Installation and Power
Unpacking the Console
The R-55e console is shipped as two packages. One (larger) carton
containstheconsoleandtechnicaldocumentation;andtheother(smaller)
contains the rackmount power supply, connecting cable, and connector
kit.
CountertopMounting
The R-55e audio console is designed for countertop mounting. Con-
sole placement should avoid proximity to any electromagnetic fields,
such as large power transformers, motors, and fluorescent lighting
fixtures. If you will be securing the console to the counter top, you may
want to pre-drill the mounting holes (see sketch below).
Set the console in place on the counter, and remove the screws that
hold down the first and the last modules in place (two per module).
Carefully remove those modules from the frame. Attach the console
mainframe to the counter top, using the holes provided in the bottom of
the chassis and screws appropriate to the counter material, and reinstall
the removed modules.
Theconsoleextendsapproximately75/8”abovethecountertopatthe
meterbridge.Thehingedmeterbridgewillrequire14”abovethecountertop
surface and 4 3/4” behind the rear meterbridge to open freely.
Do not connect the R-55e console to its power supply (and do not
connectthepowersupplytotheACpowerline)untilinstructedtodo
so.
NOTE:Thisconsolecon-
tains static-sensitive de-
vices. Normal precau-
tions against static dis-
charge should be ob-
served when handling

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 R-55e 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
electrical ground be made in the completed installation. Use the
grounding lug on the rear of the mainframe to establish your system
ground. The grounding lug may be found at the rear of the console, on
the rear frame panel, to the left if you are looking at the rear of the
console.
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.

(B) THE POWER COMPANY EARTH CONDUCTOR that enters the build-
ing at the power line breaker box; this conductor should be (and is often by code)
tiedto the above-mentioned earth ground at one point. This point is the SYSTEM
EARTH GROUND.
TIE THE CONSOLE GROUND LUG TO THE SYSTEM EARTH
GROUND. TIE EVERY PIECE OF EQUIPMENT IN THE ENTIRE
AUDIO SYSTEM TO THE CONSOLE GROUND LUG. If the system
earthground point is inaccessible,tiethe console ground lugto 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; the
outletscannotbedaisy-chainedasisnormallyencounteredincommercial
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.
Locateallunbalancedaudio equipmentin thesame rackif possible,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).

R-55e / July 2004
INSTALLATION AND POWER
Power Supply
The R-55e console is powered by an Audioarts Model SPS-100
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 that the power supply should be mounted in an equipment rack
within fteen feet of the console (but no closer than 3 feet). Avoid locat-
ing any high gain equipment (such as phono preamps, tape recorders,
etc.) too near the rackmount supplies, to avoid magnetic interference
into that equipment.
Once the supply is rackmounted, it should be connected to the con-
sole using the factory supplied cable.
The cable has two different types of
connectors on it: an 8-pin female con-
nector that connects to the console’s
power supply connector, and an 8-pin
male connector that plugs into the
rear of the rackmount SPS-100 power
supply. The console’s power supply
connector is located at the rear of the
console, at the right end of the meter-
bridge bottom pan. If you are using
one supply, connect it to the console
connector. If you are using two sup-
plies (failsafe option), connect the long
power supply cable to the center con-
nector of the rackmount failsafe panel.
Then connect one supply with a short
cable to either of the two remaining
connectors on the failsafe panel and
connect the second supply with a short
cable to the last connector.
If failsafe redundant sup-
plies have been ordered,
you will be installing two
units and an additional
rackmount panel.

Note that each power supply is fitted with a 3-wire grounded AC
cordthatshould beplugged intoa"clean"ACpower source,that is,an
AC source that feeds only the control room audio gear. This source
shouldbe a separate feedfromthose powering lighting, air-condition-
ing,oranyothernon-audiomachinery.Thethirdpingroundwireofthe
AC source should be tied to the central system ground point.
Failsafe Dual Redundant Supply
Wheatstone failsafe power supply systems use two separate rack-
mount power supplies for each piece of powered equipment. 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 rackmount supplies powered up and connected to their associ-
ated equipment.
Energizing
Assuming the R-55e console mainframe is properly placed and
grounded, and its SPS-100 power supply correctly rackmounted and
connected to the console, you may now energize the power supply by
pluggingitintotheACmains.Theconsole'sVUmeterswillilluminate
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 R-55e console are made
through multipin DB-25 connectors located on the top of each module. The
output module also has a DB-9 connector. The factory supplied hand
crimping tool is used for all I/O wiring connections to and from the console
(see instruction on page 1-8).
ConnectionProcedures
As supplied from the factory, the console requires no logic connections
to function. Therefore an orderly installation begins with the audio wiring.
Note this manual is organized by module type (inputs, outputs, monitor
modules, etc.); each chapter contains detailed wiring instructions for its
module type. Proceed through the manual, chapter by chapter, until all
modules have been wired to suit your particular installation requirements.
Once proper audio operation is verified, go back to each individual chapter
and proceed with control wiring.
Unbalanced Connections (analog audio)
ANALOG INPUTS — Wire to the console with typical shielded two
conductorcable(likeBelden9451),justasifyouwereconnectingabalanced
source. At the unbalanced source machine’s output, connect the black wire
(LOW) to the shield. If the machine has a -10 dBu output, don’t hesitate to
turn module input gain as high as is needed.
ANALOGOUTPUTS—R-55econsolesuseanelectronicallybalanced
output circuit. Care must be exercised when connecting them to an unbal-
anced system. While temporarily shorting the low side of the output signal
to ground will not cause any problems, continued operation will result in
increased distortion, decreased reliability, and possible oscillation prob-
lems. If you must connect the output to an unbalanced system, be sure to
leave the low side unterminated, and connect the unbalanced system to the
high side output and shield connections.
Modules Layout
TheR-55econsole’smainframecomessuppliedwithupto20(for26pos.
frame), 12 (for 18 pos. frame), or 8 (for 12 pos. frame) line level input
modules along with an output module, and a control room/studio module.
Each module type has its assigned slot (see drawings on pages 1-11, 11-12,
and 1-13). To handle mic level inputs, a quad mic preamp is included. Also
there can be optional modules: a superphone, a line select, a second studio,
and a tape remote module. Optional modules (except second studio) can be
placed in any input slot. The optional second studio module has a dedicated
slot (see layout drawings).

HAND CRIMP TOOL WIRING INSTRUCTIONS
The supplied hand crimping tool (W/S#850067) is used for all I/O wiring con-
nections to and from the console. It is to be used with the supplied pin (figure 1)
intended for 22"-28" gauge wire.
1) Strip wire approximately 3/16" (insert in
proper wire stripper, rotate one half turn, and
pull insulation off wire).
2) Leaving wire aside for the moment, with
crimping tool fully open (engraved side toward
you) bring a terminal into position from the
unmarked side of the tool. Place the conductor
tabs (inner set as shown in figure 1) on the
"18-22" or "24-30" (depending on the wire) an-
vil (slightly curved surface) so that the circular
portion of the tabs rests in the curved surface
of the anvil and the two tabs face up into the
walls of the female jaw. The insulation tabs will
be flush with the top of the tool (figure 2).
3) Close tool very slightly, only to the point
of holding the terminal in position (figure 2).
4) Insert wire into terminal until wire insu-
lation is stopped by conductor tabs (figure 3).
CRIMP by squeezing handles until jaws are fully
closed (figure 4).
5) If there is an insertion error or if a circuit
change is needed, you'll need to use an extrac-
tor tool to remove terminals (see next page).
Note that metallized plastic hoods for each
connector are also supplied with the console.

(2) The terminal conductor tabs (pointing UP) are
placed in anvil 18-22; the terminal's insulation tabs
extend in front towards the camera.
(3) The stripped wire is placed into the terminal and
crimped. Note the wire's insulation must stop just
short of the conductor tabs (detail)
(4) Final step: jaws fully closed; the insulation tabs
have been crimped.

(5) Place extractor tip over pin terminal to be
removed.
If you accidentally insert a crimp terminal
pin into the wrong socket, you'll need to use
the supplied pin extractor tool (W/S#850069)
to remove terminal pin, and correct your mis-
take without having to sacrifice a connector.
Place extractor tip (red side) over terminal pin
to be removed (figure 5), and press it down-
wards motion until tip rests upon Housing.
Then pull out the terminal pin from Housing.
It should never be necessary to discard a con-
nector due to a wiring error.

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.
