Volume Control Module
Example Program
An example program can be obtained from the Downloads section of the Crestron
website (
. Search for ST-VC.SMW. New users are required to
register in order to obtain access to the FTP site.
This example program illustrates control over a ST-VC network device in a
CNMSX-PRO system. In the example, channels A and B are tied together to provide
control over a stereo source that has a left and right channel. Channel C is for mono
source that only has one channel, such as a microphone. The system also has a
FLAT input which will take the bass and treble levels for channels A, B, and C to
50%.
There is a MUTE ALL that simply toggles the MUTE ALL line on the ST-VC.
When MUTE ALL is engaged, the mute states for A, B, and C are disregarded and
all channels are muted. When MUTE ALL is released, channels A, B, and C will
revert to their previous states.
