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.

NOTE:

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.

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.

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:

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

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.

MODULE QUICK GUIDES

Pages 2-16 to 2-49 have Quick Guides to configuring each module’s logic connections and DIP switch settings. Each guide includes the audio and logic connector pinouts and signal descriptions, DIP switch setting definitions and, for some modules, logic block diagrams.

• Output 1: pages 2-46 & 2-47

• 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.

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

On = set Left

Off = set Right

On and all even numbered switches are shown set to Off.

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.

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.

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.

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.

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.

QUICK GUIDE TO THE STUDIO MODULE

Six connectors are on the optional Studio module: four 6-pin analog audio output connectors, one 14-pin studio logic connector , and one 16-pin external logic connector. All audio outputs ha ve the same audio source(s), selected using the eleven Studio source selector buttons. All connectors are hidden by the meter panel in normal operation.

AUDIO OUTPUTS

MONITOR — This 6-pin analog output connects to the amplifier for the studio or voice booth speakers. Its output level is controlled by the MONITOR LEVEL control on the module, or by a Studio Monitor Panel, PRE99-1190 with a Dual Fader Panel, PRE99-1192. The output is wired using the standard pinout sequence shown below.

HOST, CO-HOST, GUEST — These 6-pin analog outputs send audio to the headphone amplifiers for the Host, Co-Host, and/or Guest in a studio or voice booth. The Host output also has Talk to Studio audio, whereas the Guest output only has the selected Studio Monitor source audio. The CoHost output can follow the Host output or be set to only output Talk to Studio audio (SETUP switch 5 determines this setting). The outputs are wired using the standard pinout sequence shown below.

QUICK GUIDE TO THE OUTPUT 1 MODULE

There are ten connectors on the Output 1 module: five 6-pin analog audio output connectors and five 3-pin digital audio output connectors. The connectors are hidden by the meter panel in normal operation.

MIX-MINUS OUTPUTS

ANALOG — The 6-pin analog outputs have the same mono mix-minus signal applied to both outputs. The left channel also has Talk to Caller audio. The output level is fixed at a nominal +4 dBu.

DIGITAL — The 3-pin AES-3 (AES/EBU) digital outputs can individually be set for sample rates of either 48 kHz or 44.1 kHz. They have the same signals (left and right channels) as the analog outputs.

TELCO RECORD MIX

ANALOG — The 6-pin analog output is wired using the standard pinout sequence. The left channel is a mix of those Telco/Codec modules that have the TO REC function active; the right channel is the base record mix. For more information on the composition of the record mix output, see pages 3-7 through 3-9.

Operation

The operational functions for each module and

component in the Legacy console are covered in

this chapter . F or an illustration of the module place-

ment within the mainframe, see page 2-2.

Module Overview

INPUT MODULES

The Legacy has four types of input modules:

• Microphone Preamplifier

• Universal Input

• Telco/Codec (Telco), up to four

• Remote Line Selector (RLS)

One 5-input Mic Preamp is standard. A second 5-input Mic Preamp PCA can be ordered and installed into the standard Mic Preamp module. A second 5-input or 10-input Mic Preamp module can be installed directly to the right of the standard Mic Preamp.

Any combination of Universal Input modules, RLS modules, and up to four Telco modules may be installed in any of the input module positions.

Pages 3-2 through 3-14 have Quick Guides to operating the input modules:

• Mic Preamp — page 3-2

• Universal Input — pages 3-3 & 3-4

• Telco — pages 3-5 to 3-9

• RLS — page 3-10

METER SWITCHER MODULE

The Legacy has one Meter Switcher module, installed into its dedicated position in the mainframe. The Quick Guide to operating the Meter Switcher module is on page 3-11.

MONITOR MODULES

The Legacy has two types of monitor modules available:

• Control Room

• Studio

The Control Room module comes standard, installed into its dedicated position. The optional Studio module is installed directly to the right of the Control Room module. The Quick Guides to operating the monitor modules are on pages 3-12 and 3-13.

• Control Room module — pages 3-12

• Studio module — pages 3-13

OUTPUT MODULES

The Legacy has two standard output modules installed into dedicated positions on the mainframe. Their Quick Guides are on page 3-14.

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 microphone inputs (INPUTS 1 - 5).

PREAMP GAIN 6 - 10 — Gain trim controls for an optional 5-input Mic Preamp PCA (INPUTS 6 - 10).

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 and right outputs. When both L and R buttons are lit, the left and right inputs are summed into a mono mix, which then feeds both the left and right outputs.

Ro t ary Pan/ Bala nce Cont rol — When the PAN/BAL button is lit on a stereo signal, the control functions as a balance pot. On a mono signal (either L or R, or both buttons are lit), the control functions as a pan pot to position the input signal within the stereo spectrum.

PAN/ BAL — When lit, activates the pan/balance control. When unlit, adjusting the pan/ balance control does not affect the audio.

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.

Typical Telco/Codec Connection

ISDN Interface

Output 1 Module

(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.

3 Operation

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

can be selected on the Telco and its mix-minus will always be sent back to the remote, regardless of whether the module is On or Off. If a special remote broadcast mix

even if more lower priority buses are assigned on more TO REC enabled Telco modules.

Typically, only one caller is recorded at a time, but, because there can be up to four Telcos, and each module can have

those callers are feeding the left channel of the record output. When the T O REC button is “winking,” (as shown on the next page) it indicates that caller is NOT being recorded.

As with creating the F oldback Mix, the bus priority order changes when a TO REC Telco has Auto-Foldback enabled. But, there is added complexity since multiple modules can have AUTO

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.

TIMER CONTROL

This section has the controls for the event timer, located at the right end of the meter panel.

AUTO RESET — When lit, allows the timer to be automatically reset whenever an input module, with its timer reset function enabled, is turned on. When a reset command is detected, the timer resets to 00:00.0 and immediately starts counting upward. When inactive (not lit), the timer ignores module timer reset commands.

RESET — Manually resets the timer to 00:00.0. If the timer was already counting, the timer will continue to count up from 00:00.0.

HOLD — When pressed and held, stops the timer’ s display to show the elapsed time (the timer itself continues to run). Releasing HOLD returns the timer display to the current run time.

START — Immediately starts the timer from the displayed time.

STOP — Immediately stops the timer. The elapsed time remains on the

timer display until cleared by the RESET button, or START is pressed to start the timer counting up from the displayed time.

Each bar segment, from 0 down to -30, represents a 1 dB level change between bars. F rom -30 to -57, each bar represents a 3 dB difference in level.

The bars are green from -57 up to -20. The -20 level is equivalent to a 0 VU setting on a mechanical meter. W ith a properly set up console this results in a +4 dBu analog output (analog outputs can be level trimmed, however). 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 on the outputs, the red bars should rarely, if ever, light up—especially the 0 bar since this indicates the signal is at, or beyond, Full Scale Digital (the digital clipping point).

Module Servicing

Most modules consist of two assemblies: a faceplate/switchboard assembly and a Main PCA. A 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.
