Universal Analog/Digital InputModule
The Universal Input modules (PRE99-1315)
feature two inputs (A and B), each of which can
accept analog or digital signals. Setup switches on
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 input has its own fully independent parallel logic
control connector for remote control of the module and/or module control of the associated source
equipment.
Each Universal Input module includes the following controls or features: A/B input selection,
channel on/off control, fader level control, cue
control, mode selection with pan/balance control,
Send control, and output bus selection to four program buses and one off-line bus.
Two 24-pin logic connectors connect logic wiring to/from external control panels or peripherals. DIP switches set logic and module function
options for the A and B inputs.
Telco/Codec Input Module
Up to four Telco/Codec (Telco) modules can be
installed into any of the input module slots on the
mainframe. The optional Telco module (PRE99-
1316) has a single audio input (analog or digital)
from a remote send and receive device (like a telephone hybrid, satellite transceiver , ISDN interface,
or other stereo or mono Codec).
Each module features manual or automatic control of the F oldback signal returned to the h ybrid
or codec. T he F oldback signal for each Telco module can be manually set to an y program or off-line
bus. T he F oldback signal can also follow the T elco
module’s on/off status when the Auto-Foldback
function is active. The Auto-Foldback function
automatically switches the feed to the caller between the off-line mix and the assigned bus with
the highest priority. For more information, see the
Telco Operation section on pages 3-7 to 3-9.
Each Telco module includes the following controls or features: channel on/off control, fader level
control, cue control, mode selection with pan/balance control, Send control, record and monitor
controls, and output/Foldback selection to four
program buses and one off-line bus. Logic I/O is
available for logic wiring to/from the hybrid or
codec.
Remote Line Selector (RLS)Module
This module (PRE99-1323) features two banks
of eight selection buttons to independently route
the eight input signals to the two outputs. The
module switch either analog or digital signals, as
set by a DIP switch on the module.
Meter Switcher Module
This module (PRE99-1317) is located to the
right of the input module area. It provides control
of the digital timer and contains the meter source
selector buttons and the signal drivers for all the
meter displays.
The timer control section features stop, start,
hold, and reset controls, as well as whether the
modules automatically reset the timer .
Control Room Module
This module (PRE99-1318) contains the monitor 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 control (via a 14-pin connector) which provides external 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)
and two digital sources (four programs and Send).

SPECIFICATIONS
The specifications for the Legacy are significantly more complete, and the related test conditions 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 are for a fully loaded Legacy30 input mainframe.
Test Conditions:
Specifications are for the basic signal paths, per
channel, with >1k ohm loads connected to the
analog main outputs.
0 dBu corresponds to an amplitude of 0.775
volts RMS regardless of the circuit impedance. This
is equivalent to 0 dBm measured into a 600 ohm
circuit for convenient level measurement with
meters calibrated for 600 ohm circuits. Noise specifications are based upon a 22 kHz measurement
bandwidth. T he use of a meter with 30 kHz bandwidth will result in a noise measurement increase
of approximately 1.7 dB.

Console Installation
To simplify console installation, logic cable wir ing diagrams for specific peripheral equipment are
available from the Harris Technical Services department. See page 4-1 for contact information.
INSTALLATION NOTE: Do not locate the con-
sole near intense electromagnetic hum fields, such
as those produced by large power transformers
and by audio amplifiers that use inexpensive
power transformers operating in or near saturation. Strong electromagnetic fields may impair the
performance of the Legacy and neighboring equipment. Audio cables must also be routed to achieve
maximum practical distance from all AC power
mains wiring.
Legacy Mainframe, Module Configuration
MAINFRAME CONFIGURATION
The Legacy design positions the input modules
in the physical center of the mainframe. T his gives
the operator equal reach to peripheral equipment
located to the either side of the console.
Module Placement
The 14, 22, or 30 input module positions can
have any combination or order of the following
modules installed: Universal Input, Telco/Codec
(four maximum), and Remote Line Selector (RLS).
The remaining console positions are fixed. T he Mic
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.
The number of input module positions matches the console model number (e.g., Legacy-22 has 22 input positions). There are
two DSP cards in the Legacy-14, three in the Legacy-22, and four in the Legacy-30.
The areas covered by the five 12.25" Blank Panels can be used for mounting Harris BMXdigital Accessory Panels or custom remote
control panels. Since the Harris BMXdigital Accessory Panels are 6" long, a PRE99-1100 Divider Kit (for mounting up to four
Accessory Panels in place of two 12.25" Blank Panels), or a PRE99-1101 Divider Kit (for mounting up to six Accessory Panels in place
of three 12.25" Blank Panels) is required. Typically, the PRE99-1100 Divider Kit is installed in place of the Blank Panels on the left
end of the console and the PRE99-1101 is installed in place of the Blank Panels on the right end of the console. 6" Blank Panels
(PRE99-1714-3) cover unused Accessory Panel positions.

GROUNDING AND SHIELDING
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 components share a common ground potential and are
using isolated ground AC 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 peripheral devices connect to a clean ground through
their power cords, or through separate ground
wires to the facility’s technical ground.

SETTING THE CL OCK
The digital time-of-day clock can operate in autonomous or slave modes. When used autonomously (the factory preset), a temperature-controlled quartz crystal oscillator controls the clock
timing. In slav e mode, clock timing comes from a
TC89- or TC90-compatible ESE master clock reference signal.
Master clocks are available from:

the type of ESE signal (TC89 or TC90), and the
type of clock time desired (12-hour or 24-hour
format) are set using DIP switch DS1 on the clock
PCA. DS1 is on the right rear edge of the circuit
board.

EVENT TIMER
The event timer displays time in minutes, seconds and tenths of seconds. T he 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), sets whether the tenths are shown or not.
In the UP position, the tenths of seconds are displayed. In the DO WN position, the factory default,
the tenths do not display while the timer runs.

METER SETUP
The level at which the blue peak indicators turn
on, as well as the meter display mode (peak hold
or non-peak hold), is set separately for each meter
using DIP switches on the edge of each meter PCA.
To access the meter DIP switches, open the meter
panel by lifting it up and rotating it toward the
rear of the console until it stops. Each meter ’s DIP
switches are located on the underside of the meter
panel, directly below the right end of each meter.

Before installing the console, draw up a facility
wiring plan that lists the console interconnections
with all peripheral devices. Identify and create tags
for all audio and logic cabling. List each connection in a master facility wiring logbook to facilitate wiring installation, future system wiring
changes, equipment updates, and system troubleshooting.
Refer to the module Quick Connection Guides,
on pages 2-16 to 2-49, for information on each
audio and logic connection (including block diagrams for each logic interface connector) and on
each module’s setup DIP switches.
REQUIRED CABLES AND WIRE
The Legacy uses the following types of cables
and wires:
WIRE PREPARATION
All Legacy audio and logic wiring terminates
in AMP MOD IV receptacle contacts at the console. Stranded wire of 22 to 26 A WG, with insulation diameters of .040 to .060 inch, can be used
with the AMP MOD IV receptacle contacts.
Insulation Barrel
9/64” [3.57 mm]
Wire Barrel
Properly
Crimped Contact
• Analog audio connections require twoconductor, stranded, insulated, foil-shield
cable using a separate shield drain wire
(equivalent to Belden 8451, 9451 or 8761).
• AES/EBU connections require 110 ohm
two-conductor, stranded, insulated, foilshield 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
used is determined by the application. Typically cables with five and eight wires are
most often used for constructing logic
cables. Even though there are eighteen distinct signals on the Logic Interface connector, only a handful are typically used for
any given application.
AMP MOD IV Receptacle Contacts
Follow these steps for audio wire preparation:
1 Strip the cable insulation jacket and foil shield
back 1½" [38.10 mm].
2 Remove the foil shield and sleeve the drain
wire with 20 AWG Teflon sleeving. Leave
9/64" [3.57 mm] of the drain wire exposed.
3 Cover the cut end of the jacket with 3/4"
[19.05 mm] of heat-shrink tubing. Shrink this
tubing, centered on the jacket cut end, to hold
the drain wire sleeving in place.
4 Strip the signal wire insulation back 9/64"
[3.57 mm].
5 Crimp the receptacle contact onto the wire
and insulation.
Audio Cable Shield Note: To ensure your in-
stallation follows recommended grounding procedures, you must sleeve all drain wires with Teflon sleeving and put heat shrink tubing over all
cable jacket cut ends to insulate the shield wire.

To use the ratcheting crimp tool:
1 Hold the crimp tool with the printed side up.
Insert the contact from the opposite side, 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).
2 Insert 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
handles automatically release and spring open
after the crimp cycle is complete.

A receptacle contact is inserted into the housing 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 locking tab springs up into the locking tab slot.
To remove a contact from a housing, the PRE70129 Contact Removal Tool (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

AUDIO CONNECTIONS
Audio connections take advantage of the threepins per row design of the three- and six-pin AMP
MOD IV housings. Three-pin housings are used
for balanced digital connections while six-pin
housings are used for balanced analog connections.
One important exception is the Mic Preamp module, which uses three-pin connectors for balanced
analog microphone inputs.
Pin Numbers for Analog &
Digital Audio Connectors

3-pin
connector
Pin numbering always shown from the wire insertion
end, oriented from the board operator’s perspective.
All audio wiring, when plugged into a module
connector , has this orientation:
• T he audio shields are on pins 1 and 4 (the
pins closest to the board operator).
• The audio low wires (typically the black
wires) are on pins 2 and 5 (the middle pins).
• The audio high wires (typically the red
wires) are on pins 3 and 6 (the back pins).
For stereo applications, the left channel wires
plug into the left column of pins and the right channel wires plug into the right column of pins (from
the board operator’s perspective).
When a six-pin input comes from a mono source
(such as an external microphone preamp output),
the left and right inputs should be paralleled together (pins 1 and 4 tied together, pins 2 and 5
tied together and pins 3 and 6 tied together). If
this is not done, then the module’s mode buttons
will have to be set for mono operation (see page
3-4 for L/R Mode information on the Universal
Input Module).

Analog Connections
There are no analog interstage patch points
within the Legacy input or output modules. To
use the console with a patch bay, connect the line
level outputs from the peripheral devices directly
to the patch bay. Normal these signals to the appropriate analog input modules.
Likewise, the Legacy’s analog outputs may be
routed through a patch bay normalled to standard peripherals such as analog on-air processing gear, recorders, telephone hybrids, etc.
The Mic Preamp module’ s line-level outputs (+4
dBu, nominal, balanced, mono outputs) can also
be routed through a patch bay normalled to an
input module, or to external mic processing.
When a mic processor with only a microphone
level input is used, the microphone is connected
directly to the mic processor, with the processor’s
line-level output either directly connected to an
input module (using the mono wiring pinout
shown below) or through a patch bay normalled
to an input module.

Digital Connections
Most of Legacy’s digital inputs and outputs are
wired like the Microphone Input shown above. One
exception is the RLS module, which uses 6-pin
connectors since it can be set for analog or digital
operation. When set for digital, the signals connect using pins 1, 2, and 3 of the connector.
The other modules with digital inputs or outputs; Universal Input, Telco/Codec, Output 1 and
2, use three-pin connectors like that shown abo ve.
The digital inputs accept AES-3 (AES/EBU) compatible signals and, as mentioned in the Unbalanced Connections section that follows, can also
accept S/PDIF signals in most cases.
Each digital output is an AES-3 compatible signal (nominal sample rate is 48 kHz, but some
outputs are switch selectable for 44.1 kHz) . AES3 output signals cannot connect directly to an
S/PDIF input. A signal translation interface is required to accomplish this function.

UNBALANCED CONNECTIONS
Although all analog inputs and outputs are
active and balanced, unbalanced consumer or
“semipro” equipment can be connected to the con-
sole. For best results, connect an unbalanced device through an IHF-PRO match box and keep
the unbalanced cable lengths as short as possible.
If a match box is not available, connect an unbalanced device to a Legacy input using the following illustration.

S/PDIF Signals
Digital devices with only an S/PDIF digital output can connect to a Legacy input, but only when

An unbalanced-to-balanced line transformer
can also be used to interface an S/PDIF signal.
Note 1: A signal conversion interface must be
used to connect an AES/EBU output to a S/PDIF
input.
Note 2: Some S/PDIF signals may not work with
the Legacy’s inputs, even with the additional load
resistor or a transformer , because of nonstandard
levels or protocols in the S/PDIF product.
DIGITAL CLOCK REFERENCE
The Legacy has an internal clock for sample
rate timing, with sample rate converters on each
input to synchronize/convert external digital signals to the console’s internal 48 kHz sample rate.
The console can automatically synchronize to an
external AES-3 digital reference signal (of 48 kHz,
±100 ppm only) through a 3-pin connector on the
left DSP card (the DSP cards are along the back
of the mainframe, below the meter panel).
A green LED next to the connector indicates
whether the console is using internal reference
(LED is lit), or using the external reference (LED
is off). If an external reference signal is connected,
and yet the LED is still lit, this indicates the refer ence signal is not present or is out of range.

LOGIC CONNECTIONS
Legacy modules have built-in logic I/O interfaces that can control, or be controlled by,
peripheral devices connected to the console. For
example, a CD pla yer connected to a module can
be automatically started when the module is
turned on. Then, at the end of the cut, the CD
Player logic can turn the module audio off and
control the off button illumination to indicate that
the cut has been played.
When a mic remote control panel is connected,
its On, Off, Cough, and Talkback buttons control
the module while tally outputs from the module
control the button tallies on the mic panel.
Legacy modules have the following logic connectors:
• Universal Input modules have two LOGIC
I/O connectors for controlling the devices
connected to the A and B inputs.
• Telco modules have a single LOGIC I/O
connector for controlling the device connected to the module.
• T he Meter Switcher module has three EXT
TIMER connectors for resetting studio or
producer timers, and the connectors for the
factory-installed wiring that ties the mainframe to the meter panel.
• The Control Room module has a LOGIC
connector for the warning light and talkback outputs and the remote mute and dim
inputs. A CUE CNTL connector allows external cue input control.
• T he optional Studio module has one LOGIC
connector for the studio warning light and
talkback outputs and the remote mute and
dim inputs and tally outputs. An EXTERNAL connector has the talkback commands and the audio (both to and from)
for an external location.

Pages 2-50 to 2-55 show examples of typical
logic connections to the Universal Input module
for a mic remote control panel, a CD player, and a
digital delivery system.
Note: To completely isolate the console from the
peripheral device, use only the opto-isolated control input and output connections since the Logic
Ground and Logic Supply +5VDC connections are
referenced to the console’s logic power supply and
ground.
Connect these only to isolated devices, such as
a mic control panel or other Harris Accessory
Panel. Connecting the logic ground to a nonisolated peripheral device can result in a ground
loop between the console and the peripheral
device.
UNIVERSAL INPUT LOGIC INTERF A C E
A block diagram of the Universal Input module
logic interface is shown on page 2-13. Logic outputs (shown on the right side of the illustration)
are isolated from the peripheral device by six solidstate “relays . ” T he “relay contacts” can switch logic
voltages up to 60 volts at 350 mA.
Pressing the On button generates a 220 ms contact closure from pin 5 (Start Command Pulse). A
sustained contact closure while On is available on
pin 23 (Start Command Sustained). It stays closed
as long as the module is On. Pressing the Off button generates a 220 ms closure from pin 4 (Stop
Command Pulse). These three command outputs
are tied together at pin 13 (Command Common).
Module DIP switches DS2-2 (for the A input)
and DS4-2 (for the B input), set whether a single
pulse is output when the module status changes
(Off to On, or On to Off), or if each additional
press of the On or Off buttons produces another
contact closure. The default setting (switch 2 set
to OFF) is a single contact closure. When DS2-2
or DS4-2 is set to On, then each additional press
of the On or Off button produces another 220 ms
contact closure.
T he remaining outputs; Logic Activ e/Cue Tally
[pin 15], On Tally [pin 17], and Off Tally [pin 16],
are tied together at Tally Common [pin 14]. They
present sustained logic outputs for each function.
There are six logic inputs on the left side of the
illustration: Reset/Talk to Studio, Ready/Talk to
External, On, Off, Cough, and Talk to Control
Room/Ext. Cue. T hese inputs are opto-isolated and
current limited so any logic voltage from +5 to
+40 VDC can be used.
Reset/Talk to Studio, and Ready/Talk to External have both high (+) and low (-) input pins so
that either polarity logic can be used. The other
inputs use active low logic (pull to ground) that
typically come from a mic control panel (although
On and Off could be triggered by a peripheral

Inputs) must be jumpered to the + logic voltage.
Typically this is pin 6 (Logic Supply +5 VDC), but
it can also be supplied by the peripheral device.
The Reset/Talk to Studio and Ready/Talk to
External inputs can use either active low logic (pull
to ground) or active high logic (pull to +VDC) from
peripheral devices. Which function is active is determined by the setting of DS1/DS3 s witches 2, 3,
and 5. When all are off, the module is set as a
Line Input, and the commands are Reset and
Ready. When DS1/DS3 switch 2, 3, or 5 is on,
then the module is set as a Mic Input and the commands are Talk to Studio and Talk to External.
With active high logic, Ready/Talk to External

Pin 15’s signal (Logic Active Tally / Cue Tally)
changes depending upon whether the channel logic
switches (DS1/DS3) are set to mute any location.
When a mute is set (DS1/DS3, switch 2, 3, or 5 is
set to On), the module is set as a microphone and
the Logic Active Tally output (pin 15) is closed
when that input (input A for DS1 or input B for
DS3) is active. When no mute is set, the module is
set for line logic and pin 15 becomes a Cue Tally.
Setting DIP Switches
When referring to a module’s DIP switch setting, a switch is Set to Off when it is to the right
and it is Set to On when it is to
the left (orientation is from the
board operator’s perspective).
In the illustration, all odd numbered switches are shown set to

Universal Input Module Logic
and Microphones
The three main functions of microphone logic
are to automatically mute the monitor speakers
in the room with the “hot” mic, to command the
appropriate hot mic warning light, and to activate such microphone functions as talk to control
room and cough.
The warning commands come from the Control
Room or Studio modules, but it is DS1 (for the A
input) and DS3 (for the B input), switches 2, 3, or
5, on each Universal Input module that tell the
monitor modules whether a mic is located in the
control room, a studio, or an external location.
Pages 2-50 and 2-51 summarize setting up a
Universal Input module as a microphone input,
utilizing a PRE99-1198 Mic Panel (simplified
schematic shown below).
The Mic P anel connects to the module’ s LOGIC
I/O connector. To enable the remote control
inputs (On, Off , Cough, Talk to C/R), pin 18 (Activate Logic Inputs) has to be jumpered to pin 6,
10, 11, or 12 (Logic Supply +5VDC).
T he On Tally output drives the LEDs in the On
button and the Off Tally drives the LEDs in the
Off button. The other LEDs (Cough and Talkback)
connect internally to the Logic Supply +5 VDC.

All LEDs are tied to Logic Ground (pins 1, 2 or 3
on the LOGIC I/O connector).
To construct a custom mic control panel like
that shown on this page, use SPST (single pole,
single throw) momentary contact switches with
LED or lamp indicators. Lamps must be 6.3 v olt
type with a current draw of under 50 mA.
Tie one side of each switch and lamp to Logic
Common (pin 1, 2 or 3 on the LOGIC I/O connector). The other side of the Cough and Talkback
lamps tie together to Logic Active T ally (pin 15).
Each switch is tied to its logic counterpart (the
On switch goes to the On (-) input, pin 7, the Off
switch goes to Off (-) input, pin 8, etc.). T he on/off
lamps are tied to their Tally outputs (On lamp to
On Tally, pin 17; Off lamp to Off Tally, pin 16).
Tally Common (pin 14) is jumpered to Logic
Supply +5VDC (pin 6, 10, 11 or 12) at the LOGIC
I/O connector. Pin 18, Activate Logic Inputs (+)
is also jumpered to Logic Supply +5VDC (typically pin 6 is used).
Input Module Logic (Universal Input and
T elc o ) and Per ipheral De vices
Peripheral devices are controlled through the
Start and Stop Command Pulses, or through the
Start Command Sustained logic, and the Commands Common connections.
In the basic logic connection example on pages
2-52 and 2-53, activ e low logic is used, thus Command Common is connected to the logic ground
on the peripheral device (labeled Command Common on the Denon CD player in the example).
In the complex logic example shown on pages
2-54 and 2-55, active high logic is used, thus
Command Common connects to Logic Supply
+5 VDC.
Note: This voltage is more typically supplied
directly by the peripheral device in order to
prevent ground loops.

Peripheral devices control the module through
the Reset and Ready logic inputs. In the example
on pages 2-52 and 2-53, only the Ready function
is used. The Ready function performs an audio
reset, which turns off the module without generating a Stop Command Pulse. In addition, it also
controls the Off lamp illumination.
In the example on pages 2-54 and 2-55,
Reset (+) and Ready (+) connect to Logic Supply
+5VDC on the module. The Ready (-) command
and the Reset (-) command are pulled low by the
active low logic relay outputs on the peripheral
device, which all tie to the module’ s Logic Ground
(pin 1).
For peripheral devices that require a stead y on
signal, the Start Command Sustained output can
be used.
Additional Logic Connections
There are additional logic connections on the
Meter Switcher module, Control Room module,
and optional Studio module
Three 3-pin connectors on the Meter Switcher
module interface remote timers so they can be
reset by the console timer reset logic. The Meter
Switcher module also has factory-installed cabling
for the timer, the talkback mic, and the digital
level meters. For more information on the Meter
Switcher module’s logic connections and settings,
see pages 2-28 to 2-30.
A 14-pin connector on the Control Room module carries the logic interface for the Control Room
warning light, remote mute and dim inputs, and
the mute, dim and talkback tallies. The 8-pin Cue
Cntl connector on the Control Room module has
the External Cue logic interface. For more information on the Control Room module’s logic connections and settings, see pages 2-32 to 2-36.
The optional Studio module includes a 14-pin
connector to control the studio’s logic, including
warning lights, mutes, and dims. The Studio mod-
ule also has a 16-pin connector for the audio and
logic for an external site’s talkback audio and control. F or more information on the Studio module’ s

QUICK GUIDE TO THE MICROPHONE PREAMPLIFIER MODULE
Each Legacy Preamplifier module can contain two separate PCAs with five mic preamps on each
assembly. The console comes standard with one Preamp module with one five-input mic preamp PCA
that allows an additional five-input preamp PCA to be retrofitted. A second Mic Preamp (with either
five or ten inputs) can be added to the console.
Each Mic Preamp PCA has five 3-pin analog microphone input connectors and five 6-pin analog
audio output connectors. Each input connects to a separate mic preamp driving its own line-level
balanced analog output connector. The connectors are hidden by the meter panel in normal operation
and the trimpots, visible to the operator, are covered by a security cover.
INPUTS
1 - 10 — The 3-pin analog inputs accept mono microphone signals.
Connect only low impedance, balanced, dynamic or condenser
microphones, with nominal mic output levels of -65 to -30 dBu, to these
inputs.

UNIVERSAL INPUT MODULE — LOGIC I/O
There are two 24-pin logic interface connectors
on the Universal Input module. The left logic connector controls the device attached to the A input;
the right logic connector controls the device attached
to the B input. The logic connectors are hidden by
the meter panel in normal operation. Pages 2-50 to
2-55 show several connection examples.
Note that the Ready and Reset commands are
balanced inputs (they have both a + and - input),
thus for a switch input the + input has to be tied to
Logic Supply +5VDC and the switch tied to Logic
Ground.
Outputs marked with an * are only available when
the module has a Rev. C or later SPROM (21-227-
7). When DS1 (for input A) or DS3 (for input B)
switches 2, 3, or 5 are set to on, then the MIC logic
function is enabled. When switches 2, 3, and 5 are
set to off, then the Line logic function is enabled.

FUNCTIONAL DESCRIPTION
Equivalent to a Normally Open (N/O) contact. A momentary “contact closure” of 220 ms to Command Common
occurs when the module On button is pressed. Typically connects to the Remote Start logic input on the
peripheral device. When DS2/DS4-2 is set to On, each press of the On button generates another contact closure.
Same as the Start Command Pulse, except it is initiated by the module Off button. Typically connects to the
Remote Stop or Pause logic input on the peripheral device.
A maintain ed contact closure wit h Co mm a nd Com m on for a s l on g a s t h e m odu le is on . Typically conne ct s to t he
Remote Start logic input on a peripheral device that cannot use a start pulse.
The Common (C) relay contact output for the three Start and Stop Command outputs. Sets whether the Start
and Stop Commands are active high (connect this pin to the logic supply voltage on the peripheral device) or
active low (connect this pin to logic ground on the peripheral device).
To enable the control inputs: On, Off, Cough, Talk/Ext Cue, tie thi s p in to + log ic vo lt ag e (+ 5 to + 40 ) . When tied to
an isolated device like a mic remote panel, use the Logic Supply +5VDC (jumper pin 18 to pin 6, 10, 11 or 12).
When pulled low, turns the module on from off, generating a Start Pulse if DS2/DS4-3 is set to On. It is ignored if
the module is already on, unless DS2/DS4-2 is set On (then each On button press generates a Start Pulse).
When pulled low, turns the module off from on, generating a Stop Pulse if DS2/DS4-3 is set to On. It is ignored if
the module is already off, unless DS2/DS4-2 is set On (then each Off button press generates a Stop Pulse).
When pulled low, mutes the audio from all assigned buses, for as long as the Cough button is pressed.
When pulled low, and the module is set as a Mic, the input audio is muted from all output buses and only routed
to the C/R talkback bus. When set as a Line, routes the input audio to the Cue bus while the input is low.
All Tally outputs are N/O “dr y contact” type outputs. Typically used to drive indicators, the outputs can sink or
source up to 60 volts at 350 mA. The “C” or common contact for all the tallies is Tally Common (pin 14).
This output connects to Tally Common while the module is off when DS1/DS3-8 is set to On. When DS1/DS3-8 is
set to Off, then this output is controlled by the Ready logic.

This output connects to Tally Common while the module is on.
This output connects to Tally Common when the module is set as a Mic and the matching A or B input is
selected. When set as a Line input, the output is connected to Tally Common while Cue is active.
The Common (“C”) contact for the three tally outputs, it must be tied high or low to provide the return path for
the tallies. Typically, the tally lamps/LEDs are all tied to ground and Tally Common connects to the lamp supply
voltage (+5 to +60 VDC). If the tallies are tied to +VDC, then this pin would tie to ground.
These complementary logic inputs require +5 to +40 VDC between the (+) input and the (-) input for activation.
This can be done by connecting an active high logic to the (+) input and grounding the (-) input, or by supplying
+5 to +40 VDC to the (+) input and an active low logic (like a switch to ground) to the (-) input.
This function is active when the module is set as a Line Input (DS1/DS3 switches 2, 3, & 5 are all off). When
activated while the module is on, turns the module off without generating a stop pulse. When activated while
the module is off, it controls the Off LED to indicate device status. Typically, LED off indicates the peripheral is not
ready to play, a steady on LED indicates the device is ready, and a flashing LED indicates the device has already
played or is not yet cued up.
This function is active when a module is set as a Line Input (DS1/DS3 switches 2, 3, & 5 are all off). When

Typically connec t s to the Remote Start log i c i n p u t o n a peripheral device that ca n no t u se p u l se s.
The Common (C) contact output for the Start and Stop commands. For an active high logic on the command
outputs, connec t Command Common to the logic supply voltage on the peripheral device. For an active low
logic on the command outputs, connec t this pin to logic ground on the peripheral device.
Connecting +5 to +40 VDC to this input enables the active low ext ernal control inputs (On, Off, Cough, Talkback).
If the control inputs are isolated from other devices (e.g., on a control panel), the +VDC can come from +5 Lo gic.
When pulled low, turns the module On from O ff. Input is ignored if the module is already on.
When pulled low, turns the module Off from On. Input is ignored if the module is already off.
When pulled low, the module audio is muted from all assigned buses.

The Tally outputs are N/O “dry contac t ” outputs. Typically used to drive indicator lamps or LEDs, the outputs can
sink or source up to 60 volts or 350 mA. The “C ” contact for all the tally outputs is Tally Common.
While the module is off, the Off Tally output connects to Tally Common—if Ready (DS1/DS3-1) is set to On. When
DS1/DS3-1 is set to Off, then the Off Tally is controlled by the Ready input logic.
While the module is on, the On Tally output connects to Tally C ommon.
While the Talk to Caller input is pulled low, the Talk Tally output connects to Tally Common.
The “C” relay contact for the Off, On, and Talk tallies. Typically, the tally lamps/LEDs are tied together to ground
and Tally Common connects to the lamp supply voltage (up to 60 volts). If the tallies use +6.3 volt, 40 mA lamps,
and are isolated from peripheral devices (as in a remote mic control panel), then the Tally Common can come
from Logic Supply +5 Logic.
These complementary logic inputs require +5 to +40 VDC between the (+) input and the (-) input for activation.
This can be done by connecting an active high logic to the (+) input and grounding the (-) input, or by supplying
+5 to +40 VDC to the (+) input and an active low logic to the (-) input.
When activated while the module is on, the module turns off without generating a stop pulse. While the module
is off, the Ready logic controls the Off L ED to indicate device status. Typically, LED off indicates the peripheral is
not ready to play, LED on indicates the device is ready, and a flashing LED indicates the device has already played
or has not been cued up.
When activated while the module is on, turns the module off without generating a stop pulse. Input is ignored if
the module is already off.

CONTROL ROOM MODULE — LOGIC
The 14-pin Logic connector has the warning
light output “relay,” the remote mute and dim
control inputs, and three indicator outputs (talkback, dim, mute).
Pins 4 and 5 offer an isolated contact pair
for triggering an external warning lamp interface.
To use the remote inputs (Dim, on pin 9; Mute
on pin 8), pin 14 (Activate Logic Inputs) must
be tied to Logic Supply +5VDC (pin 6 or 7), or
if an external device rather than a switch is
activating these inputs, then this voltage should
come from the external device to keep the console isolated.

MICROPHONE PREAMPLIFIER MODULE QUICK GUIDE
This module amplifies up to ten low-level microphone signals to line-level. The
module comes standard with five mic preamps, with an additional 5-input Mic Preamp
PCA (PRE95-1151-2) available as an option to the standard Mic Preamp module. A
second Mic Preamp module can also be ordered. Use PRE99-1151-1 to order a 10input Mic Preamp module or PRE99-1151-2 to order a 5-input Mic Preamp module.
The +4 dBu mono output from each preamplifier can be jumpered directly to a
Universal Input module, routed to a patch bay, or connected to an external line-level
signal processor .
DIP switches (hidden by the meter panel) switch phantom power to an y input. Gain
trim controls set the preamp gain as required for the application. These are normally
set once during installation and then covered by a security panel.
MIC PREAMPS
This module section has the trim controls for setting the nominal
output to +4 dBu for each microphone. The nominal input signal
levels can range from -65 dBu up to -30 dBu
PREAMP GAIN 1 - 5 — Gain trim controls for the five standard

UNIVERSAL INPUT MODULE QUICK GUIDE
This module has two inputs, each with analog and digital inputs. The source used, as well as other
module set-up functions, is set by DIP switches . T wo logic connectors allow individual control of the
connected devices, with talkback functions for modules set as mic inputs. Every Universal Input
module can be assigned to any combination of four Program buses, one Send, and one off-line bus.
F ADER SECTION
This section has the module On, Off, and Cue buttons, the input select controls, and the fader .
The 2.0" x 0.5" area to the left of the A in, B in, and FCN buttons is available for labelling the
A and B inputs. The protective lens can be removed, using the PRE70-90 Hex Driver (included
with the tool kit) so that a label can be placed under the lens..
A IN — Used along with the
FCN
button to select the A Input. The button is lit when the A
input is selected.
FCN — Protects the input selector buttons from accidental changes. To change the input
source,
FCN
must be pressed and held for about one second (until the
up). This activates the
A in
and
B in
buttons so the input can be changed. The
FCN
button lights
FCN
button
automatically turns off after about three seconds.
B IN — Used along with the
FCN
button to select the B Input. The button is lit when the B
input is selected.
FAD ER — 100 mm module level control. Setting the fader at the red reference line
(-12 dB) sets the module for unity gain.
CUE — When lit, routes the input audio to the Cue output. This does not affect the on-line
signal. The cue audio is always pre-switch and pre-fader. When the module is used with a
microphone, the cue function is momentary. When the module is not a mic input, the cue
button toggles the cue function on and off.
ON — Press to turn the module on, applying the module’s audio to the selected buses.
Pressing this button also initiates logic control commands (such as Start Pulse, Mute, Timer
Reset, On T ally , etc.), depending upon the Setup DIP switch settings. This button is lit whenever
the module is on.
OFF — Press to turn the module off, removing the module’ s audio from all selected Program
buses (and the Send if set for post-switch). Pressing this button also initiates logic control
commands (such as Stop Pulse, Off Tally , etc.), depending upon the Setup DIP switch settings.
The button illumination may be controlled by an external device to indicate its ready status.

3 Operation
Universal Input Module (continued)
SEND
This section has the level, on/off control, and signal routing controls to feed the module’s audio to
the Send bus.
PRE FADER — When lit, the Send audio feed is taken before the module fader (thus
adjusting the fader level does not affect the Send output level). When unlit, the Send level is
affected by the module fader setting.
PRE SWITCH — When lit, the Send audio is always active (it is not affected by the module
On/Off buttons). When unlit, the Send audio feed follows the module on/off status.
Rotary Volume Control — Sets the level of the module audio feeding the Send bus.
ON/OFF — When lit, connects the module to the Send bus. If the module is on (or if the
PRE SWITCH button is lit) and the rotary volume control is turned up (and the module
fader is up, if PRE FADER is not lit), then audio is applied to the Send bus. When unlit, no
audio from this module is applied to the Send bus.
PROGRAM BUSES
This section has four Program and one off-line bus selectors.
PGM 1, PGM 2, PGM 3, PGM 4 — When lit, routes the module audio to any
combination of the Program 1, Program 2, Program 3, and Program 4 buses. When unlit,
the module audio does not feed that bus. These outputs are always post-switch and postfader.
OFF LINE (O/L) — When lit, routes the module audio to the Off-Line bus (which is used
to build up an off-air mix-minus for the Telco/Codec outputs). The Off-Line feed is always
pre-switch, but whether it is pre-fader or post-fader is set for all Inputs by a DIP switch on the
Meter Switcher module. For details on setting this option, see page 2-29.
MODE/PAN/BAL
This section has the controls for setting the module’s mode (stereo or three mono modes) and the
pan or balance of the module’s bus outputs.
L & R — These buttons set the mode (stereo or mono). When both buttons are unlit, the
module is stereo input/stereo output. When the L (left) button is lit, the left input feeds both
the left and right outputs. When the R (right) button is lit, the right input feeds both the left

TELCO/CODEC MODULE QUICK GUIDE
Up to four Telco modules may be installed into any input module position in the
mainframe. The module has a single input (analog or digital). DIP switches set the
input source and other module functions, such as the Telco ID number for the module. A logic connector allows control of the connected device. Telco modules can be
assigned to any of the four program, Send, Off-Line, T elco Record, and Telco Monitor
buses. T ext on using the Telco module’s special functions follows on pages 3-7 to 3-9.
SEND
This section has the same controls and functions as the Universal Input module.
See page 3-4 for functions.
PROGRAM BUSES
This section allows the four main outputs and one off-line output to be selected.
It also sets manual or automatic foldback.
3 Operation
PGM 1 - 4 — Assigns the module to any combination of the Program 1,
Program 2, Program 3, and Program 4 buses. When the module is
assigned to a bus, the associated button is lit. A “winking” button indicates
the bus output being used as the Foldback Mix.
OFFLINE (O/L) — The off-line bus is used for building up off-air mixminuses. The Telco module feed to this bus is always pre-switch but postfader . When assigned to this bus, the O/L button lights. A “winking” button
indicates the output that’s being used as the Foldback Mix.
AU TO — When lit, automatically switches the foldback mix between a
program bus (when the module is on) and the off-line bus (when the
module is off). When unlit, the foldback mix is not affected by the module
on/off status. For more information on the Foldback Mix and using the
Auto button, see pages 3-7 to 3-9.

TELCO/CODEC MODULE OPERATION
Up to four “callers” (any remote send/receive
device like a telephone hybrid, satellite transceiver ,
ISDN interface, etc.) can connect to their own T elco
modules, as shown below.
Each Telco module must be set to a unique T elco
ID number (see page 2-23) to create a unique mixminus output on the Output 1 module. The mixminus outputs, also called foldback mixes, send
one of the program or off-line buses back to the
callers—but always minus that caller’s audio.
Hence the mix-minus nomenclature, and why
there are four foldback outputs on Output 1.

(set as Telco #1)
NOTE: The off-line bus is pre-s witch and post-fader
on the Telco modules. The Universal Inputs are
pre-switch, but they may be pre-fader or post-fader ,
as set for all modules by Meter Switcher module
DIP switch 6 (see page 2-29).
The bus used for the foldback mix is determined
from the buses assigned and whether Auto-Foldback is on, and if it is , then the Telco’s state (module On or Off) affects which bus is selected.
Auto-Foldback On
When the AUTO button is lit, as shown below,
that Telco’s foldback mix automatically switches
between an assigned program bus when the module is On, and the off-line bus when the module is
Off, using this bus priority:
While the Module is On, Program 1 is the
foldback mix source. If it’ s not assigned, then the
source is selected in this order; Program 2, Program 3, Program 4, Off-Line.
While the Module is Off, Off-Line is the primary
foldback mix. If it’ s not assigned, there will be no
mix-minus audio (except for any talkback on the
left channel output).
Each mix-minus output has two channels.
The left channel is for the caller, remote talent, or a remote producer since it can have
talkback superimposed onto the mix-minus
audio. The right channel is a “clean feed” (it
has no talkback). It can be used for guests
or a remote site broadcast feed. The board
operator can talk to any caller (using the talkback mic in the console), by connecting an external Talk to Caller switch to the Telco module logic
connector. One SPST momentary switch would
be required for each caller.
FOLDBACK MIX
The foldback mix source, indicated b y a “winking” bus assignment button, can be any program
or the off-line bus.

Auto-Foldback On is the most common setting
for call-in contests or interviews where the caller
will go live on-air. Typically, only the talent’s mic
module and the caller’ s Telco module are assigned
to the Offline (O/L) bus. With the Telco module
Off, the caller can hear the talent thru the offline
bus, and the talent can hear the caller through
either the Telco Monitor output or Cue. When the
Telco module is turned on, the mix-minus feed is
switched to Program 1 (assuming the air feed is
Program 1), so the caller now hears everything
going to air—minus their own voice.
TELC O RECORD MIX
A two-channel Telco Record Mix output is available in analog and digital format on the Output 1
module.
The left channel has only the callers from the
Telco modules that have their T O REC buttons lit
solid (see page 3-6 for more info on this button).
The right channel has a base mix (one program
or the off-line bus). The source for the base mix is
determined by a bus priority order , similar to how
the Foldback Mix source is selected. Again, the
highest priority bus assigned on any TO REC enabled Telco becomes the source for the base mix—
Auto-Foldback Off
When Auto-Foldback is off (the AUTO button
is not lit), the module uses a different bus priority
order.
While the Module is On or Off, the primary
foldback source is Off-Line. If it is not assigned
then the program buses are selected in this order;
Program 1, Program 2, Program 3, Program 4.
Auto-F oldback Off is the most common setting
for recording callers for later broadcast and for
doing a live remote where a “broadcast” feed to
the remote site is required. In
a remote broadcast, when the
remote talent goes on-air , the
mix-minus should not
change, thus only Program 1

turned On! Thus , the easiest wa y to record a caller
is to keep AUTO turned off and only have one
Telco module with T O REC active.
Here are the two Telco Recording priority
orders and what happens in each condition:
AUTO is un-lit on all TO REC Telcos: T he Base
Mix source is Off-Line and the TO REC Telco module On/Off settings do not affect the record output (as shown on the previous page). It is the easiest method to record callers.
If Off-Line is not assigned, then the Program
buses are used in order; Program 1, Program 2,
Program 3, Program 4. In this case the TO REC
Telco module must be turned On to record the
caller . If the TO REC module is Off, then TO REC
will wink, indicating that caller is NOT feeding
the Telco Record output.
AUTO is lit on at least one TO REC Telco: In this
case, the base mix source is affected by the On/
Off state of any TO REC Telco with its AUTO
button lit. When all of the Telcos with AUTO lit
are On, then Program 1 is the primary base mix
(followed by Program 2, Program 3, Program 4,
Off-Line).
When any of these modules are Off, then OffLine becomes the base mix. If it’s not assigned,
there will be no callers recorded and all the TO
REC buttons will be winking. This is summarized
in the illustration on this page.

From -20 up to -3 the LEDs are yellow. Levels should normally peak in this area.
The 0, -1, and -2 bars are red to indicate the signal is dangerously close to clipping . To prevent digital distortion

third assembly may be used to add additional connectors. Assemblies may be replaced in the field,
but none are field-serviceable.
Note: Do not disassemble the faceplate/switchboard assembly.
Any module that is not currently in the console’s
signal path, except for the DSP modules and Output 2, can be removed and installed with the console powered on, and on-air, without causing audio interruption or noises in the program audio.
It is best to first unassign all bus assignment
buttons and then unplug all input, output, and
logic cables before removing a module from the
console.
Removing Modules
To remove a module from the mainframe:
1 Open the meter panel.
2 Use the included hex tool (PRE 70-90) to re-
move the two screws located at the top and
***
bottom of the module.
3 Use the hex tool to remove the grounding
screw located directly below the DIP switches.
4 Screw the module pull tool (PRE 70-43) into
the grounding screw hole and use the tool to
carefully lift the module out of the mainframe.

Note: If you need to replace one of the assemblies,
contact Harris Technical Services for further instructions.
Installing Modules
To install a module into the mainframe:
1 Open the meter panel.
2 Remove the blank panel, if installed, then
lower the module into its slot. Be sure to align
the pins on the PCA with the motherboard
connector in the mainframe.
3 When the pins are aligned, press straight
down to seat the module. Do not force the
module, and do not press on buttons or connectors while seating the module.
Note: If the module does not work after installa-
tion, remove the module. Visually check to make
sure that no connector pins are bent, then reinstall the module.
FADER SERVICING
There are no replaceable or rebuildable parts
on the Legacy fader assembly . F ader service is comprised of cleaning and lubricating. Faders are conductive plastic, single-element faders.
If the fader movement is rough, either the lubricant on the glide rails has evaporated or foreign
material has gotten into the fader. Dow Corning
510 is the preferred glide rail lubricant as it will
not migrate to the contact fingers like other lubricating oils.
Fader Disassembly and Cleaning
To disassemble and clean faders:
1 Remove the module from the mainframe.
2 Remove the fader knob and the two fader
mounting screws, then remo ve the fader from
the switch assembly.
3 Remove the snap-on fader assembly cover. It
is held in place by plastic tabs.
4 Clean the fader using either a dry cotton swab
or a cotton swab dampened with distilled
water .
Note: The use of chemical cleaners on the conductive plastic will substantially shorten fader life.
Never touch the fader slider contact fingers while
cleaning the fader parts.
Use only a dry cotton swab, or a cotton swab
dampened with distilled water, to clean the fader
parts. Always use a clean dry swab to dry off the
conductive plastic tracks after cleaning. If the fader
rails are noticeably dirty, wipe them off using a
dry cotton swab before lightly lubricating the top
rail with Dow Corning 510 lubricant (or equivalent).
If coffee, a soft drink, or other sugared liquid
has been spilled into the fader , remo ve it from the
module as soon as possible and remove the top
cover of the fader. Hold the fader under hot running water and move the fader slider back and
forth to dissolve the sugars and other chemicals.
Thoroughly dry the rails and conductive plastic
using dry cotton swabs and then lubricate the top
fader rail with Dow Corning 510 lubricant (or
equivalent).
Lubricating the Glide Rail
Move the fader slider to the middle of its travel
and place one drop of Dow Corning 510 lubricant
(or equivalent) on the top rail on either side of the
fader slider bushings. Mov e the slider through its
full travel to distribute the lubricant. Be sure to
wipe off any excess lubricant. Normally only the
top rail (the one on which the fader slider bushings glide) requires lubricant.

CLOCK AND EVENT TIMER
The Clock and Event Timer assemblies are
mounted in the meter panel.
Clock T roubleshooting
If the clock is not working properly , check that
the supply cable leading to the assembly is installed
correctly. Also check the DIP switches that control the clock’s operating mode. The clock’s DIP
switches are at the edge of the clock circuit board.
For more information about the clock circuit board
switches and settings, see page 2-5.
Event Timer T roubleshooting
If the Event Timer is not working properly,
check that the cable leading to the assembly is
installed correctly . It plugs into the Meter Switcher
module.
If the tenths of seconds display is not functioning as expected, check the DIP switch on the Ev ent
Timer circuit board. For more information about
the Event Timer, see page 2-6.
If the Event Timer is not automatically resetting as expected, check the input modules’ DIP
switches to make sure the Timer Reset switch is
set correctly. For more information about setting
the input module DIP switches, see page 2-19.
POWER SUPPLY
Periodically check that the vent openings on the
power supply chassis are not blocked and that
there is no dust buildup on the vent openings.
Caution: To reduce the risk of electric shock, do not open the power
supply . Refer servicing to qualified
service personnel only.
Pow er Supply C onnections
The power supply cable has two connectors:
• T he 5-pin connector supplies DC power to
the console.
• T he 4-pin connector supplies an Imminent
power shutdown warning to the console.
Both connectors must be attached to the back
of the Legacy and to the power supply. See page
2-4 for additional information about the power
supply connections.

BACKUP BATTERIES
A “K eep Alive” voltage is generated by three AA
nickel cadmium (NiCad) batteries (PRE 50-7),
supplied in the tool kit. These batteries supply a
voltage that holds each module’s logic state during momentary power outages. This ensures that
the console powers back up in the same state it
was in when power was lost.
These batteries should be replaced yearly to
ensure continuous backup protection. Additional
battery information is given on pages 2-4 & 2-5.

GENERAL TROUBLESHOOTING TIPS
Five converter boards (four on the Legacy-14)
are on the Power Stick assembly mounted to the
rear chassis. Each converter board is protected b y
a solder-in fuse. A red LED on each board indicates it is working (remove the bottom cover panels to observe these LEDs). The boards convert
the +48 VDC input into +/-19, +5, and +3.3 volts .
A power flow block diagram is shown below.
The console will not function without the Master and Slave DSPs and Output 2 installed. These
modules generate several clock signals that coordinate communications between the console modules. If these are clocks are missing there will be
no module activity (no button LEDs, no meter displays, etc.). No other modules (Input, C/R, Session, etc.) are absolutely essential to “starting up”
the console.
The green LED on the power supply indicates
its 48 volt output is good. Red LEDs on the DSP
cards indicate they are powered. If the power supply is good, and yet the only lights on the console
are the LEDs on the DSP cards and the dB and
channel lights on the meters, then check the Imminent Power Loss signal (as previously shown
in the Power Supply section). With the power supply on, pins 1 & 2 are shorted (and pins 3 & 4 as
well if a secondary supply is used). If this signal
opens up, it tells the console the power supply has
lost power. This causes the modules to save their
current button settings before the supply voltage
is lost (large supply capacitors keep things powered up for a very short time). Pins 1 & 2 can be
manually shorted at the mainframe 4-pin connector to see if this signal is the cause of a start-up
problem.
