While listening with the stereo headphones, switch the MONITOR
switch between INPUT and OUTPUT to hear the difference between
the original and processed audio, respectively. Normally, the
MONITOR LEFT and RIGHT pushbuttons are kept pushed in, but
either (or both) can be pushed out at any time to listen only to either
the left or right channel audio, or to mute all headphone audio. You
may make the following adjustments to the processor at any time:
1. To freeze all adaptive filters in the process, switch the
ADAPT/FREEZE switch to FREEZE. To allow the adaptive
filters to adapt to changing signals, switch to ADAPT.
2. To bypass all digital filters, allowing the original unfiltered
audio to pass through to the LEFT and RIGHT ANALOG
OUTPUTS and S/PDIF digital OUTPUT RCAs, switch the
PROCESS/BYPASS switch to BYPASS. To filter the audio,
switch to PROCESS.
3. The AUX switch is programmed to have one of the following
functions when switched to AUX:
a. No effect at all (default)
b. Input Limiter IN
c. Input HPF IN
d. Output AGC IN
e. Output HPF IN
f.
Right channel Adapt/Freeze (ADAPT/FREEZE switch
used for Left channel only)
g. Filter 2, 3, and 4 Adapt/Freeze (ADAPT/FREEZE switch
used for Filter1 only)
When switched to OFF, the AUX switch always has no effect on
the signal.
4. To clear all filters, press the CLEAR button. This will
cause all adaptive filter coefficients to be reset to
zero, allowing them to re-converge anew (assuming
the ADAPT/FREEZE switch is in ADAPT).
