1. The CH SELECTOR set of buttons selects the input source.
2. The MONO button commons the left and right channels.
3. The MONITOR button switches in a recording device (tape deck, CD-R, etc.).
4. The PROCESSOR button switches in a audio processor (surround sound
processor,equalizer, ect.).
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, andlevel changes occur in 1dB increments.
FOR BALANCE ADJUSTMENT: In the window next to the number display are three
iindicator 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
lleft balance level. In the RIGHT mode (red LED) the display readout shows right
balance level. In addition the display will flash on and off 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.
