Attention!
This console contains static sensitive devices:
Normal precautions against static discharge should be observed when
handlingindividualmodules.Inparticular, modulesbeingpackedforshipping
for return or repair must be packed in special static protection bags before
packaging. Damage caused by static discharge may not be covered under
warranty.
Replacing Modules in a Powered-up Console:
While in an emergency situation it is possible to remove and insert modules
on a powered-up console, Wheatstone does not recommend this procedure.
Whenever possible it is best to power down the console first before removing
or replacing modules.
However, if you find you must proceed with this operation, then be sure to
take the following precaution:
When re-inserting a module, take care to replug it squarely into its
mainframe connector socket, so all edgecard fingers make contact
simultaneously. In other words, the gold-plated bus connector fingers on the
bottom edge of the module's printed circuit board must be inserted squarely
(i.e., perpendicular) to the mating socket on the bottom pan of the console
mainframe. The intent is to prevent a situation where one of the module's
power pins makes significant contact before the others. (Naturally, this
same precaution must be taken when using extenders.)
Iftheaboveinstructionsarefollowedtheprocedureshouldberoutine;ifthey
are not, you could run the risk of damaging the console's logic chips.
Again, to avoid ANY possibility of this damage, whenever possible we
stronglyrecommendpoweringdowntheconsolebeforereplacinganymodules.

Console Clock Battery Backup
Attention!
Console Clock Display Card
To activate battery backup of the console’s clock simply pull out the yellow
strip from the clock display card, that is mounted on the inside of console
meterbridge, as shown on the picture below.

Your Audioarts RD 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.

CountertopMounting
The RD digital audio console is designed for countertop drop-in
mounting. Console placement should avoid proximity to any electro-
magneticfields,suchaslargepowertransformers,motors,andfluores-
centlightingfixtures.The required cut-out widthis315/8” for RD-12
or 43 5/8” for RD-20, and cut-out front-to-back dimension is 18 3/8”.
Thefrontoftheconsolewillextendapproximatelyoneinchforwardof
thecut-out.Theconsole’swoodensidepieceswillextendabout7/8”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 approxi-
mately 5 1/2 inches below the countertop surface. Note the hinged
meterbridge will require 10 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 RD console to its power supply (and do not
connectthepowersupplytotheACpowerline)untilinstructedto
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 RD mainframe are connected
togetherattheconsole,butareNOTconnectedtoelectricalgroundand
the chassis of the power supply. Safety requirements dictate that a

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
rightmostmainframeslots(tothelowerleftifyouarelookingattherear

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.

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.

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 encoun-
tered 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.
Locateallunbalancedaudioequipment in thesamerackifpossible, to
minimize chassis ground potential differences. It may also be helpful to
insulateeachpieceofunbalancedequipmentfromitsmountingrailsinthe
rackbymeansofnylon10-32screwsandinsulatingwashersbetweenrails
and faceplates.
Once the system is properly grounded, proceed with the console
power supply installation and connection (next section).
Power Supplies
The RD console is powered by a Wheatstone Model PSC-D340
rackmount power supply. This heavy duty unit occupies three 19” wide
rack spaces (total height 5-1/4”). Convection cooled, it requires ample
ventilation space above and below it. The PSC-D340 generates a lot of
heat in the course of normal operation — do not mount heat sensitive
devices in the same rack cabinet.
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
locatinganyhighgainequipment(suchasphonopreamps,taperecorders,
etc.) too near the rackmount supplies, to avoid magnetic interference into
that equipment.

Once the supply is rackmounted, it should be connected to the console
using the factory supplied cable. The console’s power supply connector is
located at the rear of the console, at the right end of the meterbridge bottom
pan. Note that the power supply cable’s 10-pin 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 first to the console, then to the rear of the rackmount power
supply.
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 RD console common; the console itself must be grounded
separately. (See previous section, "System Ground".)
The power feed recom-
mended in the text is of-
ten installed and referred
to in studios as an “iso-
lated AC ground” outlet.
It is usually orange in
color.

Audio and Control Wiring
Allaudio and control I/O connections to the RDconsole are made through
multipin DB-25 connectors located on the bottom of the console.
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
that this manual is organized by module type (inputs, outputs, monitor
modules, etc.); each chapter contains detailed wiring instructions for its
moduletype.Proceedthroughthemanual,chapterbychapter,untilallmodules
havebeen wiredto suityour particularinstallation requirements.Once proper
audiooperationisverified,gobacktoeachindividualchapterandproceedwith
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
toselectadigitalaudiocablewithanintegraldrainwireofthesamewiregauge
(AWG) as the twisted pair. Typical AES/EBU digital audio cable has a very
lowcharacteristiccapacitanceperft(pF/ft),andanominalimpedanceof110Ω.
Highquality digital audiocable offersbetter signal transmissionperformance
versus typical analog audio cable, especially over long cable runs. Check the
cablemanufactures data sheet to besure the cable you plan to use willwork in
your application.
CONNECTORS - All AES/EBU connections are made with the supplied
DB-25 male mating connectors. These crimp style connectors are the insula-
tion displacement type and will accept wire gauge 24 - 22AWG.
SPDIF INPUTS - The SPDIF (Sony/Philips Digital Interface) or “con-
sumer” digital audio interface is a two wire unbalanced signal typically on a
single RCA style connector. To connect SPDIF devices to the RD console
simply wire the SPDIF center conductor (HOT) to the SLD-5 “HI” input pin
and SPDIF shell (ground) to the SLD-5 “LO” input. Connect the SLD-5
“SHIELD” to the DB connector SHELL at the console end only.
Analog Insert Points
Certain module signals have insert patch points in their signal chains to
allow outboard audio processing. These include MONO MIC INPUTS
(MMD-5) and OUTPUT MODULES (OMD-5).
Normally these points are internally bridged at the factory (via PCB-
mounted programming switches) prior to shipment. If you intend to use
outboardsignal loopsat these points, you must reprogram theseswitches. See
pages 2-3 (mic inputs) and 4-3 (output modules) for details.
