Your Wheatstone A-5000 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 A-5000 audio console is designed for countertop drop-in
mounting. Console placement should avoid proximity to any electro-
magneticfields,suchaslargepowertransformers,motors,andfluores-
cent 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-outfront-to-backdimensionisalways185/8”.Thefrontofthe
consolewillextendapproximatelyoneinchforwardofthecut-out.The
console’s wooden sidepieces 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 connectthe A-5000consoleto itspower supply(anddo 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 A-5000 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

undertherightmostmainframeslots(tothelowerleftifyouarelooking

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.

(A)EARTHGROUND,whichisusuallyaheavycopperroddrivenintothe

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.

TIE THE CONSOLE GROUND LUG TERMINAL STRIP TO THE
SYSTEMEARTHGROUND. TIEEVERYPIECEOFEQUIPMENTIN
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 audioequipment inthe samerack ifpossible,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
TheA-5000consoleispoweredbyaWheatstoneModelPSRrackmount
power supply. The PSR unit occupies two 19” wide rack spaces (total
height3-1/2”)andcontainsuptofourSPS-180powersupplyunits.Donot
mount heat generating 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.

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.

Energizing
Assuming the A-5000 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.

Audio and Control Wiring
All audio and control I/O connections to the A-5000 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 snubcut andlaid outin order(although tubingshould beused 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.

Insert Points
Certain module signals have insert patch points in their signal chains
toallow outboardaudio processing.Theseinclude MONOMIC INPUTS
(MM-5000) and OUTPUT MODULES (OM-5000).
Normally these points are internally bridged at the factory (via PCB-
mounted programming switches) prior to shipment. If you intend to use
outboardsignalloops atthese points,you mustreprogramtheseswitches.
See pages 2-3 (mic inputs) and 4-3 (output modules) for details.

OUTPUTS — A-5000 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 HIGH or

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