Audio Control
@ 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’ Non-PCM Digital audio Routing
The ClarityAudio cannot mix down non-PCM audio, this is any non-PCM stereo audio bitstream, and
includes Dolby5.1, DTS Audio, and all other types of multichannel audio.
Any time non-PCM audio is detected on a digital input, the analog audio inputs are routed to the ana-
log outputs.
This command allows you to decide what data to send to the digital coax output when surround sound
audio (non-PCM audio) is detected on a digital input.
You can choose to send the surround sound audio as is, this assumes you have a receiver that can
decode surround sound audio, or you can choose to ignore the surround sound audio and instead, con-
vert the analog audio to digital (PCM audio) and send it out the digital output.
This command also doubles as the source selection command when running the switch in the “Classic”
mode. In the classic mode no auto-detection is done, and this command is used to select between ana-
log and digital audio sources, for each of the Coax outputs.
Command format:
^DRZ @ zone,@zone,routing Set the non-PCM routing option.
Response Strings:
^=DRZ @ zone,routing$
Where:
@ zone = One (or more) zones to be affected.
routing = Routing flag.
0 = Non-PCM, digital audio (such as Dolby5.1) is routed, as-is, to the digital output.
1 = Analog audio is converted to digital, and routed to the digital output.
‘LSZ’ Set Lip Sync delay for a Zone
Each zone is capable of delaying audio for up to 170.65mS. The delay resolution is 1/48000 of a sec-
ond, or 48 counts per millisecond.
Command format:
^LSZ @ zone,@zone,delay Set the lip sync delay of a zone or zones.
^LSZ @ zone,+step$ Add ‘step’ to zone’s delay.
^LSZ @ zone,-step$ Subtract ‘step’ from zone’s delay.
Response Strings:
^=LSZ @ zone,delay$
Where:
