Bass and Treble Controls
The Bass and Treble controls are used to adjust the tonal balance of the ampli-
fier 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.
