CHANNEL B VOLUME CONTROL (ADDRESS 04H)
5.5.1 MUTE (MUTE) BIT 7
Default = 0
0 - Disabled
1 - Enabled
Fucntion:
The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output
will be retained. The muting function is affected, similiar to attenuation changes, by the Soft and Zero
Cross bits in the Transition and Mixing Control (address 02h) register. The MUTEC will go active dur-
ing the mute period if the Mute function is enabled for both channels.
5.5.2 VOLUME (VOLx) BIT 0-6
Default = 0 dB (No Attenuation)
Function:
The digital volume control allows the user to attenuate the signal in 1 dB increments from 0 to -90 dB.
Volume settings are decoded as shown in Table 8. The volume changes are implemented as dictated
by the Soft and Zero Cross bits in the Transition and Mixing Control (address 02h) register. All volume
settings less than - 94 dB are equivalent to enabling the Mute bit.
