With positive treble settings, internal clipping may occur even with overall vol-
ume less than 0 dB. This will lead to a clipped output signal. Therefore, it is not
recommended to set treble to a value that, in conjunction with volume, would
result in an overall positive gain.

Higher resolution is possible: an LSB step results in a gain step of about 1/8 dB.
With positive equalizer settings, internal clipping may occur even with overall
volume less than 0 dB. This will lead to a clipped output signal. Therefore, it is
not recommended to set equalizer bands to a value that, in conjunction with vol-
ume, would result in an overall positive gain.
