The Front Panel Controls
and How to Use Them
INPUT SELECTOR:
The INPUT selector switch is located at the upper
left on the front panel. This switch selects the input
desired for normal listening. The input program
selected will also appear at the TAPE OUTPUT jacks.
MODE SELECTOR:
The MODE SELECTOR allows you to identify each
stereo channel, create monophonic program
material, and direct program material to one channel
or the other. This switch controls the main outputs
only, and not the tape outputs.
The switch controls the program in seven ways.
L TO L&R: Connects the left input to both left and
right output circuits.
R TO L&R: Connects the right input to both left and
right output circuits.
STEREO REV: Connects the left input to the right
output circuit and the right input to the left output
circuit.
STEREO: Connects the left input to the left output
circuit and the right input to the right output circuit.
Use this STEREO position for normal listening.
MONO (L+R): Adds the left and right inputs
together to produce a monophonic program and con-
nects to both output circuits.
L + R TO L: Connects the left plus right program to
the left output circuit only.
L + R TO R: Connects the left plus right program to
the right output circuit only.
EQUALIZER FREQUENCY CONTROLS:
Each of five EQUALIZER FREQUENCY controls
raises or lowers the amplitude of a band of frequen-
cies centered on the frequency marked above the
control. Both left and right channels are affected.
The center, or flat position of the control has a de-
tent for easy reference. At detent, the equalizer band
is removed from the preamp circuit.
Use the EQUALIZER FREQUENCY controls to
modify the sound and balance of program material.
Here are some suggestions from which to start.

HEADPHONE VOLUME:
This control allows independent adjustment of
the headphone volume (as well as LINE OUTPUT)
without affecting the main listen volume. The main
volume control does affect headphone volume and
must be turned up to a reasonable level prior to ad-
justing the headphone volume control.
VOLUME CONTROL:
The VOLUME control is a precision step control
