
with a significant pitch shift! If the unit falls back from AES/EBU to analog input at a different sample rate,
there will be a pitch change in the audio already delayed through the unit. Your digital system must be set
very close to either 44100 or 48000 samples per second, or using the fallback option in the BD600+ will
allow several seconds of pitch changed audio to pass.
From the above, it will be clear that when using digital audio on air it is essential that all signals are of suitable quality and that a solid lock be achieved. These issues apply to all digital audio connections, not just
those involving the BD600+.
The BD600+ is designed to operate with sampling frequencies between 32K and 50kHz. If SYNC is set to AES or
WCLK and an incorrect sync source of above 50kHz is presented the unit will switch to 48kHz sampling and at-
tempt to sample rate convert the received AES signal to this rate. When it detects that an AES signal below
50kHz is again present, it will return to the original settings.
Using Wordclock
Wordclock is a square wave signal at the sample rate. Typically it is generated by a central timing
source and sent directly to all units with a digital input. Using Wordclock as a sync source in this way
allows tighter synchronization with reduced timing jitter which will maintain the best audio quality
across the installation.
Using Wordclock in a “daisy chain” configuration where it is fed through each piece of equipment de-
feats its purpose, as it will be degraded, however subtly, as it passes through extra circuitry. The best
configuration is where it is generated by a central high quality timing clock and then fed directly and
separately to each unit that requires it.
Understanding BD600 Profanity Delay Functions
BD600+Profanity Delay Chapter 2 Operation Page 11
Document Version 2.3
Wordclock Termination
Because a Wordclock signal is a high frequency digital signal, certain steps must be taken to be sure it
is not degraded when it is fed along a cable. These issues become more important for long cables.
1) The characteristic impedance of the cable and connectors should match that of the Wordclock
source. Wordclock cables are usually made with RG-59/U cable which has a characteristic impedance
of 75 ohms. Other cables may be made with RG-58/U “Thin Ethernet” cable which has a 50 ohm im-
pedance. Contact the manufacturer of your Wordclock source to find what impedance should be used –
75 ohm is the most common.
2) The end of the cable furthest from the Wordclock source must be terminated
with a resistance matching the Wordclock source and cable impedance. The
BD600+ has a jumper position inside (JP500, just behind the Wordclock connector) where a jumper may be installed to supply a 75 ohm terminating impedance – this jumper is normally not installed, meaning the input is un-terminated. It
is usually more convenient to use an external BNC T-piece and terminator, avoiding the need to open up the unit to change or check the termination.
With multiple destinations only the one at the end of the cable needs to be terminated – intermediate destinations need not and should not be terminated. These
should be connected by the use of a BNC “T” connector or splitter attached di-
rectly to their inputs so as to ensure the shortest possible stub length. Using multiple terminations is must be avoided, because (for example) twice 75 Ohm in
parallel gives 37.5 Ohms which is the wrong value for termination and also increases loading on the source.
Understanding BD600 Profanity Delay Functions
This section uses a tape recorder delay as an analogy to describe how the Eventide digital broadcast
delay behaves when used as a profanity delay. The digital broadcast delay can be likened to a tape recorder with some new features. A basic tape recorder profanity delay would look like this:
When the delay is placed in line, the microphone (audio source) is connected to the record head while
the transmitter is connected to the play head. This introduces a delay determined by the speed of the
tape and the distance between the tape heads.
In our analogy the speed of the tape is
constant. The distance between the heads
is measured in seconds and there is
enough room between the tape heads for
eight seconds of delay. Factory default
values are used whenever a time or duration is mentioned – for example, while the
SAFE time is stated as four seconds, it can
be configured to a different value.
The Eventide system offers the following features:
Understanding BD600 Profanity Delay Functions
Page 12 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
REBUILD - Increase the delay gradually
This feature allows the time between the play head and record head to be increased, in a subtle and
transparent way. At the start the play head and record head overlap (no delay). The record head is
slowly moved to the left until eight seconds of delay exists. The Eventide rebuild process does this in
about 120 seconds without causing a pitch change in the audio. Rebuild is used to recover from a
dump without having to go to a break. It can also be used to increase the delay time to allow for multiple dumps.
RAMP TO ZERO - Decrease the delay gradually
This feature is similar to rebuild except that the record head is moved to the right, in a subtle and transparent way, again taking a few minutes. When the record head reaches the play head, the unit is at live.
RAMP TO ZERO is used to exit from delay when the call-in portion of a program is over. Ramp to
zero performs a “time compression” operation, in that the audio plays out faster than real time.
WAIT FOR SAFE - Bring delay from live to 4 seconds quickly
When the wait for safe process is started, the tape is bypassed so the transmitter gets live audio. The
record head is moved to the left by 4 seconds. After 4 seconds of recording, the transmitter is reconnected to the tape delay. There is now a 4-second delay. Note, since the initial 4-second segment of audio will be repeated at the play head, it is up to the user to prevent the live audio from going over the
air. This feature is used to start a show coming from a network news feed, traffic report or other nondelayed program.
WAIT AND EXIT - Decrease the delay to 0 seconds quickly
This front panel feature is a method of quickly reducing the delay to 0.00 seconds. This process marks
where on the tape the record head was when wait and exit is started. When that piece of tape reaches
the play head, the record head is moved to the play head, decreasing the delay suddenly to 0.00 seconds. Use this command when a call-in show needs delay but where a break to non-delayed operation
is required.
SNEEZE - Edit the delay before a bad noise happens
This feature is used to stop the record process temporarily. While the SNEEZE button is pressed, the
record head moves toward the play head at the same speed as the tape, not recording any audio, until
the SNEEZE button is released (at which point the record head stops), or until the record head reaches
the play head, at which point silence is played out.
DUMP - Edit the delay after a bad noise happens
DUMP is used to edit several seconds of audio from the delay. Pressing DUMP moves the record head
four seconds toward the play head (or up to the play head, whichever is less). This causes the most recent four seconds of audio from the microphone to be discarded, including the bad noise.
PANIC – lose all delayed audio and play a jingle while delay is rebuilt
The PANIC function allows recovery from an undesirable signal by instantaneously moving the record
head up to the playback head to dump all the delayed material. It then moves the record head a distance
from the playback head corresponding to the length of a jingle or configured mute time.
It then either plays a jingle from a Compact Flash card or mutes the output for a configurable time, allowing an external cart machine to be cued.
Understanding BD600 Profanity Delay Functions
BD600+Profanity Delay Chapter 2 Operation Page 13
Document Version 2.3
Once the jingle or mute is complete, the delay will be partially filled, allowing the show to continue
seamlessly after the inserted jingle.
See page 17 for more information on the PANIC feature.
Insert or Station Break Insert – insert another audio source into the program material
Insert functions cause the playback head to move away from the record head at the speed of the tape.
This means that new audio continues to be stored into the delay while the inserted material is playing
and none of the material already on the tape is lost. Once the insert operation is over, the playback
head stops moving and the oldest audio from the tape starts to play out.
The amount of delay in use will be increased by the length of the insert. Clearly in this example there
will be a mechanical limit to the movement of the playback head which will determine how long an
insert may increase the delay time – on the BD600+ this maximum delay time is about 80 seconds.
This function may only be accessed through remote control.
Operating as a Profanity Delay
Page 14 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
The BD600+ may be used as a broadcast profanity delay - this is its primary function and factory default mode. When power is first applied to the BD600+, the unit's audio inputs and outputs are bypassed through a relay. Pressing the BYPASS button places the unit in-line with 0.00 seconds delay. If
the audio levels are adjusted properly, there should be no perceptible difference when the unit is
switched in. Note that since the BD600+ by default uses true relay bypass, there might be a slight
click. The 4-digit display will now read 0.00 which indicates no delay. The red indicators on several of
the buttons will be lit, showing which buttons are valid choices. The lighting of the indicators changes
depending on the BD600+’s state (or mode). Since the unit is at 0.00 seconds delay and in-line, it will
be in live mode. The following is a list of the few different modes in which the unit may be placed:
Note that the BD600+ may be configured to power up or exit bypass in different modes. See Chapter 3 Configuration for more de-
tails.
Modes
• bypass and configuration - delay is set to 0.00 seconds, the audio is bypassed directly from input
connectors to output connectors.
• live - bypass relays are open (unit is in-line), delay is set to 0.00 seconds.
• static - bypass relays are open (unit is in-line), delay is not changing.
• rebuild - bypass relays are open (unit is in-line), delay is slowly increasing.
• ramp to zero - bypass relays are open (unit is in-line), delay is slowly decreasing. Unit goes to live
when it reaches 0.00 delay.
• wait for safe - bypass relays are open (unit is in-line), delay is filling with audio, but outputs are
seeing input audio without delay. Unit switches to rebuild mode when safe delay time is reached.
If wait for safe is cancelled, the unit will return to live mode.
• wait and exit - bypass relays are open (unit is in-line), input audio is not going into delay, but out-
put audio is coming from the delay. The delay length is reducing rapidly. The unit will go into live
mode when it reaches 0.00 delay. The SNEEZE button is disabled. If wait and exit is cancelled, the
unit will return to the delay value it had when wait and exit was started.
• sneeze - bypass relays are open (unit is in-line), input audio is not going into delay, but output au-
dio is coming from the delay. The delay length is reducing rapidly. When the SNEEZE button is
released the unit will go back to the previous mode.
• panic - bypass relays are open (unit is in-line), input audio is going into the delay but is not heard
until the panic operation is complete. A jingle is played from the Compact Flash card or the outputs
are muted to allow an external audio source to be used. The unit will enter rebuild mode once the
jingle is complete or the configured mute period is over.
• insert or station break - bypass relays are open (unit is in-line), input audio is going into the delay
but is not heard until some time after the insert operation is complete. A jingle is played from the
Compact Flash card or the outputs are muted to allow an external audio source to be used. The delay length is increased by the length of the inserted audio.
Functions and Features
By default on power-up the BD600+ is in bypass mode. Press the BYPASS button to put the BD600+
in static mode. The delay is now at 0.00 seconds. After delay build is initiated and until the delay is reduced to 0.00 seconds, all audio should pass through the BD600+ before going to the transmitter to
avoid audible discontinuities.
Operating as a Profanity Delay
BD600+Profanity Delay Chapter 2 Operation Page 15
Document Version 2.3
Starting a Show Segment with REBUILD
This process is used to start a show in a simple manner, allowing the guest or dial-in caller to be enabled in less than two minutes. The host customarily uses this period for an introduction or monologue.
As a show starts, the delay is set to 0.00. Pressing the REBUILD button starts a process by which the
delay is slowly increased. During the rebuild process the REBUILD button's indicator will flash.
In less than two minutes the BD600+ will have enough delay built up to be 'safe' for a caller to be
placed on the air. The DUMP button will light up to confirm this and the delay amount will show 4.00
seconds and be increasing. If so configured, a rear panel output line will allow an external relay to be
closed, enabling the phone line.
After a few minutes, the delay will reach maximum and the REBUILD button's indicator will turn off.
The rebuild process is complete, and the delay enters static mode. However, the unit remembers that it
rebuilt to maximum, so, if SNEEZE or DUMP is used, after the SNEEZE or DUMP button is released,
the delay will automatically rebuild back to maximum.
Starting a Show Segment with WAIT FOR SAFE
This process is used to start a show rapidly. The guest or dial-in caller are enabled immediately after
the studio goes on air. Before beginning, the transmitter is not getting its source from the BD600+.
The operator needs to know, or to set, the configuration value of safe time (default is 4.00 seconds).
At safe time (or more) seconds before the studio goes on-the-air the operator presses the WAIT FOR
SAFE button.
The host begins talking immediately. When the DUMP button illuminates:
The WAIT FOR SAFE process has completed.
The SAFE relay output is enabled.
The engineer or host fades the output of the BD600+ into the transmitter. (See note below)
The host may begin taking dial-in callers. The BD600+ drops into rebuild mode and slowly completes
building up to maximum delay.
Note: During the 4-second period that wait for safe is running and the WAIT FOR SAFE button's indicator is flashing, the microphone audio is passed directly to the BD600+ outputs. It is usually undesirable to have that audio pass over the air. Use a mixer or other control to disable that audio until the
show is scheduled to start.
Starting a Show Segment with PANIC
If a suitable jingle or other audio is recorded onto a Compact Flash card in the card slot, the segment
may be started by hitting the PANIC button, causing play back of the jingle from the card. During this
time the host may start talking, typically an introductory monologue, which will be recorded into the
delay. Once the jingle has completed, the monologue starts to play out and the unit goes into rebuild
mode.
See More Information on the PANIC feature.on page 17
Ending a Show Segment with RAMP TO ZERO
This process gradually reduces the delay and takes a variable amount of time up to a few minutes.
During the show, the BD600+ would usually remain in rebuild mode at maximum delay. Whenever
SNEEZE or DUMP is used, the unit rebuilds back to maximum. To end the show, press RAMP TO
ZERO. The delay will reduce in several minutes to 0.00 while the RAMP TO ZERO button's indicator
flashes. During ramp to zero the DUMP and SNEEZE buttons will continue to be available, but an eye
should be kept on how much time is actually still available to be dumped or sneezed away. To stop the
ramp to zero process, press the RAMP TO ZERO button. The unit will go to static mode (delay not
changing). The ramp to zero process may be resumed, or another function may be started.
Operating as a Profanity Delay
Page 16 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
Once the ramp to zero process is complete, the unit will be operating at zero delay (live).
Ending a Show Segment with WAIT AND EXIT
This process rapidly reduces the delay and takes the time displayed on the BD600+'s front panel indicator, typically 8 seconds or less.
At the end of the show, after the last word is spoken, press the WAIT AND EXIT button. All of the
audio delayed in the BD600+ is played out in real time until the delay reaches 0.00. The WAIT AND
EXIT button's indicator flashes until the process is complete. Input audio is ignored by the BD600+
during this process. When the delay reaches 0.00, the unit goes into live mode at which time input audio is passed directly to the outputs.
If the WAIT AND EXIT button is pressed erroneously, the process may be cancelled by pressing the
WAIT AND EXIT button again. The unit will go back to the delay it had before WAIT AND EXIT
was pressed and will be static (delay not changing).
DUMP Button
This button has several functions. The primary purpose of this button is to stop a profanity from going
out over the air. This button is illuminated when in-line with a safe amount of delay (specified by safe
time). Here is a list of modes and how the DUMP button works in each:
In rebuild or ramp to zero
DUMP causes the unit to delete several seconds (configurable) from the delay line starting with the
most recently input audio information. The amount dumped is configurable and defaults to 4.00 seconds. When the DUMP button is pressed, the dump amount is subtracted from the current delay. If the
displayed delay is lower than the dump amount, the delay is reduced all the way to 0.00. After DUMP
is released, the unit continues with the previous mode. Note: even if the unit is no longer rebuilding,
having already reached full delay, the unit will still return to rebuild mode after DUMP is released.
In wait for safe
DUMP will cancel the wait for safe operation and return the unit to zero delay.
In precision delay configuration mode
DUMP causes the delay to be reduced to its minimum value (0.010 seconds).
In bypass, live, or wait and exit
DUMP has no function.
SNEEZE Button
This button is used to cover up a predictable interruption to a program like a sneeze, cough or comment to the caller or engineer, or some other undesirable noise. If the unit is in-line (not bypassed) in
profanity delay mode and not in wait for safe or wait and exit mode, this button will stop accepting input audio while it is held. The delayed audio will continue to be played out, reducing the delay amount.
This would make the listener unaware that the mute occurred. If the delay reaches 0.00, or is at 0.00
when SNEEZE is pressed, the audio is muted. When SNEEZE is released, the unit goes back to the interrupted mode. In simple terms – press button, sneeze, release button.
Delay Amount Display
The display consists of a bar graph and a 4-digit numerical display. The numerical portion shows the
delay amount in seconds with optional fractions of seconds. The factory default is to show seconds and
thousandths of seconds with the decimal point appropriately placed. The bar graph indicates what portion of maximum the unit is delaying. For instance, if the unit is delaying at 3.50 seconds and the unit
is configured to have a maximum of 8 seconds of delay, 6 of the 15 bar graph segments are lit.
Operating as a Profanity Delay
BD600+Profanity Delay Chapter 2 Operation Page 17
Document Version 2.3
The display is configurable to be blank, or to show 1, 2, 3 or 4 digits of resolution of delay length. In
bypass the display will show ‘----‘.
If the unit is in-line, and configured to use AES or Wordclock as a sync source and it loses lock, the
display will scroll “NO LOCK.”
See Notes and Warnings for AES/EBU Operation on page 10
More Information on the PANIC feature
The PANIC feature is designed to offer some protection against undesirable input audio when the delay value is unsafe. It is also useful as a convenient way to get into delay at the start of a show.
Hitting the PANIC button causes the delay to be instantly set to zero and then filled with input audio in
real time. During this time, a jingle may be played from the Compact Flash card, or the output muted.
If the input is being monitored, DUMP or SNEEZE may be used in the normal way.
If a suitable jingle file is selected on the card it will be played, and the panic mode will terminate at the
end of playback. If the length of the jingle is greater than the configured maximum delay value it will
play to the end, but the delay will only be filled to the configured maximum value.
See Chapter 3 to select the jingle file.
If no suitable jingle is selected on the card (or the card is not present) and the PANIC (PANC) time is not
configured to OFF, the output will be muted for the PANIC time, allowing an external cart to be played
if desired. After this time, the panic mode will terminate, with the delay filled to the configured
PANIC time.
See Chapter 3 to configure this.
Once the panic mode has terminated, the unit will go to rebuild and the delay will play out, starting
with the audio immediately after the PANIC button was hit. A panic operation may be ended early by
hitting the PANIC button again. (Prior to V1.4, this would mute the audio until the operation completed).
If the PANIC time is configured to OFF and no suitable jingle is selected on the card, the PANIC feature will be disabled and the button will be unlit.
Jingle files on the card
Jingle files can be recorded on a PC (IBM-compatible Personal Computer) using any suitable software.
These can be saved to a suitable Compact Flash (CF) card using a commercial CF card reader/writer.
These are usually connected to the PC via USB (Universal Serial Bus) and are widely available.
The files must be 16-bit stereo .WAV files longer than 1.0 seconds, created with the sample rate to
which the BD600+ is to be operated. If these requirements are not met, either the BD600+ will not recognize them, or they will be played at the wrong speed.
The BD600+ can support up to four different jingles per card – they must be named ONE.WAV,
TWO.WAV, THREE.WAV and FOUR.WAV respectively. These names may be in upper or lower
case. The active jingle can be selected either by changing the configuration variable JING, or by remote
control. If the selected jingle is either not valid or not present, or there is no card in the slot, a BAD
JINGLE message will appear briefly. The JBAD status will be displayed if configured.
See Chapter 3 to configure jingle selection.
See Appendix A for information on remote control.
Cards should not be removed or inserted when the unit is not bypassed.
Operating as a Profanity Delay
Page 18 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
The BD600+ is not a live performance instrument and requires a second or so to respond to a jingle
change.
When Jingles should not be used
When Jingles are to be used it is recommended that the JBAD status be displayed (BD600E+,W only),
as this gives advance warning of possible problems. These may occur for the following reasons:
• The card is not present or not readable
• No jingle is selected => See Chapter 3 to configure jingle selection
• The selected jingle is not on the card
• The selected jingle has the wrong format
• The selected jingle is being prepared for use (about one second is needed after inserting a card or
changing jingle selection or between playbacks).
• A jingle is currently being played.
Operation as a Micro Precision Fixed Delay
BD600+Profanity Delay Chapter 2 Operation Page 19
Document Version 2.3
The BD600+ may be used as a fixed stereo delay line, adjustable from 0.010 seconds to 19.999999
seconds, adjustable in microseconds (0.000001 seconds) or thousandths of film/video frames. Operation is straightforward, with several front panel buttons serving secondary duty as fixed delay controls.
There are two ways to enter precision delay mode – the first method is from configuration mode. Go
into bypass mode.
• In bypass mode the display shows .
• Press the CONFIG button. This puts the unit into configuration mode (display shows CONF).
• Now press the CONFIG button again. You are now at the "on-line" configuration level (display
shows 1 ON).
• Now press the WAIT AND EXIT button. The display should now show RUN.
• Now press the RAMP TO ZERO button repetitively (stepping through run options) until the dis-
play shows MPD.
• Press the BYPASS button to exit configuration mode. The display should show .
• Now press BYPASS to put the unit in-line. The unit will be in micro precision delay mode.
To return to profanity delay operation, press BYPASS, then CONFIG twice, then WAIT AND EXIT.
The display now shows RUN. Now press SNEEZE to return to the factory default setting of the run pa-
rameter. Now press BYPASS to get out of configuration mode.
The second way to enter precision delay mode is to select MPD as the maximum delay time (DLAY).
Then the maximum delay is determined by the fixed delay settings, and normal broadcast delay functions may be used to enter and exit precision delay mode. For example, if you REBUILD to maximum,
once the fixed delay value is reached the unit will enter precision delay mode. RAMP TO ZERO or
WAIT AND EXIT may be used to return to profanity delay functionality. In this mode, the fixed delay
value becomes the SAFE value, and the DUMP button illuminates when it is reached.
Controlling the Fixed Delay
In precision delay mode the profanity delay buttons have their normal functions for delay values of
100mS and above. Below 100mS they are inactive. This allows you to ramp up to or down from the
precision delay time, which now becomes the SAFE value.
There is one addition – the CONFIG button is also active. If CONFIG is selected it will flash, and the
meanings of the buttons change to allow the fixed delay value to be changed. In this mode, the only
operable buttons are BYPASS, WAIT FOR SAFE, WAIT AND EXIT, REBUILD, DUMP and RAMP
TO ZERO. The buttons behave as follows:
• BYPASS takes the unit off-line. Always valid.
• WAIT FOR SAFE selects the digit to the left. Valid if lit.
• WAIT AND EXIT selects the digit to the right. Valid if lit.
• REBUILD decrements selected delay digit. Valid if lit.
• RAMP TO ZERO increments selected delay digit. Valid if lit.
• DUMP sets the delay to its minimum value (10mS).
Operation as a Micro Precision Fixed Delay
Page 20 Chapter 1 Introduction BD600+Profanity Delay
Document Version 2.3
The bar graph below the four-digit display flashes to indicate precision delay configuration mode and
shows which of the four visible digits is selected for adjustment. The presence of the decimal point indicates that the four digits shown are the ones, tenths, hundredths and thousandths digits. Use the
WAIT FOR SAFE and WAIT AND EXIT buttons to step through the selected digits. The following
illustration shows a 7.012345-second delay as the WAIT AND EXIT button is pressed six times. Press
WAIT FOR SAFE repeatedly to step back to the first digit. Press CONFIG again to get back to normal
precision delay mode.
Notes on Precision Delay mode
• The minimum delay setting the BD600+ will allow is 10 milliseconds. The absolute delay time
through the unit will depend on whether analog or digital inputs or outputs are being used.
• Broadcast profanity delay functions such as rebuild, dump or sneeze are only operative in pre-
cision delay mode at delay values of 100 milliseconds and above.
▪ The fixed delay writes data continuously into the 20-second buffer. Changes in delay value
changes the position of the play head, not the record head. That means that, if the delay length
is adjusted by ear, the user doesn't have to wait for new input audio to check the adjustment. As
an example, while listening to an audio source, try adjusting the seconds digit upward. It is easy
to play the same 1-second piece of input audio ten times.
▪ Small changes to delay values are smoothed, meaning that in most cases such changes can be
made on air. A large change will still be smoothed, but a soft click or a discontinuity in program material may be apparent.

Chapter 3 Configuration
BD600+ Profanity Delay Chapter 3 Configuration Page 21
Document Version 2.3
There are a number of adjustable values used by the BD600+. Configuration mode gives access to
these values and allows them to be changed. This chapter covers the configurable variables for the
basic BD600+. Configuration of optional features is covered in the appendices.
The configuration mode is operated by the front panel buttons, which are used to navigate through a
map of configuration variables. The WAIT FOR SAFE and WAIT AND EXIT buttons are used to
move left and right across the map. The REBUILD and RAMP TO ZERO buttons are used to adjust
the values of individual variables. The CONFIG button will move to the left side of the map and, if
pressed while already on the left side, will move up through the levels. The SNEEZE button is used to
reset a selected variable to the factory default.
See the side-bar for a partial map of the configuration parameters. Complete information is provided
in a following table. This map is a combination of the maps for both the BD600+ and BD600E+.
Basic Operation Example
From bypass mode, press CONFIG. The display
changes to show CONF. Press CONFIG again to move up
the map. The first press will move to 1 ON. The next will
move to 2 TI. Now press the WAIT AND EXIT button a
few times to move over to the REBvariable (rebuild
time). Notice that the SNEEZE button's LED is not lit.
This means that the REB variable is set to the factory de-
fault. Use the RAMP TO ZERO button to change the
value. Notice that the SNEEZE button lights up. Press
the SNEEZE button to reset the parameter back to factory default.
Another Example
If the BYPASS button is not illuminated, press
BYPASS. Next, press CONFIG. Once the display
shows CONF, press the RAMP TO ZERO button. The
display changes to 1 ON.
Now press the WAIT AND EXIT button once.
The display changes to RUN. To check the run mode,
press the REBUILD or RAMP TO ZERO button. The
display changes to show LIVE, indicating “go into live
mode when exiting from bypass.” To change the run mode, press the RAMP TO ZERO button. Use the
REBUILD and RAMP TO ZERO buttons to go up and down through the four possible values for the
run parameter.
Press BYPASS to exit from configuration mode and return to bypass mode. Any changes made will
remain until they are reconfigured.
Password Protection
If desired, configuration mode may be password protected. The display will then show P--- when the
CONFIG button is pressed. To enter configuration mode, the user must first press and hold the
CONFIG button, then a single other button (password) and then release the CONFIG button. Pressing
the wrong button will return the unit to bypass mode. This procedure has been made deliberately ob-
scure to ensure authorized use. Change or disable the password button using the PASS configuration
variable. => See page 30 for more information.

Configuration Variables
BD600+ Profanity Delay Chapter 3 Configuration Page 29
Document Version 2.3
A number of configuration variables are specific to either the Basic Remote or Extended Remote models – these are covered in separate appendices.
BYP
Bypass mode
When the BD600+ is bypassed, internal relays normally connect the analog and digital outputs to their
respective inputs. This also occurs when the unit is powered down. In some circumstances it may be
preferable to change this behavior, for example, if the unit is fed with an analog signal but the output is
taken from the digital output. In this case, DSP bypass may be preferred, where the inputs and outputs
are connected electrically according to the INPT configuration. The BD600+ may also be configured to
MUTE its outputs when bypassed.
DISP
Display Digits
The number of digits after the decimal point showing the current delay amount in profanity delay
mode. The BD600+ has a four-digit numeric display used to show the delay amount in hundredths of
seconds. As the delay rebuilds or ramps to zero, the last digit can change rapidly enough to be distracting to the operator. By changing the number of display digits to two, one, or even none, this source of
distraction can be reduced greatly or eliminated. Since the operator may only need to know that the
BD600+ is in rebuild, and whether it is safe or not, the operator may choose not to have the delay time
presented in such high resolution.
DLAY
Delay Length
Delay length controls the maximum length of the broadcast delay. This adjustment may select a delay
length of from 4.0 to 80.0 seconds. Select a length allowing the operator to dump multiple offending
phrases without impairing operator efficiency. A length which is too short will not allow the operator
enough time to delete offending speech, while a length that is too long increases the amount of time
required to exit from the delay at the start of a break or end of a show. This delay length may be exceeded by the use of an Insert or Station Break operation.
If MPD is selected, the maximum delay is determined by the precision delay setting, allowing the normal profanity delay functions to be used to enter and leave precision delay mode.
DUMP
Dump Amount
This is the amount of time deleted from the delay when the DUMP button is pressed in profanity delay
mode. If the DUMP button is pressed when less than this amount of time is in the delay, then the entire
contents of the delay are deleted.
FLBK
Fallback
If AES/EBU or Wordclock is selected as a sync source and there is no suitable signal present, the unit
will declare an out-of-lock condition. If the unit is in-line (not in bypass) and an out-of-lock condition
exists, the four-digit display will scroll the message NO LOCK. If the FLBK (fallback) variable is set to
ANA(analog), then the analog input audio will be used until lock is restored. The analog input will be
sampled at either 44100 or 48000, the sample rate chosen being whichever of the two rates is closer to
the AES/EBU sample rate last received by the unit (or 48kHz if no AES/EBU signal has been present
since power-up). The AES/EBU outputs will be active and the rate will be the same as the input analog
sample rate. If the fallback variable is set to MUTE, the unit will mute the outputs until lock is regained.
FRAM
MPD Frames Display
The MPD setting is normally be displayed in seconds (FRAM = OFF). It can instead be displayed in film
or video frames by setting FRAM to 24, 25, 29 or 30 as appropriate. Use 29 for the NTSC drop frame rate
of 29.97 fps.
Configuration Variables
Page 30 Chapter 3 Configuration BD600+ Profanity Delay
Document Version 2.3
INPT
Input source
This variable determines whether the ANAlog or digital input is used. If it is changed, it will usually also
be necessary to change the SYNC variable accordingly. BD600W+adds WNET as a source, selecting the
configured WheatNet-IP network source.
See Selecting the sample rate on page 9,
JING
Select current Jingle
Select which of the four possible jingles (ONE, TWO, THRE or FOUR) on the Compact Flash card is active.
Note that the jingle file will only be recognized if it is in the correct format. A BAD JINGLE message will
appear briefly if an unsuitable or absent jingle file is selected.
Jingles should not be changed while they are being played as this will cancel the playback operation.
See Jingle files on the card on page 17 for more information.
LOCK
Lock Front Panel
The front panel lockout feature allows most front panel buttons to be disabled, allowing protection
against undesired operations when the unit is to be exclusively remote controlled. When LOCK is ON, all
keys except for BYPASS and CONFIG will be disabled. Pressing any other key will cause the display
to flicker, and an ‘L’ to be displayed.
PANC
Panic Mute Time
If no suitable jingle is found on the Compact Flash card (or if the card is not inserted), this variable determines how long the outputs will mute when PANIC is pressed. In this case, if it is set to OFF, the
PANIC feature is disabled, otherwise this variable will be ignored if the selected jingle is present.
PASS
Password
Where some modicum of security is needed, this value may be changed to the identifier of a front
panel button. If set, a user would have to go to BYPASS, press and hold CONFIG, then press the selected additional front panel button before releasing CONFIG, in order to get into configuration mode.
A selection of NONE indicates that no second button is required.
Configuration Variables
BD600+ Profanity Delay Chapter 3 Configuration Page 31
Document Version 2.3
POWP
Power-Up mode
This controls whether the BD600+ goes into bypass at power-up (BYP), goes directly into processing
(INLN), or goes to the state it was in when last powered down (PREV). If INLN is selected, the unit will go
directly to the in-line mode selected by the RUN configuration variable. Note that changes made within
a few seconds of power down will not be remembered.
If PREV is selected, the unit will go to the state shown below:
State at previous power down
State on next power up

PULS
Heartbeat Indicator
A Broadcast Delay unit like the BD600+ is often left powered up in line for long periods. Since it may
not be used often, and yet is expected to react faultlessly should inappropriate material be detected,
there is value in giving a confidence indication while it is not active. This value, when set, causes the
CONFIG light to discreetly flash according to the selected time, showing that the unit is alive.
REB
Rebuild Time
The rebuild time is the period the BD600+ will need to build from zero delay to maximum delay or to
ramp from maximum delay to zero. This is used to start up the delay or recover from DUMP. The factory default is 120 seconds, or two minutes, for a typical eight second maximum delay. The actual time
to complete a rebuild may be slightly different, depending on the audio content, and the settings of several other configuration parameters. Values above 9999 seconds will be displayed in minutes, for ex-
ample, instead of 12000 (seconds) you will see 200M.
The displayed time for this variable will change in proportion if DLAY is changed, in order to keep the
same quality of signal during rebuild or ramp to zero.
This value should be set following suitable listening tests and will normally be proportional to the
maximum delay value, but should be increased for broadcasts with music content or multiple speakers.
RUN
Run mode
This controls which mode the BD600+ enters when leaving bypass mode. The selections are live, wait
for safe, rebuild, and micro precision delay. Each of these modes is described elsewhere in this chapter. The factory default is live.
SAFE
Safe Time
In many broadcasting situations a control output from the broadcast delay will be used to control a telephone connection or auxiliary microphone input. The control input is only connected when enough
delay has been built up to allow the operator to delete offending vocals. The delay length which must
exist to allow the audio connection is called the safe time. The safe time is related to the reaction time
of the operator and the complexity of what would be called offending speech. Normally, the safe time
is several seconds. Since wait for safe is used to quickly build the delay to an amount long enough to
be safe, the safe time is also the time value used by wait for safe. The DUMP button is illuminated only
when the delay is longer than the safe time, unless configured otherwise.
Configuration Variables
Page 32 Chapter 3 Configuration BD600+ Profanity Delay
Document Version 2.3
SBRK
Station Break Duration (BD600E+,W only)
On the normal BD600+ the length of a Station Break Insert is fixed at 4.0 seconds – on the BD600E+
and BD600W+it may be set to an amount between 2 and 8 seconds or determined by a JINGle saved on
the CF card.
See Station Break Insert on page 35 for more information on this feature.
SEND
Delay Time Export Format
The current delay value can be transmitted automatically over RS232 to update an external display or
computer. This is sent every time it changes as an ascii value terminated with either binary 0 (END0), a
carriage return (CR - binary 13) a carriage return/line feed sequence (CRLF binary 13,10) or a line feed
(LF - binary 10). The default is OFF, meaning that the delay value is not sent. If the RS232 command
port is disabled (BAUD set to OFF) this function will operate at a baud rate of 9600.
SHOW
Delay Display Type
When using the BD600+ in Broadcast Delay mode, the main display normally shows the amount of
delay USED. If the BD600+ is mainly being used for Insert or time-compression operations, it can be
helpful to know the amount of delay that is unused, as this determines the length of the maximum Insert operation that can be performed without losing input audio – in this case the display mode could
be set to FREE. The bar graph builds from left to right in either case.
SRCE
Source
This selects the amount of signal from each channel that will be fed into the signal processor for use in
determining best time-to-process. If the unit is unable to pick good times-to-process, artifacts will be
introduced into the output audio. This value may be set to one of five values, from left to right, LEFT
LCEN CENTR RCEN RITE. LEFT indicates all of channel 1 and none of channel 2. RITE(right) indicates all of
channel 2. CENTR(center) indicates an even sample of both. LCENindicates a blend of mostly left (chan-
nel 1) and some right (channel 2). This adjustment does not affect the audio signal levels seen at the
outputs.
If only one channel is used for input, set the source to that channel (LEFT or RITE). If one channel is usually of poorer quality (i.e., a telephone), give the other channel priority. For instance, if channel 1 is the
local microphone and channel 2 is telephone, you might select LEFT. If channel 2 is a mix of local microphone and telephone, and channel 1 is never used, select RITE.
SYNC
Sample Rate Source
This variable selects whether the sample rate will be set to one of the two fixed sample rates (44.1 48 ),
or will be set according to the AES/EBU input AES or the Wordclock input WCLK. If the AES/EBU digital inputs are in use, this would typically be set to AES or WCLK, but can be set to 44.1 or 48, in which
case sample rate conversion will be enabled, allowing the digital signal to be received regardless of its
sample rate (within reason). This variable also sets the sample rate of the AES/EBU output – for example, if it is set to 48, a received 44.1kHz digital input will be converted internally to 48kHz, producing
a 48kHz digital output. BD600W+- if WNET is selected as the signal source, SYNC will be fixed at DIG, as
the BD600+ sample rate must be set by the network. If SYNC is set to AES or WCLK and the unit is un-
locked, the display will flash.
TMP0
Tempo Modification
Controls how much the tempo is allowed to vary in order to improve the quality of audio processing.
This will normally be set to the default value.
Configuration Variables
BD600+ Profanity Delay Chapter 3 Configuration Page 33
Document Version 2.3
THRS
Threshold Level Adjustment
This value sets the threshold level used for the detection of pauses or silence. The default value has
been optimized for normal usage. It may be necessary to adjust this value if the level of ambient noise
is high. Great care should be taken when adjusting this value, as setting the threshold too high or too
low may impair the catchup operation. The effects of changing this setting are best observed while rebuilding. This will normally be set to the default value.

The BD600+ with the Basic Remote Control feature has four configurable inputs and two configurable
multi-pole relay outputs.
Basic Remote Connector
The basic remote control connector is a 16-pin Euroblock socket on the rear panel. A range of plug-in
connectors is available to facilitate wiring. A terminal block type connector is supplied with the
BD600+.
Outputs
There are two outputs available:
RLA1 – this is a two pole changeover (DPDT) relay rated at 1A 30V DC or 125V AC.
RLA2 – this is a two pole relay with one changeover contact and one normally open contact, both rated
at 1A 30V DC or 125V AC. Note that RLA2 is driven in common with the DUMP light, so if its
source is changed from the default SAFE value, the DUMP light will not operate as described in this
manual.
These outputs can be configured by using normal configuration mode operations to get to 5REM and
then selecting RLA1 or RLA2 as appropriate. The relays may be activated as below:
OFF never
ON always (useful for testing)
BYP when bypassed
CNF during configuration mode
WFS when WAIT FOR SAFE is active
WAE when WAIT AND EXIT is active
REB when REBUILD-ing
RMP0 when RAMP-ing TO ZERO
SAFE when the delay is greater than the con-
figured safe time
SNEZ when SNEEZE is active
DUMP when the DUMP button is pressed
LIVE when the delay is at 0.00
STAT when the delay value is stable and non-
zero
PANC when in panic mode
FULL when the delay is at maximum
MUTE when the output is muted
SBRK during a Station Break Insert operation
(see below)
The default value for RLA1 is DUMP and for RLA2 is SAFE.

Station Break Insert
This remote-only function mutes the output for 4.0 seconds (variable on BD600E+) while continuing
to enter input audio into the delay – typically, the RLA1 or RLA2 outputs will be configured to trigger
an external cart machine to seamlessly insert a Station Identification Break or other jingle into the program material without loss of input audio which can then be time-compressed to make room for it. To
use this feature successfully on a BD600+, the current delay value must be 4 or more seconds below
the maximum. On completion, the delay value will be 4.0 seconds longer than when it was triggered,
or the configured DLAY value, whichever is shorter.
On BD600E+, a Station Break Insert may be programmed to JING, which will cause the current selected
jingle to be played directly from the CF card rather than requiring an external cart machine and mixer.
This jingle may in practice be a Station Break, a promotion or a commercial.
See Insert Operations below for more information.

The BD600E+ with the Extended Remote Control feature has 16 configurable parallel inputs and 16
configurable parallel outputs, as well as an RS232 (serial) delay input and output.
Extended Remote Connectors
The extended remote connectors are DB25 for parallel input and output, and DB9 for serial input and
output. See Appendix E for connection and electrical information.
Parallel Outputs
There are 16 identical parallel outputs. These may be used as status (tally) outputs to show the operational state of the unit, or they may be fed with a version of the corresponding input delayed by the
current delay amount.
These outputs can be configured by using normal configuration mode operations to get to 6EXT and
then selecting OUT1 or OUT2 etc as appropriate. The outputs may be activated as below:
OFF never
ON always (useful for testing)
DLIN a delayed version of the corresponding
parallel input
BYP when bypassed
CNF during configuration mode
WFS when WAIT FOR SAFE is active
WAE when WAIT AND EXIT is active

Parallel Inputs
There are 16 input controls, IN 1 to IN16. These inputs are opto-isolated and can be driven with a
voltage of either polarity between 5 and 25 volts. They may be configured to remotely duplicate existing push buttons or to provide other functions that cannot be achieved with the normal front panel controls. These inputs may also be configured to feed the corresponding outputs, delayed by the length of
the audio delay. It is possible, but not always wise, to combine the delay and control functions. Note
that most of these inputs do not function when the unit is bypassed.
The activity light on the rear panel will light briefly if any of these inputs change.
OFF the control input is disabled. It can still
be used as a delay source.

Control Signal Delay
If a parallel output is configured to DLIN, it will output the corresponding input delayed by the current
audio delay, whether Broadcast Delay or MPD. This is useful for synchronization of control signals
with the delayed audio.
In this case, the corresponding input will normally be set to OFF to prevent it also controlling a
BD600+ function.
Insert Operations
The BD600E+ supports an Insert feature, allowing a variable length announcement, commercial or station break info to be inserted into a delayed program which can then be automatically time-compressed
to make room for it. This operation is similar to the Station Break Insert described on page 35, with the
difference that the length of the insert is determined by an external input. During the Insert operation
playback of delayed audio ceases and the output of the BD600+ is muted while input audio continues
to be fed into the delay. Typically, one of the remote outputs is used to operate a relay to externally
mix the inserted audio - alternately this operation may be performed manually. Once the insert is complete, the BD600+ reverts to normal broadcast mode and continues the playback of the delayed audio.
The following applies to both Insert and Station Break operations.
Dump or sneeze operations may be performed while Insert or Station Break operations are active if the
BD600+ input is being monitored.
An Insert or Station Break (SBR) operation is real time by nature, so that inserted audio is heard imme-
diately, while the input to the BD600+ will be delayed according to the current delay value, which will
be increased by the length of the insert. During Insert and SBR operations the current delay is allowed
to exceed the configured Maximum Delay DLAY if this is less than the maximum allowable amount (80
seconds). At the end of a SBR or Insert operation, if the current delay is greater than DLAY, the unit will
go into a Ramp To Zero mode until the DLAY value is reached.
As an example, suppose that DLAY is set to 20 seconds, and that the current delay is 10 seconds. A 30
second SBR or Insert is performed. During this operation the live input audio will be stored in the unit
and the delay value will increase at real time until the end of the operation when it will read 40 seconds
(10 + 30). The unit will then start to ramp the delay downwards until 20 seconds (DLAY ) is reached
when the delay value will become static. The result is that the input audio is time-compressed to make
room for the SBR or Insert. Once the unit has ramped down to 20 seconds it is back in normal Broad-
cast Delay mode. If one of OUT1-16 is configured to >MAX, this will be active while the delay value is
above the configured DLAY value.
IMPORTANT – if an Insert or Station Break operation causes the current delay value to reach the
maximum value of 80 seconds, all new input audio will be lost until the delay value is reduced – when
the delay is full there is nowhere to save the input audio. For this reason it is recommended that the
sum of the configured DLAY value and the longest possible Insert or SBR not exceed 80 seconds. If one
of OUT1-16 is configured to TOP, this will give a warning that input audio is being lost, but this event
should be strenuously avoided.
Insert or SBR operations should be considered live performances and testing and rehearsal are highly
recommended before on air use.
Appendix B BD600E+ Extended Remote Control
Page 40 Appendix B Extended Remote Control BD600+ Profanity Delay
Document Version 2.3
Serial input and output
The BD600E+ can delay a single RS232 channel by the same amount of time as the audio delay. This
allows control signals or time indication to be synchronized with the output audio. The baud rate, number of bits and parity may be configured. The number of stop bits sent is fixed at two. Typically the
source signal will be connected to the RS232 delayed input, a 9 pin female PC type connector, and the
delayed RS232 will be supplied by the corresponding 9 pin male connector. A LED indicator on the
back panel indicates activity – it is lit when the delay contains RS232 data.
The serial delay has a capacity of over 80000 characters. This means that it can handle continuous
transmission at 9600 baud with the full 80 seconds of delay, but can be overwhelmed at higher rates.
Typically this feature will not be used with high bandwidth data as normal time or control signals involve only a few characters per second.
To be sure that the delay is not overfilled, the serial data should be limited to 1000 characters per second at the 80 second full delay, and proportionally more at lower maximum delay values. The unit can
accept full speed transmissions at any of its supported baud rates – the limit described is the maximum
number of stored characters at any given time.
Note that neither the RS232 handshake signals are not delayed, nor any returned data (negative delay is
difficult, even for Eventide).
One possible source of confusion is that during a Wait for Safe operation no data will emerge from the
delay. This is normal and correct - during this operation the delay setting is increasing at the rate of one
second per second – meaning that no data can reach the end of the delay before the delay time is increased. Once the Wait for Safe operation has finished, the data in the delay will appear.
After V1.4, the serial delay will be set to zero when the unit is bypassed. Any data that is in the delay
will be immediately output when the unit enters bypass – it will not be lost.
Appendix C RS232 Remote Control
Page 41 Appendix C RS232 Remote Control BD600+ Profanity Delay
Document Version 2.3
A BD600+ can be completely configured and operated from a personal computer or user-supplied custom control system. The female 9 pin RS232 connector on the rear panel is the mate for the male COM
port on a typical desktop computer. The BD600+ operates as Data Communication Equipment (DCE) the same as a modem. A straight through (pin 1 connected to pin 1, etc.) cable may be used to connect
the BD600+ to a unit operating as Data Terminal Equipment (DTE), such as a personal computer.
The default characteristics of the RS232 connection are 9600 baud, 8 bits, 1 stop bit and no parity
(9600, 8, 1, none). The BAUD rate may be changed via the configuration system.
The following table is the pin number, label, and direction relative to the BD600+. The label is the
same as used by the terminal or PC that will be connected to the BD600+. Since the BD600+ is DCE,
the labels and direction are opposite in meaning to those of the DTE definitions.
Pin 1 DCD (out)
Pin 2 RxData (out)
Pin 3 TxData (in)
Pin 4 DTR (in)
Pin 5 Gnd
Pin 6 DSR (out)
Pin 7 RTS (in)
Pin 8 CTS (out)
Pin 9 RI (out)
The BD600+ does not require the hardware control lines. Only RxData, TxData and Gnd are necessary.
The BD600+ only sends messages as a response to a poll from a host computer. The host computer
must not send a message unless it has received a > character (hex 3E) or unless it has not heard from
the BD600+ in 100mS. An overflow or bad message will be answered with a E> (hex 45, 3E).
The right-hand display bar segment will flash when receiving RS232 information. A terminal or PC
terminal emulator can usefully be used to debug and demonstrate command sequences.
Protocol
The following page has a list of mostly single byte commands which are available to the host computer. The table lists the response generated by the BD600+. All commands will generate a response:
!> indicates command processed with no other data returned
X> indicates command not valid at this time
E> indicates serial port error or unrecognized command
Redundant commands will be answered with a !> or X> as appropriate. End of sneeze and mute will
put the unit back in the mode it was in before the sneeze or mute started. All transmitted and received
bytes are ASCII characters between ‘0’ and ‘_’ or 30 hex and 5F hex, as well as line feed (0A hex) and
carriage return (0D hex).
Protocol notes
The unit is allowed to send an error message (E> or X>) at any time. Any interrupted message is terminated when the error message is sent, so the > character will be permission for the external device to
send a new command. Command letters may be upper case or lower case. The command set is based
on that of the Eventide BD500 with necessary differences.

0 requests static at 0 delay puts the unit in-line. If the unit was in BYPASS and the RUN variable specifies
MPD or MPD1-4, MPD mode will be entered, using the selected delay. Otherwise
the unit will enter profanity delay mode at zero delay (live).
1 increments MPD digit note: MPD must be entered via configuration change to the run mode parame-
ter.
2 decrements MPD digit
3 selects MPD digit
5 starts mute use the K command to un-mute. Works in MPD and profanity delay modes.
The system will continue whatever it was doing before, but the output will be
silent. Mute will be cancelled on entering BYPASS.
4 not used
6 initiates or cancels station
break insert see page 35 for information on the Station Break Insert feature.
7 initiates ramp to bypass performs ramp to zero and then automatically switches to bypass.
8 initiates wait for bypass performs wait and exit and then automatically switches to bypass.
9 not used
@ go to MPD initial character must be followed within 1 second by one of 0 to 4 - will enter
MPD mode using either current MPD value (value 0), or MPD value 1 to 4
(value 1,2,3 or 4). This will last until the next bypass, after which the unit will
return to its configured mode.
A initiates wait and exit
B switches to bypass mode
C requests config values shows the current settings of each of the config values. This long response in-
cludes multiple records, each consisting of a 4 byte config variable name, fol-
lowed by an ASCII equal sign (=), followed by a 4 byte config value, followed
by hex 0D,0A (carriage return, line feed). The last record will be followed by a
>. None of the 4 byte values contain >. The records correspond to configuration
variables described in Chapter 3 and consist of ASCII characters of the set 0
through 9, A through Z, space and dash. Records will be padded with trailing
spaces where necessary to bring them up to 4 bytes.
D performs a dump note: this command will NOT drive RLA1 or RLA2, even if configured for
DUMP.
E entire config table dump entire config table with all variables and all available values. This long
response includes multiple records, each consisting of a 4 byte config variable
name, followed by an ASCII equal sign (=), followed by one or more 4 byte
strings, each containing config values, separated by spaces, followed by a space
and then hex 0D,0A (carriage return, line feed). The last record will be fol-
lowed by a >. None of the 4 byte values contain >. The records correspond to
configuration variables described in Chapter 3 and consist of ASCII characters
of the set 0 through 9, A through Z, space and dash. Records will be padded
with trailing spaces where necessary to bring them up to 4 bytes. Note that the
REB values will depend on the current DLAY value.
F go to static at full delay if the RUN variable does not specify MPD, the unit goes to in-line, static and at
full delay.
RS232 Command Set
BD600+ Profanity Delay Appendix C RS232 Control Page 43
Document Version 2.3
G go to next config variable steps to next config variable. Responds with normal !>. Use X to request cur-
rent config variable name and value. See also C, E, N, Q, V, X, and Y commands.
H go to static at current delay cancels a rebuild or ramp to zero.
I enter panic mode
J set delay followed by a numerical delay value terminated by a space or <return>. No
more than one second is allowed to elapse between characters, and no characters apart from 0-9 and decimal point and space characters are allowed. If the
unit is in MPD mode this command sets the MPD time, otherwise the delay
cannot exceed the current DLAY value.
When not in MPD mode, the DLAY value can instead be temporarily set by this
command by terminating the value by an asterisk, e.g. J57.5*. This will last until the unit next starts or enters bypass, at which point the DLAY value will be
restored to the configured value.
K ends a sneeze or mute or station break
L requests levels three-character response is left channel level followed by right channel level
and terminated with >. Levels are reported using one digit ASCII hex of range
0 through 9, and A. Example: 25> is left channel level of 2, right channel of 5.
M requests mode response is three characters of the form m!> where m is the current mode.
Modes are A <wait and exit>, B <bypass>, H <static>, I <panic>, L <live>, M
<mute>, P <micro precision delay>, R <rebuild>, S <sneeze>, W <wait for
safe>, Z <ramp to zero>.
note: zero delay and maximum delay are not modes; if the unit reaches maxi-
mum delay while in rebuild, it switches to static mode, while if it reaches zero
delay while in ramp to zero, it switches to live mode.
N next config value sets the current config variable to the next value. When the maximum value is
reached, the next will be the minimum. Responds with normal "!>". Can only
be used in bypass mode. Use X to request current config variable name and
value. See also G command.
P requests MPD delay value response is 8-digit (including decimal point) ASCII value of delay in millisec-
onds, followed by position indicator (1, 2, 3, 4, 5 or 6), followed by >. Note:
This does not change the mode to MPD. Example: if delay is 1.1 seconds and
the 4th digit is selected, the response will be “1100.0004>”.
Q resets config stepping points at start of configuration mode. Used with C, E, G, N and V, X, and Y
commands to make configuration changes to the BD600+.
R initiates rebuild
S starts a sneeze see K command for end-sneeze.
T requests current delay response is 4-digit decimal ASCII value of delay in 10s of milliseconds, fol-
lowed by >. The BD600+ can be configured to automatically send delay values
whenever they change by use of the SEND configuration variable.
U requests current delay as hex sends delay amount in 10s of milliseconds as hexadecimal using 4 chars of
ASCII hex followed by H>.
V Eventide Factory Defaults sets factory defaults for all config variables (except baud rate). System must be
in bypass.

The RS232 commands allow the front panel of
the BD600+ to be completely replicated in
function (and in form) by a remote device. A
computer with a terminal emulator may use
these commands to prove that all of the information and control are available. Use the T, M
and P commands to watch modes and delays
change as commands are issued.
Configuration Mode Commands
The RS232 configuration commands step
through the configuration variables in much the
same way the front panel does. Use the G command to step to the next variable. Use the N
command to step through values for a single
variable.
Most values will be used by the BD600+ immediately after they are changed, so care must
be taken not to change those that may cause undesirable artifacts on air.
M requests mode
B switches to bypass mode
0 switches from bypass to in-line
C dump values for all config variables
E dump possible values for all variables
G go to next config variable
N next value for this variable
Q back to first variable
V Eventide Factory Defaults
X examine current variable
Y first value for this variable
Example configuration operations
Note that you must wait for a prompt before
sending each character.
To change the rebuild rate from whatever it
happens to be to 240, you can send
Q G G G G G G G G Y N N N N N.
(Spaces are shown to increase readability and
would not be sent.) This sequence says: go to
first variable, then step through the variables to
the REB variable, then set it to the first value,
then step through to the 6th value which is 240
(for an 8.0 seconds DLAY value).
In order to change the full delay amount, the
unit has to be placed into bypass. This sequence
will change the maximum delay to 4.0 seconds
and put the unit back in-line.
Q G G G G G G G Y N B 0.
Note that if you issue the B command while
the unit is already bypassed, you will get an error message. Your sequence may expect the error message and ignore it.

Start-up Switches
The BD600+ has operations which are used in the factory to prepare the unit to be shipped. Each operation is performed by turning on the unit while holding down a button until the version number message goes away. Some of them may post a “do you want to..” type message, with the WAIT AND
EXIT button blinking to indicate “yes” and the REBUILD button lit steadily to indicate “no.”
Restore Factory Defaults - PANIC button
This function restores all configuration values to the factory defaults. In the event of serious system
malfeasance, this function should be tried, and if it does not restore normal behavior, do the following
to clear memory.
Clear all Memory – RAMP TO ZERO button
This function clears all memory and returns the unit to the state at which it left the factory.
Perform Production Self-Test - SNEEZE button
This function goes into a series of self tests. Many of these tests cannot pass unless loop-back connectors are installed on audio and control connectors. These tests should only be run under instruction
from Eventide as some of them can erase internal programs.
Other Functions
The remaining front panel keys are unused at this time or are reserved for factory purposes.

Parallel Outputs
The parallel outputs are of the open-collector type, meaning that when active, the output is pulled to
ground by a transistor. A 5V supply capable of a maximum of 500mA is available on the connector,
along with a clamp input that may be useful when driving relays.
The outputs can handle a maximum voltage of +50V DC in the off state and a maximum current of
0.5A per output in the on state (0.2A if all outputs driven) – operation above these limits will damage
the output circuitry. It is recommended that suitable relays be used to handle currents and voltages
above 100mA/25V to protect the unit from possible damage or overheating.

Notes
• None of the ground connections may be used as a safety ground – they are rated for low current
DC operation only.
• The Chassis Ground connection (1) may be used as a screen connection. It should not be connected
otherwise.
• If the +5V 0.5A supply (13) is used, output loads need only be connected from here to each output.
These would typically be LED indicators with suitable series resistors or small 5V relays.
• If an external power source is used, its –ve side should be connected to ground (6,11,12,14,19,24)
and its +ve side be used as the power source. Output loads should be connected between the output
signal (Out 1, etc) and the power source. The grounds are connected together inside the unit - for
low currents only one need be used.
• The clamp signal (25) is the common cathode connection for clamping diodes connected to each
output. If this is connected to the power source, it will prevent the voltage on each output from exceeding the power voltage. This would mainly be used for back-emf protection when driving relays
or other inductive loads.
• The driver chips for these outputs are socketed so that they can be easily changed if damaged –
U110 handles OUT1-4, U112 handles Out5-11, U111 handles Out12-16.

Parallel Inputs
The parallel inputs are opto-isolated and bipolar, meaning that they may be driven by a positive or a
negative voltage. This voltage may range between 5 and 25 volts.
One side of each input is commoned in groups of 4. By default, all these groups of common connec-
tions are tied together. This may be changed by the use of internal jumpers P100-103 – if these are all
removed the inputs will be isolated from ground and from the other groups of 4.

The BD600E+ serial input is wired to connect to a PC serial output, while its output is wired to look
like a PC serial output. RxData and the handshake lines (CTS, RTS etc) are not delayed or used by the
BD600+ and need not be connected in most cases – only TxData and Gnd will be required for many
applications..

Appendix F BD600W+ WheatNet-IP
Page 50 Appendix F WheatNet-IP BD600+ Profanity Delay
Document Version 2.3
WheatNet-IP is a product of the Wheatstone Corporation, which allows multiple pieces of audio equipment to pass audio and control signals over a Gigabit Ethernet network. The BD600W+can be connected to a WheatNet-IP network, usually as a slave of a "Blade." It should be noted that most networking issues are beyond the scope of this manual, and should be addressed directly to Wheatstone
Technical Support.
Connecting the BD600W+to a WheatNet-IP Network
To add a BD600W+to a WheatNet-IP network, you will need at least one Wheatstone Blade attached
to the network. This is because the BD600W+acts as a “slave” to the Blade. Before connecting the
BD600W+you will need its IP (Internet Protocol) address – this defaults to 192.168.87.239, and is displayed during the BD600+W’s startup sequence. The system can be configured by using Wheatstone’s
WheatNet-IP Navigator application, shown below.
First connect your BD600W+to the WheatNet-IP system using a suitable
network cable – this will probably connect to a Gigabit switch which is part
of your network.
The BD600W+is viewed as a “3rd Party Device” - to add it to the system,
click on the “3rd Party Devices” tab. This will show the window above.
Click the “Add…” button, and enter a suitable name and the BD600+W’s
IP address.
Leave the “TCP Port” and “Host Blade” values alone.
Appendix F BD600W+ WheatNet-IP
BD600+ Profanity Delay Appendix F WheatNet-IP Page 51
Document Version 2.3
Connecting Audio between the BD600W+and WheatNet-IP
The BD600+W's audio inputs and outputs will appear on the Navigator Crosspoint screen, shown
above. They can be identified by right-clicking on the Source or Destinations list and choosing
Show/Name-Location. The BD600+ sends a stereo output and receives a stereo input from the network, shown as Location BD600+ (assuming BD600+ was the name given on the "Third Party Devices" tab).
Note that the BD600+ audio output is always sent to the network, while its audio input is only received
from the network when INPT is set to WNET. In this case, SYNC can only be set to DIG, as the BD600+ must
run at the same sample rate as the network.
Appendix F BD600W+ WheatNet-IP
Page 52 Appendix F WheatNet-IP BD600+ Profanity Delay
Document Version 2.3
Connecting Control Signals between the BD600W+and WheatNet-IP
The BD600W+can receive 16 control signals from the network, and send 16 statuses to it. The meaning of these to the BD600W+are configured under 6EXT, Extended Remote Control Parameters. In this
respect, the BD600W+is similar to the BD600E+ - the difference being that the BD600+W's control
and statuses are logical network signals, rather than physical rear panel connections.
In WheatNet terminology, these logical control and status signals are known as LIOs (Logic Input or
Output). BD600+ LIOs can be studied by selecting the Blade to which the BD600+ is attached and
then clicking on the Sources or Destinations tab as appropriate. Click Add to create a new LIO.
The available BD600+ LIOs are shown in the Free Resources window, while the existing signals are
shown in the Source (Destination) window. Note that both BD600+ and Blade LIOs are shown with
the Blade as the Location. The only way to confirm the actual BD600+ LIOs is to look at the LIO Info
tab, which will list the BD600+ LIOs, showing their signal names and other info. The reader should
study the WheatNet-IP documentation for more information on configuring LIOs.
WheatNet related error messages
If the BD600W+shows an unlocked indication when INPT is set to WNET, this indicates a hardware problem in the BD600W+. This will be shown by flashing horizontal bars in Bypass, or a NO LOCK indication otherwise. The BD600+W's input will act as configured under FALLBACK.
A message saying no Wnet routing means that either the BD600+ audio input or output is not connected to another signal. This may be deliberate.
A message saying no Wnet CABLE means that the BD600W+is not connected to the WheatNet-IP network. This may be due to cabling issues or hardware problems.
If either the IP address is not displayed at startup, or INPT cannot be set to WNET, this indicates a hardware problem in the BD600W+.

Document Version 2.3
Changing the IP Address
The default IP (Internet Protocol) address for the BD600W+is 192.168.87.239. You may need to change
this value if it clashes with another piece of connected equipment, for example if you have more than one
BD600+W. The IP address for any piece of equipment must be unique - if you need to change it, obtain a
suitable value from your Network Administrator.
To change the IP address you will need an internet connection to the BD600W+and a software application
that can log onto it using the Telnet protocol. Again, your Network Administrator can assist. You will need
the current IP address to log on to it – this is displayed at BD600W+power up.
When the connection is made, you will see:

Warranty Information
BD600+ Profanity Delay Warranty Information Page 57
Document Version 2.3
LIMITED WARRANTY
The above-identified Eventide unit covered by this warranty is built to exacting quality standards and should give years of trouble-free
service. If you are experiencing problems which are not cleared up in this manual, your recourse is this warranty.
What the warranty does and does not cover
Eventide Inc. warrants the above-identified unit to be free from defects in workmanship and material under normal operation and service
for a period of one year from the date of purchase, as detailed below. At our discretion within the warranty period, we may elect to repair
or replace the defective unit. This means that if the unit fails under normal operation because of such defect, we will repair the defective
unit at no charge for parts or labor. We also assume a limited responsibility for shipping charges, as detailed below.
The warranty does not extend beyond repair or replacement as stated herein and in no event will we be responsible for consequential
or incidental damages caused by any defect, and such damages are specifically excluded from this warranty. Our sole obligation is to
repair or replace the defective unit as described herein.
The warranty DOES NOT COVER any damage to the unit regardless of the cause of that damage. The unit is a complex piece of equipment
that does not react well to being dropped, bounced, crushed, soaked or exposed to excessively high temperatures, voltages, electrostatic or
electromagnetic fields. If the unit is damaged for these or similar causes, and the unit is deemed to be economically repairable, we will
repair it and charge our normal rates.
The warranty DOES NOT COVER shipping damage, either to or from Eventide. If you receive a new unit from us in damaged condition,
notify us and the carrier; we will arrange to file an insurance claim and either repair or exchange the unit.
If you receive a new unit from a dealer in damaged condition, notify the dealer and the carrier.
If we receive the unit from you with apparent shipping damage, we will notify you and the carrier. In this case, you must arrange to collect
on any insurance held by you or your carrier. We will await your instructions as to how to proceed with the unit, but we will charge you
for all repairs on damaged units.
Who is covered under the warranty
The warranty applies to the original purchaser of a new unit from Eventide or an Authorized Eventide Dealer. Demo units are also covered
by this warranty under slightly different circumstances (see below). Units that are used, or have been used as part of a rental program, are
not covered under any circumstances.
It is your responsibility to prove or to be able to prove that you have purchased the unit under circumstances which effect the warranty. A
copy of your purchase invoice is normally necessary and sufficient for this.
If you have any questions about who is an Authorized Eventide Dealer, call us.
Units with the serial number plate defaced or removed will not be serviced or covered by this warranty.
When the warranty becomes effective
The one-year warranty period begins on the day the unit is purchased from an Authorized Eventide Dealer or, if the unit is drop-shipped
from Eventide, on the day shipped, plus a reasonable allowance for shipping delays. This applies whether or not you return your warranty
registration form.
When we receive a unit, this is how we determine whether it is under warranty:
1. If the unit was shipped from our factory within the past calendar year, we assume that it is under warranty unless there is
evidence to the contrary, such as its having been sold as used or rented, etc..
2. If the unit was shipped from our factory more than a calendar year ago, we assume it is not under warranty unless:
a) There is a warranty registration form on file showing that it has been purchased within the past year under appropriate
conditions.
b) You send a copy of your purchase invoice indicating warranty status along with the unit.
3. If the unit was used as a demo, the warranty runs from the date that it was received by the dealer. The original purchaser gets
the unexpired portion of that warranty.
When you send a unit for repair, you should indicate whether or not you believe it to be under warranty. If you do not say the unit is under
warranty, we will charge you for the repair and we will not refund unless the charge was caused by an error on our part. If you believe the
unit to be under warranty and you do say it is but we disagree, you will not incur any charges until the dispute is resolved.
Warranty Information
Page 58 Warranty Information BD600+ Profanity Delay
Document Version 2.3
Reading the above, you can see that it is to your advantage to send in the warranty registration form when you purchase the unit. If we
know who you are, we can send you updates and notifications, and advise you of our new products. It will also enable you to receive preshipment of certain parts.
Who performs warranty work
The only company authorized to perform work under this warranty is Eventide Inc., Little Ferry, New Jersey. While you are free to give
personal authorization to anyone else (or to work on it yourself), we will not honor claims for payment for parts or labor from you or from
third parties.
However, we and our dealers do try to be helpful in various ways:
1. Our dealers will assist, usually without charge during the warranty period, in:
a) determining whether there is a problem requiring return to the factory, and
b) alleviating user error or interconnection problems that may be preventing the unit from operating to its full
capability.
2. We are available for telephone consultation if the dealer is unable to assist.
3. If a part is found to be defective during the warranty period and you wish to replace it yourself, we will normally ship the part
immediately at no charge, provided your warranty registration form is on file. We reserve the right to request that the defective
part be returned to us.
Shipping within the 50 United States
You are responsible for getting the unit to our door at no cost to us. We cannot accept collect or COD shipments.
We will return the unit to you prepaid, at our expense, using an expeditious shipping method, normally United Parcel Service. In areas not
served by UPS we will ship by US Mail.
If you are in a hurry and want us to use a premium shipping method (such as air express, next day air, etc.), be sure you tell us and agree
to pay shipping charges collect. If you specify a method that does not permit collect or COD charges, remit sufficient funds to prepay
shipping.
Shipping outside the 50 United States
If you purchased the unit from a dealer in your country, consult with the dealer before returning the unit.
If you wish to return the unit to us, please note the following:
1. The unit must be prepaid to our door. This means that you are responsible for all shipping charges, including customs
brokerage and duties. When a unit is shipped to us it must be cleared through United States Customs by an authorized broker.
You must make arrangements for this to be done. Normally, your freight forwarder has a branch in the United States which can
handle this transaction. We can arrange to clear incoming shipments for you. If you want our assistance, you must notify us
before shipping the unit for repair, giving full details of the shipment, and including a minimum of $250.00 in US funds to cover
the administrative and brokerage expenses. Any balance will be applied to the repair charges or refunded. If a balance is due to
us, we will request a further prepayment.
2. All shipments will be returned to you collect. If this is impossible because of shipping regulations or money is due us, we
will request prepayment from you for the appropriate amount.
3. All funds must be in $US. Payment may be made by check drawn on any bank in the US, or by telegraphic funds transfer to
our bank. If you send US currency, be sure that it is sent by a method you can trace, such as registered mail. If you wish to pay
by Letter of Credit, be sure that it affords sufficient time for work to be performed and the L/C negotiated, and that it is free from
restrictive conditions and documentation requirements.
4. We reserve the right to substitute freight carriers. Although we will attempt to honor your request for a specific carrier, it is
frequently necessary to select a substitute because of difficulties in communication or scheduling.
This warranty gives you specific legal rights and you may also have other rights which vary from location to location.
