Vmlz' Set A Zone's Mute Level - Zektor HDA604 User Manual

2=NoMute - This disables muting, but sets the volume level to the current muted level.
+=Toggle - This will toggle the current setting. If muted then unmute, if unmuted then mute.
The '2' (NoMute) option allows the mute setting to be cancelled without affecting the volume level.
Response strings for the 'VZ' and 'VPZ' commands will be sent to indicate the new volume to the
controller. The response string for the 'VMZ' command will be a '0' to indicate muting is now dis-
abled. A '2' will never be returned in the response string.
The VMZ command format is:
^VMZ @zone,@zone,mute$
^VMZ @zone,?$
Response Strings:
^=VMZ @zone,mute$
Where:
= One (or more) zones to be mapped.
@zone
= Mute setting (0=Unmuted, 1=Muted, 2=NoMute).
mute
A value of '2' is never returned by the response string. If muting is disabled by the '2' (NoMute) com-
mand, a value of '0' will be returned to indicate muting is disabled.
Mute fading and the level of muting are all predetermined by the 'VMLZ' and 'VMT' commands. For
instance if mute fading has been previously set using the 'VMLZ' command, then sending the "
" command will cause the volume on zone1 to fade to the muted level.
@1,1$
To toggle the mute setting use the '+' setting:
^VMZ @1,+$

'VMLZ' Set a Zone's Mute Level

The 'VMLZ' setting is the value to be subtracted from the current volume when the mute command is
enabled. This value is the number of 0.5dB steps to be subtracted, for instance a setting of 40 would
subtract 20dB whenever the mute command is enabled. A setting of 248, or above will always do a full
mute.
There are three different ways of muting the volume:
1 Jump immediately to the new mute volume.
2 Fade to the new level in the time given by the 'VMT' command.
3 Fade to the new level using the slope given by the 'VMT' command.
To fade to a new level over a given period of time, add 10000 to any mute level setting.
To fade to a new level at a given ramp speed, add 20000 to any mute level setting.
The format used to jump immediately to a new level is:
^VMLZ @zone,@zone,attn
^VMLZ @zone,+step$
^VMLZ @zone,-step$
^VMLZ @zone,@zone,?$
Response Strings:
^=VMLZ @zone,vol$
