Cleaning the Acrylic Surface
An acrylic surface is a beautiful, lustrous material that is outstanding in
durability and break resistance. With proper care, it will retain its attractive
appearanceformanyyearstocome.Thiscareshouldincludeprecautionsagainst
scratchingorcontactwithobjectsofhightemperaturethatmightmarthesurface.
A few simple precautions will preserve the beauty of the acrylic.
• FIRST be sure the surface to be cleaned is powered off.
• NEVER spray or pour any liquid directly onto the surface.
• TO AVOID scratching these surfaces, use a soft brush or cloth to gently
brushawayanylargerdirtparticles.Alternatelythelargerparticlescanbeblown
from the surface with the use of canned air.
• USE a soft, clean lint free cloth or micro fiber cloth and clean lukewarm
water to clean the surface. For stubborn dirt and stains use a mild, nonabrasive
soap and water mixture with the gentle cleaning cloth. Use only light pressure
when cleaning. Avoid rubbing dirt or grit into the surface. Turn the cloth often
andreplacewithacleanclothfrequently.Drybyblottinggentlywithaclean,dry
cloth.
• AVOID using kleenex, paper towels, sponges or other coarse shop towels,
as these materials may contain abrasives that can scratch acrylic surface.
• DO NOT USE ketones, aromatics, esters, halogens, window cleaning
sprays, alcohol, kitchen scouring compounds, or solvents (such as acetone,
benzene, gasoline, carbon tetrachloride, or thinners).

Control Surface Placement
The G-9 digital audio control surface is designed for countertop mounting.
Although the rubber feet on the bottom keep the surface from being easily moved
when simply placed on the counter, holes have been provided so that screws may
be used to mount the surface securely to the countertop. Carefully remove the
appropriate panels from the frame, screw the mainframe to the counter top, and
reinstalltheremovedpanels.Thefouravailableframesizesdimensions(ininches)
are shown in the drawings below.
Donotconnect theG-9 control surfaceto itspowersupply (anddo not connect
the power supply to the AC power line) until instructed to do so.

Power Supply
TheG-9controlsurfaceispoweredbyaWheatstoneModelSPS-180R
rackmount power supply, or an SPS-180 or SPS-400 power supply
installed in a Wheatstone Model PSR rackmount unit. Each of the units
occupies two 19” wide rack spaces (total height 3-1/2”). The PSR unit
houses up to four SPS-180 or up to two SPS-400 power supply units.
Note the power supply (supplies) should be mounted in an equipment
rack within fifteen feet of the control surface (but no closer than 3 feet).
Avoidlocatingany highgain equip-
ment (such as phono preamps, tape
recorders, etc.) too near the
rackmount supplies, to avoid mag-
netic interference into that equip-
ment.
Thispower supplycontains 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
SPS-180R,SPS-180orSPS-400unit
mustbereturnedtoWheatstoneCor-
poration for repair.
Once the supply is rackmounted,
it should be connected to the control
surface using the factory supplied
cable. The cable has two different
types of connectors on it: a 5-pin

connectors are located at the rear of the control surface, in the middle
of the meterbridge bottom pan. If you are using one supply, connect it
to one of the control surface connectors (it doesn’t matter which one).

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
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.
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 G-9 control surface mainframe is properly placed,
and its power supply (or supplies) correctly rackmounted and con-
nected to the control surface, you may now energize the rackmount
power supply by plugging it into the AC mains. The control surface's
LCD displays will illuminate and individual module switches will
assume factory default settings.
Note: To de-energize the control surface, unplug the rackmount
power supply’s AC cord from the AC mains. Never de-energize the
control surface by disconnecting the cable that connects the control
surface and power supply together.

I/O Connections
All user wiring to and from the G-9 control surface is made via
connectors located on the control surface’s rear panel. The female
DB-9 connector at the left end of the control surface’s rear connects to
the internal cue speaker and headphone jack. There are also two RJ-45
connectors for main and failsafe ethernet connections. CAT-5 or multi-
mode optical fiber Mixer Link connections are made via RJ-45 or SC
type optical connectors. Two 5-pin male connectors are for power
supply connections. VGA connections are made via the female DB-15
connector that is mounted next to the cue speaker connector. For all
wiring pinout connections refer to Chapter 6. Sketches below show
connector locations.
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 control
surface; it is auto-indexing, and allows individual wire connections to
The AMP tool insulation dis-
placement connector system.
Note the right angle hood with
self-locking tabs. The tool,
multipin connectors (with gold
plated pins) and latching
hoods are supplied with each
control surface.

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 wire ends is required; all that is
neededisthatthewires destinedfortheconnectorbesnubcutand laidout
in order (although tubing should be used on bare drain wires). An empty
DB-9 connector is inserted into the tool, indexed to the first pin, and the
wiresare insertedone byone intothe jawand thetrigger squeezed.In this
way a single multipin connector can be completely wired up in a minute
or two. These connectors will accept wire gauge 22 - 26 AWG.
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.Observethesideoftheconnector,withthemetalpartdown.You

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
system. These have locking screws that hold the connectors securely to
their mates.

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.

(2) AUX encoders, (2) bank se-
lectswitches(AUX1/2andAUX

PRE FDR, and PRE ON) for
controlling the (4) AUX SEND
buses. Operation is as follows:
first “DOBBY” or momentarily
press one of the encoders to se-
lect which group of AUX
SENDS (AUX 1/2 or AUX 3/4)
is being worked on. The LED at the bottom center 6 o’clock position

bank select button will select which AUX SEND within the group is
being worked on. A lighted switch indicates you are working on an
evennumberedgroup (2or 4).Once thedesired AUXSENDhas been
selectedusingthesecontrols,theON,PREFDR,andPREONswitches
and the encoder can be adjusted for that particular AUX SEND.
Subsequently, the bank select switch can be pressed or the encoder
“DOBBIED” to choose the next AUX SEND, and so on.

feature is activated for a given channel by pressing the channel’s SET
button (see page 2-4).
PAN/BALANCE Knob
The PAN knob (in the EFS CONTROL panel) acts as a panpot in
MONO, LEFT only and RIGHT only modes; and as a balance control
in STEREO mode. Once again, this feature is activated for a given
channel by pressing the channel’s SET button. To easily set the PAN
to center, you can press the control twice in rapid succession, like
double-clicking a mouse button.

Each input channel can generate its own independent mix-minus
output, called BUS MINUS; thus each anchor, each announcer, each
host,eachguestcanhave
a dedicated mix-minus
feed.
Start by assigning
any desired input chan-
nels to the Bus Minus
bus. This is accom-
plished by pressing the
