4 Equipment Description

Tape / Aux Outputs

With one Telco module installed, the left chan-

nel output is just the caller. The right channel out-

put is the caller mix-minus audio (TEL1_MM),

which is the output of the assigned bus with the

highest priority.

With two Telco modules installed, the Tape Feed

switch (DS1, switch 3) becomes active. This switch

sets how the caller audio from the other Telco

module gets mixed into the Tape and Aux outputs

on that module.

When the Tape Feed switch is set to the left,

both callers are mixed together onto the left chan-

nel. When it is set to the right, the other caller gets

mixed with the mix-minus audio (TEL1_MM) on

the right channel.

Monitoring Caller 2

Caller 2 can be monitored through the Cue bus

or through the Telco 1 Mix. To monitor Caller 2

separately from Caller 1 in the Studio requires that

an audio jumper be connected from the Aux out-

put of the second Telco module to an External

Input on the Monitor module.

Autofeed

When the Autofeed function is active, the mod-

ule status (On or Off) affects the mix-minus switch-

ing. When the module is On, the Program mix-

minus output with the highest priority is automati-

cally sent to the caller. When the module is turned

Off, the Off-line bus audio is automatically

switched to the caller.

In Manual Mode (Autofeed is not active), the

selected source with the highest priority (Off-line,

Pgm-1, Pgm-2 or Pgm-3) is sent to the caller re-

gardless of whether the module is On or Off.

Note:

  If Off-Line is the only bus selected in

Manual Mode, the caller will not go on-air when

the Telco module is turned On since there is no

Program bus assignment.

A front panel DIP switch sets cue, timer and

record output options. When the Cue Reset switch

is set to the right, the Cue function is turned off

when the Telco module is turned On or Off. When

the Timer Reset switch is set to the right, Telco

module On resets the Timer.

The Tape Feed switch is only active when two

Telco modules are installed. When set to the left,

the CALLER_IN audio (from the other Telco mod-

ule) is mixed with the module’s caller audio on

the left To Tape output. When set to the right, the

audio from the other Telco module is mixed with

the mix-minus audio (TEL1_MM) on the right To

Tape output.

Polyswitch resettable fuses, F1, F2, F3 and F4,

are used on the +12, +16, -16 and +5 VDC con-

nections to protect against short circuit damage.

TP4 (-16 volts), TP5 (+5 volts) and TP8 (+16

volts) allow the voltages to be checked after the

fuses.

MOTHERBOARD

Two motherboard sections are used in the Air-

Wave-12, while three are used in the AirWave-20.

Each motherboard fastens to the bottom of the

mainframe and plugs together using a Mother-

board Interconnect jumper (95-974).  The power

supply cable is hard-wired to the right-hand

motherboard section (schematic 92-1009).

DSP BOARDS

Two DSP (Digital Signal Processing) boards are

used in the AirWave-12, while three are used in

the AirWave-20. Each board plugs into the mother-

board at a right angle from the modules and are

fastened to the mainframe’s inside rear frame.

There are no adjustments or controls on the DSP

boards. Refer to the Motherboard schematics (92-

1007, 92-1008 and 92-1009) in the following dis-

cussion. Because of the proprietary nature of the

DSP boards, a schematic is not included.
