Operation
Front Panel Controls
Power
The front panel ON/OFF switch applies power to the amplifier and is
illuminated when power is ON.
Input Volume Controls
Each input module may be individually controlled by its corresponding
volume control knob.
MIC2, AUX 1 Mode Switch
Activates the corresponding input that it is switched to, MIC2 or AUX1.
The other input is inactive and any connections to the inactive input will
not work.
Bass and Treble Controls
The Bass and Treble controls are used to adjust the tonal balance of
the amplifier output. The center position of these controls provides flat
frequency response. Counterclockwise rotation of these controls
reduces the bass or treble response, while clockwise rotation increases
such response.
The treble control has a cut/boost range of +/- 11 dB at frequencies
above 10 kHz and provides a roll off after 20 kHz to reduce gain
above the audio range.
The bass control has a cut/boost range of +/- 11 dB at frequencies
below 100 Hz. When driving speakers using the direct-coupled output
terminals, the bass filter’s response is flat to 20 Hz.
