The CVOL command is used to adjust the playback volume on each channel.

It is possible to input the VOL

command regardless of the status of the NCR signal.

The CVOL command can be set for each channel.

The CVOL command allows specifying multiple channels at

one time.

Setting any bit(s) from CH0 to CH3 to “1” sets the playback volume on the corresponding channel(s).

The volume setting is initialized by the AMODE command.
