The command for lowering the zone 1 master by 1 step looks like this:
DEC VOLUME ZONE 1 (followed by a <CR> command)
The unit replies:
VOLUME ZONE 1 -1 U E
The volume of zone 1 has been lowered by 1 step. The “U” means that the zone 1 master is unmuted
(not muted). The “E” means that the mute command is enabled. This means that you can send a
mute command.
NOTE: you can increment or decrement (INC or DEC) the volume in steps from 1 to 10. For example,
you want to decrease the master fader level of zone 1 by 10 steps at once. The command looks like
this:
DEC VOLUME ZONE 1 10
Where the “10” can be a value from 2 to 10. If no value is specified, the unit will change by 1 step.
