7. FILTER MODE
SUB WOOFER
FULL RANGE
This is for seriate operation per channel sub woofer, x-over
will not be operated.
Permissible adjustment of low cut.
Variable frequency(50~160Hz) by one volume.
Specification of filter -12dB/octave is for subwoofer speaker
mainly.
X-OVER(BI-AMP)
Permissible power supply to input "A" channel connect woofer
speaker to the "CHA" and connect high range speaker to the
"CHB".
It designed -24dB/octave variable frequency.(50Hz~2.5kHz)
LOW CUT
This is to protect speaker from damage by large ultra frequency
or blowing of voice coil, low it designed -12dB/octave variable
frequency.(10~200Hz)
6. MONO OUTPUT
Output connector supplying input CH"A, B" balanced output
connector.
It is convenient to use for sub woofer speaker only.
LIMITER SWITCH
This switch is for grounding between circuit ground and chassis
ground to avoid problems like a electrical potential difference.
When the audio signal drives the amps output circuit beyond
its power capability it clips flattening the peaks of the waveform.
The clip limiter detects this and quickly reduces the gain to
minimize the amount of overdrive limiting occurs only during
actual clipping. Each channel has its own clip limiter and you
can switch it on or off independently.
