'MZ' Mute (Disconnect) Zone(s) -- Audio Switch
This is the command used to mute, or disconnect a zone from any source. When audio is muted, the
sound is turned off. When video is muted, video is turned off, leaving a black screen. (Or possibly blue
screen, depending upon how your receiver acts when video has been turned off.)
The different forms of the MZ command are:
^MZ @zone,@zone,mute$
^MZ.ch @zone,mute$
^MZ.ch @zone,+$
^MZ ?$
^MZ @zone,?$
^MZ.ch @zone,?$
Response Strings:
^=MZ @zone,mute$
^=MZ.ch @zone,mute$
Where:
= One (or more) zones to be mapped.
@zone
mute
= Mute setting (0=Unmuted, 1=Muted).
= Channel bitmap (Range 1-3).

'MZ' Examples
The 'MZ' command in its simplest form:
^MZ @1,@3,1$
mutes all channels of the zones '1' and '3'. You can also mute/unmute multiple zones using a single
command. For instance:
^MZ @1,1,@3,@5,0$
mutes zone '1', and unmutes zones '3' and '5'.
By appending a '.' and a channel bitmap to the 'MZ' command, the command can also be used to mute
individual channels.
Currently the only channel available to the Audio switch is channel '2'.
'MZ' Query Examples
There are two forms of the query response string, depending upon whether any channel breakaway
options are in affect.
For instance if HDMI video, digital audio, and HDMI audio, are all muted on zone '1', then:
^MZ @1,?$
would respond with:
^+$
^=MZ @1,1
