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

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

e) one unbalanced output/
input channel patching insert

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.
