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
CountertopMounting
The D-8000 digital audio console is designed for countertop drop-
in mounting. Console placement should avoid proximity to any elec-
tromagnetic fields, such as large power transformers, motors, and
fluorescentlightingfixtures.Therequiredcut-outwidthisdetermined
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-outfront-to-backdimensionisalways185/8”.Thefrontofthe
consolewillextendapproximatelyoneinchforwardofthecut-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 approxi-
mately 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.
Donot connecttheD-8000 consoleto itspowersupply (anddonot
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 con-
nected 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

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 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.
Locateallunbalanced audioequipmentin 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 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
mindthatadequateventilationisnecessarytopreventheatbuild-upwithin
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
locatinganyhighgainequipment(suchasphonopreamps,taperecorders,
etc.) too near the rackmount supplies, to avoid magnetic interference into
that equipment.

removed! If you have a problem with the power supply, the unit must be
returned to Wheatstone Corporation for repair.

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
sourcethatfeedsonlythecontrolroomaudiogear. Thissourceshould
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-400powersuppliesforeachpieceofpoweredequipment.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 equip-
ment.
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

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
connectorpin.Thetechnologyissuchthatnostripping,solderingortinningof

connectorbe snubcutand laidoutin order(althoughtubing shouldbeused 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
tothefirstpin,andthewiresareinsertedonebyoneintothejawandthetrigger
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.

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.

Digital Audio Connections
CABLE-AllAES/EBUinputandoutputdigitalaudioconnectionsare
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
cablehasaverylowcharacteristiccapacitanceperft(pF/ft),andanominal
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.

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 PCB-
mounted programming switches) prior to shipment. If you intend to use
outboardsignalloops atthesepoints, youmustreprogramtheseswitches.
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
balancedsource. Atthe unbalancedsource machine’soutput, connectthe
blackwire(“LO”)totheshield.Ifthemachinehasa-10dBuoutput,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 trans-
former, 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 connec-
tions 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, Wheat-
stone 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.
