Control Room Module
This module (PRE99-1318) contains the moni-
tor source selection and control facilities for the
console operator,and a co-host and a guest in the
control room.The module has parallel logic con-
trol (via a 14-pin connector) which provides ex-
ternal monitor dimming or muting, and warning
light control.The module includes four external
monitor inputs and six monitor and headphone
outputs.The outputs can simultaneously monitor
any combination of up to six analog sources (four
external inputs and Telco Record and Monitor)
andtwo digital sources (fourprograms and Send).

Universal Analog/Digital Input Module
The Universal Input modules (PRE99-1315)
feature two inputs (A and B), each of which can
acceptanalog or digital signals.Setup switcheson
the module set the source for each input. They
also set the source level (for analog signals) or the
attenuation amount (for digital signals). Each in-
put has its own fully independent parallel logic
control connector for remote control of the mod-
uleand/ormodulecontrol of the associatedsource
equipment.
Each Universal Input module includes the fol-
lowing controls or features: A/B input selection,
channel on/off control, fader level control, cue
control,mode selection with pan/balance control,
Sendcontrol,and output bus selectiontofour pro-
gram buses and one off-line bus.
Two 24-pin logic connectors connect logic wir-
ing to/from external control panels or peripher-
als. DIP switches set logic and module function
options for the A and B inputs.
Telco/Codec Input Module
Up to fourTelco/Codec (Telco) modules can be
installed into any of the input module slots on the
mainframe.The optionalTelco module (PRE99-
1316) has a single audio input (analog or digital)
from a remote send and receive device (like a tele-
phonehybrid,satellitetransceiver,ISDN interface,
or other stereo or mono Codec).
Eachmodulefeaturesmanual or automatic con-
trol of the Foldback signal returned to the hybrid
or codec.The Foldback signal for eachTelco mod-
ulecan be manually setto anyprogram oroff-line
bus.The Foldback signal can also follow theTelco
module’s on/off status when the Auto-Foldback
function is active. The Auto-Foldback function
automatically switches the feed to the caller be-
tween the off-line mix and the assigned bus with
the highest priority.For more information,see the

cantly more complete, and the related test condi-
tions are more defined, than those usually shown
for consoles in this class.Be sure to follow the test
conditions and measure in the units as stated.
The specifications arefor a fullyloaded Legacy-
30 input mainframe.
Test Conditions:
Specificationsare forthe basicsignal paths,per
channel, with >1k ohm loads connected to the
analog main outputs.
0 dBu corresponds to an amplitude of 0.775
volts RMS regardlessof the circuit impedance.This
is equivalent to 0 dBm measured into a 600 ohm
circuit for convenient level measurement with
meterscalibratedfor600ohm circuits.Noisespeci-
fications are based upon a 22 kHz measurement
bandwidth.The use of a meter with 30 kHz band-
width will result in a noise measurement increase
of approximately 1.7 dB.

MAINFRAME CONFIGURATION
The Legacy design positions the input modules
inthe physical center of the mainframe.This gives
the operator equal reach to peripheral equipment
located to the either side of the console.
ModulePlacement
The 14, 22, or 30 input module positions can
have any combination or order of the following
modules installed: Universal Input,Telco/Codec
(fourmaximum),andRemoteLineSelector(RLS).
The remaining console positionsarefixed.TheMic
Preamplifier module(s), Meter Switcher module,
Control Room module, optional Studio module,
and the two Output modules must be positioned
as shown in the illustration below.
Console Installation

level monitoring for the Program 1 and 2 out-
puts.The third meter is used to monitor the level
of Cue, Program 3 or 4, any external input, the
Send output, or the Telco Record output, as se-
lected on the Meter Switcher module.The level at
which the peak indicator (PK) comes on, as well
asthe meter displaymode (peakhold or non-peak
hold),may be set for each meter via DIP switches
on each meter display board.
The meter panel also contains a slaveable 12/
24-hour digital clock (HH:MM:SS) and an event
timer (MM:SS:T) that can be controlled manu-
ally, through buttons on the Meter Switcher mod-
ule, or automatically through module On com-
mands.
For additional information on the meter panel,
see pages 3-15 and 3-16.
CONNECTOR ACCESS
All module connectors are hidden below the
meterpanel in normal operation.Themeter panel
connects to the rear of the console by hinges.To
access the connectors, open the meter panel by
lifting it up and rotating it toward the rear of the
console until it stops.
Caution: Make sure that the panel is open all
the way so that it does not accidentally fall shut.
To facilitate initial wiring, the meter panel can
be removed from the mainframe chassis.
To removethe meterpanel from themainframe:
1Open the meter panel fully and unplug the
meterpowercable(attached to the rearpanel)
and the two cables (meter signals and talk-
back mic) from the Meter Switcher module.
2With another person holdingthemeter panel,
remove the screws and bushings that attach
each gas spring to the meter panel. Lay the
gas springs on the mainframe while working.
3Unlatchthehinges bymovingtherelease pins
to their unlocked positions and lift the meter
panel up and off the mainframe.
Toreinstall the meterpanel,alignthe two halves
of the hinges, then release the pins out of their
unlockedpositions.
Reattach each gas spring to the meter panel by
inserting a screw through the gas spring and the
bushing.

GROUNDING ANDSHIELDING
The broadcast facility’s technical ground can
be connected to the mainframe chassis using the
threaded insert on the rear of the console (shown
in the Power Connections drawing on this page).
Use a 10-32 screw and crimp lug to terminate the
facility’s technical ground wire.
Connect the cable shields at both the console
and the peripheral end when all system compo-
nents share a common ground potential and are
usingisolated groundAC outlets tied individually
back to the main technical ground.
If isolated ground AC outlets are not available,
connect the cable shields at the console end only.
The shields should be floated (left unconnected)
at the peripheral device end. Ensure the periph-
eral devices connect to a clean ground through
their power cords, or through separate ground
wires to the facility’s technical ground.
POWER SUPPLY GROUNDING
NOTE: The Power Supply chassis
connects to the AC mains safety or
“U”ground wire.
AUDIOGROUNDNOISES: Buzz pickup is gener-
ally electrostatic—such as capacitive coupling
between an audio line and a power line.To avoid
audio ground noises, do not route audio lines in
the same wireway as an AC power line.

within the console cabinetry, below and to the left
or right of the supporting countertop.The Legacy
Power Supply must be installed so that the 30
foot power supply cable supplied with the Power
Supply is not under any tension when routed
through the cabinet and connected to the
mainframe’s rear panel connectors.
ConnectingthePowerSupply
The power supply cable has two connectors:
• A 5-pin connector to supply 48 volt DC
power to the console.
• A 4-pin connector to supply power supply
statusinformation (Imminent Power Loss)
to the console.
Both connectors must be attached to the back
of the Legacy and to the power supply.
DC GROUNDING NOTE: Do not
connect
the audio or logic supply
ground wiring to the chassis of the
power supply.
AC GROUNDING NOTE: Do not
defeat the safety ground in any way.
Doing so may provide a potentially
dangerous condition to the operator.

when the console will be powered down for an
extended period.
SETTINGTHE CLOCK
The digital time-of-day clock can operate in au-
tonomous or slave modes. When used autono-
mously (the factory preset), a temperature-con-
trolled quartz crystal oscillator controls the clock
timing.In slave mode,clock timing comes from a
TC89-orTC90-compatible ESE master clock ref-
erence signal.
The operating mode (autonomous or ESE slave),
the type of ESE signal (TC89 orTC90), and the
type of clock time desired (12-hour or 24-hour
format)are set using DIP switchDS1on the clock
PCA. DS1 is on the right rear edge of the circuit
board.
To access the clock PCA,open the meter panel.
The clock PCA is mounted behind the clock dis-
play on the meter panel.
Withthe clock set toautonomous mode,it must
be set after power-up. There are three clock set
buttons on the bottom left front of the clock PCA.
• Usethe right button (Fast) toscroll bymin-
utes at a time.
• Use the middle button (Slow) to scroll by

ton to start the clock.
When an ESE time-code signal is connected to
theBNC connector onthe clock circuitboard, and
slave mode is selected (DS1-3 is set UP),the clock
does not require setting. If the ESE time-code sig-
nal fails, the clock automatically defaults to its
internal crystal reference oscillator, flashing the
display colons to indicate the loss of time-code.
EVENTTIMER
The event timer displays time in minutes, sec-
onds and tenths of seconds.The only timer option
setting is whether to display the tenths of seconds
digit as the timer runs. DS1-1 (a DIP switch on
the timer circuit board, located behind the timer
display),setswhether the tenths are shownor not.
In the UP position, the tenths of seconds are dis-
played.Inthe DOWNposition,the factory default,
the tenths do not display while the timer runs.
Note that the tenths of seconds are always shown
when the timer is in the Stop or Hold mode.

WIRE PREPARATION
All Legacy audio and logic wiring terminates
in AMP MOD IV receptacle contacts at the con-
sole.Strandedwire of 22 to 26AWG,with insula-
tion diameters of .040 to .060 inch, can be used
with the AMP MOD IV receptacle contacts.
Follow these steps for audio wire preparation:
1Stripthecableinsulationjacketandfoil shield
back 1½" [38.10 mm].
2Remove the foil shield and sleeve the drain
wire with 20 AWG Teflon sleeving. Leave
9/64" [3.57 mm] of the drain wire exposed.
3Cover the cut end of the jacket with 3/4"
[19.05mm] of heat-shrinktubing.Shrinkthis
tubing,centeredonthe jacket cut end,to hold
the drain wire sleeving in place.
4Strip the signal wire insulation back 9/64"
[3.57 mm].
5Crimp the receptacle contact onto the wire
and insulation.
Audio Cable Shield Note: To ensure your in-
stallation follows recommended grounding pro-
cedures, you must sleeve all drain wires with Te-
flon sleeving and put heat shrink tubing over all
cable jacket cut ends to insulate the shield wire.
Cabling andWiring
Before installing the console,draw up a facility
wiringplan thatlists theconsole interconnections
withallperipheraldevices.Identify and createtags
for all audio and logic cabling.List each connec-
tion in a master facility wiring logbook to facili-
tate wiring installation, future system wiring
changes,equipment updates,and system trouble-
shooting.
Refer to the module Quick Connection Guides,
on pages 2-16 to 2-49, for information on each
audio and logic connection (including block dia-
grams for each logic interface connector) and on
each module’s setup DIP switches.
REQUIREDCABLES ANDWIRE
The Legacy uses the following types of cables
and wires:
• Analog audio connections require two-
conductor, stranded, insulated, foil-shield
cable using a separate shield drain wire
(equivalentto Belden 8451,9451or8761).
• AES/EBU connections require 110 ohm
two-conductor, stranded, insulated, foil-
shield cable containing a separate shield
drain wire (equivalent to Belden 1800A).
• Logic control cables require stranded, 22
AWG, multiple-conductor, non-shielded,
jacketed cable (equivalent to Belden 9423,
8457 or 9421).The number of conductors
usedis determined bythe application.Typi-
cally cables with five and eight wires are
most often used for constructing logic
cables.Even though there are eighteen dis-
tinctsignals onthe LogicInterface connec-
tor, only a handful are typically used for
any given application.

Logic control cables are fabricated in a similar
manner to the audio wiring.Strip the jacket insu-
lation back 1½" [38.10 mm], sleeve the cut end
with 3/4" [19.05 mm] of shrink tubing and strip
the insulation from each wire 9/64" [3.57 mm].
CRIMPTOOL OPERATION
A ratcheting AMP MOD IV crimp tool is
included in the tool kit.The tool crimps both the
insulation and wire barrels on the AMP MOD IV
receptacle contacts in one crimping action.
To use the ratcheting crimp tool:
1Hold the crimp tool with the printed side up.
Insertthecontact from theoppositeside, with
the barrel openings up, until the insulation
barrel end is flush to the opening of the die.
Close the tool only until the anvil holds the
contact in place (Refer to the cutaway view
on this page).
2Insert the stripped wire into the contact until
it hits the tool’s wire stop. Hold the wire in
place while squeezing the tool handles to
crimp the contact onto the wire. The tool
handlesautomaticallyreleaseandspringopen
after the crimp cycle is complete.
Once the contact has been crimped, insert and
lock the contact receptacle into the appropriate
connectorhousing following thepin-out diagrams
found in the Quick Guides on pages 2-16 to 2-49.
A receptacle contact is inserted into the hous-
ing with its locking tab side toward the locking
tab slots on the side of the connector housing. A
slight click can be heard when the contact’s lock-
ing tab springs up into the locking tab slot.
To removeacontactfromahousing,thePRE70-
129 Contact RemovalTool (included in the PRE
76-2001 tool kit) is required. Insert the tool’s tip
into the locking tab slot and press the locking tab
down while lightly pulling on the wire to remove
the contact from the housing.
