4 OPERATION switch
This switch is used to select the operation
mode of the amplifier.
• STEREO position:
The amplifier can be used as a stereo
amplifier.
• MONO (Lch) position:
Amplifies the signal input from the left side
only. Set to this position and make bridged
connections to use as a high-power
monaural amplifier. (The input right signal is
not output.)
3 FILTER switch
This switch allows to apply high-pass or
low-pass filtering to the speaker outputs.
• HPF (High-Pass Filter) position:
The filter outputs the band of higher
frequencies than the frequency set with the
HPF FREQUENCY control.
• OFF position:
The entire bandwidth is output without
filtering.
• LPF (Low-Pass Filter) position:
The filter outputs the band of lower
frequencies than the frequency set with the
LPF FREQUENCY control.
The speaker output is automatically turned
monaural (L+R) and the bass boost function
is activated.
