DETAILED INSTALLATION

1. The first four buttons select the input source.
2. The PROCESSOR button switches in an audio processor (surround sound, equalizer, etc.)
3. The MONO button combines the left and right audio channels.
4. The BYPASS button will cause the gain to drop to unity, bypassing the normal 12dB
standard gain of the 07x.
5. Volume and balance setting is indicated by the decibel (dB) display.
FOR VOLUME ADJUSTMENT: The volume display shows "relative" volume level. When the
display reads "99" there is no decibel attenuation, "00" is the maximum decibel attenuation,
and level changes occur in 1dB increments.
FOR BALANCE ADJUSTMENT: In the window next to the number display are three indicator
LEDs, MAIN, LEFT, and RIGHT. In the MAIN mode (blue LED) the display readout shows
volume level. In the LEFT mode (white LED) the display readout shows left balance level. In
the RIGHT mode (red LED) the display readout shows right balance level. In addition the
display will flash on and o when the volume is muted.
When adjusting individual channel level for balancing purposes, the display shows "actual"
decibel level. In other words, the default value of "0" on the LEFT or RIGHT channel mode,
shows that the channel is not attenuated. A value of "99" shows the channel is -99 db below
full volume.
6. The VOLUME/BALANCE is controlled by the optical encoder control . Clockwise rotation
increases level, counter clockwise rotation decreases level. Left balance is selected by
pressing the knob once, and adjusting the level. Right balance is made by pressing the knob
again, and adjusting the level. Pressing the knob once again will bring it back to being a
volume control.
7. To adjust the GAIN of each input ( to match the levels of all the components in the system),
press and hold its selector button while you press the volume knob - then release them both.
The display will switch to "00" and the selected input light will flash.
Turn the volume knob clockwise to raise the input gain up to +18db or turn counter clockwise
to reduce the input level up to -99 db (note that the signs "-"or "+" are not displayed).
To switch back to MAIN, press any button or the knob, or wait fifteen seconds.
