Function:
The level of ADCX can be adjusted in 1.0 dB increments as dictated by the ADCx Soft and Zero Cross bits
(SOFTx & ZCROSSx) from 0 to -96 dB. Levels are decoded in two’s complement, as shown in the table
above.
Note:
ADCx Mixer Volume Control: ADCA (Address 0Eh) & ADCB (Address 0Fh)
ADCX Mixer Channel Mute (MUTE_ADCMIXX)
Default: 1
0 - Disabled
1 - Enabled
Function:
The ADC channel X input to the output mixer will mute when enabled. The muting function is affected by
the SPEX Soft and Zero Cross bits (SPEX_SZC[1:0]).
ADCX Mixer Volume Control (ADCMIXX_VOL[6:0])
Default = 000 0000
Function:
The level of the ADCX input to the output mixer can be adjusted in 0.5 dB increments as dictated by the
SPEX Soft and Zero Cross bits (SPE_SZC[1:0]) from +12 to -51.5 dB. Levels are decoded as shown in the
table above.
