Pcm-Stereo Mirroring Analog Outputs - Zektor HDA604 User Manual

The sources for the HDMI video channel are (see "'HSZ' Set Zone(s) -- HDMI Switch" on page 42):
0 = Disconnect video channel from any source (blanks video).
1-16 = HDMI video from HDMI inputs 1-16.
The sources for the HDMI audio breakaway channel are:
0
1-16
17-48
49-80
81-96
97-112
113-128
129-144
Note: Only SPDIF type audio can be broken away from the HDMI video. This includes Dolby5.1, DTS,
and PCM-stereo. The switch will pass Dolby5.1, TrueHD or DTS Master Audio from an HDMI source
to HDMI zones, but you cannot breakaway, or extract high definition audio to coax outputs.

PCM-stereo mirroring analog outputs

The inputs 129-144 allow the digital outputs to mirror those of the analog outputs.
129 = Mirror analog output 1.
130 = Mirror analog output 2, etc.
For instance if you want the coax output 3 to mirror anything coming out of analog output 1, you
would send the command:
^DSZ @3,129$
After this command, anything playing on analog output 1 will be mirrored to coax output 3. Any input
changes made to analog output 1, will also affect coax output 3. Any volume, tone, etc. changes made
to analog output 1, will also affect coax output 3. Coax output 3 becomes an exact digital copy of what
is coming out of analog 1.
This mirror only works locally on each audio bank. For instance the ProAudio48 has three output
audio banks. Bank one contains the analog and digital outputs 1-16, bank two contains outputs 17-32,
and bank 3 contains outputs 33-48.
In this case, coax outputs 1-16 are mapped as:
129 = Mirror analog output 1.
130 = Mirror analog output 2, etc.
Coax outputs 17-32 are mapped as:
129 = Mirror analog output 17.
130 = Mirror analog output 18, etc.
Coax outputs 33-48 are mapped as:
129 = Mirror analog output 33.
130 = Mirror analog output 34, etc.
On the ProAudio48, the above example:
^DSZ @3,129$
would still mirror analog output 1 on coax output 3, but the command:
^DSZ @19,129$
38
= Disconnect HDMI audio from any source (mutes audio).
= Digital audio extracted from HDMI inputs 1-16.
= Reserved. Mutes audio, same as switching source '0'.
= Digital audio from coax inputs.
= Digital audio from optical inputs.
= Digital audio from the "audio return" inputs on the HDMI receivers.
= Digital audio extracted from HDMI outputs.
= PCM-stereo mirroring analog outputs 1-16.
