EXTRACTOR TOOLS

Module Removal Tools

Your Wheatstone D-8000 audio console is equipped with two
"module extractor tools" which are mounted underneath the
console armrest, to the far right (just above and to the left of
the righthand mainframe headphone jack).

Main module faceplates are held into the console mainframe by two
mounting screws (top and bottom). When removed the screws leave
specially threaded holes that accept the two extractor tools.

To remove a module faceplate from the mainframe:

Remove the front top and bottom mounting screws. Remove the extractor
tools from underneath the armrest, and screw each tool into a module
faceplate mounting hole. Use only four or five turns (do not over-insert; you
may damage the threaded mainframe hole underneath). Using the extractor
tools as handles, pull the module straight up out of the mainframe.

Installation and Power

Countertop Mounting

The D-8000 digital audio console is designed for countertop drop­in mounting. Console placement should avoid proximity to any elec­tromagnetic fields, such as large power transformers, motors, and
fluorescent lighting fixtures. The required cut-out width is determined
by the actual number of mainframe positions. The formula is:

(console positions X 1.508”) + 1.375” = cut-out width

Example: (32 x 1.508) = 48.256, and 48.256 + 1.375 = 49.631.
Rounding this off we arrive at 49 5/8” for a cut-out width.

Cut-out front-to-back dimension is always 18 5/8”. The front of the
console will extend approximately one inch forward of the cut-out. The
console’s wooden side pieces will extend about 7/8” on either side of
the cut-out width.

Clearances

Note the two module extractor tools (black thumbwheel screws)
mounted in the front surface of console’s lower mainframe pan (just
above and to the left of the righthand headphone jack). These must be
removed before lowering the console into its cutout!

Once in place the console mainframe pan will extend approxi­mately 5 1/2 inches below the countertop surface. Note the hinged
meterbridge will require 8 1/2” above the countertop surface to open
freely. When fully open the meterbridge will extend 5 1/2” behind the
rear line of the cut-out. When closed, the meterbridge will extend
2 1/2” behind this rear cut-out line and 6 1/4” above the countertop
surface.

Do not connect the D-8000 console to its power supply (and do not
connect the power supply to the AC power line) until instructed to do
so.

System Ground

The first step is to ground the console.

Note that as supplied from the factory, console rackmount power
supply common, audio ground, and the D-8000 mainframe are con­nected together at the console, but are NOT connected to electrical
ground and the chassis of the power supply. Safety requirements
dictate that a positive connection from the console mainframe to

GROUNDING SCHEME

electrical ground be made in the completed installation. Use one of the
grounding lugs on the bottom of the mainframe to establish your
system ground. The grounding lug terminal strip may be found at the
rear of the console, along the bottom edge of the mainframe pan directly
under the rightmost mainframe slots (to the lower left if you are looking
at the rear of the console).

The system ground serves two important purposes:

(1) It provides a zero signal reference point for the entire audio system;
(2) It assures safety from electrical shock.

Tie the console ground lug
terminal strip to the system
earth ground. Tie every piece
of equipment in the entire
audio system to the console
ground lug terminal strip.

There exist two terms that one encounters in a discussion of ground:

(A) EARTH GROUND, which is usually a heavy copper rod driven into the
soil adjacent to the building (around 6 feet down) or a connection to the copper
water pipes leading into the building. Either is acceptable (unless, of course,
the water pipe is made of plastic).

(B) THE POWER COMPANY EARTH CONDUCTOR that enters the
building at the power line breaker box; this conductor should be (and is often
by code) tied to the above-mentioned earth ground at one point. This point is
the SYSTEM EARTH GROUND.

D-8000 / Jan 2003

page 1 – 3

INSTALLATION and POWER

TIE THE CONSOLE GROUND LUG TERMINAL STRIP TO THE
SYSTEM EARTH GROUND. TIE EVERY PIECE OF EQUIPMENT IN
THE ENTIRE AUDIO SYSTEM TO THE CONSOLE GROUND LUG
TERMINAL STRIP. If the system earth ground point is inaccessible, tie
the console ground terminal strip to the power company earth conductor
at the main breaker box (see drawing "Typical Grounding Scheme" on
previous page).

Each piece of equipment should be connected by its own ground wire
(usually the round third pin on the AC cord). This means that every AC
outlet must have a separate conductor run to the console ground lug
terminal strip; the outlets cannot be daisy-chained as is normally encoun­tered in commercial and residential AC systems. Any equipment not
supplied with 3-wire AC cables must have individual ground wires (16
gauge or larger) connected to their chassis grounds and then run to the
console ground lug terminal strip.

Further Grounding Details

Check all equipment to be absolutely certain that each unit is power
transformer isolated from the AC mains to prevent safety hazards.

It is assumed that in each piece of audio equipment the audio ground
and the chassis are tied together at some point. Any piece of equipment
lacking a grounded chassis is likely to be prone to interference problems.

Locate all unbalanced audio equipment in the same rack if possible, to
minimize chassis ground potential differences. It may also be helpful to
insulate each piece of unbalanced equipment from its mounting rails in the
rack by means of nylon 10-32 screws and insulating washers between rails
and faceplates.

Once the system is properly grounded, proceed with the console
power supply installation and connection (next section).

Power Supplies

The D-8000 console is powered by an SPS-180 or SPS-400 power
supply installed in a Wheatstone Model PSR rackmount unit. Each PSR
houses up to four SPS-180 or up to two SPS-400 power supply units.
Mount the power supply in a standard 19” equipment rack, keeping in
mind that adequate ventilation is necessary to prevent heat build-up within
the rack.

Note the power supply (supplies) should be mounted in an equipment
rack within fifteen feet of the console (but no closer than 3 feet). Avoid
locating any high gain equipment (such as phono preamps, tape recorders,
etc.) too near the rackmount supplies, to avoid magnetic interference into
that equipment.

This power supply contains high voltage circuits that are hazardous and
potentially harmful. Under no circumstances should the metal cover be
removed! If you have a problem with the power supply, the unit must be
returned to Wheatstone Corporation for repair.

D-8000 / Jan 2003

D-8000 / Oct 2003

If failsafe redundant sup­plies have been ordered,
you will be installing two
SPS-180 or SPS-400
units.

INSTALLATION and POWER

t

Once the supply is rackmounted, it should be connected to the console
using the factory supplied cable. The console’s two power supply connec­tors are located at the rear of the console, one at each end of the meterbridge
bottom pan. If you are using two supplies (failsafe option) one supply will
connect to each console connector; otherwise only one connector will be
used (it does not matter which one). Note that the power supply cable’s 10­pin female connector has to be rotated until its locating pins match the male
connectors on the console. Do not force a connector on; it attaches easily
when properly aligned. Connect the cable(s) first to the console, then to the
rear of the rackmount power supply.

INSTALLATION and POWER

Note each power supply is fitted with a 3-wire grounded AC cord
that should be plugged into a "clean" AC power source, that is, an AC
source that feeds only the control room audio gear. This source should
be a separate feed from those powering lighting, air-conditioning, or
any other non-audio machinery. The third pin ground wire of the AC
source should be tied to the central system ground point. Note that

while the AC power cord ground wire terminates at the power supply
chassis, it does NOT connect to the D-8000 console common; the
console itself must be grounded separately. (See previous section,
"System Ground".)

Failsafe Dual Redundant Supply

Wheatstone failsafe power supply systems use two SPS-180 or
SPS-400 power supplies for each piece of powered equipment. Though
either is capable of running a full load on its own, in failsafe operation
both units run in tandem: if one fails, the other takes over, assuring
uninterrupted operation.

In order for failsafe systems to perform as designed, always have
BOTH supplies powered up and connected to their associated equip­ment.

Energizing

Assuming the D-8000 console mainframe is properly placed and
grounded, and its PSR power supply correctly rackmounted and
connected to the console, you may now energize the PSR rackmount
power supply by plugging it into the AC mains. The console's VU
meters will illuminate and individual module switches will assume
factory default settings.

Note: To de-energize the console, unplug the rackmount power
supply’s AC cord from the AC mains. Never de-energize the console

by disconnecting the cable that connects the console and power
supply together.

The power feed recom­mended in the text is of­ten installed and referred
to in studios as an “iso­lated AC ground” outlet.
It is usually orange in
color.

Audio and Control Wiring

All audio and control I/O connections to the D-8000 console are made
through multipin DB-25 connectors located on the bottom of the console.

The Insulation Displacement Connector System

The I/O wiring interface system is based on insulation displacement
technology. A special AMP wiring tool is included with each console; it is
auto-indexing, and allows individual wire connections to be positively made
with a single squeeze of the tool's trigger. The trigger action is ratchet
controlled, and will not release until a full connection is made. Once released,
the multipin connector held in the tool's jaw automatically indexes to the next
connector pin. The technology is such that no stripping, soldering or tinning of

plated pins) and latching
hoods are supplied with each
console.

wire ends is required; all that is needed is for the wires destined for the
connector be snub cut and laid out in order (although tubing should be used on
bare drain wires). An empty DB-25 (or in the case of the optional LSR-500
rackmount line switcher, a DB-9) connector is inserted into the tool, indexed
to the first pin, and the wires are inserted one by one into the jaw and the trigger
squeezed. In this way a single multipin connector can be completely wired up
in a minute or two.

In the event of a wiring error, connector pins may easily be removed from
the shell with the wire still attached, and inserted into the correct position.
Observe the side of the connector, with the metal part down. You will see a row
of "Vees"—simply press the top of the vee together with a scribe or other sharp
instrument; this will unlock the pin from the shell, and it can be removed and
inserted into the correct position. Spread the vee apart to lock the pin in the new
position. It should never be necessary to discard a connector due to a wiring
error.

Note that mating hoods for each connector are also supplied with the
console. These have locking screws that hold the connectors securely to the
bottom of the console mainframe.

INSTALLATION and POWER

Connection Procedures

As supplied from the factory, the console requires no logic connections
to function. Therefore an orderly installation begins with the audio wiring.
Note this manual is organized by module type (inputs, outputs, monitor
modules, etc.); each chapter contains detailed wiring instructions for its
module type. Proceed through the manual, chapter by chapter, until all
modules have been wired to suit your particular installation requirements.
Once proper audio operation is verified, go back to each individual chapter
and proceed with control wiring.

Digital Audio Connections

CABLE - All AES/EBU input and output digital audio connections are
balanced and should be made using a high quality digital audio cable. Be
sure to select a digital audio cable with an integral drain wire of the same
wire gauge (AWG) as the twisted pair. Typical AES/EBU digital audio
cable has a very low characteristic capacitance per ft (pF/ft), and a nominal
impedance of 110Ω. High quality digital audio cable offers better signal
transmission performance versus typical analog audio cable, especially
over long cable runs. Check the cable manufactures data sheet to be sure
the cable you plan to use will work in your application.

CONNECTORS - All AES/EBU connections are made with the
supplied DB-25 male mating connectors. These crimp style connectors are
the insulation displacement type and will accept wire gauge 22 - 26AWG.

Analog Insert Points

The OUTPUT MODULES (OMD-8) have insert patch points in their
signal chains to allow outboard audio processing.

Normally these points are internally bridged at the factory (via PCB­mounted programming switches) prior to shipment. If you intend to use
outboard signal loops at these points, you must reprogram these switches.
See page 4-3 (output modules) for details.

Unbalanced Connections (analog audio)

ANALOG INPUTS — Wire to the console with typical shielded two
conductor cable (like Belden 9451), just as if you were connecting a
balanced source. At the unbalanced source machine’s output, connect the
black wire (“LO”) to the shield. If the machine has a -10 dBu output, don’t
hesitate to turn module input gain as high as is needed.

ANALOG OUTPUTS — D-8000 consoles use a balanced output
circuit which behaves exactly like the secondary of a high-quality trans­former, with no center tap—this output is both balanced and floating.
Either the “HI” or “LO” side of the output should be strapped to ground,
with the output taken from the other side. (Normally you’d strap “LO” to
ground, and take “HI” to feed your unbalanced equipment.)

Wiring Procedure - Double Connection to One Pin

ref: DB-25 male multi-pin connector

Most audio equipment machine interfaces (as well as Wheatstone consoles) use
subminiature D-type connectors. Sometimes the interfaces require making two connec­tions to a single DB pin. If the wiring has been set up using punchblocks, this is not a
problem; however, for situations where direct machine-to-console wiring is used, Wheat­stone recommends the following procedure:

1) Connect the first wire to the desired pin as you normally would.

2) Note connector pins may easily be removed from the DB-25 shell with the wire still
attached: Hold the connector with the metal part down and observe its side. You
will see a row of "Vees"—simply press the top of the selected vee together with a
scribe or other sharp instrument; this will unlock the pin from the shell, allowing
it to be removed.

3) With the pin removed, strip out a short section of insulation from the connected
wire and wrap and solder the second wire to the first as shown above.

4) A short piece of heatshrink tubing (pictured here before being slid into place)
completes the connection.

5) Re-insert the pin into the DB-25 shell, spreading the vee apart to lock it in place.

DIGITAL/ANALOG INPUT

Digital/Analog Input

Modules

(IN-8/INM-8/INDM-8)

Overview

The Digital/Analog modules are for stereo line input
signals. There are three different types of the module:
IN-8, INM-8 and INDM-8. Each module accepts both
+4dBu balanced analog input signals and digital (AES)
inputs. They have L/R front panel input gain trimpots for
analog input signal.

Each module accepts two stereo sources: A and B,
switched at the top of the module. The MODE SELEC­TION enables the module to operate in stereo, mono, left
only, or right only. The MODE button illuminates red
when set to STEREO, and is off when set to MONO
(L+R to both channels), LEFT to both channels, and
RIGHT to both channels. Being electronic, mode selec­tion is lossless and click-free. When in MONO mode
automatic gain compensation occurs to offset mono
summation.

Output switches assign the selected source signal to
any combination of the console’s four stereo outputs:
PGM (program), AUD (audition), AUX (auxiliary) and/
or UTL (utility). When the module is assigned to PGM
and turned ON, a red “Air” LED illuminates just above
the output assign switches. Utility output can be pro­grammed via VDip software to be pre-fader and pre on/
off for A and/or B sources.

The CUE switch can be enabled or disabled via VDip
software. When the CUE switch is enabled, it places the
module’s signal on the console’s stereo cue bus, where
it may be heard on the meterbridge mounted cue speak­ers and/or as an interrupt to the console operator’s
headphones and control room monitor speakers. The
various cue interrupt modes are programmed at the
console’s CRD-8 (Control Room) module via internal
PCB-mounted dipswitches (see page 5-3).

IN-8 INM-8 INDM-8

page 2 – 2

DIGITAL/ANALOG INPUT

The INM-8 and INDM-8 modules have an additional IFB option. This
option allows each input module to generate an individual mix-minus
output; thus each anchor, each announcer, each host, each guest can have
a dedicated mix-minus feed. An analog IFB out is always available, and
an AES IFB out can be enabled or disabled via VDip software. When the
MXM switch is pushed, the module’s signal will be sent to the mix-minus
bus. Each module with the IFB option will have a summed signal from
mix-minus bus except it own signal.

A momentary TB switch will sent the TB monitor signal to the IFB
output of the module.

On the IN-8, INM-8, and INDM-8 modules the SET switch links to the
SEND controls on the optional CPU-8S module (Chapter 8) to assign the
module’s audio to the SEND outputs. The INDM-8 module is also
equipped with DSP. On this module the SET key also initiates the attention
of the central control module (described in Chapter 14) in the meterbridge
for control of DSP functions. This allows the operator to adjust many audio
parameters for the module, including gain trim, EQ, ducking, and com­pressor-limiter characteristics. An illuminated green “DSP” LED indi­cates that some corrections were made for this input signal. .

INDM-8 modules with DSP have ten-segment level and gain-reduc­tion metering.

Level is set by a Penny & Giles long-throw fader. When the D-8000 is
under external serial control from an automation system, the Fader Null
LEDs show which direction the fader must move for manual override.

Channel ON (red) and OFF (orange) switches are at the bottom of the
module. In addition to being controlled remotely, these can also be
programmed (via VDip program) to perform a variety of functions,
activating control room and studio mutes, external tallies, and timer
restart. The OFF switch’s LED can be controlled by an external source
machine to act as a “ready” indicator.

All audio and control input and output signals are made via two multi­pin DB-25 connectors mounted in the bottom of the console’s mainframe,
directly underneath each individual module.

Internal Programming Options

There are no internal programming options on the IN-8, INM-8 and
INDM-8 modules.

VDip Programming Options

Mutes, timer restart, cue dropout, local/ready, tallies, talkback to
control room, superphone output assign, utility bus pre-fader, remote on/
off-constant vs. pulse, and remote start/stop-normal vs. EFS programming
are made via Virtual Dip Switch Software (see Chapter 9).

Hook-Ups

As stated before, all user wiring to and from INDM/INM/IN-8 modules
takes place at DB-25 multi-pin connectors mounted directly beneath each
module on the console mainframe’s bottom pan. There are two connectors
per module: the upper one (towards the console meterbridge) handles
audio inputs; the lower (near the console armrest) control signals. Pinout
drawings on pages 2-8, 2-9 and 2-10 show all wiring connections at a
glance.

To Turn the Module ON & OFF from a Remote Location

In the case of stereo line input modules, “remote location” can also
refer to a remote source machine that is feeding its audio to the module in
question. A 5VDC signal, as indicated below, will activate the module’s
channel ON and OFF switches.

REMOTE ON — Activates the module’s channel ON switch. Provide
a momentary 5VDC signal between Pins 16 (Remote On A) and 17
(Remote Common A) or Pins 22 (Remote On B) and 23 (Remote Common
B). This will latch the module ON.

REMOTE OFF — Activates the module’s channel OFF switch.
Provide a momentary 5VDC signal between Pins 3 (Remote Off A) and 17
(Remote Common A) or Pins 9 (Remote Off B) and 23 (Remote Common
B). This will latch the module OFF.

COUGH — Temporarily Mutes the module. Provide a momentary
5VDC signal between Pins 1 (Cough A) and Pin 17 (Remote Common A)
or Pins 7 (Cough B) and 23 (Remote Common B). This will turn the
module OFF. Note this is a non-latching mode; the module will turn ON
again as soon as the signal stops. (User-supplied momentary contact
switch required.)

Note that these are opto-isolated inputs and require a signal of the
correct polarity. The Remote Common A and Remote Common B Pins
will always be positive relative to the Pins for the other signals (Remote
On A and B, Remote Off A and B, and Cough A and B).

Typical DB-25

connector

Talkback to Control Room

If a module is being used for a studio microphone, these ports allow
talkback from that studio to the console operator in the control room.
Provide a momentary 5V signal between Pins 14 (TB to CR A) and 17
(Remote Common A) or Pins 20 (TB to CR B) and 23 (Remote Common
B), with positive end of the signal going to the Remote Common A or B
pin. This will cause two things to happen: (1) the module’s pre-fader signal
is sent to the console’s Cue bus, where it may be heard by the console
operator, and (2) the module’s Cough function is activated, muting the
module’s post fader signal and preventing the TB signal from going out
over other assigned busses (i.e., “live”). This non-latching condition
continues until the signal is removed. (Requires user-supplied momentary
action talkback switch at the control room microphone location.)

D-8000 / Jan 2003

page 2 – 6

DIGITAL/ANALOG INPUT

Talkback to Studio

Provide a momentary 5V signal between Pin 13 (TB to Studio) and 17
(Remote Common A) or Pins 13 (TB to Studio) and 23 (Remote Common
B) to send the module’s pre-fader signal to TB output of studio module
through TB monitor.

On and Off Tallies

ON TALLY—Lets the module’s channel ON switch control an on-air
light or other indicator at a remote location. This control function provides
a continuous closure between Pin 15 (On Tally A) or Pin 21 (On Tally B)
and Pin 19 (Digital Ground) whenever the module’s channel ON is
activated.

OFF TALLY—Lets the module’s channel OFF switch control an on­air light or other indicator at a remote location. This control function
provides a continuous closure between Pin 2 (Off Tally A) or Pin 8 (Off
Tally B) and Pin 19 (Digital Ground) whenever the module’s channel ON
is NOT activated.

The On and Off Tallies can be used to control externally powered tally
lights that require a continuous closure to function, or external tally lights
(i.e., LED) can be powered from the input module by connecting the
external LED to +5V Digital (Pin 25)* and the A or B On or Off Tally ports
(Pin 15, 21, 2 or 8). In any case, current should not exceed 30 milliamps.

*We recommend a series
resistor between the LED
and Digital Ground when
you are powering the ex­ternal tally from the con­sole; a value of 220Ω (1/
4W 5%) is suggested.

To START and STOP Remote Source Machines Using Module ON/
OFF Switches

EXTERNAL START — Hook up the remote machine’s “start” control
pins to the module’s lower DB-25 connector control pins: for START A
wire to pins 18 and 5; for START B wire to pins 24 and 11.

EXTERNAL STOP — Hook up the remote machine’s “stop” control
pins to the module’s lower DB-25 connector control pins: for STOP A wire
to pins 6 and 5; for STOP B wire to pins 12 and 11.

Note that these are opto isolated outputs.

To Control the Module’s OFF Switch LED with an External Source
Machine

READY — Hook up the remote machine’s “ready” control pins to the
module’s lower DB-25 connector control pins: for READY A wire to pins
4 (Ready A) and 17 (Remote Common A); for READY B wire to pins 10
(Ready B) and 23 (Remote Common B). The module’s Ready ports are
looking for a 5VDC signal of the correct polarity, with the positive end of
the signal going to the Remote Common A and B pin. As long as the
voltage is maintained, the OFF switch LED will be illuminated.

MIC PREAMPS MODULE

Mic Preamplifier Module

(MP-8)

Module Overview

MP-8 module is used for microphone input signals (-50dBu
nominal). Each module accepts eight mono sources. Phantom power
is available at each input ports; it may be selectively activated by
internal dipswitches SW1 and SW2 (the factory default is OFF).
Recessed front panel multi-turn trimpots (range 38dB) adjust input
levels.

Example: with a microphone input of –60dBm @150Ω at the port,

gain trim can set levels from -22dBu to +16dBu (note maximum preamp
gain is +76dB).

The MP-8 module outputs are wired to inputs of any type of
analog/digital input modules (IN-8, INM-8, and/or INDM-8).

All audio input and output signals are made via two multi-pin
DB-25 connectors mounted in the bottom of the console’s main­frame, directly underneath the module.

Phantom Power

Two four-position dipswitches SW1 & SW2 turn phantom power on

and off for the module’s eight microphone input ports.

SW1 position 1 activates phantom power for microphone 1
SW1 position 2 activates phantom power for microphone 2
SW1 position 3 activates phantom power for microphone 3
SW1 position 4 activates phantom power for microphone 4

SW2 position 1 activates phantom power for microphone 5
SW2 position 2 activates phantom power for microphone 6
SW2 position 3 activates phantom power for microphone 7
SW2 position 4 activates phantom power for microphone 8

Hook-Ups

As stated before, all user wiring to and from the MP-8 module takes
place at DB-25 multi-pin connectors mounted directly beneath the module
on the console mainframe’s bottom pan. There are two connectors per
module: the upper one (towards the console meterbridge) handles audio
inputs signals; the lower (near the console armrest) audio outputs signals.
A pinout drawing on page 3-5 shows all wiring connections at a glance.

Note the factory default
setting for phantom power
is OFF.

Audio Inputs Connections (upper DB-25)

All signals are analog mono. The mic input level is nominally -50dBu.

OUTPUT MODULES

Output Modules

(OMD-8)

Module Overview

Each D-8000 console has two standard (MASTER A
and MASTER B) output modules and one optional
(MASTER C) output module. MASTER A module
handles the console’s Program and Auxiliary outputs,
MASTER B handles Audition and Utility and MASTER
C handles Send1 and Send 2.

MASTER A output module has installed jumpers J3,
J4 for Program output; J7, J8 for Auxiliary output; and
J11, J12 for CUE monitor signal.

MASTER B output module has installed jumpers J5,
J6 for Audition output; J9, J10 for Utility output; and
J13, J14 for TEL monitor signal.

MASTER A or MASTER B module can be changed
to the other by making the appropriate jumper changes.

All modules output analog and digital signals. Ana­log outputs may be adjusted using recessed front panel
multi-turn trimpots.

Master A and Master B modules also generate the
console’s monitor signals, which feed the Control Room,
Studio and Meter Output modules. There are analog
stereo insert points for PGM and AUD (these may be
internally bypassed, which is the factory default setting).
Regardless of the bypass switch setting, INSERT OUT
may be used as an additional direct PGM (or AUD)
output from a module.

All user wiring to and from the OMD-8 modules
takes place at DB-25 multi-pin connectors mounted
directly beneath the module on the console mainframe’s
bottom pan. There are two connectors: the upper one
(towards the console meterbridge) handles analog out­puts and insert points; the lower connector (near the
console armrest) handles digital outputs (AES format).
All analog audio is +4dBu balanced. Pinout drawings on
pages 4-6, 4-7 and 4-8 show all wiring connections at a
glance.

OUTPUT MODULES

Internal Programming Options

Insert Bypass

Virtually all internal programming switches on the OMD-8 modules are
for factory use only. There is one exception, however, and that is the INSERT
BYPASS slide switch SW2, located near the top of the PCB just above the four
front panel analog trimpots. The factory default for this switch is “down”; i.e.,
the module’s PGM (or AUD) insert points are bridged. To use the PGM (or
AUD) insert points (located on the upper DB-25 connector) throw the switch
“up”.

For the purposes of this manual, we will assume you are holding the removed
module upright, component side towards you, with gold-plated card fingers to the
left and the module faceplate to the right.

CONTROL ROOM MODULE

Control Room Module

(CRD-8)

Module Overview

The CRD-8 module is the D-8000 console operator’s monitor
module. It allows him to listen to the console’s four stereo outputs
(PGM, AUD, AUX & UTL) as well as two external stereo line level
inputs brought directly into the module. Source SELECT switching for
these signals is at the top of the module.

The CRD-8 also houses console HEADPHONE and CONTROL
ROOM circuits, which follow the source selection switches.

There are two types of headphone output: the +4dBu balanced output at
the module’s upper DB-25 connector (pre-level control), and two head­phone jacks mounted left and right on the front of the lower mainframe pan,
which are actually outputs from a built-in headphone amplifier. It is this
built-in amp that is controlled by the module’s front panel HEADPHONE
level control.

The CUE master level control is right in the center of the module;
this sets the level of the CUE output and set the volume of console’s
CUE speakers.

Whenever CUE is activated elsewhere on the console (stereo line
inputs, or the superphone module or for studio talkback) its signal will
appear at the console’s built-in left and right cue speakers mounted in the
meterbridge. Depending on how the CRD-8 module has been programmed,
cue can also interrupt the control room monitor speakers and/or the console
operator’s headphone. The way Cue interrupts the module’s headphone and
CR outputs is determined by an internal PCB-mounted dipswitch. See “Cue
Interrupt” on next page.

All user wiring to and from the CRD-8 module takes place at
DB-25 multi-pin connectors mounted directly beneath the module on
the console mainframe’s bottom pan. There are two connectors: the
upper one (towards the console meterbridge) handles audio outputs and
the console on-air tally control signals; the lower (near the console
armrest) accepts the two external source inputs. All audio connections
are stereo line level analog signals (+4dBu balanced). A pinout
drawing on page 5-6 shows all wiring connections at a glance.

D-8000 / Jan 2003

page 5 – 2

CONTROL ROOM MODULE

Internal Programming Options

There are two user-programmable switches on the CRD-8. One is a 7­position dipswitch, SW1, located on the module’s main PCB slightly
above and to the left of the cue master level control. This sets various cue
interrupt modes (see below).

There is also a single slide switch, located on the back edge of the
module’s piggyback PCB, which selects stereo or mono cue (see below).

For the purposes of this manual, we will assume you are holding the re­moved module upright, component side towards you, with gold-plated card
fingers to the left and the module faceplate to the right. This will enable you to
read the control legends silkscreened next to each programming switch. Note
when a dipswitch position is thrown to the right (towards the module’s face­plate) it is ON.

Cue Interrupt

Seven-position dipswitch SW1 determines how the console’s Cue

function will interrupt regular monitor signals:

Dipswitch position 1 sends cue to CR left
Dipswitch position 2 sends cue to CR right
Dipswitch position 3 sends cue to HDPN left*
Dipswitch position 4 sends cue to HDPN right*

*factory default settings

Cue Mute

As Cue is also fed to the console’s built-in meterbridge speakers, where
it can easily be picked up by the console operator’s microphone, there is
provision to mute Cue whenever that mic is live (i.e., whenever the control
room mute function is activated).

Dipswitch SW1 position 7 will mute cue whenever CR is muted
(this is the factory default setting)

Mono Cue

Cue is normally a stereo signal; however, mono cue is possible. Simply
throw slide switch SW1 on the piggyback “cue” card in the direction of the
silkscreened arrow (down). This will send a summed L+R cue signal to
both cue left and right signal paths. Note the factory default setting for this
switch is stereo cue.

External Cue Input

An additional Cue input is provided on the lower DB connector to
allow an external signal to feed the console cue bus. See pinout informa­tion on the following pages.

The console’s on-air tally port is on the CRD-8 upper DB-25
connector. This is a simple relay closure that activates whenever
programmed input modules are turned ON. The port can be used to
control an externally powered tally light that requires a continuous
closure to function.

Studio Control Module

Module Overview

STUDIO CONTROL MODULE

(SCD-8)

The SCD-8 module is similar to the CRD-8 control room
module, only it controls monitor audio and talkback to two
additional (“non-control room”) studios. The monitor signal be­ing sent to these two studios following the source select switching
at the top of the module (this switching is identical to the control
room module’s and includes the console’s four stereo outputs
(PGM, AUD, AUX & UTL) as well as two external stereo line
level inputs brought directly into the module.

There can be two modules per console to control a total of four
studios.

Each studio has its own level control and talkback switch.
When a talkback switch is pressed (they are momentary action) the
console operator’s microphone signal will interrupt the regular
monitor signals being sent to the studio in question. The
TALKBACK master level control in the center of the module sets
the talkback output and the level of the talkback interrupt signal.

All user wiring to and from the SCD-8 module takes place at
DB-25 multi-pin connectors mounted directly beneath the module
on the console mainframe’s bottom pan. There are two connec­tors: the upper one (towards the console meterbridge) handles
external talkback out and regular studio monitor outputs, plus the
console’s Tally 2 and Tally 3 control signals; the lower connector
(near the console armrest) accepts the module’s two external
source inputs. It also outputs two additional pre-level control
studio outputs. All audio connections are (+4dBu balanced) ana­log signals. A pinout drawing on page 6-6 shows all wiring
connections at a glance.

STUDIO CONTROL MODULE

Internal Programming Options

There is one user-programmable dipswitch on the SCD-8. It is a 7­position dipswitch, SW1, located on the module’s main PCB slightly above
and to the left of the talkback master level control.

For the purposes of this manual, we will assume you are holding the removed
module upright, component side towards you, with gold-plated card fingers to the
left and the module faceplate to the right. This will enable you to read the control
legends silkscreened next to the programming switch. Note when a dipswitch
position is thrown to the right (towards the module’s faceplate) it is ON.

External Talkback Mute/Dim

There is an independent talkback output from the SCD-8 module (see
upper DB-25 connector page 6-6). By programming the first two positions
of dipswitch SW1, you can make this external talkback output MUTE
whenever a studio is muted. You also have the option of making the output
DIM (drop -20dB in level) instead of MUTE.

Dipswitch position 1 mutes external TB whenever Studio 1 is muted*
Dipswitch position 2 mutes external TB whenever Studio 2 is muted*
Dipswitch position 7 makes external TB DIM instead of MUTE

*factory default settings

Studio Dim

Input modules controlling studio microphones can be programmed to
MUTE a studio whenever the module is turned on (i.e., it’s microphone is
live). If you wish, you can have a studio DIM (drop -20dB in level) instead
of MUTE:

Dipswitch position 5 causes Studio 1 to DIM instead of MUTE
Dipswitch position 6 causes Studio 2 to DIM instead of MUTE

Note the DIM functions do not affect talkback interrupts, which always
completely replace the studio’s regular monitor feed with the console operator’s
TB signal. Note also if a studio is muted, talkback cannot be heard. However, if a
studio is programmed to DIM instead of MUTE, talkback audio could presum­ably make it from the studio monitor speakers to the open studio mic.

METER OUTPUT MODULE

Meter Output Module

(DMTR-8; standard

DMTRS-8; optional)

Module Overview

Each D-8000 console has one of the two types of meter
output modules: a standard DMTR-8 module, which is installed
with the standard central processor module CPU-8 (described in
chapter 8), or an optional DMTRS-8, which goes with optional
CPU-8S module. Each output module drives the console’s four
pairs of left-right VU meters: PGM, AUD, AUX and SWT
(switched). The switched meter follows the SELECT switching
at the top of the module, allowing the console operator to meter
AUD, AUX and UTL (DMTR-8 module); or SEND 1, SEND
2 and UTL (DMTRS-8 module), and two digital or analog
(+4dBu balanced) external stereo line signals which may be
brought into the module on its lower DB-25 connector.

The meter output module also houses the master CUE LED
indicator. Whenever Cue is activated anywhere on the console
this LED will illuminate and the CUE signal will automatically
appear on the switched VU meter pair. When cue is de­activated, the switched meter pair goes back to its previously
selected signal.

At the bottom of the module are the timer control buttons
(the timer display is mounted in the righthand end of the console
meterbridge):

AUTO – enables timer restart functions from programmed input

modules.

S/S – Start/Stop.

RESET - return to zero (if the timer is stopped it will hold at
zero; if it is running it will reset to zero and immediately begin
counting up).

HOLD – when held down freezes the timer display (the counter
keeps on going); when released the display catches up to the current
count.

D-8000 / Jan 2003

STANDARD

OPTIONAL

page 7 – 2

METER OUTPUT MODULE

All user wiring to and from the DMTR-8 (DMTRS-8) module takes
place at the lower DB-25 multi-pin connector mounted directly beneath
the module on the console mainframe’s bottom pan. This lower connector
(near the console armrest) inputs the module’s two analog or digital
external stereo line signals. See the pinout drawing on page 7-5.

While there are two DB-25 connectors, the upper one (towards the console
meterbridge) is for factory use only. It sends the module’s PGM, AUD, AUX
and SWT data, the master clock data, and timer control signals to the
meterbridge (a factory-provided cable runs from this upper DB-25 to a match­ing connector mounted at the back of the meterbridge, in the center of the
console).

Internal Programming Options

Internal programming is made via printed circuit board (PCB) mounted

switch SW1 on the module’s main card.

For the purposes of this manual, we will assume you are holding the re­moved module upright, component side towards you, with gold-plated card
fingers to the left and the module faceplate to the right. This will enable you to
read the control legends silkscreened next to each programming switch. Note
when a dipswitch position is thrown to the right (towards the module’s face­plate) it is ON.

External In

Dipswitch SW1 is used to select analog or digital inputs for the two
EXT signals. SW1 position 1 controls the EXT 1 port and SW1 position
2 controls the EXT 2 port, as follows:

SW1 pos 1 ON sets EXT 1 to be a digital input

SW1 pos 1 OFF sets EXT 1 to be an analog input

SW1 pos 2 ON sets EXT 2 to be a digital input

SW1 pos 2 OFF sets EXT 2 to be an analog input

Hook-Ups

As stated before the only user wiring into the DMTR-8/DMTRS-8
module is two external digital or analog (+4dBu balanced) stereo line
inputs on the module’s LOWER DB-25 connector.

(CPU-8/CPU-8S

(DSP-8 Module)

Overview

Every D-8000 has these two modules; together
they perform all central signal and control processing
for the console. The CPU-8 or CPU-8S is the console’s
central controller module; the DSP-8 is the console’s
digital signal processor.

The D-8000 Digital Audio console is provided
with a serial interface port, which is located on the
lower DB-25 connector of the CPU-8 or CPU-8S
module (see connection diagrams for pinouts and
other details). This serial interface is designed to
provide a number of functions including external
control and set-up, software updates, system inter­face, etc. Through this serial interface, the D-8000
control protocol is available, allowing visibility and
control of the console switches, displays, and other
functions. The “Virtual Dip Switch” application pro­gram (supplied with the D-8000 console) communi­cates set up information through this serial interface
(see Chapter 9).

There are no user replaceable parts inside (though
complete modules may be ordered; see Appendix I).

CPU & DSP MODULES

CPU-8/CPU-8S

The CPU module is the master control module for the D-8000 Digital
Audio Console. By monitoring the various console modules and serial ports,
the CPU controls all of the console audio and logic functions. Because the
system architecture is designed to work by communicating function and
status changes, the D-8000 console is very responsive and fault tolerant. The
console will even continue to pass audio signals with the CPU module
removed; however this module must be present to change levels or channel
assignments.

Both CPU-8 and CPU-8S have several functions and modes that can be
configured by the user. These are normally set to default values at the
factory, and should not be altered casually.

1. The first function is the console ID address. This function is set using
DIP switches SW-2 - SW-3. This address is used to identify the console
serial interface port so that external devices such as automation systems, the
VDip software, and external controllers will communicate with the console
correctly. Because the D-8000 serial interface port can be configured as an
RS-485 device, and multiple consoles can be connected to the same RS-485
bus, each console needs a unique address to identify it properly on the bus,
ensuring that the right commands get passed to the correct console. The
specific address set is unimportant except that any external controller must
use a matching address to communicate with the console. The address is set
with the DIP switches in binary format (for example with all switches “OFF”
the address is “0”, with the first switch “ON”, the address is “1”, with just
the second switch “ON” the address is “2”, with the first and second switches
“ON” the address is “3” and so on). Consult the section “Internal Program­ming Options”, page 8-9, for more details. The D-8000 console is normally
configured with an address of “1”. Do not change the console address unless
you are using the console in an RS-485 bus system.

2. The second function is serial interface configuration. DIP switches
SW-7 & SW-8 control the serial interface protocol and termination respec­tively for the two serial ports on the CPU module. These ports can be
configured as RS-232 or RS-485, and terminated or unterminated via these
DIP switches. In particular, COM Ø is designed to be used only with the
optional EQ controller. Again, the default settings of these switches are for
normal operations and should not be changed unless you are using the
console in an RS-485 bus system. Consult the sections “D-8000 Serial
Interface”, page 8-7, and “Internal Programming Options”, page
10-9, for specific configurations. SW-4, position 1, is also used with the
serial interface; by setting it “ON”, the normal checksum in the serial
protocol is disabled. This can be useful with some external control devices
which are not equipped to generate a checksum in their messages.

A momentary push-button switch, SW1, is accessible through a hole in
the front panel to toggle COM1 between RS-232 and RS-485 operation. The
front panel RS-232 LED indicates that the port is in RS-232 mode when lit,
and RS-485 mode when not lit. Upon console power-up, the port will be
configured according to dipswitch SW7 position 2, which should be set for

D-8000 / Jan 2003

D-8000 / Jan 2004

page 8 – 3

CPU & DSP MODULES

the mode you normally want the port to operate in. This ability to switch the
port mode is useful in a system where the console is normally connected to
the Wheatstone Bridge 2001 via an RS-485 link, and the necessity arises to
reconfigure a channel using VDip on a computer with an RS-232 port.
Assuming that you’re provided wiring from both the RS-232 and RS-485
outputs of COM1, all you then need to do to switch between router operation
and VDip is to press the recessed switch. Press it again to toggle back to the
original mode.

3. The third function is nominal audio make-up gain. DIP switch
SW-5 is used to establish the master gain setting for the D-8000 console.
This allows users to configure the nominal fader setting and signal head­room to suit their specific needs or preferences. The digital audio signals
entering the D-8000 console are usually normalized in the recording or
transmitting process for peak signals such that the absolute maximum peak
signal is very close to, but does not exceed, the maximum or highest digital
word in the AES bit stream. This implies that any decrease in signal caused
by placing the console fader at a “normal” setting somewhat less than full
up needs to be made up at the output of the console or the signal will be lower
than it was at the source. Radio consoles are normally operated with their
faders at less than full up to allow for some control over level and mixing
(if a signal is too low or quiet, the fader can be moved up until the signal
matches the normal levels as shown in the console meters.). By using the DIP
switches, the user can configure what the normal fader setting (and hence the
output make-up gain) should be. Consult the “Global Gain” table in the
“Internal Programming Options” section, page 8-9, for the gain values. The
D-8000 console is normally shipped with a make-up gain setting of +12dB
for a nominal fader setting of -12dB from the top. The gain value briefly
shows in the CPU display window during the console power up process
(“12--00dB” indicates +12dB gain). Note that setting the make-up gain too
high for the signals and fader settings used can result in a clipped or distorted
signal, just as it could with an analog console.

4. The fourth function is the CPU display window. The eight characters
displayed in this window are used to communicate general information to
the user. During the power up process, the CPU tests each module for proper
communications; any errors found will be displayed in the CPU display
window. Once the module communications have been tested, the CPU
briefly shows the selected make-up gain (see above), and then displays
<PRESETXX>, where XX indicates the current console preset number
(01 - 99). Pressing the “Preset Select Knob” alternately displays
“REMOTE <>” and “REMOTE><“ to indicate normal operation (if the
console has been fitted with the optional EQ controller the display alternates
between “REMOTE /\” and “REMOTE \/” indicating correct communica­tions with the EQ controller). If the CPU detects an error during normal
operations, it will show the error message in the display window. If you see
such a message, make a note of it and contact Wheatstone Technical Support
for instructions. Note that the alternate display is changed to “LOCAL <>”
and “LOCAL ><“ (or “LOCAL /\” and “LOCAL \/” in the case of EQ
controller versions) when the console serial interface has been de-activated
by pressing the large red button on the CPU module.

5. The fifth function is serial interface control. The front panel of the
CPU module has a large pushbutton switch. Activating this switch will
enable the remote serial interface to the console (REMOTE), and de­activating the switch will disable the remote serial interface. When the
interface is activated, any device connected to the interface can control any
of the console functions. Note that the console operator also has control of
the console functions even when the remote serial interface is enabled.; the
console will respond to any command regardless of where it comes from.
When the interface is disabled (LOCAL), the console will not respond to
any commands sent to the remote serial interface; it will respond only to
the console switches and faders.

The D-8000 console with the CPU-8S module has three additional

functions.

1. The first additional function is the console’s send controls. Sends
(SEND 1 and SEND 2) are used to provide special effect feeds or custom
monitor mixes to specific locations. The SEND controls work in conjuction
with DSP equipped input modules. For example, press the SET button on
an INDM-8. Then press the SEND1 ON button and rotate the SEND 1
control clockwise. The LEDs surrounding the SEND 1 control give an
indication of the level of the post fader post on/off signal from the chosen
INDM-8 that will feed the SEND 1 output (located in the OMD-8
MASTER C module). Press the PRE FDR button to take a pre fader signal
from the INDM-8. The PRE ON button provides a pre on/off signal.
SEND 2 works in a similar manner.

If SET is pressed on an input module that has already been assigned to
a SEND, the controls for that SEND will light to indicate the settings of that
input in the SEND output. Modules may be assigned to one or both sends,
or to neither send, as desired.

Two CUE switches (one for each SEND) place the send signals on the
console’s stereo cue bus where it may be heard on the meterbridge
mounted cue speakers and/or as an interrupt to the console operator’s
headphones and control room monitor speakers. The various cue interrupt
modes are programmed at the console’s CRD-8 (Control Room) module
via internal PCB-mounted dipswitches.

2. The second additional function is console’s preset security level. A
three digit password is entered to change the security level. Hold in the
SEND1 knob and turn the PRESET SELECT knob to indicate the desired
first digit of the password (0-9). Press the TAKE button to accept this first
digit, then turn PRESET SELECT again to dial up the second digit. Use
TAKE to accept the second digit, turn PRESET SELECT again to the
desired value of digit three, and press TAKE one more time. The security
level will change to that granted by the password so entered.

Note that the three digit password code can be changed from the VDIP

application. See the VDIP section for details.

CPU & DSP MODULES

The LED’s on the front panel (next to the “TAKE” switch) indicate

security levels:

“GST” (GUEST) - allows operation of controls, but not recalling of

presets. (Default code is any non USR or ADM three digit code).

“USR” (USER) - allows operation of controls and calling up presets, but

not recording any changes. (Default code is 123).

“ADM” (ADMINISTRATOR) - allows operation of controls, calling up

presets, modifying and saving presets. (Default code is 777).

3. The third additional function is to select and store console presets.

PLAYBACK PRESETS

On power up, the last preset number taken is displayed in the CPU
window. Presets have fixed, non-editable names “PRESET01”-“PRESET99”.
You can view and playback other preset names by rotating the PRESET
SELECT knob. If you stop at a preset, the display will indicate that preset
name for 4 seconds, then revert to normal. If you press the TAKE button
while a preset is showing, you will playback that preset. Each preset is stored
in the console’s memory.

RECORDING PRESETS

Holding down the TAKE button for over 1 second will record all current
control surface settings into the current preset number (assuming the security
access allows it). You must rotate the PRESET SELECT knob to the desired
number before pressing TAKE. Recorded settings include all input module
switches, fader levels, EQ panel switches and levels.

In the event that the console is powered down, upon the next power up
the console will assume the settings of the preset that was current before the
power was removed.

Note: Superphone
module fader and
switch settings are not
recorded.

DSP-8

The DSP-8 is the main audio mixing module in the D-8000 Digital Audio
Console. It functions solely as a mix engine, combining all of the console
audio signals as directed by the console faders and switches to produce the
various output mixes for PROGRAM, AUDITION, AUXILIARY,
UTILITY, SEND, CUE, and TELEPHONE. These mixes are sent from the
DSP-8 module to the various output modules over the console backplane.
There are no user settings or switches on the DSP-8 module; however the
external AES clock sync and slave connections appear on the upper DB-25
connector on this module. See the hook-ups section, page 8-11, for connec­tion information.

The DSP-8 module operates at a factory set sample rate, normally 48kHz,
which dictates the output sample rate of the D-8000 console digital outputs.
Consult Wheatstone Tech Support if you wish to use a different output
sample rate. Since all of the console digital inputs are equipped with sample
rate converters, the console inputs will accept any sample rate between the
range of 1/2 to twice the output sample rate, and will actually track a variable
sample rate as long as it remains within this range. This feature allows you
to interface different types of digital sources into the console, each with
different sample rates.

D-8000 Serial Interface

Using the Serial Interface

The D-8000 Serial Interface is designed to support serial communica­tions under the RS-422/485 and -232 protocols. The proper serial interface
protocol must be selected (via DIP switches on the CPU module) or else
serial communications will not function correctly. No serial interface
connections are required for normal, stand alone operation of the D-8000
console; in fact the console will work normally even with an improper
connection to the serial interface. The function of the serial interface is to
enable remote operation of the D-8000 console functions; local operation
of the console switches and faders will always override any remote
commands that may have been sent via the serial interface. In addition, the
large button on the CPU module can be used to disable any serial
communications with the D-8000 console. Toggling the switch “ON” and
“OFF” alternately enables and disables the serial interface port on the D­8000 console. When the PRESET SELECT knob is pressed, the 8-digit
display on the CPU module shows “LOCAL” when the serial interface is
disabled, and “REMOTE” when the serial interface is active. Remember,
the D-8000 console can always be controlled by its faders and switches
regardless of the status of the serial interface. If remote control of the
console is desired, the remote mode must be selected with the CPU switch,
and the display must read “REMOTE”.

The most common use for the D-8000 Serial Interface is to allow
configuration changes (mutes, tallys, etc.) by means of the “Virtual Dip
Switch” program supplied with the console and described in Chapter 9 of
this manual. To do this, the “Virtual Dip Switch” program must first be
installed on a suitable PC, and a serial cable connected from the COM port
of your PC to the lower DB-25 connector on the CPU module. Be sure that
the RS-232 mode for the console serial interface (the default setting) has
been selected via the DIP switches on the CPU module. Push the button on
the CPU module to enable remote operation and start the program on the
PC. Use the program as described in this manual to modify the D-8000
console configuration. Once the configuration has been set, the PC can be
disconnected from the console.

A second common use for the D-8000 Serial Interface is to allow
alphanumeric information to be written to the console input channel
displays by an automation system. By making a suitable serial connection
between the automation system and the D-8000 serial interface (RS-232
or -485), and enabling remote operation via the CPU front panel switch,
the console displays can be updated with cut information, etc., by an
automation system. As the number of systems that have connectivity to the
console for this function is constantly changing, please consult Wheat­stone for the latest information on automation interfaces. Our Technical
Support engineers can assist you with pinouts, switch settings, .INI files,
etc., as required for your particular system.

D-8000 / Jan 2003

page 8 – 7

CPU & DSP MODULES

Another use for the D-8000 Serial Interface is for complete remote
operation by an external control system. When used in this way, the
D-8000 console acts as a passive listener to the serial interface awaiting
D-8000 serial protocol commands. Any external system that can deliver
serial text strings in the proper D-8000 serial protocol format will be able
to control the console. Consult Wheatstone Technical Support for more
details on enabling this functionality.

CPU & DSP MODULES

Internal Programming Options (CPU)

All internal programming is made via printed circuit board (PCB)
mounted switches on the module’s card. With the exception of the reset
and serial select switches, which are momentary push-button switches, all
programming is via 4-position dipswitches (total six).

For the purposes of this manual, we will assume you are holding the re­moved module upright, component side towards you, with gold-plated card
fingers to the left and the module faceplate to the right. This will enable you to
read the control legends silkscreened next to each programming switch. Note
when a dipswitch position is thrown to the right (towards the module’s face­plate) it is ON.

Global Settings

Four-position dipswitches SW2-SW5 (lower right corner of card)

determines various console operating parameters:

Bit Weight
SW2 position 11 0 1
SW2 position 12 1 2
SW2 position 13 2 4

Console

SW2 position 14 3 8

ID

SW3 position 21 4 16
SW3 position 22 5 32
SW3 position 23 6 64
SW3 position 24 7 128

Note: Each D-8000 Console ID# is set using dipswitch positions 11-14
and 21-24. These switches are read as an 8 bit field with Bit Ø mapped to
DSW11 and Bit 7 mapped to DSW24. This ID# is read by the CPU at boot
up and is required by D-8000 serial communications software.

Example: Desired ID=17, set DSW21 and DSW11 “ON”

In multi-console, RS-485 connected system, each D-8000 console
MUST have a unique Console ID#. Default Console ID is 1
(DSW11=”ON”).

SW4 position 31- Ignore serial input checksum byte

Misc

(default is “OFF”)
SW4 position 32 - Not used
SW4 position 33 - Not used

SW7 - RS-485/RS-232 Select

Four position dipswitch SW7 located on the upper right side of card
selects the hardware interface type (RS-485 or RS-232) for each serial Com
port.

SW7 position 2 RS-485 RS-232 Com 1
SW7 position 3 Not used
SW7 position 4 Not used

SW8 - RS-485 Termination

Four position dipswitch SW8 located right next to the card’s short upper
row of gold fingers is used for RS-485 termination. Termination must be
switched in pairs (i.e., TX and RX BOTH ON or BOTH OFF) for a given
Com X port.

OFF ON Serial Port
SW8 position 1 Not terminated Terminated Com Ø - TX
SW8 position 2 Not terminated Terminated Com Ø - RX
SW8 position 3 Not terminated Terminated Com 1 - TX
SW8 position 4 Not terminated Terminated Com 1 - RX

CPU Reset Switch

Push-button switch SW6 with green cap (lower right side of card) will
reset the CPU hardware and initiate a re-boot of the CPU firmware. This
sequence is sometimes called a “soft boot”, because the console’s power
supply is not cycled OFF/ON.

VIRTUAL DIP SWITCH

Virtual Dip Switch

Virtual Dip Switch Application Program

The application “VDip” is included with the Wheatstone D-8000
Digital Audio console. It is designed to run on any Windows compatible
PC. When the correct serial port of the external PC that contains the VDip
program is connected to the D-8000 serial interface port, the program can
be used to alter certain configuration details (mutes, tallies, etc.) in the
D-8000 console as well as to modify the text displayed in the console
8-character displays. These details can be saved to a file and called up at
a later date, thus making it easy to change console set-ups by running the
VDip program and restoring a previously saved file.

Installation

To install VDip, first be sure that the PC you wish to use is Windows
compliant, has a CD ROM drive, has at least 50 Mb of hard disk storage
available, and has an available serial port mapped to COM 1, COM 2,
COM 3, or COM 4. Install the software on the PC by loading the VDip CD
that came with the D-8000 console into the drive tray and then running the
install wizard on the CD by double-clicking on “Setup.exe”. Note, if your
CD ROM drive is configured for Auto Play, the install program will
automatically start when you insert the VDip CD in the drive. Follow the
instructions on the screen to complete the installation. When finished,
store the CD in a safe place in case you need to install the software on
another machine in the future.

Hooking Up the Computer

Refer to the diagram on page 9-14 of this chapter showing the proper
connections for the serial cable connecting the external PC with the
D-8000 serial interface port which is located on the lower DB-25 connec­tor of the CPU-8 module. Wire and test the cable. Note that there are certain
DIP switch settings on the CPU-8 module which must match the serial port
on your external PC. The console is shipped with the D-8000 serial
interface set up for a normal RS-232 connection. If your external PC has
an available RS-232 connection (which most do) you do not need to
modify any of the settings on the CPU-8 module. If you are planning on
using an RS-485 connection to the D-8000 serial interface (to allow
multiple consoles and/or multiple controllers to be connected on a com­mon bus), your PC must have an available RS-485 port ( most do not) and
you must make changes to the settings on the CPU-8 module to set up the
proper format, addresses, and terminations for an RS-485 system. If you
are planning to use RS-485, consult the “D-8000 Serial Interface” part of

D-8000 / Jan 2003

page 9 – 2

VIRTUAL DIP SWITCH

this manual for the details on configuring for RS-485. If you are not certain
which interface to use or have questions on these details, consult our
Wheatstone Technical Service engineers. Establishing serial communica­tions between two different pieces of equipment can sometimes be
frustrating; we can provide answers to your questions, and even pre-made
cables to make the process easier.

Running the Program

Be sure that the serial interface cable is plugged into the CPU-8 lower
DB-25 connector on one end, and the proper COM port on your PC at the
other. Also be sure that the large button on the front of the CPU-8 module
has been switched to “Remote” and that the CPU-8 display shows
“Remote”. The VDip program will not communicate with the console
unless the console has been set to “Remote”. Start the program as you
would any Windows program by double-clicking on its shortcut, or
choosing the program from the START/PROGRAMS menu. Once the
program opens, you should see a screen shown below. This is the start-up

screen for the program, and is used any time you wish to alter the
connection status for the program. Select “Communications...” from the
“Setup” menu with your mouse and then select the correct “COM” port to
match your computer. Also verify that the “Virtual Dip Switch Program
ID” is set to “1”. This is the standard setting (for networked operations this
DIP switch setting must be altered; consult Wheatstone technical support).

D-8000 / Jan 2003

page 9 – 3

VIRTUAL DIP SWITCH

Leave the settings for Baud Rate and Handshaking as shown below.

Once the correct “COM” port is selected, click on “OK” to accept these
settings. Click on “Connect” under the “file” menu to establish communi­cations with the D-8000 console. Verify that the Console ID is set to “1”
(standard setting).

D-8000 / Jan 2003

page 9 – 4

VIRTUAL DIP SWITCH

Using the Program

Once you have established communications with the console, the
various screens and menus can be used to control the console functions.
The program will inquire about the current settings in the console and will
display them to you on the status display screen. This screen shows the
status of all of the input module functions, one module at a time. Functions
can be changed by clicking on the function with your mouse; a selected
function shows a check box, a de-selected function shows a blank box.
Towards the bottom right of the window is an area where you can enter text
to be displayed on the input module display. Note that there are two boxes,
one for “A” and one for “B”; different text can be entered in these boxes
such that switching from input “A” to input “B” on the module automati­cally changes the display. You might for instance label the input channel
“A” display “NEWS” and the “B” display “GUEST 2” to correspond to
how your console audio is wired. Any standard keyboard character can be
used; just remember that the displays are limited to 8 characters, including
blanks and punctuation.

VDip Main Screen (shown for IN-8 module)

VDip Main Screen shows Console configuration for each slot and
allows you to make /change settings for each console's input module.

The numbered Tabs represent the console’s input slots. Click on a Tab
to see the status for that slot. Each framed area on the resulting slot display
groups together functionality that can be enabled, disabled, or otherwise
controlled for that slot.

VIRTUAL DIP SWITCH

Source—IN-8 module can be programmed for either "Digi­tal" or "Analog" input separately for each source A and B.

Enable Functions—"Cue Switch" (located on the module's
faceplate) can be Enabled/Disabled by checking/unchecking
box separately for each source A and B.

"IFB AES out" (located on the module's lower DB-25) can
be Enabled/Disabled by checking/unchecking box separately
for each source A and B.

Superphone Auto Assign—IN-8 output assign switches can
be controlled by the console's SPD-8 Super Phone module(s).
Check Boxes will slave selected output assign switches to
follow Super Phone output assign switch control pulses.
Once again the A and B sources are individually configured.

In order for this feature to work, an associated dipswitch
on the Super Phone PCB (SW1) must be programmed as well.

Utility Bus Assign—When activated, will cause the module
signal assigned to the console's UTL output to be tapped
before the fader and the channel ON/OFF switches, config­ured separately for each source A and B.

Talkback to Studio—IN-8 module can be used as talkback
mic, placing the signal (post-insert, pre-fader) onto the
console's talkback bus. When the console operator presses a
TB switch on the console's SCD-8 Studio Control module, the
talkback bus (which is carrying his microphone signal) will
interrupt the regular monitor signal being fed to the studio and
talent will hear his voice through the studio monitor speakers.

There are three check boxes for both A and B sources
which will control the module’s assignment to the Talkback
bus. Please note that there is some interaction between the
check boxes.

External Switch - assigns the module’s signal to the
Talkback bus when an external user-supplied TB switch is
pressed. The switch provides a momentary closure between
the module's lower DB-25 connector TB to Studio (pin 13)
and A Remote Common (pin 17) or B Remote Common (pin

23). If the Assign box is checked (see below) the External
Switch check box is ignored. If the On/Off Follow box is
checked (see below) the module must be ON for the external
TB switch to work.

Assign - if checked by itself this check box causes the
module’s signal to continually feed the Talkback bus. If the
On/Off Follow box is checked then the module’s signal feeds
the Talkback bus only when the module is ON. When Assign
is checked, checking or unchecking the External Switch box
will have no effect.

D-8000 / Jan 2003

D-8000 / Aug 2003

page 9 – 6

VIRTUAL DIP SWITCH

On/Off Follow - by itself this box has no effect. Check­ing it will modify the behavior of the External Switch or
Assign check boxes so that the module’s signal is assigned
to the Talkback bus only when the module is ON.

TB to IFB—When the TB button on the IN-8 module’s
front panel is pressed, the module’s IFB output is normally
interrupted (replaced) by the TB bus signal. If the “IFB
Dim” box is checked, the IFB output is dimmed (dropped
by 20dB in level) instead of being completely replaced (or
muted). If the “IFB Cue Mute” box is checked, the IN-8
module will not feed the console CUE bus when the
module’s TB switch is pressed. Once again, A and B
sources can be individually configured.

Cue Controls—When the CUE button on the front panel is
pressed it will assign the module’s signal to the CUE bus for
both A and B sources. Note "Enable Functions" / "Cue
Switch" has to be activated first.

When "Drop Out" is checked it causes the module's
CUE function to be de-activated whenever the channel ON
switch is pressed.

When "Post Fader" is checked the level of signal on the
Cue bus will follow the module's Fader position.

TB to CR Mutes—In order for someone in the studio to
reply to the console operator, the IN-8 module signal for
that microphone must be routed to the console's Cue bus,
where it can interrupt the regular control room monitor feed
and be heard by the operator. This is accomplished by user­supplied TB to CR switches. The switches provide a mo­mentary closure between the module's lower DB-25 con­nector TB to CR A or TB to CR B control pins and Remote
Common. As long as this closure is maintained the module's
signal will be placed on the console's Cue bus. Simulta­neously, the module's regular output will be muted so the
talkback signal doesn't go out over the air.

If "Studio 1" or "Studio 2" is checked and the TB to CR
A or TB to CR B pressed, then the Studio 1 or Studio 2
output will be Muted or Dimed (whether Muted or Dimmed
depends on dipswich settings on the SC-8 module).

Off Channel LED—The module's channel OFF switch
normally has its LED indicator controlled by the switch
itself ("local"). This is the factory default setting. However,
should you wish to have the LED function as a "ready" light
for an external source machine, optional box "Ready"
passes control to opto-isolated A and B "ready" ports on the
module's lower DB-25 connector, where a 5 Volt signal
applied with correct polarity will activate the OFF switch
LED. As long as the voltage is maintained, the LED will be
lit.

Input A Mutes—IN-8 module can be programmed to mute
the control room or studio speakers when the channel is ON.
The D-8000 has three mute control lines. Each of these may
be activated by either an A or B source.

Control Room - mutes the control room when checked
and source A is ON

Studio 1 - mutes studio one when checked and source A
is ON

Studio 2 - mutes studio two when checked and source A
is ON

Input B Mutes

Control Room - mutes the control room when checked
and source B is ON

Studio 1 - mutes studio one when checked and source B
is ON

Studio 2 - mutes studio two when checked and source B
is ON

Input A Tallies—Turning the module ON can activate a
remote tally indicator. There are three tally control lines: "On
Air Tally (1), "Tally2", "Tally3". Remote tallies are hooked­up to the console at the Control Room (On Air Tally (1)) and
Studio (Tally2, Tally3) modules.

On Air Tally - activates the On-Air Tally control line
when checked and source A is ON

Tally2 - activates the Tally2 control line when checked
and source A is ON

Tally3 - activates the Tally3 control line when checked
and source A is ON

Input B Tallies

On Air Tally - activates the On-Air Tally control line when
checked and source B is ON

Tally2 - activates the Tally2 control line when checked
and source B is ON

Tally3 - activates the Tally3 control line when checked
and source B is ON

Timer Reset—The console's digital timer
can be programmed to automatically reset to
zero and begin counting up when the module's

ON button is pressed. To enable this func­tion the “AUTO” button on the meter output module has to be
activated. A and B sources are individually configured.

Input Display—You can enter or edit text

to be displayed on the IN-8 module display.

Text boxes for "A" and "B" sources can be

used such that switching from input "A" to
input "B" on the module automatically changes the display.

D-8000 / Jan 2003

D-8000 / Aug 2003

page 9 – 8

VIRTUAL DIP SWITCH

Any standard keyboard characters can be used. Displays are
limited to 8 characters, including blanks and punctuation.

Fader Control—Allows the fader position to control CUE and/
or fader on/off status (European Fader Start, or EFS). A and B
sources are individually configured.

Fader Cue - will assign the module's signal to the Cue bus
when the fader is moved all the way down. "Enable Functions"
/ "Cue Switch" has to be activated first.

EFS - will turn the module OFF when the fader is moved all
the way down and turn the module ON when the fader moves
from the fulldown position.

Remote Start—This setting allows you to correct for differing
source machine ON/OFF control signals to the IN-8 module.
When set to "Const", the module will work with most standard
source machines. Occasionally, the source machine, because of
the way it is designed, will send overly long control closures to
the module's remote ON and OFF ports - closures so long that
they will hang up the module's ON/OFF logic. When this kind of
problem manifests itself, setting to "Pulse" will convert the
closures to pulses before they get to the channel ON/OFF switch
logic.

Example: IN-8 set to default "Const". The external source
machine reaches end-of-play and sends a five second (or longer)
OFF signal to the module, effectively holding it in an OFF state.
You press the module ON switch but nothing happens - because
the OFF switch is locked up. By setting the option box to "Pulse"
this type of problem is eliminated: the module is turned off and
left immediately ready for further control input.

"Remote Start" / "Start/Stop" allows you to follow "Pulse"/
"Const" settings not just for the module's ON/OFF switches but
also for the module’s Remote START/STOP outputs. That is,
when “Remote Start”/”Start/Stop” is checked, a module on
signal from a remote machine will turn the module on and will
also cause a START logic output from the module; when this is
not checked, the START output is not generated from a module
on signal, but is still generated when the module ON switch is
pressed.

"Remote Start" - "Pulse", "Const", ”Start/Stop” functions
may be activated by either an A or B source.

Input Attenuation (dB)—This exclusive Wheatstone digital
console feature allows the user to digitally "trim" the gain back
on any input module. While this feature is most useful for
reigning in "hot" digital domain sources on SRC input modules,
digital attenuation may also be applied to any analog line level
source. Note that the digital attenuation occurs after the analog
pre-amp stages, therefore, clipping in those stages can not be
corrected with this feature (use analog trim pots located on the
input module).

D-8000 / Jan 2003

D-8000 / Aug 2003

page 9 – 9

VIRTUAL DIP SWITCH

There are Combo Boxes for selecting the desired input attenuation. The
attenuation choices are 0db to -14dB in 2 dB steps. Simply click to select
the attenuation value and then "WRITE" the selected change to the
module. You can use the "Write Slot" toolbar icon or the "Slot" menu item
to write the current attenuation setting along with any other module
settings. The attenuation setting is immediately written to the correspond­ing channel.

Why use digital attenuation?

Many of today's digital audio sources (especially modern rock, rap,
etc.) are produced to take full advantage of the available maximum digital
output level (0dBFS). Playback of these tracks from a CD player's digital
output result in average digital domain levels -6 to -3dBFS or higher! That
translates to average analog levels of +18 to +21 dBu; very close to the
console's clipping point of +24dBu. Connecting the digital output from a
CD player to a console input with gain on the fader can put the operator in
a position of potentially clipping the CD playback. In this case, adding ­12dB of attenuation will re-calibrate the input module so that digital
clipping of CD source material will be impossible even if the operator
pushes the fader all the way to the top.

Saving Changes

Just as you saved the new attennuation settings, in a similar manner you
can save other changes you have made with VDip. Once you have finished
setting the text and configuration that you wish for an input channel, you
send the information to the console by selecting “Write Current” under the

“Slot” menu. The information is then sent to the console, and the input
channel display will be updated to the text you chose. To select another
input channel to modify, choose its corresponding slot number from the
selection bar near the top of the status display screen. The status screen will
change to show the type and settings of the module in the slot you have
selected. If you choose a slot number that has no module installed, the
status screen will show “NO CARD”. By selecting each slot and changing

D-8000 / Jan 2003

D-8000 / Aug 2003

page 9 – 10

VIRTUAL DIP SWITCH

the display text and settings, the entire D-8000 console can be configured
to suit your application. Remember, you must select a channel to be
modified before you can make changes, and you must “Write Current” after
making the changes to pass them on to the console.

Advanced Operation

After using the VDip program for a while, its operation becomes
routine. There are some advanced features to make it easier to do repetitious
tasks. Underneath the top menu bar of the status screen is a row of “buttons”
designed to perform routine tasks like “Write Current” and “Read Current”.
Moving your mouse pointer over a button and leaving it there for a moment
will bring up a short “hint” message on screen that explains the button’s
function. Also, under the “Console Configuration” and “Slot Configura­tion” menus (under “File”) are functions called “Save To File” and “ Load
From File”. Choosing “Save To File” allows you to save all of the console

settings under a filename which you can retrieve later using the “Load From
File” function. This makes it easy to recall complex but repeatable text and
settings information into the console, especially if you name the file
something obvious like “7am”, etc.

You can have a large number of files saved, limited only by your ability
to give them suitable names.

Changing D-8000 Password Codes on the CPU-8

There are three levels of security to “Preset” configurations on the D­8000 console: ADM (administrator), USR (user), and GST (guest).
Accessing each level is accomplished through certain sequences of button/
knob activity on the CPU-8 module as described on page 8-5.

To change the three digit security code for ADM or USR select
“Console - Change Password” from the VDIP main menu bar.

D-8000 / Jan 2003

Once selected a password edit window
will appear. Radio style buttons select
either Admin (Administrator) or User.
Simply enter the Old Password, New
Password and Confirm New Password,
then click OK. The new three digit
code will be written to the CPU-8.
Note that a successful serial connec­tion must be made prior to changing
any access code.

Default codes for new consoles are
ADM = 777
USR = 123
GST = any non-ADM or USR three

digit code.

VIRTUAL DIP SWITCH

Ending the Program

Once the console text and settings are to your liking, and have been
written to the console, and saved to a file if desired, the VDip program can
be ended by selecting “Exit” from the “File” menu. The console settings
will remain as you have set them until the next time the VDip program is
run. You can remove the computer connection or leave it hooked up, as you
desire. Note that if you leave the connection to the computer in place, you
should set the large switch on the CPU-8 module to “local” in case some
other program on the computer tries to write to the COM port. It is unlikely
that a stray message sent out the COM port will cause any changes because
the message will be ignored unless it is sent in the precise D-8000 serial
protocol, but simply switching the console to “local” provides extra
insurance.

SUPERPHONE INPUT

Superphone Input

(SPD-8; optional)

Module Overview

SPD-8 input modules are used for telephone call-ins. Each
module can handle two callers; there can be two modules per
console for a total of four callers. Caller signals enter the module
from your station hybrid; each caller has his own fader. Caller input
gain trims are provided at the top of the module.

Output switches assign callers to any combination of the console’s
four stereo outputs: PGM (program), AUD (audition), AUX
(auxiliary) and/or UTL (utility). When the module is assigned to
PGM and turned ON, a red “Air” LED illuminates just above the
output assign switches.

Caller Set-Ups

Pre-air segment communication between the console operator
(DJ) and callers is via CALLER SETUP buttons (2) which place the
caller’s voice on the console’s cue speakers (or control room
speakers/operator’s headphone if the CRD-8 module’s cue inter­rupt function has been so programmed). These cue signals can be
internally programmed pre or post fader.

The caller hears the DJ in one of two ways:

1) The DJ can assign his microphone input module to an unused
output bus—say UTL—and the DJ then selects the UTL input with
the MXM SOURCE switch at the top of the phone module. This
sends a dedicated (digitally generated) version of the UTL bus
signal to the SPD-8 module’s hybrid output, where it is ultimately
heard by the caller through his telephone. This mix minus source
select method can also be used to preplay a musical segment (or any
other program content) for the caller off-air. Take the input module
handling the desired music cut and assign it to an unused output bus;
select the same bus as the caller’s mix minus source input and he will
hear it off-air.

Remember IN/INM/INDM-8 input modules can be internally pro­grammed to have their Utility bus feed tapped pre-fader, pre-ON/OFF,
making this a logical set-up for the DJ’s mic input if you do a lot of call­in work, since the DJ’s voice will always be present on the console’s
Utility output bus regardless of fader or ON/OFF settings on his mic
module (which must still be assigned to UTL, however).

2) The DJ’s voice signal can be inputted through a special EXT

IN port at the SPD-8 module’s DB-25 connector. This second

D-8000 / Jan 2003

SUPERPHONE INPUT

method eliminates the need to select a mix minus input source every
time you want to talk off-air to the caller. An easy source choice
here would be DJ mic module’s INSERT OUT port.

Automatic Features

Regular mic and stereo line input modules can have their output
assign buttons slave off of the SPD-8 telephone module output
buttons. If this feature has been programmed on desired source
modules, when it’s time to go on-air with a phone segment all you
need do is hit PGM on the phone module, and the PGM button on,
say, your CD input module (and the DJ’s mic module) will follow
suit.

Note while this feature will turn slaved assign buttons ON, it will

not turn them OFF; you must do this manually.

Faders can be optionally equipped with end-of-travel CUE
switches, which will allow you to talk off-air with a caller with a
simple fader overpress. One of the faders can also have an optional
EFS type switch to automatically turn the module on when it is run
up.

The channel ON (red) and OFF (orange) switches are at the
bottom of the module. These can be programmed (via internal
PCB-mounted dipswitches) to activate control room and studio
mutes, tallies, timer restart and automatic cue drop-out. The ON
switch can also automatically trigger an external tape machine for
recording purposes (see page 10-7).

Cue Dropout can also be programmed internally, making it
unnecessary to de-activate caller setup buttons before going live;
simply pressing the module’s ON switch will automatically do this
for you.

Inputs and Outputs

All audio and control signal hook-ups are made via two multi­pin DB-25 connectors mounted in the bottom of the console’s
mainframe, directly underneath each module. The upper connector
handles hybrid input signals (i.e., caller input) and the external
input mentioned on page 10-2. The lower connector handles
outputs, including the module1 and 2 feeds to your station hybrid
(the phone signals going to your callers).

The module also has three addition output feeds on the lower
DB-25 connector. These are generally used for recording purposes:

Composite Out – This includes everything: DJ, callers, music

beds, etc. Generally used to to record phone segments in
advance of actual airplay.

Composite Minus Callers – This includes everything but the

callers.

Callers Only – No talent, no DJs, no music; just caller voices.

SUPERPHONE INPUT

Internal Programming Options
Main Printed Circuit Board

Main card internal programming is accomplished via three 4-position
printed circuit board (PCB) mounted dipswitches mounted just to the left
of the module’s faders.

For main PCB programming, we will assume you are holding the removed
module upright, component side towards you, with gold-plated card fingers to
the left and the module faceplate to the right. This will enable you to read the
control legends silkscreened next to each dipswitch. Note when a dipswitch
position is thrown to the right (towards the module’s faceplate) it is ON.

Output Assign Switch Enable

As previously stated the input modules (IN-8, INM-8, and INDM-8)
can have their output assign switches slave off of the
SPD-8 phone module output assign switches. Four-position dipswitch
SW1 (top dipswitch just to the left of the module faders) enables this
feature at the phone module end:

SW1 position 1 activates PGM switch control
SW1 position 2 activates AUD switch control
SW1 position 3 activates AUX switch control
SW1 position 4 activates UTL switch control

The feature must also be enabled on desired input modules using VDip
software.

Note this feature only
works for turning slaved
assign switches ON; they
will not turn OFF from the
superphone module—this
must be done manually.

Mutes

When the SPD-8 phone channel ON switch is pressed, it can activate
console mute functions. The first three positions of dipswitch SW2 (just
below dipswitch SW1) determine which of the console’s three mute lines
will be activated:

SW2 position 1 mutes the control room when the phone module is
ON*
SW2 position 2 mutes studio one when the phone module is ON
SW2 position 3 mutes studio two when the phone module is ON

Timer Restart

When the module is turned ON, the console’s digital timer can be
programmed to automatically reset to zero (and begin counting up if it is
runnig).

SW2 position 4 activates timer restart when the phone module’s ON
switch is pressed*

Tallies

Turning the module ON can activate a remote tally indicator. There are
three tally control lines: on-air, tally 2 and tally 3. The first three positions
of dipswitch SW3 (to the left of the fader) program these functions:

SW3 position 1 activates the on-air tally control line (requires PGM
assign)

*factory default setting

*factory default setting

Remote tallies are
hooked-up to the console
at the Control Room mod­ule (CRD-8)

D-8000 / Jan 2003

page 10 – 4

SUPERPHONE INPUT

SW3 position 2 activates tally 2
SW3 position 3 activates tally 3

Cue Dropout

Dipswitch SW3 position 4, when activated, will cause CUE (i.e., caller
set-up buttons 1 & 2) to turn off when the module’s ON switch is pressed.
This is the factory default setting.

Gain Trimpots

There are two PCB-mounted trimpots. They are used as follows:

CR1 - sets Callers 1 In port input gain
CR2 - sets Callers 2 In port input gain

Internal Programming Options
Piggyback Card

Piggyback card internal programming is accomplished via two PCB­mounted slide switches on the module’s piggyback card. This same card
also contains PCB-mounted trimpots which may be used to set the
module’s various output feed levels.

For piggyback card programming, hold the removed module horizontally,
component side towards you, with gold-plated card fingers aimed down and the
module faceplate on top. This will enable you to read the control legends
silkscreened on the PCB.

External In

In addition to feeding the DJ’s voice signal to the callers via the
module’s mix minus source select switching, it may also be brought
directly in through an EXT IN port on the module’s upper DB-25
connector. PCB-mounted slide switch SW1 (piggyback card left center),
activates this external port when thrown to the left (this is the factory
default setting).

Cue Pre/Post

The module’s CUE signals (caller setup buttons 1 & 2) can tap pre or
post fader. When slide switch SW2 (piggyback card lower right) is UP they
are PRE, when DOWN they are POST. (Factory default setting is PRE.)

Gain Trimpots

There are six PCB-mounted trimpots to the right of slide switch SW1.
They are used as follows:

CR4 – sets the External In port input gain
CR6 – sets the module’s output level to Hybrid 1
CR3 – sets the module’s output level to Hybrid 2
CR7 – sets the module’s “composite” output level
CR8 – sets the module’s “composite minus callers” (“talent”)

output level

CR5 – sets the module’s “callers only” output level

Factory default settings for
these trimpots is UNITY
GAIN.

Hook-Ups

As stated before, all user wiring to and from SPD-8 modules takes place
at DB-25 multi-pin connectors mounted directly beneath each module on
the console mainframe’s bottom pan. There are two connectors per module:
the upper one (towards the console meterbridge) handles audio input
signals; the lower (near the console armrest) audio outputs and control
signals. A pinout drawing on page 10-8 shows all wiring connections at a
glance.

(LSD-8 Controller Panel and

LSR-500 Rackmount Unit;

optional)

Overview

This optional module consists of an 8-switch control module
(LSD-8) mounted in the D-8000 console and an associated 19-inch
rackmount switcher (LSR-500) that mounts in a remote location. All
audio input and output wiring goes to the rackmount unit, which takes
its control from the console module.

The rack unit accepts eight stereo analog and digital audio inputs
(each input is dipswitch-selectable for either analog or digital) and
outputs both an analog and digital stereo signal, which may be wired
back to D-8000 console input ports. Wiring between the console’s
LSD-8 preselector module and the rackmount switcher is via two
factory supplied pin-for-pin DB-25 connector cables: the module’s
upper DB is used for control; the lower for power.

The LSR-500 rackmount unit faceplate has eight indicator LEDs
which show which input has been selected at the console and also
ANALOG and DIGITAL LEDs which light to show what kind of
signal has been selected. A POWER LED is also included. (See
drawing next page.)

The rear of the LSR-500 has seven I/O connectors: two DB-9s
(analog and digital output) and five DB-25s (control and power to the
LSD-8 module, analog audio in (2) and digital audio in (1). In the center
of the chassis rear is a cutout that allows access to eight dipswitch
settings that determine what type of audio (analog or digital) each input
accepts. The default setting (“off”) is DIGITAL.
