Installation and Power

Unpacking the Console

The A-2000 console is shipped as two packages. One carton contains the console and documentation and the second carton contains the Power

Supply and connecting cable.

Countertop Mounting

The A-2000 audio console is designed for countertop mounting.

Console placement should avoid proximity to any electromagnetic fields, such as large power transformers, motors, and fluorescent lighting fixtures. If you will be securing the console to the counter top, you may want to pre-drill the mounting holes (see sketch below).

Set the console in place on the counter, and remove the screws that hold down the first and the last modules in place (two per module).

Carefully remove those modules from the frame. Attach the console mainframe to the counter top, using the holes provided in the bottom of the chassis and screws appropriate to the counter material, and reinstall the removed modules.

The console extends approximately 7 5/8” above the countertop at the meterbridge. The hinged meterbridge will require 14” above the countertop surface and 4 3/4” behind the rear meterbridge to open freely.

Do not connect the A-2000 console to its power supply (and do not connect the power supply to the AC power line) until instructed to do so.

System Ground

The first step is to ground the console.

Note that as supplied from the factory, console rackmount power supply common, audio ground, and the A-2000 mainframe are connected together at the console, but are NOT connected to electrical ground and the chassis of the power supply. Safety requirements dictate that a positive connection from the console mainframe to electrical ground be made in the completed installation. Use the grounding lug on the rear of the mainframe to establish your system ground. The grounding lug may be found at the rear of the console, on the rear frame panel, to the left if you are looking at the rear of the console.

The system ground serves two important purposes:

(1) It provides a zero signal reference point for the entire audio system;

(2) It assures safety from electrical shock.

There exist two terms that one encounters in a discussion of ground:

(A) EARTH GROUND, which is usually a heavy copper rod driven into the soil adjacent to the building (around 6 feet down) or a connection to the copper water pipes leading into the building. Either is acceptable (unless, of course, the water pipe is made of plastic).

GROUNDING SCHEME

Tie the console ground lug terminal strip to the system earth ground. Tie every piece of equipment in the entire audio system to the console ground lug terminal strip.

(B) THE POWER COMPANY EARTH CONDUCTOR that enters the building at the power line breaker box; this conductor should be (and is often by code) tied to the above-mentioned earth ground at one point. This point is the SYSTEM

EARTH GROUND.

TIE THE CONSOLE GROUND LUG TO THE SYSTEM EARTH

GROUND. TIE EVERY PIECE OF EQUIPMENT IN THE ENTIRE

AUDIO SYSTEM TO THE CONSOLE GROUND LUG. If the system earth ground point is inaccessible, tie the console ground lug to the power company earth conductor at the main breaker box (see drawing "Typical

Grounding Scheme" on previous page).

Each piece of equipment should be connected by its own ground wire

(usually the round third pin on the AC cord). This means that every AC outlet must have a separate conductor run to the console ground lug; the outlets cannot be daisy-chained as is normally encountered in commercial and residential AC systems. Any equipment not supplied with 3-wire AC cables must have individual ground wires (16 gauge or larger) connected to their chassis grounds and then run to the console ground lug terminal strip.

Further Grounding Details

Check all equipment to be absolutely certain that each unit is power transformer isolated from the AC mains to prevent safety hazards.

It is assumed that in each piece of audio equipment the audio ground and the chassis are tied together at some point. Any piece of equipment lacking a grounded chassis is likely to be prone to interference problems.

Locate all unbalanced audio equipment in the same rack if possible, to minimize chassis ground potential differences. It may also be helpful to insulate each piece of unbalanced equipment from its mounting rails in the rack by means of nylon 10-32 screws and insulating washers between rails and faceplates.

Once the system is properly grounded, proceed with the console power supply installation and connection (next section).

Power Supplies

The A-2000 console is powered by a Wheatstone Model PSC-D340 rackmount power supply. This heavy duty unit occupies three 19” wide rack spaces (total height 5-1/4”). Convection cooled, it requires ample ventilation space above and below it. The PSC-D340 generates a lot of heat in the course of normal operation — do not mount heat sensitive devices in the same rack cabinet.

Note the power supply should be mounted in an equipment rack within fifteen feet of the console (but no closer than 3 feet). Avoid locating any high gain equipment (such as phono preamps, tape recorders, etc.) too near the rackmount supplies, to avoid magnetic interference into that equipment.

A-2000 / Apr 2001

If failsafe redundant supplies have been ordered, you will be installing two units and an additional rackmount panel.

page 1 – 4

I N S T A L L A T I O N a n d P O W E R

Once the supply is rackmounted, it should be connected to the console using the factory supplied cable. The console’s power supply connector is located at the rear of the console, at the right end of the meterbridge bottom pan. If you are using one supply, connect it to the console connector. If you are using two supplies (failsafe option), connect the long power supply cable to the center connector of the rackmount failsafe panel. Then connect one supply with a short cable to either of the two remaining connectors on the failsafe panel and connect the second supply with a short cable to the last connector. Note that the power supply cable’s 10-pin female connector has to be rotated until its locating pins match the male connector on the console. Do not force a connector on; it attaches easily when properly aligned. Connect the cable first to the console, then to the rear of the rackmount power supply.

Note each power supply is fitted with a 3-wire grounded AC cord that should be plugged into a "clean" AC power source, that is, an AC source that feeds only the control room audio gear. This source should be a separate feed from those powering lighting, air-conditioning, or any other non-audio machinery. The third pin ground wire of the AC source should be tied to the central system ground point. Note that while the AC

power cord ground wire terminates at the power supply chassis, it does

NOT connect to the A-2000 console common; the console itself must be grounded separately. (See previous section, "System Ground".)

The power feed recommended in the text is often installed and referred to in studios as an “isolated AC ground” outlet.

It is usually orange in color.

Failsafe Dual Redundant Supply

Wheatstone failsafe power supply systems use two separate rackmount power supplies for each piece of powered equipment. Though either is capable of running a full load on its own, in failsafe operation both units run in tandem: if one fails, the other takes over, assuring uninterrupted operation.

NOTE dual failsafe supplies have their outputs trimmed to entirely different settings than stand-alone single units, and are MEANT to be run in tandem.

In order for failsafe systems to perform as designed, always have

BOTH rackmount supplies powered up and connected to their associated equipment.

Energizing

Assuming the A-2000 console mainframe is properly placed and grounded, and its PSC-D340 power supply correctly rackmounted and connected to the console, you may now energize the PSC-D340 rackmount power supply by plugging it into the AC mains. The five

LEDs on the power supply front panel should light up to indicate the presence of their respective voltages. The console's LED meters will illuminate and individual module switches will assume factory default settings.

Audio and Control Wiring

All audio and control I/O connections to the A-2000 console are made through multipin DB-25 connectors located on the top of each module. The output module also has a DB-9 connector.

The Insulation Displacement Connector System

The I/O wiring interface system is based on insulation displacement technology. A special AMP wiring tool is included with each console; it is auto-indexing, and allows individual wire connections to be positively made with a single squeeze of the tool's trigger. The trigger action is ratchet controlled, and will not release until a full connection is made. Once released, the multipin connector held in the tool's jaw automatically indexes to the next connector pin. The technology is such that no stripping, soldering or tinning

Note the right angle hood with self-locking tabs. The tool, multipin connectors (with gold plated pins) and latching hoods are supplied with each console.

of wire ends is required; all that is needed is for the wires destined for the connector be snub cut and laid out in order (although tubing should be used on bare drain wires). An empty DB-25 (or in the case of the optional LSR-500 rackmount line switcher, a DB-9) connector is inserted into the tool, indexed to the first pin, and the wires are inserted one by one into the jaw and the trigger squeezed. In this way a single multipin connector can be completely wired up in a minute or two.

In the event of a wiring error, connector pins may easily be removed from the shell with the wire still attached, and inserted into the correct position.

Observe the side of the connector, with the metal part down. You will see a row of "Vees"—simply press the top of the vee together with a scribe or other sharp instrument; this will unlock the pin from the shell, and it can be removed and inserted into the correct position. Spread the vee apart to lock the pin in the new position. It should never be necessary to discard a connector due to a wiring error.

Note that mating hoods for each connector are also supplied with the console. These have locking screws that hold the connectors securely to the bottom of the console mainframe.

Connection Procedures

As supplied from the factory, the console requires no logic connections to function. Therefore an orderly installation begins with the audio wiring. Note this manual is organized by module type (inputs, outputs, monitor modules, etc.); each chapter contains detailed wiring instructions for its module type. Proceed through the manual, chapter by chapter, until all modules have been wired to suit your particular installation requirements. Once proper audio operation is verified, go back to each individual chapter and proceed with control wiring.

Analog Insert Points

The MONO MIC INPUTS (MM-2000) have insert patch points in their signal chains to allow outboard audio processing.

Normally these points are internally bridged at the factory (via

PCB-mounted programming dipswitch) prior to shipment. If you intend to use outboard signal loops at these points, you must reprogram this dipswitch. See page 2-3 (mic inputs).

Unbalanced Connections (analog audio)

ANALOG INPUTS — Wire to the console with typical shielded two conductor cable (like Belden 9451), just as if you were connecting a balanced source. At the unbalanced source machine’s output, connect the black wire (LOW) to the shield. If the machine has a -10 dBu output, don’t hesitate to turn module input gain as high as is needed.

ANALOG OUTPUTS — A-2000 consoles use a balanced output circuit which behaves exactly like the secondary of a high-quality transformer, with no center tap—this output is both balanced and floating. Either the HIGH or LOW side of the output should be strapped to ground, with the output taken from the other side. (Normally you’d strap LOW to ground, and take HIGH to feed your unbalanced equipment.)

Modules Layout

The A-2000 console’s mainframe comes supplied with 22 input modules, an output module, a control room/studio module, and a studio two module. Each module type has its assigned slot (see drawing on page 1-9). Also there can be optional modules: a superphone module, a line select module, and a tape remote module. Optional modules can be placed in any input slot.

Wiring Procedure - Double Connection to One Pin

ref: DB-25 male multi-pin connector

Most audio equipment machine interfaces (as well as Wheatstone consoles) use subminiature D-type connectors. Sometimes the interfaces require making two connections to a single DB pin. If the wiring has been set up using punchblocks, this is not a problem; however, for situations where direct machine-to-console wiring is used, Wheatstone recommends the following procedure:

1) Connect the first wire to the desired pin as you normally would.

2) Note connector pins may easily be removed from the DB-25 shell with the wire still attached: Hold the connector with the metal part down and observe its side. You will see a row of "Vees"—simply press the top of the selected vee together with a scribe or other sharp instrument; this will unlock the pin from the shell, allowing it to be removed.

3) With the pin removed, strip out a short section of insulation from the connected wire and wrap and solder the second wire to the first as shown above.

4) A short piece of heatshrink tubing (pictured here before being slid into place) completes the connection.

5) Re-insert the pin into the DB-25 shell, spreading the vee apart to lock it in place.

Mono Mic Input Module

(MM-2000)

Module Overview

MM-2000 modules are for microphone input signals (-50dBu nominal). Each module accepts two mono sources: A and B, switched at the top of the module.

Phantom power is available at both input ports; it may be selectively activated by a dipswitch SW1 pos 2 (the factory default is OFF). Recessed front panel multi-turn trimpots (range 38dB) adjust the level of the A and

B inputs independently.

Example: with a microphone input of –60dBm @150

at the port, gain trim can set levels from -22dBu to +16dBu (note maximum preamp gain is

+76dB).

An analog insert point (+4dBu balanced) is provided: it is post-trim and may be bypassed by a dipswitch SW1 pos1 (the factory default is

BYPASSED).

Output switches assign the selected source signal to any combination of the console’s four outputs: two stereo outputs—PGM (program) and

AUD (audition); and two mono outputs—MONO and MXM (mixminus). Note that the assignment to the MXM output is post-fader, preon, while the other assignments are post-fader, post-on.

Level is set by a long-throw fader.

The channel ON and OFF switches are at the bottom of the module.

In addition to being controlled remotely, these can also be programmed

(via dipswitch) to perform a variety of console control functions, including activating control room and studio mutes, external tallies, and timer restart.

All audio and control input and output signals are made via a multipin DB-25 connector mounted on the top of each individual module and located underneath the hinged meterbridge.

Internal Programming Options

Internal programming for the mono mic module is made via printed circuit board (PCB) mounted dipswitch SW1 located on the top of the module (beneath the DB-25 connector). Note that when a dipswitch position is thrown to the right it is ON.

Insert Bypass

Dipswitch SW1 position 1 will bypass the module’s insert point in and out of the audio signal chain. Note that the factory default is “insert bypassed”. In other words, when shipped from the factory SW1 position

1 is thrown to the right.

Phantom Power

Dipswitch SW1 position 2 turns phantom power on for the module’s two microphone input ports.

Mutes

When a microphone is live in a room, that room’s monitor speakers must be muted to prevent feedback. The A-2000 console has two mute control lines: control room/ HDPN 3 and studio/studio two. Each of these is activated by an A microphone input. The dipswitch SW1 programs these muting functions:

SW1 position 4 mutes the studio/studio two when source A is ON

SW1 position 5 mutes the control room/HDPN 3 when source A is

ON

Timer Restart

The console’s digital timer can be programmed to automatically reset to zero and begin counting up when the module’s ON button is pressed.

SW1 position 6 activates timer restart

Local/Ready

The module’s channel OFF switch normally has its LED indicator controlled by the switch itself (Local). This is the factory default setting.

However, should you wish to have the LED function as a Ready light for an external source machine, dipswitch SW1 position 7, when thrown to the left, passes control to the Ready input on the module’s DB-25 connector.

A closure between the Ready input (DB-25 pin 2) and Digital Ground (DB-

25 pin 19) will activate the OFF switch LED. As long as the closure is maintained, the LED will be lit.

Note the factory default setting for phantom power is OFF.

page 2 – 3

Talkback

Typically, one of the A-2000 console’s input modules will be used for the control room (CRS) console operator’s microphone. The third position of the dipswitch SW1 allows that microphone to also function as a talkback mic. It places the signal (pre-fader, pre-on/off) onto the console’s talkback bus. When the console operator presses a TB switch on the console’s CRS-

2000 Control Room/Studio module, the talkback bus (which is carrying his microphone signal) will interrupt the regular monitor signal being fed to the studio and talent will hear his voice through the studio monitor speakers.

In order for the studio to reply to the console operator, the MM-2000 module controlling the studio’s microphone signal must be routed to the console’s cue bus, where it can interrupt the regular control room monitor feed and be heard by the operator. This is accomplished by a user-supplied

TB switch in the studio. The switch provides a momentary closure between the module’s DB-25 connector “TB to CR ” control pin and

Digital Ground (see page 2-6 for wiring details). As long as this closure is maintained (i.e., as long as talent holds down the studio TB button) the module’s (pre-fader, pre-on/off) signal will be placed on the console’s Cue bus.

Hook-Ups

As stated before, all user wiring to and from MM-2000 modules takes place at the DB-25 multi-pin connector mounted on the top of each module. A pinout drawing on page 2-7 shows all wiring connections at a glance.

Audio Connections

These include A and B mic inputs, and insert in and out. The mic input level is nominally -50dBu. Insert points are +4dBu balanced in and out. All signals are analog mono.

Note the insert points are normally bypassed by PCB-mounted dipswitch SW1 pos 1 (see page 2-3). The Insert Out pins may be used as a channel direct output if desired.

To Turn the Module ON & OFF from a Remote Location

REMOTE ON — Activates the module’s channel ON switch.

Provide a momentary closure between Pin 14 (Remote On) and Digital

Ground (Pin 19). This will latch the module ON. (User-supplied momentary contact switch required.)

REMOTE OFF — Activates the module’s channel OFF switch.

Provide a momentary closure between Pin 16 (Remote Off) and Digital

Ground (Pin 19). This will latch the module OFF. (User-supplied momentary contact switch required.)

COUGH — Temporarily Mutes the module. Provide a closure between Pin 1 (Cough) and Digital Ground (Pin 19). This will turn the module OFF. Note this is a non-latching mode; the module will turn

ON again as soon as the closure stops. (User-supplied momentary contact switch required.)

To START and STOP Remote Source Machines Using Module

ON/OFF Switches

EXTERNAL START — Hook up the remote machine’s “start” control pins to the MM-2000 module’s DB-25 connector control pins: for START wire to pins 3 and 5.

EXTERNAL STOP — Hook up the remote machine’s “stop” control pins to the MM-2000 module’s DB-25 connector control pins: for STOP wire to pins 4 and 5.

To Control the Module’s OFF Switch LED with an External

Source Machine

READY — Hook up the remote machine’s Ready output to the

MM-2600 module’s DB-25 connector pin 2 (Ready) and pin 19

(Digital Ground). The module’s Ready port is looking for a contact closure. As long as the closure is maintained the OFF switch LED will be illuminated.

Talkback to Control Room

If an MM-2000 module is being used for a studio microphone, this connection allows talkback from that studio to the console operator.

Provide a closure between Pin 17 (TB to CR) and Digital Ground (Pin

19). This will cause the module’s pre fader signal to be sent to the console’s Cue bus, where it may be heard by the console operator. This non-latching condition continues until the closure is released. (Requires user-supplied momentary action TALKBACK switch at the studio microphone location.)

On Tally

Lets the module’s channel ON switch control an on-air light or other

“microphone on” indicator at a remote location. This control function provides a continuous +5 volt signal at Pin 15 (On Tally) whenever the module is ON.

This signal can be used to control an externally powered tally light that requires a continuous signal to function. Or an external tally light

(i.e., LED) can be powered from the input module by connecting the external LED to Digital Ground (Pin 19) and the On Tally port. In either case, current should not exceed 30 milliamps.

Tally B

Provides a remote indication that the module’s B source has been selected. This control function provides a continuous closure (open collector) between Pin 6 (Tally B) and Digital Ground (Pin 19) whenever the B source is selected.

This closure can be used to control an externally powered tally light that requires a continuous closure to function. An external tally light

(i.e., LED) can be powered from the input module by connecting the external LED to +5V Digital (Pin 18) and the B Tally port. Current should not exceed 30 milliamps.

Stereo Line Input (SL-2000)

Module Overview

SL-2000 modules are for stereo line input signals.

Each module accepts two stereo sources: A and B, switched at the top of the module. Recessed front panel multi-turn trimpots adjust the left and right levels. Output switches assign the selected source signal to any combination of the console’s four outputs: two stereo outputs—PGM

(program) and AUD (audition); and two mono outputs—MONO and

MXM (mix-minus). Note that the assignment to the MXM output is postfader, pre-on, while the other assignments are post-fader, post-on.

A CUE switch places the module’s signal on the console’s cue bus, where it may be heard on the meterbridge mounted cue speaker and/or as an interrupt to the console operator’s headphones and/or control room monitor speakers. The various cue interrupt modes are programmed at the console’s CRS-2000 (Control Room/Studio ) module via PCB-mounted dipswitch. See page 5-3.

Level is set by a long-throw fader.

Channel ON (START) and OFF (STOP) switches are at the bottom of the module. In addition to being controlled remotely, these can also be programmed (via internal PCB-mounted dipswitch) to perform a variety of functions, including starting and stopping external source machines, activating control room and studio mutes, external tallies, and timer restart. The STOP switch’s LED can be controlled by an external source machine to act as a “ready” indicator.

All audio and control input and output signals are made via the multipin DB-25 connector mounted on the top of the module and located underneath the hinged meterbridge.

Internal Programming Options

All internal programming is made via PCB mounted dipswitch SW1 located on the top of the module (beneath the DB-25 connector). Note that when a dipswitch position is thrown to the right it is ON.

Mutes

Like MM-2000 inputs, an SL-2000 module can be programmed to mute speakers when the channel is ON. The A-2000 console has two mute control lines: control room/HDPN 3 and studio/studio two. Each of these is activated by an A input source.

SW1 position 4 mutes the studio/studio two when source A is ON

SW1 position 5 mutes the control room/HDPN 3 when source A is ON

Timer Restart

The console’s digital timer can be programmed to automatically reset to zero and begin counting up when the module’s ON button is pressed.

SW1 position 6 activates timer restart

Local/Ready

The module’s channel OFF switch normally has its LED indicator controlled by the switch itself (Local). This is the factory default setting.

However, should you wish to have the LED function as a Ready light for an external source machine, dipswitch SW1 position 7, when thrown to the left, passes control to the Ready input on the module’s DB-25 connector. A closure between the Ready input (DB-25 pin 2) and Digital Ground (DB-25 pin 19) will activate the OFF switch LED. As long as the closure is maintained, the LED will be lit.

Talkback

Typically, one of the A-2000 console’s input modules will be used for the control room (CRS) console operator’s microphone. The third position of the dipswitch SW1 allows that microphone to also function as a talkback mic.

It places the signal (pre-fader, pre-on/off) onto the console’s talkback bus.

When the console operator presses a TB switch on the console’s CRS-2000

Control Room/Studio module, the talkback bus (which is carrying his microphone signal) will interrupt the regular monitor signal being fed to the studio and talent will hear his voice through the studio monitor speakers.

In order for the studio to reply to the console operator, the SL-2000 module controlling the studio’s microphone signal must be routed to the console’s cue bus, where it can interrupt the regular control room monitor feed and be heard by the operator. This is accomplished by a user-supplied

TB switch in the studio. The switch provides a momentary closure between the module’s DB-25 connector “TB to CR” control pin and Digital Ground

(see page 3-5 for wiring details). As long as this closure is maintained (i.e., as long as talent holds down the studio TB button) the module’s (pre-fader, pre-on/off) signal will be placed on the console’s Cue bus.

To Turn the Module ON & OFF from a Remote Location

In the case of stereo line input modules, “remote location” can also refer to a remote source machine that is feeding its audio to the module in question. A contact closure (which may be sourced by the external machine), will activate the module’s channel ON and OFF switches.

REMOTE ON — Activates the module’s channel ON switch. Momentary connect Pin 14 (Remote On) and Digital Ground (Pin19) to latch the module ON.

REMOTE OFF — Activates the module’s channel OFF switch.

Momentary connect Pin 16 (Remote Off) and Digital Ground (Pin 19) to latch the module OFF.

COUGH — Temporarily Mutes the module. Provide a closure between Pin 1 (Cough) and Digital Ground (Pin 19). This will turn the module OFF. Note this is a non-latching mode; the module will turn ON again as soon as the closure stops. (User-supplied momentary contact switch required.)

To START and STOP Remote Source Machines Using Module ON/

OFF Switches

EXTERNAL START — Hook up the remote machine’s “start” control pins to the SL-2000 module’s DB-25 connector control pins: for START wire to Pins 3 and 5.

EXTERNAL STOP — Hook up the remote machine’s “stop” control pins to the SL-2000 module’s lower DB-25 connector control pins: for

STOP wire to Pins 4 and 5.

To Control the Module’s OFF Switch LED with an External Source

Machine

READY — Hook up the remote machine’s Ready output to the

SL-2000 module’s DB-25 connector pin 2 (Ready) and pin 19 (Digital

Ground). The module’s Ready port is looking for a contact closure. As long as the closure is maintained, the module’s OFF LED will be illuminated.

Talkback to Control Room

If an SL-2000 module is being used for a studio microphone, this connection allows talkback from that studio to the console operator.

Provide a closure between Pin 17 (TB to CR) and Digital Ground (Pin 19).

This will cause the module’s pre fader signal to be sent to the console’s Cue bus, where it may be heard by the console operator. This non-latching condition continues until the closure is released. (Requires user-supplied momentary action TALKBACK switch at the studio microphone location.)

On Tally

Lets the module’s channel ON switch control an on-air light or other

“microphone on” indicator at a remote location. This control function provides a continuous +5 volt signal at Pin 15 (On Tally) whenever the module is ON.

This signal can be used to control an externally powered tally light that requires a continuous signal to function. Or an external tally light

(i.e., LED) can be powered from the input module by connecting the external LED to Digital Ground (Pin 19) and the On Tally port. In either case, current should not exceed 30 milliamps.

Tally B

Provides a remote indication that the module’s B source has been selected. This control function provides a continuous closure (open collector) between Pin 6 (Tally B) and Digital Ground (Pins 19) whenever the B source is selected.

This closure can be used to control an externally powered tally light that requires a continuous closure to function. An external tally light

(i.e., LED) can be powered from the input module by connecting the external LED to +5V Digital (Pin 18) and the B Tally port. Current should not exceed 30 milliamps.

Output Module

(OM-2000)

Module Overview

The master output module handles the console’s Program, Audition, and Mono/Mix-Minus outputs. All outputs are calibrated with recessed front panel multi-turn trimpots.

Each A-2000 console has two pairs of left-right VU meters: PGM and SWT (switched) located on the console’s meterbridge. The switched meter follows the SELECT switching, allowing the console operator to meter PGM, AUD, MONO and MXM, and an external stereo line signal (analog, +4dBu balanced), which may be brought into the module on its DB-25 connector.

The OM-2000 module houses the master Cue LED. Whenever Cue is activated anywhere on the console this LED will illuminate and the

CUE signal will automatically appear on the switched VU meter pair.

When cue is de-activated, the switched meter pair goes back to its previously selected signal.

The CUE master level control sets the level of the console’s cue signal.

Whenever CUE is activated elsewhere on the console (stereo line inputs, the superphone module, or for studio talkback) its signal will appear at the console’s built-in cue speaker mounted in the meterbridge. Depending on how the CRS-2000 module has been programmed, cue can also interrupt the control room monitor speakers. The way Cue interrupts the control room/studio outputs is determined by PCB-mounted dipswitch. See “Cue

Interrupt” on page 5-3.

The OM-2000 module also generates the console’s monitor signals, which feed the Control Room and Studio modules.

At the bottom of module are the timer control buttons (the timer display is mounted in the righthand end of the console meterbridge):

AUTO – enables timer restart functions from programmed input modules’

ON buttons.

S/S - START/STOP - halts the timer, holds the last count, and then restarts and accumulates the count when depressed again.

RESET - return to zero (if the timer is stopped it will hold at zero; if it is running it will reset to zero and immediately begin counting up).

HOLD – when held down freezes the timer display (the counter keeps on going); when released the display catches up to the current count.

All user wiring to and from the OM-2000 module takes place at

DB-25 and DB-9 multi-pin connectors mounted on top of the module and located underneath the hinged meterbridge. All analog audio is

+4dBu balanced. Pinout drawings on pages 4-5 show all wiring connections at a glance.

Control Room/Studio

Module

(CRS-2000)

Module Overview

The CRS-2000 module is the A-2000 console operator’s monitor module. It allows the operator to listen to the console’s two stereo (PGM

& AUD) outputs, two mono (MXM & MONO) outputs and two external stereo line level inputs brought directly into the module.

A recessed front panel multi-turn trimpot adjusts talkback level.

The CRS-2000 module also houses three console monitor circuits, which follow the source selection switches. They are:

CONTROL ROOM (CR)—a dedicated output designed to drive a separate, user provided power amp/speaker system in the main control room;

STUDIO—a second stereo output intended for a remote (i.e., non CR) studio power amp/speaker system;

HEADPHONE (HDPN)—an additional output (w/built-in power amp) that drives the console operator’s headphones. There are two types of headphone output: the +4dBu balanced output at the module’s right DB-

25 connector (B), and the headphone jack mounted in the right-hand corner of the console, which is actually the output from a built-in headphone amplifier.

MONITOR OUTPUT—a monitor source select (without CUE or

MUTE interrupt) independent output.

The CRS-2000 module has a talkback switch. When the talkback switch is pressed (it is momentary action), any microphone assigned to talkback bus (see pages 2-4 and 3-3) will interrupt the regular monitor signals being sent to the studio.

All user wiring to and from the CRS-2000 module takes place at the

DB-25 multi-pin connectors mounted at the top of the module and located underneath the hinged meterbridge. There are two connectors: the left one accepts the external 2 source input and handles audio outputs; the right accepts the external 1 source input and handles audio outputs. All audio connections are stereo line level analog signals (+4dBu balanced). A pinout drawing on page 5-6 shows all wiring connections at a glance.

Internal Programming Options

Internal programming for the control room/studio module is made via printed circuit board (PCB) mounted dipswitch SW1 located on the top of the module (beneath the DB-25 connectors). Note when a dipswitch position is thrown to the right it is ON.

Cue Interrupt

Dipswitch SW1 pos. 5-7 determines how the console’s Cue function will interrupt regular monitor signals:

SW1 position 7 sends cue to CR left

SW1 position 6 sends cue to CR right

SW1 position 5 sends cue to HDPN*

CR/Cue Mute

The audio from both the control room speakers and the console’s builtin meterbridge speaker can easily be picked up by the console operator’s microphone. This is a potential source of feedback. For this reason the console provides muting to the control room output and the built-in cue speaker whenever a mic programmed for control room/HDPN3 mute is turned ON with A selected as the input source (see pages 2-3 and 3-3).

SW1 position 4 will mute cue and the CR output whenever an input channel set to activate the CR mute is ON

Studio Mute

When SW1 pos 3 is activated, it automatically mutes talkback out and the console’s studio output whenever an input module programmed for studio/studio 2 mute is turned ON with A selected as the input source. This is used to prevent feedback from studio mics.

Studio Dim

Input modules controlling studio microphones can be programmed to

MUTE a studio whenever the module is turned on (i.e., it’s microphone is live). If you wish, you can have a studio DIM (drop -20dB in level) instead of MUTE:

SW1 positions 1 causes Studio right to DIM

SW1 positions 2 causes Studio left to DIM

Note the DIM functions also affect the talkback interrupt. Note also if the studio is muted, talkback cannot be heard. However, if the studio is programmed to DIM instead of MUTE, talkback audio could presumably make it from the studio monitor speakers to the open studio mic.

Studio Two Module

(SS-2000)

Module Overview

The SS-2000 module is similar to the CRS-2000 module. The monitor signal being sent to this studio follows the source select switching. This switching is indentical to the control room/monitor module’s and includes the console’s two stereo (PGM & AUD) outputs, two mono (MXM &

MONO) outputs and two external stereo line level inputs brought directly into the module.

A recessed front panel multi-turn trimpot adjusts talkback level.

The SS-2000 module also houses three console monitor circuits, which follow the source selection switches. They are:

STUDIO—a stereo output intended for a remote studio power amp/ speaker system;

HEADPHONES (HDPN2 & HDPN3)—an additional line level balanced outputs to drive power amplifiers for guest or produce headphones.

Both pre and post fader outputs are provided.

MONITOR OUTPUT—a monitor source select (without CUE or

MUTE interrupt) independent output.

The SS-2000 module has a talkback switch. When the talkback switch is pressed (it is momentary action), any microphone assigned to talkback bus (see pages 2-4 and 3-3) will interrupt the regular monitor signals being sent to the second studio output.

All user wiring to and from the SS-2000 module takes place at the DB-

25 multi-pin connectors mounted at the top of the module and located underneath the hinged meterbridge. There are two connectors: the left one accepts the external 2 source input and handles audio outputs; the right accepts the external 1 source input and handles audio outputs. All audio connections are stereo line level analog signals (+4dBu balanced). A pinout drawing on page 6-6 shows all wiring connections at a glance.

Superphone Input

(SPN-2000)

Module Overview

The SPN-2000 input module is used for telephone call-ins, and can handle two callers. Caller signals enter the module from your station hybrid; each caller has its own long-throw fader that controls the level of the caller’s voice.

Output switches assign callers to any combination of the console’s four outputs: PGM (program), AUD (audition), MONO and MXM (mixminus).

Two recessed front panel trimpots at the top of the module adjust the console’s CALLER levels.

The channel ON (red) and OFF (amber) switches are at the bottom of the module. These can be programmed (via PCB-mounted dipswitch) to activate control room and studio mutes, and timer restart.

All audio and control signals hook-ups are made via a multi-pin DB-

25 connector mounted on the top of the module and located underneath the hinged meterbridge.

Caller Set-Ups

Pre-air segment communication between the console operator (DJ) and callers is via CUE button which places the callers’ voices on the console’s cue speaker (or control room speakers/operator’s headphone if the CRS-2000 module’s cue interrupt function has been so programmed).

A typical call-in segment might proceed as follows:

Caller phones in, DJ picks up off-air during a track play to set up the call. He assigns his mic channel and the phone module to MXM, places the caller in CUE, and talks to the caller. Neither the DJ mic nor the phone module need to be ON for two-way communication.

When he is ready to take the call on-air, the DJ makes sure both modules (his mic and phone) are assigned to PGM and turns them ON. He then deactivates caller CUE to hear the normal feed.

Internal Programming Options

Internal programming is accomplished via printed circuit board (PCB) mounted dipswitch SW1, located on the top of the module (beneath the

DB-25 connector). Note when a dipswitch position is thrown to the right it is ON. The SPN-2000 PCB card contains PCB-mounted trimpots which may be used to set the module’s output feed levels.

Mutes

When the SPN-2000 phone channel ON switch is pressed, it can activate console mute functions. Dipswitch SW1 determines which of the console’s two mute lines will be activated:

SW1 pos 5 mutes the control room when the phone module is ON*

SW1 pos 4 mutes studio when the phone module is ON

Timer Restart

When the module is turned ON, the console’s digital timer can be programmed to automatically reset to zero and begin counting up.

SW1 pos 6 activates timer restart when the phone module’s ON/

START switch is pressed

Gain Trimpots

There are two PCB-mounted trimpots. They are used as follows:

CR1 - sets Callers 1 In port input gain

CR2 - sets Callers 2 In port input gain

Hook-Ups

As stated before, all user wiring to and from SPN-2000 modules takes place at a multi-pin DB-25 connector mounted on the top of the module.

Audio Connections

These include callers 1 & 2 inputs and outputs. All are +4dBu balanced analog mono.

Pin 15 – ON Tally

Pin 16 - Remote Off

Pin 18 - +5V Digital

Pin 19 - Digital Ground

To Turn the Module ON & OFF from a Remote Location

REMOTE ON — Activates the module’s channel ON switch. Provide a momentary closure between Pin 14 (Remote On) and Digital Ground (Pin 19).

This will latch the module ON. (User-supplied momentary contact switch required.)

REMOTE OFF — Activates the module’s channel OFF switch. Provide a momentary closure between Pin 16 (Remote Off) and Digital Ground (Pin

19). This will latch the module OFF. (User-supplied momentary contact switch required.)

To START and STOP Remote Source Machines Using Module ON/

OFF Switches

EXTERNAL START — Hook up the remote machine’s Start control pins to the SPN-2000 module’s DB-25 connector control pins: for START wire to pins 3 and 5.

EXTERNAL STOP — Hook up the remote machine’s Stop control pins to the SPN-2000 module’s DB-25 connector control pins: for STOP wire to pins 4 and 5.

When the module’s ON/START switch is pressed, a closure takes place between START/STOP COMMON and START; when the module’s OFF switch is pressed, a closure takes place between START/STOP COMMON and STOP. These may be used to control a remote tape machine for recording phone segments.

On Tally

Lets the module’s channel ON switch control an on-air light or other

“microphone on” indicator at a remote location. This control function provides a continuous +5 volt signal at Pin 15 (On Tally) whenever the module is ON.

This signal can be used to control an externally powered tally light that requires a continuous signal to function. Or an external tally light (i.e., LED) can be powered from the input module by connecting the external LED to

Digital Ground (Pin 19) and the On Tally port. In either case, current should not exceed 30 milliamps.

Meterbridge

Overview

The console’s meterbridge houses two pairs of left-right VU meters

(Program and Switched; see “Output Module” Chapter 4), the digital timer display, the cue speaker, and the console clock.

The meterbridge assembly hinges open for easy access (VU meter lamp replacement, setting the clock). Simply swing the bridge up and back until it rests in a fully opened position.

Digital Timer

The console timer control buttons are located on the OM-2000 Output

Module (see page 4-2).

The timer is provided with an AUTO-RESTART function so programmed input modules can automatically reset the timer display to zero and start a new count, allowing the announcer to easily track his own pace.

The START/STOP button halts the timer, holds the last count, and then restarts and accumulates the count when depressed again

— perfect for compiling tapes of desired duration.

RESET has a dual-mode capability:

- if you depress it while the timer is counting, the display will instantly reset to zero and start a fresh count;

- if the timer is already stopped, depressing this button will reset the timer to zero, where it will hold until start is pressed, or until an auto restart is activated.

HOLD button allows you to hold the display for a longer viewing duration, while still allowing the counter to continue in the background. Releasing the button will then display the current count.

Console Clock

The Wheatstone digital clock is a six-digit time-of-day clock with LED display. The clock is designed with CMOS circuits and an on-board crystalcontrolled time base oscillator. There are two basic parts to the clock: a main

PCB containing the clock circuits and clock set controls (also may include capacitor backup) and a second PCB containing displays. Clock set controls may be accessed by opening the meterbridge cover.

page 10 – 2

M E T E R B R I D G E

Controls

The clock is controlled by a trimmer and two switches; the trimmer and switches are mounted on the main clock PCB assembly.

The trimmer alters the frequency of the quartz-controlled oscillator, which in turn causes the clock to run slightly slower or faster. In order to keep accurate time, the oscillator must run at 4.096 MHz. The oscillator is set to this frequency at the factory. However, due to the nature of quartz/crystalcontrolled oscillators, there may be a slight change in the frequency of the oscillator during the first few months of operation due to the aging effect of quartz crystals. A minor readjustment of the trimmer will compensate for this effect.

A buffered output of the oscillator is available at TP1 to assist in adjusting the oscillator.

Setting the Time

The setting controls consist of two switches: MODE and SET. To set the clock, open the meterbridge cover:

1) The control switches (mounted on the main clock PCB assembly) are labelled "M" and "S". "M" (Mode) is used to scroll from seconds to minutes to hours; "S" is used to Set the time. The procedure is to set the clock slightly ahead of the current time, hold the second count at "00" until the current time catches up, and then release the count.

2) Press the MODE button until the hour digits blink. Depress the SET button until the desired hour is displayed.

3) Press the MODE button until the minute digits blink. Depress the SET button until the desired minute count is displayed.

4) Press the MODE button until the second digits blink. Depress and hold the SET button; the seconds display will hold at "00". When the current time catches up to the display, release the SET button. The clock will start counting. Hit the MODE button three more times to place the clock into working mode.

Capacitor Backup

With the meterbridge open note the super capacitor at C25. This super capacitor is self charging. Note that the super capacitor does NOT light up the clock display; it powers the clock crystal to keep it from losing count ( it will do this for about one hour).

Operational Modes

The standard factory default clock configuration is crystal-controlled, 12 hour mode, stand-alone operation. However, the clock will operate either from the internal crystal controlled time base or from an ESE master (TC-76,

TC-89, TC-90, autodetect) signal. Because crystal time bases are subject to drift over time, Wheatstone recommends operating the clock in the ESE slave mode for those applications where the exact time is critical.

It can also be programmed to count in either 12 hour or 24 hour modes.

Connect an ESE master at connector CT3 (Pin 1 - Signal, Pin 2 - Shield).

Switch #4 on SW3 sets 12/24 hour mode (Off - 12 hour, On - 24 hour).
