III. Front Panel Control Functions
1. The INPUT SELECTOR control selects the source which will be presented to the outputs
and balanced outputs.
2. The RECORD SELECTOR control selects the source which will be presented to the record
output. Because of the independent controls, one source may be monitored while a
second, different source is being recorded.
3. 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.
4. 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 02b.
However, some sources may produce high output voltages on turn on, which may cause
damage to an amplifier or speakers .
