PROFESSIONAL POWER AMPLIFIER
A. LOW impedance applications
1. NORMAL STEREO (no led): default setting for normal stereo
operation.
2. CH1 SUB + CH2 TOP (led 1): frequencies below 100 Hz are sent
to the sub channel (CH1). Frequencies above 100 Hz are sent to
the top channel (CH2). Filter slope is fixed: 12 dB/oct or second
order Butterworth characteristic. Audio signal from input 1 is
used.
3. CH 1 linked CH 2 (led 4): Both output channels will amplify the
signal from the CH1 input.
B. 100V applications
4. CH1 TRAFO + CH2 full range (led 2): channel 1 is optimized for
transformer loads, channel 2 is optimized for low impedance
applications.
5. CH1 SUB + CH2 TRAFO TOP (led 1 + led 3): frequencies below
100 Hz are sent to the sub channel (CH1). Frequencies above
100 Hz are sent to the top channel (CH2). Filter slope is fixed:
12 dB/oct or second order Butterworth characteristic. Channel
2 is optimized for transformer loads. Channel 1 input is sent to
output 1, channel 2 input to channel 2.
6. CH1 TRAFO + CH2 TRAFO (led 2 + led 3): both channels are
optimized for transformer loads.
7. CH1 TRAFO linked CH2 full range (led 2 + led 4): channel 1 is
optimized for transformer loads, channel 2 is optimized for low
