Architectural Specifications

The mixer shall be a solid-state unit capable of
combining six microphone and two line level inputs, or
five microphone. two line level and one pair of phono
inputs and shall be capable of delivering +18 dBm with
less than 0.2% THD. It shall have a frequency response
of 20 Hz - 20 kHz, i1 dB (unbalanced input). 35 Hz ~ 20 kHz,
+1 dB. -2 dB (balanced input). at +18 dBm or less.

Each of the six microphone inputs shall accommodate
an unbalanced high impedance microphone or a
balanced low impedance microphone. The microphone
input circuits shall be equipped with 9-pin sockets for
mounting optional plug~in transformers to permit the use
of low impedance microphones. Three-pin female
XL-type sockets with positive latch locking devices shall
be provided for the microphone channels. Each
microphone input shall be equipped with an input pad
switch on the front panel. selectable from O. 15. or
30 dB attenuation

The two line level inputs shall accommodate an
unbalanced high impedance input. or a balanced high
or low impedance input. The line level inputs shall be
equipped with 9-pin sockets for mounting optional
plug-in transformers. A five screw terminal board shall
be provided for connecting each line input.

One microphone input shall alternatively
accommodate a magnetic phonograph cartridge input.
A dual RCA-type phono jack shall be provided to allow
program input from a stereo source.

The mixer shall have individual low and high
frequency tone controls. The low frequency control shall
affect output below 500 Hz (:3 dB reference point)
and the high frequency control shall affect the output
above 2.5 kHz (:3 dB reference point).

A 6.3 mm (A inch) phone jack shall be provided on
the face panel to allow headset monitoring or
connection to an auxiliary amplifier, The monitor output
shall be affected by both the master level control and
the tone controls and shall be provided with a separate
gain control. A CUE lN/OUT switch shall be provided
to allow the mixer output to be switched off.

For a balanced 600 0 output, an optional accessory
output transformer shall be available.

The mixer shall occupy three standard ElA rack
spaces and shall operate on 120/240 V AC. 50/60 Hz.

The mixer shall be the JBL Model 5302.
