III. Front Panel Control Functions
1. The INPUT SELECTOR control selects the source which will be presented to the
unbalanced OUTPUTS and BALANCED OUTPUTS.
2. The RECORD SELECTOR control selects the source which will be presented to both of
the record outputs. Because of the independent controls, one source may be monitored
while a second, different source is being recorded.
Caution: Do not attempt to activate the record mode of a recording device when it is
selected as a recording source. This is an illogical state and may cause oscillation of the
recording device. If the monitor control is set for this device, the oscillation may produce
damaging levels at the unbalanced outputs and balanced outputs.
3. The MODE control allows selection of stereo and reversed stereo, as well as mono
(summed) output.
4. The BALANCE control works by attenuating the right channel when being rotated from
the detent in the counterclockwise direction, and conversely, the left channel for
clockwise rotation.
The element is conductive plastic. Adjustment is continuously adjustable allowing for
infinitesimal adjustments to match channel gain, which is impossible with stepped
controls.
5. The OUTPUT LEVEL control is a precision tracking, audio taper, conductive plastic
potentiometer used to adjust the voltage level at the outputs and balanced outputs.
Clockwise rotation, of course, increases output.
Select a source with the INPUT SELECTOR switch and advance the OUTPUT LEVEL control
to the level you wish. Keep in mind that your input sources will vary in level which can,
when switching from one input to another, abruptly yield uncomfortable sound pressure.
Note: If a power interruption occurs to the system, reduce the OUTPUT LEVEL control gain.
The resumption of power will cause no noise pulses in the FET PREAMPLIFIER 01. However,
some sources may produce high output voltages on turn on, which may cause damage
to an amplifier or speakers .
