The Master Volume Control (MVC) provides gain or attenuation to a digital
|
||
|
|
signal path. It can be used in input or output signal path for per-stream
|
||
|
|
volume control or it can be used as master volume control. The MVC block
|
||
|
|
has one input and one output. The input digital stream can be mono or
|
||
|
|
multi-channel (up to 7.1 channels) stream. An independent mute control is
|
||
|
|
also included in the MVC block.
