RECORDING AND PA CONSOLES

1. GENERAL CONFIGURA-

TION. The audio mixer shall

have a mainframe capable

of accommodating

16/24/32 inline input/

output channels, with an

optional meter bridge

consisting of 16/24/32

precision LED bargraph

meters to monitor signal

levels in all inline input

channels and VU meters to

monitor control room

source selection, and an

optional separate expander

console capable of accom-

modating an additional 24

inline input/output chan-

nels that shall connect to

the mainframe via 37-pin D-

sub connectors. Note: The

separate expander frame is

not available for the 16•8

mixer. The mainframe shall

also include an overall

master control section, and

provision for directly

mounting 12V gooseneck

type panel lighting via BNC

connectors.

2. POWER SUPPLIES. All

necessary operating volt-

ages for the mainframe

shall be supplied by a two-

rack- space external power

unit that shall connect to

the mainfram via a 7-

conductor cable terminated

in an appropriate connector,

and all necessary operating

voltages for the expander

console shall be supplied by

a two rack space external

power unit that shall con-

nect to the expander frame

via a 7-conductor cable

terminated in an appropriate

connector.

3. CHANNEL INPUTS/

OUTPUT TERMINATIONS.

Each inline input/output

channel shall have the

following inputs and outputs:

a) one balanced

transformerless input for low-

impedance microphone via

3-pin female XLR connector

with gold-plated pins, b) one

balanced/unbalanced

transformerless input for line-

level signals via 3-conductor

/4" connector, c) one

balanced/unbalanced

transformerless input for

signals from tape, which shall

be switchable globally for 8

channels for a nominal

–10dBV or +4dBU operating

level, d) one unbalanced

line-level direct output via

2-conductor

/4" connector,

e) one unbalanced output/

input channel patching insert

via 3-conductor

/4" connec-

tor (tip = send, ring =return).

4. INPUT SWITCHING. Each

inline input/output channel

shall have: a) a mic/line

switch to select signals from

either the mic input or the

line input, b) a flip switch to

determine whether the

mic/line input is fed to the

channel’s primary signal path

while the tape input feeds

the Mix-B (Monitor) signal

path, or whether the tape

input feeds the channel’s

primary signal path while the

mic/line input feeds the Mix-B

(Monitor) signal path.

5. INPUT LEVEL ADJUSTMENT.

Each inline input/output

channel shall be equipped

with a channel trim control to

adjust the gain of the input

amplifier stage to appropri-

ately match levels presented

to the mic and line inputs.
