Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
A - 92
Description
This parameter selects the index of the audio source for the corresponding
cr_mic_in or sr_mic_in physical channels. The index required for this
parameter indicates to which physical channel of the virtual channel this parameter
will be applied. For example, indices 1 and 2 correspond to the left and right physical
channels of a stereo virtual channel.
The value of this parameter indicates the index of the audio source type
(mic_source_type) that will be routed to the physical channel.
When mic_source_type is analog, this parameter has no effect.
When mic_source_type is clink_mic, the value of this parameter indicates which
ConferenceLink mic element will be routed to the physical channel.
For example, assume a virtual channel has been defined like this:
vcdef "Stereo Clink Mic" stereo cr_mic_in 1 2
And the source type has been set to clink_mic like this:
set mic_source_type "Stereo Clink Mic" clink_mic
Then we issue these commands:
set mic_source_index "Stereo Clink Mic" 1 5
set mic_source_index "Stereo Clink Mic" 2 6
These commands set the left and right channels of the "Stereo Clink Mic"
virtual channel to use the 2nd and 3rd elements of the 2nd ConferenceLink
mic.
Examples
mic_source_type Select Mic audio Source type
Command Response Description
get mic_source_index
'Ceiling Mic 1 A' val mic_source_index
'Ceiling Mic 1 A' 1 Queries which microphone index of the microphone array
is associated with the virtual channel 'Ceiling Mic 1 A'.
Since 'Ceiling Mic 1 A' is the first element of the digital
array microphone, the value 1 is returned.
get mic_source_index
'Ceiling Mic 2 B' val mic_source_index
'Ceiling Mic 2 B' 5 Queries which microphone index of the microphone array
is associated with the virtual channel 'Ceiling Mic 2
B'.Since 'Ceiling Mic 2 B' is the second element of the
second digital array microphone, the value 5 (=3+2) is
returned.
