| 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. |
