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
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)
