BASSBAND FEATURES

Bass

bit[15:8]

Bass range

60hex

+12 dB

58hex

+11 dB

...

08hex

+1dB

00hex

0dB

F8hex

−1dB

...

A8hex

−11 dB

A0hex

−12 dB

Higher resolution is possible, one LSB step results in a gain step of about

1/8 dB.

With positive bass settings clipping of the output signal may occur. Therefore,

it is not recommended to set bass to a value that, in conjunction with volume,

would result in an overall positive gain.

The settings require: max (bass, treble) + loudness + volume

≤ 0dB

bit[7:0]

Not used, must be set to 0

With positive treble settings, clipping of the output signal may occur. There-

fore, it is not recommended to set treble to a value that, in conjunction with

loudness and volume, would result in an overall positive gain.
