With positive bass settings, internal overflow may occur

even with overall volume less than 0 dB. This will lead to

a clipped output signal. Therefore, it is not recom-

mended to set bass to a value that, in conjunction with

volume, would result in an overall positive gain.

Loudspeaker channel: Bass and Equalizer cannot work

simultaneously (see Table: Mode Tone Control). If

Equalizer is used, Bass and Treble coefficients must be

set to zero and vice versa.
