‘MXI’ Stereo to Mono Down Mix for an Input
Stereo audio can be mix in a number of different ways. This includes swapping channels, and a number
of ways of creating mono audio.
Command format:
^MXZ @
zone
,@
zone
,mix
Set the stereo mix down of a zone or zones.
Response Strings:
^=MXZ @
zone
,
mix
$
Where:
@
zone
= One (or more) zones to be affected.
mix
= Stereo mix down flag.
0 = No change to audio.
1 = Swap left and right channels.
2 = Mix to mono by adding left and right channels.
3 = Mix to mono by using the left channel for both outputs.
4 = Mix to mono by using the right channel for both outputs.
5 = Mix to mono by subtracting the right channel from the left.
6 = Mix to mono by subtracting the left channel from the right.
‘DRZ’ Digital audio Routing
This command allows you to use a coax output as an independent digital audio switch, or to connect it
to the analog output of its associated zone.
When used as an independent switch, the ‘DSZ’ command is used to switch between all the digital
sources. All digital audio is passed through the switch untouched. This includes Dolby5.1 and DTS
audio. You cannot switch the coax output to any analog audio sources.
When connected to an associated analog zone, the setting of the ‘DSZ’ command is ignored, and all
analog audio from the associated analog zone will be converted to PCM stereo and sent to the coax
audio output.
The associated analog zone for each coax is the matching analog zone number. Coax output 1’s associ-
ated zone is analog output 1. Coax 2, associates with analog output 2, etc.
Command format:
^DRZ @
zone
,@
zone
,
routing
Set the digital routing option.
Response Strings:
^=DRZ @
zone
,
routing
$
Where:
@
zone
= One (or more) coax zones to be affected.
routing
= Routing flag.
0 = Coax output is an independent digital audio zone set by the ‘DSZ’ command.
1 = Coax output is connected to its associated analog audio zone
For example, to use Coax output 1 as digital routing zone, send:
^DRZ @1,0$
; Set the digital output up as a digital audio zone.
You can now use the ‘DSZ’ command to route audio from any digital source to coax output 1:
^DSZ @1,17$
;Set the digital output 1 to coax source 17.
