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).

Introduction
The D-7 Digital Audio Control Surface is a member of Wheatstone’s line of
intercompatible D-series control surfaces with the functions and control capability
neededbytelevision broadcast facilities:5.1 digital surround,four stereo subgroup
mixes, two stereo sends, mix-minus master with eight mix-minus outputs, and two
mute groups. Above each fader on the input panel is a channel ON switch, an
8-character dot matrix source display, a PFL switch, eight mix-minus and four
subgroupassignmentdisplays,twostereobusassigns,twomutesdisplays,twoAUX
encoders with ON switches, and a source select encoder. It’s got four monitor
outputs (each with source displays), automatic telephone support, an event recall
system (with security function), and an array of user-programmable switches.
Designed to integrate flawlessly with the Wheatstone BRIDGE digital audio
network router, the D-7 control surface allows you to easily create large or small
platform-based systems that are exceptionally user-friendly and flexible. Wheat-
stoneBRIDGEnetworkcageshouseallI/Oportsandenginecards,andmaybewired
in tandem within a single equipment room or interconnected to separate remote
locations by means of CAT5 cables to provide single wire studio integration
schemes.
Once configurated, the system operates entirely independently of external
computers.Configurationitself is intuitiveand carried outonsite by meansof user-
friendly graphic interfaces provided by Wheatstone desktop software. The D-7
surface also takes full advantage of Wheatstone’s exclusive VDip configuration
software,sothatstudio functions(likemutes, faderandtimerstarts,tallies,etc.)are
easilyaccomplishedright atyourdesktop.Once completed,allsettingsareretained
in non-volatile storage, allowing the entire system to run independently. Ethernet
protocol is built in, providing interface with automation, scheduling, and hardware
controllers as you require.

Power Supply
The D-7 control surface is powered by a Wheatstone Model PSU-1
rackmount power supply. This unit occupies two 19” wide rack spaces
(total height 3-1/2”). Convection cooled, it requires ample ventilation
space above and below it.
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).
Avoid locating any high gain equip-
ment (such as phono preamps, tape
recorders,etc.)tooneartherackmount
supplies, to avoid magnetic interfer-
ence into that equipment.
Oncethesupplyisrackmounted,it
should be connected to the control
surface using the factory supplied
cable.Thecablehastwodifferenttypes
of connectors on it: a 5-pin female
connector that connects to the control
surface’spowersupplyconnector,and
an 8-pin male connector that plugs
into the power supply. The control
surface’s two power supply connec-
tors are located at the rear of the con-
trol surface, in the middle of the
meterbridge bottom pan. If you are

using the failsafe option (two PSU-1 supplies), connect one end of a
power supply cable to either control surface power connector and
connect the other end of the cable to one of the two power supply
connectors. Then use the other cable to connect the second power
supply connector to the remaining control surface power supply
connector.
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
sourcethat feedsonly thecontrol roomaudiogear.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 PSU-1 power
supplies for each piece of powered equipment. Though either is
capableofrunningafullloadonitsown,infailsafeoperationbothunits
runin tandem:ifonefails,the othertakesover,assuringuninterrupted
operation.
In order for failsafe systems to perform as designed, always have
BOTH rackmount supplies powered up and connected to their associ-
ated equipment.
Energizing
Assuming the D-7 control surface mainframe is properly placed,
and its PSU-1 power supply (or supplies) correctly rackmounted and
connectedtothecontrolsurface,youmaynowenergizetherackmount
power supply by plugging it into the AC mains. The “GOOD” LEDs

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.

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.
I/O Connections
All user wiring to and from the D-7 control surface is made via
connectors located on the control surface’s rear panel. Two 5-pin male
connectors at the center of the control surface’s rear are for power supply
connections. Headphone signal plugs into the female DB-9 connector,
located next to power supply connectors. This signal is routed to internal
amplifiers that feed headphone jack, located on the front right-hand side
of the surface’s pan. There are two RJ-45 connectors for Ethernet
(labeled ENET) and CAT-5 (labeled MIXER) connection. A DB-15
VGA monitor connector and two PS-2 connectors for keyboard and
mouse round out the rear panel. The sketch below shows connector
locations. For all wiring pinout connections refer to Chapter 5.
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
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 wire ends is required; all that
is needed is that the wires destined for the connector be snub cut and laid

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. 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.

Input Panel (IS-D7)
Controls and Functions
Each input panel of the D-7 digital audio control
surface has four identical strips representing four input
channels.
Input Sources
Each input panel controls four stereo sources. By
turningthesourceselector(SOURCEknob)atthetopof
the panel, the available inputs are displayed in the
8-character SOURCE display. When the desired input
source is scrolled into the SOURCE window, the SET
button will act like a TAKE button, and pressing it will
cause that source to be switched to the input of the
channel. If you fail to press SET, the display will revert
to its original setting after a timeout of approximately 4
seconds, and the original source remains in effect.
SET Button
This allows the operator to access various controls
and displays in the EFS CONTROL panel and apply
them to the selected channel. To use, press the SET
buttonandthenmakeyourappropriatesectionsettingsin
otherareasofthecontrolsurface.OnceaSETbuttonhas
beenpressed,thebuttonlightsup,andallsettingchanges
will apply to that input channel until a different input
SET button is pressed, or until a timeout of about 20
seconds has occurred.
AUX
Each channel of the input panel IS-D7 has two AUX
encoders (AUX1 and AUX2) to set the level of the
channel’saudiointheAUXSENDS.Two
switches (ON1 and ON2), determine
whether the channel feeds AUX1 (ON1)
and/or AUX2 (ON2).
