Function:
The level of the shelving treble gain filter is set by Treble Gain Level. The level can be adjusted in 1.5 dB
increments from +12.0 to -10.5 dB.
Bass Gain Level (BASS[3:0])
Default: 1000 dB (No Bass Gain)
Function:
The level of the shelving bass gain filter is set by Bass Gain Level. The level can be adjusted in 1.5 dB in-
crements from +10.5 to -10.5 dB.
AOUTx Volume Control:
AOUTA (Address 16h) & AOUTB (Address 17h)
AOUTX Volume Control (AOUTX_VOL[7:0])
Default = 00h
Function:
The analog output levels can be adjusted in 0.5 dB increments from +12 to -102 dB as dictated by the DAC
Soft and Zero Cross bits (DACX_SZC[1:0]). Levels are decoded in unsigned binary as described in the table
above.

When the limiter is enabled, the AOUT Volume is automatically controlled and should not be ad-
justed manually. Alternative volume control may be achieved using the PCMMIXx_VOL[6:0] bits.
