- DR-3000 SERIES DIGITAL AUDIO SYSTEM -
- A S
YSTEM OVERVIEW -
The DR-3000 SERIES DIGITAL AUDIO SYSTEM has been developed to meet all of your needs for Digital
Audio Repeaters, Low Level Processing, and Public Address Systems. The following sub systems are available:
¥ Digital Audio Repeaters (DR-3000, AB-3000)
¥ Digital Audio MiniRepeaters (DR-500, and AB-500)
¥ Audio Processing Modules (DR-4000)
¥ Intelligent Public Address System

Each of these can be used alone or as part of your overall audio system. When used together, all
you need to add to make a complete audio system are the power supplies, amplifiers and speakers.
DIGITALAUDIO REPEATERS :
A Digital Audio Repeater is a solid state replacement for loop and cartridge tape decks. All of our
Digital Audio Repeaters meet the demanding requirements for professional voice message, high quality
music, and sound effects reproduction systems.

Instead of using tape or any moving parts, a Digital Audio Repeater stores sounds digitally in
computer-style memory chips. Because it has absolutely no moving parts, a Digital Audio Repeater
never requires any maintenance. A sound on a Digital Audio Repeater will sound just as good twenty or
thirty years from now as it did on the day it was installed.

Each DR-3000 or AB-3000 is a complete stereo audio source. It can be used as two separate monophonic repeaters, or as a single stereo pair. Any number of DR-3000s can be plugged into one or more
card cages to provide any number of simultaneous audio tracks. Any number of DR-3000 repeaters can
be synchronized within 1/44,100 of a second for use as a multitrack bin loop tape deck replacement.
Multiple bin loops as well as independent repeaters can all be operated within the same card cage.
An AB-3000 is identical to a DR-3000, but comes in its own case and includes a power supply. It can
be mounted anywhere you need just one or two CD-Quality audio tracks. All you need to add are amplifiers and speakers. All configuration and commands for the AB-3000s are identical to those for the DR3000 Repeaters. An AB-3000 just wonÕt respond to commands for features for which it doesnÕt have the
necessary hardware. An example of commands that the AB-3000 canÕt use are those for the PA system.
You can record a sound into a AB/DR-3000 yourself, or send us a tape to do it for you 4. A recording
of the sound is first recorded into an IBM compatible or Macintosh computer that has a some sort of sixteen bit audio sampling hardware installed. The audio card in your computer takes your original audio
and turns it into digital computer data. This is stored in one of several industry standard file formats on
your computer. On an IBM compatible this will be a Ô.WAVÕ file. On Macintosh and Amiga computers an
ÔAIFFÕ file format is used. Most audio editing systems can generate these file formats directly. Sample
rates supported on the AB/DR-3000s are at 11KHz, 14.7KHz, 22KHz and 44.1KHz for audio reproduction at
bandwidths of 10 Hz to 5 KHz, 6.5 KHz, 10 KHz or 20 KHz respectively 5. Sixteen bit linear encoding gives a
dynamic audio range of 96 dB, which is identical to the sound quality from a Compact Disc (CD).
Once sampled, the .WAV or AIFF file is run through a small program which we provide to convert it
into the format the AB/DR-3000s can use. This program allows you to select from all the .WAV and AIFF
files on your computer to decide which ones will be loaded onto each AB/DR-3000. Up to 255 different
messages can be loaded onto each AB/DR-3000 card 6. You can set the amount of compression you
would like to use, and how low a level signal to use when doing silence evaluations. The compression
uses an algorithm similar to DolbyÕs, but with extensions to stop using any memory at all if an instant of silence occurs. The data compression alone gives you about a 4:1 reduction in the amount of memory a
sound needs 7. The silence removal can extend this even further.
The program compresses the data and divides it up into appropriately sized and formatted files for
use by the AB/DR-3000s. These files are then 'burned' into computer memory chips using a commercially available EPROM programmer, or sent to appropriate PCMCIA memory cards. These are then plugged
into the AB/DR-3000s 8. From this point on, the AB/DR-3000 can play back the sounds that have been
loaded onto it. Any of the different messages can be instantly accessed through the optoisolated inputs,
serial port or DMX-512 input. Any spiel on any card can be played through once or looped so that it repeats. Mono recordings can be directed to play through either the left, right or both outputs. You can
even play a mono recording out of both AB/DR-3000Õs outputs asynchronously. This is useful on long vehicles (like trains) where the same message must be played for the rear half of the vehicle at a slightly
later time.
Although 'data compression' saves the amount of memory you need to use, it makes it darned difficult to estimate the number of Eproms your recording will need until it has been digitized. The following
charts show the capacities with a variety of sounds using different sized Eproms:
4
Tapes can be sent on DAT (this is the preffered medium), cassette, 1/4Ó reel/reel, CD or video tape.
5
No matter the sample rate used, the AB/DR-3000 reproduces the sound at a full 44.1KHz update
rate. Because of this, and the lower efficiency of the compression at lower sample rates will give you, we
recommend that 44.1KHz samples be used in the majority of applications.
6
These individual messages are refered to by the industry standard term 'spiel' in this manual.
7
The actual compression ratios uou get depends on the sounds you are compressing. A clean
recording from a digital source will compress much better than one from a noisy recording.
8
A PCMCIA card requires a MCRD-1000 or MCRD-4000 installed on the AB/DR-3000 to hold it. A special card is available which allows a PCMCIA hard disk drive to be used.

Each AB/DR-3000 holds up to twelve Eproms. Using 27C080 Eproms, this will give you a capacity of
approximately eight minutes of mono or four minutes of stereo (at a four to one compression ratio) on
each card. If your recording needs more space than this, you can add memory expansion cards to the
AB/DR-3000s. Each MX-1000 expansion card holds another 32 Eproms. Each MCRD-1000 holds a single
PCMCIA memory card or a PCMCIA format hard disk drive 9, while a MCRD-4000 holds up to PCMCIA
memory cards. FLASH, RAM and EPROM types of PCMCIA cards are all supported.
With two or more MX-1000 memory expansion cards on a DR-3000, additional one inch wide spaces
will be needed within the card cage. Each AB/DR-3000 can support almost twenty-four hours of data
storage. The only limitation is the physical mounting of the memory expansion cards. Seven expansion
cards on a DR-3000 is the normal physical limit for card cage mounted systems. This forms a package
that takes up 4 inches of card cage space.
In AB-3000 AudioBricks there is room for up to two memory expansion cards. If you leave the lid off
the case, then you can add up to fifteen memory expansion cards to an AudioBrick.
The densities available on PCMCIA cards is such that we are currently supporting only one MCRD- ex-

Because of the hard diskÕs head access time, a hard drive equipped repeater must be used as a
stereo pair, or only play one mono audio track at a time.

pansion card on each AB/DR-3000 at one time. As of this writing, 175 MByte FLASH cards are (or soon will
be) available. These potentially give you instant access to up to 701 MBytes of memory. This translates
into almost nine hours of CD-quality audio storage on each MCRD-4000 equipped AB/DR-3000.
These AB/DR-3000s access their memory in sixteen bit wide words. For this reason you will always
need to use an even number of Eproms on all AB/DR-3000s. PCMCIA cards are sixteen bits wide, so they
can be added one at a time.
The AB/DR-3000 can support any type of EPROM memory chips from 27C040 (four Mbits or 512
KBytes) up to 27C080 (eight Mbits or 1 MByte). Note that all memory chips used with our AB/DR-3000s
must use ÔCMOSÕ technology. These use far less current and generate far less heat than the older
ÔNMOSÕ technology. CMOS memory chips can be recognized by the letter ÔCÕ following the numbers Ô27Õ
in their part numbers. Luckily, the older NMOS technology is pretty rare in these higher density memory
chips.
DIGITALAUDIO BUS:
The DR-3000 includes a powerful mixing bus that can be used to send audio signals between all the
DR-3000s in a set of interconnected card cages. There are 120 time slots available on the Digital Audio
Mix Bus, divided into two 60 channel ÔbanksÕ. Any DR-3000 can be configured to use either the first or
second 60 time slots, but not both. One ÔhiddenÕ channel from each bank is reserved for internal use by
the DR-3000s to relay GROUP START commands to all the other cards within the cage. Any single DR-
3000 can use up to four of the following functions:
1) Listen to any one time slot, and mix the audio signals found there into the left or right output
channels of a DR-3000. The ÔlevelÕ of this signal can be permanently fixed, or adjusted dynamically using:
a) 0-10 volt analog voltage inputs
b) DMX-512 input
c) RS-422 serial port
d) AB/DR-3000Õs front panel
2) Send the left or right DR-3000Õs repeater or output to any one time slot. The ÔlevelÕ of this signal
can also be permanently fixed, or adjusted dynamically using:
a) 0-10 volt analog voltage inputs
b) DMX-512 input
c) RS-422 serial port
d) AB/DR-3000Õs front panel
A simple example of the use of the Digital Audio Mix Bus would be where you have an installation
with a number of audio point sources with their own speakers, and a single background audio track that
you want to send to all the point source speakers. The background track would be sent to one time slot
on the Digital Audio Mix Bus and all the point source DR-3000s would then be told to listen to this time
slot. The background audio track is then mixed into all the point source outputs. The levels can be fixed
or configured to follow an external command.
A second example of the use of the Digital Audio Mix Bus is where you need to ÔchaseÕ an audio signal across a room to simulate movement. A single track on a DR-3000 can be used for the source signal. Its output would be sent to a single time slot on the mix bus. Additional DR-3000s or DR-4000s would
then be used to receive the signal by listening to the same time slot. An external signal from an
Animation Control System would then be used to adjust the volume on each of the DR-3000s to ÔchaseÕ
the audio across all of their speakers.
Other possible uses for the Digital Audio Mix Bus are:
¥ Implementing simple 'non-zoned' Public Address systems.
¥ Monitoring the audio in an attraction by feeding a number of audio tracks to a single monitor
speaker.
¥ Sub-woofer and multi-amplifier applications where the outputs of a number of DR-3000s are
fed to a single specially filtered output channel.
The Public Address system also uses sixteen of the time slots on the Digital Mix Bus from the first ÔbankÕ.

GILDERFLUKE & CO. ¥ 205 SOUTH FLOWER ST. ¥ BURBANK, CALIF. 91502-2102 ¥ 818/840-9484 ¥ FAX818/840-9485
These are unavailable to the rest of the audio system when the Intelligent Public Address System is used
on a DR-3000 installation. The PA System is unavailable if the repeater is using the second Digital Audio
Buss bank.
VOLTAGE CONTROLLED AMPLIFIER (VCA):
A Voltage Controlled Amplifier (ÔVCAÕ) is an electronic component which is used to adjust the volume
of an audio signal remotely by applying a control voltage. Although the AB/DR-3000s donÕt actually have
any real VCAs on them, several VCA functions are simulated inside the AB/DR-3000's Digital Signal
Processor (DSP). These functions can be used to adjust any of the different audio signals on the AB/DR3000s:
1) Left volume level.
2) Right volume level.
3) Left half muted level.
4) Right half muted level.
5) Left Bass level.
6) Left Treble level.
7) Right Bass level.
8) Right Treble level.
9) Digital Mix Bus input volume level. Any of the four possible inputs from the Digital Audio Mix Bus
can be adjusted remotely.
10) Digital Mix Bus Output volume level. Any of the four possible outputs to the Digital Audio Mix
Bus can be adjusted remotely.
The control signals for these ÔVCAsÕ can be fixed at a preset level or come from one of three different
sources. These sources are:
1) Front panel. Any of these signals can be set to be adjusted from the buttons on the front of
the AB/DR-3000.
2) DMX-512 input channels. Up to four DMX-512 channels can be used at one time.
3) Any one of the eight 0-10 volt analog inputs. (Only two of these are available on the outside
of an AB-3000, although the other six inputs are still available inside the unit if you need them.)
4) RS-422 serial port commands. The serial command structure allows up to eight different Ôvolume zonesÕ to be controlled.
When using the analog voltage inputs, the control signal is a simple 0 to 10 VDC signal just as you
would feed to a lamp dimmer. This can be fed to each card through any of the eight 'VCA BUS' lines
which are connected to all the DR-3000s in a cage. Any number of DR-3000s can use the same analog
VCA bus line. The pinout of the VCA Bus connector is compatible with the analog outputs from all of
Gilderfluke & CompanyÕs Animation Control Systems and MA-100 PA MASTER. Using the Intelligent PA system, commands from the PA STATIONS can be used to ramp the levels of these outputs up and down to
control the volume of a group of AB/DR-3000s. Serial commands sent to the MA-100 can also control
these outputs directly.
All the control functions are normalized for ÔlogarithmicÕ response. This means that a 50% control signal will give a 50% perceived volume level.
To keep external inputs from being set too high or too low, any signal that is controlled from an external input can be limited to within a user defined range. This range of adjustment can only be set
through the serially accessed configuration screens.
SHELVING EQUALIZER:
The Shelving Equalizer can be used to adjust the output filters of the AB/DR-3000 to compensate for
slight errors in the original recording, speakers or other parts of the installation. Although not a full graphic equalizer, these bass and treble controls can be used to cover a multitude of sins.
REAL TIME CLOCK:
A very accurate real time clock is available as an option on both the DR-3000 and AB-3000 AB/DR3000s. When this option is installed, the AB/DR-3000s can be configured to chime the quarter hours, toll
the full hours, and play any specific spiel at any specific time of the day or night. To keep from disturbing
6
GILDERFLUKE & CO. ¥ 205 SOUTH FLOWER ST. ¥ BURBANK, CALIF. 91502-2102 ¥ 818/840-9484 ¥ FAX818/840-9485
the neighbors, the hours of operation can be set for each day of the week.
There are eight schedules which are used to select when specific messages are played from the real
time clock. The first seven schedules are for each of the seven days of the week. The last ÔweeklyÕ schedule is used for sounds you want to play at the same time seven days a week 10. Operating hours can be
set for the weekly schedule, or individually for each of the seven days of the week.
An example of the real time clockÕs use would be in a clock tower that uses a ÔWestminsterÕ chime.
This plays a slightly different chime on each quarter hour and tolls the full hours. The operating hours are
from 6:00 AM to 12:00 Midnight. Every day of the week, a ÔspecialÕ chime sounds each day at noon,
with other ÔspecialsÕ scattered throughout the day. On Mondays through Fridays, a ÔspecialÕ plays at 5:00
when the last work shift of the day ends.
To support ÔregulatorÕ style clocks, the AB/DR-3000s can be configured to pulse the Status Outputs
once per second, minute, hour, day or year. Regulator clocks typically use a single pulse every minute
to advance the minute hand, with a special pulse once each twenty-four hours to synchronize all the
clocks.
The clock can be set through the serial port or the front panel of the AB/DR-3000. Configuring the
schedules must be done through the AB/DR-3000Õs serial port using any computer or terminal.
When the clock is set, the AB/DR-3000 gives you the option of automatically adjusting for Daylight
Savings Time. If this option is used, then the clock will automatically ÔSpring forwardÕ on the first Sunday of
each April, and ÔFall backÕ on the last Sunday of each October. When the time is displayed on the Main
Menu of the AB/DR-3000, a ÔDSTÕ will appear before the time to indicate that it is currently in Daylight
Savings Time.
RS-422 SERIAL PORT:
The RS-422 Serial Port is the main method of communicating with the AB/DR-3000s. It is used for
doing virtually all the AB/DR-3000's configuration, and can be used for triggering and making dynamic
adjustments. Full details on the care and feeding of the RS-422 Serial Port can be found in the section of
the manual on Serial Port Commands.
Any standard computer can be used to talk to the AB/DR-3000s through its serial port. Modern computers, like AppleÕs Macintosh computers come with RS-422 compatible ports already built in. Older computers, like all IBM compatibles, have RS-232 serial ports on them. These can be used to communicate
with only a few AB/DR-3000s at a time with only a simple adapter cable. If you need to talk to several
AB/DR-3000s simultaneously, or over a distance of more than a few feet, you will need to add a RS-232
to RS-422 converter to your serial port.
The DR-3000 Serial Ports are usually connected with other Digital Audio Repeaters and Animation
Systems in a multi-drop network. Connections to other DR-3000s within the same card cage are made
through the card cageÕs backplane. Adjacent card cages can be interconnected through the fifty position Digital Audio Bus connector, or they can be run independently. Although they can be used on a serial network, AB-3000s tend to be used in stand-alone applications where they are typically the only device on their own very small network.
Commands are directed to a specific AB/DR-3000 or other piece of equipment located on the network by using the deviceÕs address. This is the one setting that must be made before a AB/DR-3000 is accessed as an upstanding member of the multiple drop serial port community. This will usually require
powering up the card to be addressed by itself so that its address can be changed. When any AB/DR3000 is powered up, it will display its current address setting for a few seconds on it front panel display.
When operating with the Intelligent Public Address System, the MA-100 PA Master acts as a ÔbridgeÕ
between any external computer or terminal and the rest of the system. All serial port commands are sent
through the MA-100, which also uses its serial connection to all the AB/DR-3000s for all of the public address commands.
FRONT PANEL ADJUSTMENTS AND INDICATORS:
Most of the minor adjustments which can be made to the AB/DR-3000 can be set through the front
panel on each unit. At your option, any or all of these adjustments can be enabled or disabled on the

All of these setting are adjusted by pressing the ÔSelectÕ button on the front of the AB/DR-3000. Any
setting that is not available to you (because it has been configured with a ÔfixedÕ setting or it is being
controlled from another source) will be displayed, but canÕt be changed. You can see any externally
controlled variable change as its control source alters it.
Values that can be adjusted are indicated by the flashing digits that show their current level. Once
the desired function number is displayed on the upper display, you can use the ÔupÕ and ÔdownÕ buttons
to adjust the setting as needed. Holding either of these buttons down for a moment will cause the numbers to automatically increment/decrement. When you are happy with the selection, pressing the
ÔSelectÕ Button until it is cleared stores the new settings permanently in the AB/DR-3000Õs nonvolatile
memory 13. The time will only be written to the Real Time Clock chip if you have made any changes in
the clock settings.
When not being used to configure one of the AB/DR-3000Õs functions, the front panel will display a
variety of status indications. First and foremost among these is the AB/DR-3000Õs ÔheartbeatÕ. This appears
in the lower right decimal point of the seven segment ÔSelectÕ display. If the AB/DR-3000 is alive, then this
LED should be flashing at a steady rate. The same output is attached to an integrated circuit called a
Ôdead man timerÕ. If the heartbeat ever stays off for more than about a second, the dead man will reset
and restart the AB/DR-3000.
The decimal points of the other two displays show the state of the two status outputs. These are typically configured to turn ON as the left or right repeaters are playing. They can also be told to turn on,
off, or pulse at specific points as spiels are played, or at intervals controlled by the real time clock.
The number of the most recently started spiel is displayed on the front of each AB/DR-3000. This is
shown as a two digit decimal number (hexadecimal numbers are used if more than 99 spiels are loaded
on the repeater) on the two digit seven segment display.
The two modulation LEDs on the front of the AB/DR-3000 will flash along with the sound as it plays.
There is one command which can be made only from the front panel. It is used to set the card back
to itÕs default configuration. This should rarely be needed. It is invoked by holding both the up and down
buttons as the repeater is powered up.

DIGITALINPUTS:
Each AB/DR-3000 has eight optically isolated inputs along with one manual start button on its front
panel. The manual start button is generally used for maintenance and testing purposes. The eight optically isolated inputs are Ôswitch closure inputsÕ normally used to trigger the AB/DR-3000.
The eight optically isolated inputs are arranged in the same 1/4 J6 standard pinout used in all of
Gilderfluke & CompanyÕs Animation Control Systems. The AB/DR-3000 checks both the rising (switch closure) and falling (switch opening) edges of each input. This allows you to configure a AB/DR-3000 to do
one action on one edge of a switch opening or closing, and then take a different action on the opposite edge. An example of this feature would be if you told the AB/DR-3000 to start looping on finding a
closure on one of the inputs, and then stop when the same input is opened again. The manual start button and 1/4 J6 inputs can be configured to tell the AB/DR-3000 to do any of the following things:
1) MUTE AUDIO: This sets the left, right or both channels immediately to their minimum output
level.
2) HALF MUTE AUDIO: This sets the left, right or both channels immediately to the half muted level
you have selected.
3) UN-MUTE AUDIO: This sets the left, right or both channels immediately to the normal output
levels you have selected.
4) FADE IN: This ramps the left, right or both channels to the normal level you have selected. The
length of the fade ins can be selected from .1 to 9.9 seconds.
5) FADE OUT: This ramps the left, right or both channels to the muted level. The length of the
fade outs can be selected from .1 to 9.9 seconds.
6) STOP REPEATER IMMEDIATELY: This immediately stops the left, right or both channels.
7) STOP REPEATER AT END OF CURRENT SPIEL: This stops the left, right or both channels at the end
of the current iteration of a loop.
8) START TRACK: This immediately starts the left, right or both channels. If no request for a specific
spiel has been received, then whatever spiel is next in line will be played.
Modifiers which can be used with the START TRACK command are:
a) LOOPING: When used with a START TRACK or START GROUP command, the spiel will con-
tinue to repeat. It can be stopped by either a STOP IMMEDIATELY or STOP AT END com-
mand is received. If the delay has been set on the repeaterÕs main menu, then this time
will be inserted between each iteration of the loop. The range of delay is from .1 to
999.9 seconds. This can be set independently for the left and right outputs if you are
using the repeater with mono spiels.
b) DELAYED START: When this modifier is set it will tell the repeater to wait for the amount of
time specified on the main menu before it actually starts playing. The range of delay is
from .1 to 999.9 seconds, and can be set independently for the left and right outputs if
you are using the repeater with mono spiels.
c) START GROUP: When the Group Start modifier is set, the Start command works just like
normal, except that it is relayed down the Digital Audio Bus. Any card that is assigned to
the requested group will be started within 44,100 of a second of all the others. This is
how perfect sync is achieved in bin loop applications. Delayed Start and Looping modifiers can be used normally. All of the repeaters that are assigned to the same Group will
follow whatever this repeater is told to do.
9) REQUEST A SPECIFIC SPIEL: Any one bit can be used to select a specific spiel, or a group of
bits can be used to make up a binary address. The latter can be used to select a number of
different spiels using only a few inputs. The same bit(s) that are used to request a spiel can also
be used to perform any of the above input commands at the same time as the request is
made. This means that a separate command is not needed to start the repeater after a request is made. The request alone can also start the requested spiel playing.
There are several options that you can select for early start commands. These are start commands
that come while the AB/DR-3000 is still playing the last spiel. You can tell the AB/DR-3000 to:
9
GILDERFLUKE & CO. ¥ 205 SOUTH FLOWER ST. ¥ BURBANK, CALIF. 91502-2102 ¥ 818/840-9484 ¥ FAX818/840-9485
1) Ignore early starts.
2) Jump Forward: Go immediately to the beginning of the next spiel.
3) Store: Ignore the early start for now, but save and do it as soon as the current spiel is done.
This can save requests approximately ten deep before overflowing.
When a AB/DR-3000 is first turned on, it checks the conditions of all the inputs, inverts them, and
then uses these to make the first checks of the inputs. What this allows you to do is to set any command
to happen when the AB/DR-3000 is first turned on. The most common example of this featureÕs use is
when you need the AB/DR-3000 to start looping as soon as power is applied. All you need to do is set
any one input to START and LOOP on the falling edge and the AB/DR-3000 will start playing as soon as
power is applied. This will work as long as there isnÕt a real input coming in on the input you have selected for this function.
STATUS OUTPUTS:
Each AB/DR-3000 has two optically isolated status outputs. These are the open collector outputs of a
pair of darlington output optoisolators. They can be used for driving LEDs, solid state relays, and similar
low-current loads directly. Any heavier loads will require a relay.
These outputs can be configured to:
1) Activate when the right channel of the AB/DR-3000 is playing a spiel.
2) Activate when the left channel of the AB/DR-3000 is playing a spiel.
3) Pulse momentarily, turn on or turn off at a specific time during a spiel.
4) Pulse once per second, minute, hour or every twenty-four hours. This option is only available
when the real time clock option has been installed.
ANALOG INPUTS:
Each AB/DR-3000 has eight 0-10 volt analog inputs which can be used for adjusting a variety of volume and mix functions dynamically. On the DR-3000s, the eight inputs are bused between all the DR3000s through the card cage and brought out to a standard 1/2 J6/A connector. This allows up to eight
different analog signals to be sent to all the DR-3000s in a card cage.
On AB-3000 AudioBricks, there are only two of the eight analog inputs which are brought out to the
screw terminals on the outside of the case. The other six inputs are still available inside the case if you
need them.
The input impedance on these inputs is 10 Kohms, and they are protected against slightly overvoltage signals. The input resistors can be modified if a different control voltage range is required.
DMX-512 INPUT:
The DMX-512 standard was developed by the United States Institute for Theatrical Technology (USITT)
for a high speed (250 KBaud asynchronous) serial link. Although it was originally designed for controlling
light dimmers, it is now supported by hundreds of suppliers throughout the world for controlling all kinds
of theatrical equipment. Along with the direct analog or digital outputs, all PC¥MACs systems come with
a DMX-512 compatible output. The Analog Smart Brick can be used to generate a DMX-512 output from
a Smart Brick System.
You can set AB/DR-3000s to listen to any four DMX-512 addresses between 0 and 255 (00h to FFh).
One DMX-512 channel can be set to mirror the eight optically isolated trigger inputs. In that way, any
function you could trigger with the external inputs can also be triggered through the DMX-512. Any
channels that arenÕt being used for triggering can be used to adjust the volumes and mixes on the
AB/DR-3000s.
The DMX-512 input to a Repeater is disabled whenever SMPTE IN, SMPTE OUT or IR MODE are being
used. They all use the same serial ports and timers.
Even though the DMX-512 standard calls for 512 channels of data, the DMX transmission from a
PC¥MACs Animation Control System is limited to 256 eight bit wide channels. Addresses above the 256th
are used in PC¥MACs for transmitting a checksum. The AB/DR-3000 can use this to verify that the data
received from PC¥MACs has no transmission errors in it. If you address a light dimmer or other DMX-512
device to addresses 256 or 257, you will see this verification data displayed as a flickering pattern. This

feature can be turned off for running Gilderfluke & Co. equipment from systems that canÕt generate a
checksum.
AUDIO OUTPUTS:
The normal audio output from the AB/DR-3000 is a balanced +10 dB line level. The output driver is a
SSM-2142 transformerless output driver. This chip is compensated for driving standard 600 ohm balanced audio lines. If running to a single ended amplifier, you will need to ground the unused output. If
you donÕt, the output will be excessively noisy.
Several digital output options are available with the AB/DR-3000 series of repeaters. They allow audio
data to be sent to your amplifiers in a completely digital form for absolutely no noise and distortion. All of
these options require a digital output driver chip be installed on the AB/DR-3000, and a special conditioning card on the back of the card cage 14. These conditioning cards provide the proper signal levels
and connectors for running the signals to your amplifiers in one of three industry-standard formats. These
are:
a) AES/EBU: Three position XLR connector for running balanced digital signals to your amplifier.
b) SPDIF: RCA connector for running single ended digital signals to your amplifier.
c) OPTICAL: Fiber optic connector for running optical digital signals to your amplifier. Surprisingly,
this is the most economical digital link to use.
When running digital output signals from the AB/DR-3000s, the normal analog outputs remain active
and usable.
SMPTE IN AND OUT:
SMPTE (pronounced Òsimp-TÓ) is a time code which was developed by the Society of Motion Picture
and Television Electronics (SMPTE) for use in audio, film, and television production. It is normally recorded
on a spare audio track on the medium being used (audio tape, video tape, or film), and then used to
synchronize various pieces of compatible equipment together. As an industry standard, virtually every
audio, video or film studio in the world will have the equipment to support a SMPTE time code track.
SMPTE is usually recorded at thirty frames per second. Twenty-five frames per second is used in
Europe and places where this is the normal television frequency. Twenty-four frames per second is occasionally used in film production. What this means is that 30 (or 25 or 24) times each second a number is
recorded on the tape or film. This number represents the hours, seconds, minutes and frame
(00:00:00.00) for this particular little stretch of film or tape. Since each little stretch is represented by a
unique number, SMPTE is known as an ÔabsoluteÕ time code. No matter where the tape is, the AB/DR3000 will instantly evaluate the numbers it gets from the SMPTE time code to figure out where it is.
If enabled, AB/DR-3000s generate SMPTE time code whenever their LEFT channel output is playing.
This is whenever a stereo sample is being played back, but only when the Left channel is playing if mono
ROMs are installed.
When generating SMPTE time code, the AB/DR-3000 will start at zero minutes, frames and seconds
(00:00.00). The hour number generated is taken from the spiel number being played. For spiels numbered one to ninty-nine, they are displayed as-is. If there are more than ninty-nine spiels on a repeater,
they are displayed using the hexadecimal numbering system.
The only frame rate the AB/DR-3000s will generate is 30 FPS, non drop frame 15. Note that the actual
frame rate generated by the DR-3000 is slightly off from an actual 30 Hz frequency. Over the course of
a 10 minute spiel, it will get off by about one second from the actual time. Additional error can also be
generated by drift between the crystal that is used for audio reproduction and the one that is used by
the microcontroller. Any equipment which is synchronized to the AB/DR-3000 system should never so
small an error.
One of the advantages of programming a show to a SMPTE time code is that it is easy to start and
stop a tape or just back up a little. The disadvantage with a repeater is that they always insist on starting
at the beginning of a spiel. We recommend that before you program a show you generate a ÔscratchÕ
14
This plugs right into the AB-3000.
15
ÔDrop FrameÕ time code literally ÔdropsÕ a frame every few seconds.
11
GILDERFLUKE & CO. ¥ 205 SOUTH FLOWER ST. ¥ BURBANK, CALIF. 91502-2102 ¥ 818/840-9484 ¥ FAX818/840-9485
tape for use during programming 16. This is done by using the repeater as both the audio source and
SMPTE generator. You can then program the show normally with absolute assurance that the final audio
and time code will be perfectly in sync.
The SMPTE time code input on each AB/DR-3000 can listen to a SMPTE time code signal and trigger
spiels on the left or right side of the repeater. Once triggered, the repeater will NOT follow variations in
the SMPTE time code input. The table of SMPTE trigger points holds up to forty-eight different entries.
Triggering resolution is down to a single frame, but only one spiel can be triggered during a single second. The AB/DR-3000 needs to have been listening to time code long enough to receive the beginning
of the second before the trigger. This means that if the time code is starting at 00:00:00.01, that no spiel
can be triggered before 00:00:02.00. The AB/DR-3000s should accept SMPTE time code within 25% of
30 Hz which is recorded with 24, 25, 30 or 29.97 Frames Per Second. The time code can be either Drop
or non-Drop frame. The only thing you have to do is not to ask the AB/DR-3000 to trigger on a frame
which doesnÕt exist in the incoming frame rate. i.e.: If you are using SMPTE at 25 FPS, donÕt try to trigger
sounds on the 26th frame.
INTELLIGENT PUBLIC ADDRESS SYSTEM:
The Intelligent Public Address System is used where a powerful and flexible zoned Public Address
System is needed. It can be used with our DR-3000 and DR-4000 Digital Audio Repeater cards or in
stand alone installations. Complete information on the Intelligent Public Address System can be found in
its manual.
The Intelligent Public Address System features include:
¥ Up to 255 PA zones are available. Sixteen cross-zone announcements can be made at one
time, along with any number of local PA zone requests. These latter take place when any PA
station requests itÕs local PA output.
¥ Supports up to 256 PA stations. These are available in:
a) One Button PA Stations use the microphoneÕs Push To Talk (PTT) button to select any one
of the PA zones.
b) The Four Button PA stations can select any of four different PA zones, plus one more with
the microphoneÕs PTT button. You can tell the buttons on these stations to latch the zone
requested, only momentarily select the zone, or latch it until the next time the PTT button
is released. Any of the four buttons can also be configured to raise or lower the volume
or mute and unmute an area.
c) The Smart PA stations can be set up to access all the features in the entire audio system.
These include any Digital Audio Repeaters, Animation Control Systems, and volume control zones that happen to be attached to it. They are available with backlit LCD displays
on them. Their pushbuttons are normally located on the microphone itself, or any DTMF
keypad can be used.
d) Phantom PA Stations are used to tie the output from Digital Audio Repeater to the PA sys-
tem for automated announcements. When the Repeater is triggered, it will select a PA
zone and feed the audio output from the repeater to the selected zone.
¥ All setup is done through easy to use menus using any PC or terminal. Configuration includes
selecting which zones any PA station button will select, and the normal, half-muted, and PA
announcement volumes for the local PA outputs. A key lock and battery protects the configuration data from unauthorized access and power failure.
¥ Separate printer and terminal outputs can give a running record of all PA system activity.
¥ PA Master controls up to eight volume zones, or any other 0 to 10 VDC controlled device
(lights, screens, etc.).
¥ Eight PA stations per Interface Panel. Stations are transformer and opto isolated from the rest of
the system.
¥ Wiring to all PA stations is by standard 8 conductor modular telephone line. Power for the sta-
16
The tape can be a cassette or any other suitable format.

tions is provided by the PA interface.
¥ Each DR-3000 or DR-4000 Repeater added to the Intelligent PA system adds another possible
PA output to it.
¥ The PA system can act as a bridge to run animation systems, Digital Audio Repeaters, etc.
from PA stations.
The PA system consists of one PA Master, one PA Interface Panel for each eight PA stations (the first
one of these is part of the PA Master), and the PA Stations themselves. These are available in four different styles:
Each PA Interface Panel has connections for eight PA stations, eight balanced ÔlocalÕ PA outputs, and
one (optionally eight) balanced Back Ground Music (BGM) inputs. The BGM is normally fed to the eight
local PA outputs. When one of these responds to a PA zone request, the PA announcement is fed to it as
the BGM is half-muted. Each local PA output can respond to four different prioritized PA zone requests.

As shown by the darkened audio path in the previous illustration, when a user at any PA station requests a PA ZONE, an audio path is opened to any of the Local PA Outputs and DR-3000s in the system
that have been configured to respond to requests for that PA ZONE (in this example there are three DR3000s or DR-4000s and four Local PA Outputs responding). The normal audio on those outputs is
dropped to the half muted level (this level is adjustable on each output) while the audio from the PA station is routed to the outputs (the volume of the announcement is also adjustable on each output). The
rest of the audio system and the Repeaters on the affected DR-3000s continue to operate as usual. Up
to sixteen such PA announcements can go on at the same time.

Eight LOCAL PA OUTPUTS are available from each MA-100 or MA-200 card. Each of these outputs normally carries whatever audio is being fed into the ÔBack Ground Music (BGM) inputÕ on the back of the
unit. When a request for a PA zone comes in, the BGM level on that LOCAL PA OUTPUT is dropped to a
half-muted level and the PA audio is mixed into it. All audio levels and settings for the LOCAL PA OUTPUTS
are adjusted through the software on the MA-100 PA Master. Each LOCAL PA OUTPUT can be told to respond to up to four different PA zone requests. If the PA STATION requesting the LOCAL PA OUTPUT has
the same ÔnumberÕ as the output being requested, a special ÔLOCAL PA MODE' can be used as shown
above. This bypasses the sixteen trunk lines that normally carry the PA audio feeds to allow up to 256
such PA announcements to go on at the same time.
There are 256 possible PA ZONES. Any DR-3000 can be configured to respond to up to sixteen different PA ZONE requests (eight per side). Any number of DR-3000s can be configured to respond to any individual PA ZONE request. This allows a PA ZONE to be assigned as a global PA ZONE by simply telling all
the DR-3000s in the system to respond to it. The priority of PA requests is set by the order in which they
are entered when configuring the DR-3000.
DUMB PA STATIONS are available with either four buttons (plus the microphone button) or one button
(just the microphone button). Any of the buttons can be configured to access any PA zone in the system. The buttons on the front of the four button stations can be configured as push-to-talk buttons, to
latch the last requested zone, or auto-release the last zone latched when the microphone button is released.
For automated PA announcements, a phantom PA station is used. It is like any other PA STATION except that it has no buttons or microphone on it. The audio and status outputs from a AB/DR-3000 is attached to the phantom PA station. When the Repeater is started, the status output triggers the phantom
PA station to request a PA ZONE and then feeds its audio into it. The audio will then be routed to the appropriate audio outputs through the PA system just like any other announcement. Different spiels can

also be requested and PA Zones accessed through the serial port if needed.
SMART PA STATIONS are available with up to eighteen buttons on their microphones. Any button can
be configured to request any other intercom station, mute or half-mute zone, send commands to one
or more AB/DR-3000s, or ramp the volume of any volume control zone up or down. For those PA STATIONS which need access to more features than this number of buttons would allow, a numeric-style
entry is used to give them access to any features which you have enabled.

a) DMX-512: Three position screw terminal block. These signals are bused to any other intercon-
nected card cages through the DIGITAL AUDIO BUS connector (if it is used), so the other bused
cages donÕt need their own DMX-512 connections. This connection is used to feed the USITT
standard DMX-512 serial data into the DR-3000 and DR-4000s mounted in this cage. This can
be used for adjusting volumes and triggering the DR-3000 and DR-4000s.
b) RS-422: Six position RJ-11 (modular telephone style connector jack). These signals are bused
to any other interconnected card cages through the DIGITAL AUDIO BUS connector (if it is
used). The other bused cages then donÕt need their own RS-422 connections. This input is
used to connect the DR-3000 and DR-4000s installed in this cage to a computer or terminal
for configuration or remote control. Facing the end of the cable with the release latch upwards, its pin out is as follows:

A CC-3004 has four for these connectors on it, while the CC-3016 has sixteen. This input
connector uses the standard Ô1/4 J6Õ pinout used in all the Animation Control Systems manufactured by Gilderfluke & Company. All eight inputs are optically isolated from the AB/DR3000, and so an external source of power is needed to run this input 17. The current draw is
less than sixteen ma. per input, so a small wall mounted DC power supply will be sufficient to
drive it. The PS-200 Power Supplies have a 24 VDC output on them that can be used to power
17
The AB-3000 has a jumper option of supplying power to the 1/4 J6 input from the AB-3000Õs power
supply. If this option is used, then simple switch closures can be used on these inputs.

these inputs. Be aware that this supply is not isolated from the others. This defeats the opto isolation and there is a possibility of AB/DR-3000s getting ÔzappedÕ through this connection.
The DR-3000 can only be attached as shown above for ÔExternal PowerÕ. The AB-3000 has
the option of running from ÔInternal PowerÕ. This allows simple Ôswitch closuresÕ to be used with
the AB-3000. As with using the 24 VDC output from the PS-200, this reduces the protection afforded the AB-3000 by the optoisolator inputs.
d) 1/2 J6/A VCA Inputs: Twenty position enclosed header compatible with IDS-20 connectors.
This connector is used to run up to eight 0 to 10 VDC control signals to the DR-3000 and DR4000s installed in this card cage. These can be used to remotely control the volumes and
other analog adjustments on the DR-3000s. The impedance of each input is 20 Kohms. The
pinout is as follows:

On the AB-3000 AudioBricks, only two of the eight analog inputs are brought out to screw
terminals on the outside of the case. The remaining six inputs are available inside the case if
you need to use them.
e) Power Supply: Four position screw terminals on revision 1.0 backplanes, six positions on all
later ones. This connector is wired in parallel with the AUX. POWER connector. The screw termi-
nal is used on CC-3016 cad cages for attaching it to a PS-200 power supply. The AUX. POWER
connector is used on CC-3004 card cages. The pinouts for the screw terminals are
silkscreened on the backplane.
The two ÔsenseÕ terminals are used to feed voltage information back to the PS-200 power
supplies so that the five volt regulation is more stable. On the earlier (1.0 revision) CC-3016
backplanes, the sense inputs to the PS-200 should be connected to the AUX. POWER connec-
tor.
f) Aux. Power: Five position 180¡ DIN connector 18. This connector is wired in parallel with the
POWER SUPPLY screw terminal. The screw terminal is used on CC-3016 cad cages for attach-
ing it to a PS-200 power supply. The AUX. POWER connector is used on CC-3004 card cages.
The pinouts for the screw terminals are silkscreened on the backplane. The pinout for the ALT.
POWER connector is as follows:

Use extreme caution when making discrete wire connections to the AUX. Power, as five pin 180¡
DIN connectors are numbered 3, 5, 2, 4, 1 as you face the socket on the back of the card cage.

This is the only power supply connection on the AB-3000 AudioBrick.
g) Audio Outputs: Twenty-five position female DB-25 connector. This is used for the balanced
audio outputs from the DR-3000 and DR-4000s installed in the card cage. CC-3004 Card
cages have one of these connectors on them. CC-3016 Card cages have four of these connections on them. Each DR-3000 or DR-4000 has two balanced audio outputs on it. The

The balanced line drivers used on the DR-3000 and DR-4000s are a SSM-2142. This chip
provides a high quality balanced output that is compensated for 600 ohm lines. If operating
in single ended mode, the unused outputs must be tied to their respective ground lines. If
you donÕt, the output will be excessively noisy.
i) Audio Inputs & AES/EBU Inputs: Fifteen position male DB-15 connector. This is used to feed
analog and digital audio signals into a DR-4000 installed in slot 0 of the card cage. Additional
connectors may be wired to any other slots in the card cage if more than a single DR-4000 is
to be used. The pinout is as follows:

h) SMPTE Out/In, Status Out, AES/EBU Out: Nine position male DE-09 connector. There is one of
these connectors for each slot in the card cage. A CC-3004 has four for these connectors on
it, while the CC-3016 has sixteen. As can be seen by the functions carried on this connector,
it is used for all of the left over inputs and outputs on each of the DR-3000 and DR-4000s:

1 & 6 SMPTE Out: If enabled, The AB/DR-3000 can generate SMPTE time code as they play.
This is a line level output which can be attached to the inputs of most animation and
audio systems.
2 & 7 SMPTE In: This is the line level input for SMPTE time code to each AB/DR-3000.
3, 8, & 5 Status Out: Status output #2 is not available on revision 1.0 card cages. These are
two optically isolated open collector outputs. They can be configured to go active when
a repeater is playing sound, at specific points while the repeater is playing, or, if operating from the Real Time Clock, once per second, minute, hour or every 24 hours. This latter mode is used to run ÔregulatorÕ style clock faces that require a ÔpulseÕ every minute,
and another each day to resynchronize all the attached clocks.

output is limited to driving low current loads like solid state relays, optoisolators, logic
level inputs and LEDs. When attaching to a logic input, just use pullup resistors (4.7 Kohm
typically) to the logic Vcc, and pick up to output at the DE-09 output pin. For the base
resistor in series with a LED, use a 1 K at 5 volts, 2.2 K at 12 volts, and a 4.7 K at 24 volts.
These will limit the current to about 5 ma. through the optoisolators. Solid state relays
need no current limiting resistors, as they are internally current limited to the proper levels.
4 & 9 AES/EBU: This is the direct output from the CS8401 AES/EBU driver chip. Although this
chip outputs a differential signal, to fit the specifications for SPDIF (single ended output),
AES/EBU (balanced output) or Optical (fiber optic), it needs to be fed through a pulse
transformer and a few resistors first. A Small PC board with these parts and the appropriate connector (along with the CS8401 chip) are available from Gilderfluke & Company
as part numbers ÔSPDIF-OUTÕ, ÔAES/EBU-OUTÕ, and ÔOPTO-OUTÕ respectively.
j) Digital Audio Bus:21Fifty position enclosed header compatible with IDS-50 connectors. This
connector can be used to bus several signals between interconnected card cages. If used,
these signals are:
1) Digital Audio Bus: This includes the clock and bus master signals, so only one card
within any set of interconnected card cages can be used as the bus master.
2) DMX-512: This eliminates the need to connect the DMX-512 input to each of the inter-
connected card cages.
3) RS-422: As with the DMX-512 above, this signal is bused to all other interconnected card
cages to eliminate the need to connect the RS-422 to each one individually.
This connection is not available on the AB-3000 AudioBrick.
k) AB-3000 Audio Outputs: The AB-3000 AudioBricks use two 1/4Ó phone jacks for their audio out-
puts. Electrically, these are identical to the outputs of the DR-3000s. As shown on the AB-3000
case silkscreening, if you are using balanced input amplifiers, you can use ÔstereoÕ plugs to
connect to your amplifiers. When using single ended input amplifiers, use a ÔmonoÕ style plug
and this will ground out the unused output as needed.
