1 General Information

Universal Analog/Digital Input Module

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).

The Control Room module features monitor and headphone fader -level controls, monitor -mode con-

trol, cue and talkback level controls, and headphone Auto-Cue select.

Studio Module

The optional Studio module (PRE99-1319) is installed to the right of the Control Room module. It provides a monitor and talkback-level control for one studio or voice booth. The monitor source can be any combination of 11 sources (four exter nal inputs, four programs, Send, and T elco Record and Monitor) simultaneously.

The Studio module has a 14-pin parallel logic connector for external dimming or muting of the studio monitor speakers and control of a studio warning light interface. Controls also provide the ability to talk to or from a studio and an external location.

Output Modules

Two Output modules ship standard with the Legacy.

The Output 1 module (PRE99-1320) contains the digital-to-analog converters and mix matrices for creating mix-minus foldbacks to support up to four Telco/Codec modules. It also contains individually mixed outputs for Telco/Codec recording. There is a mix-minus output for each Telco/ Codec module. Digital and analog outputs are provided for the mix-minus and recorder feed outputs. For digital outputs, sample rates of 48 kHz and 44.1 kHz are supported. T he mix-minus analog outputs are fixed at +4 dBu. This module features output sample rate selectors for digital outputs and a gain trim control for the analog Telco record mix output.

The Output 2 module (PRE99-1321) contains the AES digital output drivers, digital-to-analog converters, and analog line amplifiers for the Send output and the four program outputs. The digital output sample rate is 48 kHz. An output sample

rate of 44.1 kHz can be selected for the program 1 and 2 auxiliary outputs, the program 3 and 4 outputs, and the Send output. Gain trim controls for the analog outputs are also provided.

Pow er Supply

The separately packaged rack-mount power supply assembly (PRE99-1202) uses keyed connectors to supply a single +48 volts DC to the console mainframe. There are two connectors from the power supply assembly to the console: one connector supplies DC power and the other supplies electrical signal information to the console. The power supply module has an on/off switch and an LED indicator on the front panel. The power supply is fully regulated and protected against excessive current by internal fuses and electronic safeguards.

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.

Total Harmonic Distortion (THD+N) is measured at a +18 dBu output level using 1 kHz or a swept signal with a 22 kHz low-pass filter.

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.

Meter Panel

The meter panel contains three horizontal bargraph meters. T wo of the meters pro vide individual level monitoring for the Program 1 and 2 outputs. 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 selected on the Meter Switcher module. The level at which the peak indicator (PK) comes on, as well as the meter display mode (peak hold or non-peak hold), may be set for each meter via DIP s witches 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 manually , through buttons on the Meter Switcher module, or automatically through module On commands.

For additional information on the meter panel, see pages 3-15 and 3-16.

POWER SUPPLY

The power supply assembly is rack mounted (it requires 2 RU or 3.5" [88.9 mm] of rack space) 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.

Connecting the Power Supply

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 status information (Imminent Power Loss) to the console.

Both connectors must be attached to the back

of the Legacy and to the power supply.

Power Connections —

Console Mainframe, Rear Panel

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:

When an ESE time-code signal is connected to the BNC connector on the clock circuit board, and slave mode is selected (DS1-3 is set UP), the clock does not require setting. If the ESE time-code signal fails, the clock automatically defaults to its internal crystal reference oscillator, flashing the display colons to indicate the loss of time-code.

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. Note that the tenths of seconds are always shown when the timer is in the Stop or Hold mode.

Cabling and Wiring

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.

CRIMP TOOL 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:

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.

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 2 1

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).

6-pin

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.

When an unbalanced device must connect to a Legacy balanced analog output, and an IHF-PRO match box is not available, do not tie the low (-) and shield pins together to “unbalance” the signal. The low output pin must always be left “floating” when unbalancing a Legacy output, as shown in the following illustration.

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.

• Output 2: pages 2-48 & 2-49

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

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 (-) and Reset/Talk to Studio (-) are tied to logic ground on the peripheral device. Ready/Talk to External (+) and Reset/Talk to Studio (+) then connect to the appropriate logic outputs on the peripheral device.

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.

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 logic connections and settings, see pages 2-38 to 2-45.

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.

Analog Mic Inputs

OUTPUTS

1 - 10 — The 6-pin analog outputs are wired in parallel (mono) using the standard pinout sequence. This allows these outputs to connect directly to Universal Input modules without requiring any setting changes be made to the Input Mode from a standard stereo input. The preamp output signal level is +4 dBu.
