Zektor Switch Serial Protocol, Version 0.16, 5/13/16
Overview
The ProAudio16 (AUD1600) native source numbering
In the native I/O mode, the sources for the analog audio zones are:
0
= Disconnect zone from any source.
1-16
= Analog audio from RCA left / right inputs.
17-32
= PCM-stereo audio from Coax inputs (mutes if Dolby5.1 or DTS).
33-48
= PCM-stereo audio from Optical inputs (mutes if Dolby5.1 or DTS).
The sources for the digital audio zones are:
0
= Disconnect zone from any source.
1-16
= Reserved. Mutes audio, same as switching source ‘0’.
17-32
= Digital audio from Coax inputs.
33-48
= Digital audio from Optical inputs.
49-64
= PCM-stereo that mirrors the analog outputs.
Note 1: For a complete description of inputs 49-64 see: “PCM-stereo mirroring analog outputs” on
page 38.
Note 2: Only PCM-stereo type audio can be down-converted to analog audio. You cannot down-con-
vert Dolby5.1 or DTS.
The ProAudio32 & ProAudio48 (AUD3200, AUD3248) native source numbering
In the native I/O mode, the sources for the analog audio zones are:
0
= Disconnect zone from any source.
1-32
= Analog audio from RCA left / right inputs.
33-64
= PCM-stereo audio from Coax inputs (mutes if Dolby5.1 or DTS).
65-72
= PCM-stereo audio from Optical inputs (mutes if Dolby5.1 or DTS).
The sources for the digital audio zones are:
0
= Disconnect zone from any source.
1-32
= Reserved. Mutes audio, same as switching source ‘0’.
33-64
= Digital audio from Coax inputs.
65-72
= Digital audio from Optical inputs.
81-96
= PCM-stereo that mirrors the 16 analog outputs of the same audio bank.
Note 1: For a complete description of inputs 81-96 see: “PCM-stereo mirroring analog outputs” on
page 38.
Note 2: Only PCM-stereo type audio can be down-converted to analog audio. You cannot down-con-
vert Dolby5.1 or DTS.
