When connected to the Polycom HDX system, the microphones on the Sound-
Structure by muting the microphones on the Polycom HDX system. As
described in Chapter 6, the HDX will send a mute command to the “Mics”
group whenever the HDX receives a command to mute via the HDX API or via
the HDX IR remote receiver.
Volume Control
Volume control in the room can be accomplished by adjusting the fader con-
trol on the “Amplifier” virtual channel as follows:
inc fader “Amplifier” 1
will increase the gain on the “Amplifier” channel by 1dB and
dec fader “Amplifier” 1
Alternatively the fader settings may be set to an absolute value with the set
command as follows:
set fader “Amplifier” 0
to set the value of the fader to 0dB.
When connected to the Polycom HDX system, the Amplifier fader setting on
the SoundStructure will be adjusted when the volume on the Polycom HDX is
adjusted. As described in Chapter 6, the HDX will send a fader command to
the “Amplifier” group whenever the HDX receives a command to adjust
volume via the HDX API or via the HDX IR remote receiver.
Telephony
The SoundStructure in this example can use the Polycom HDX’s telephony
signal as that is a separate stream that is sent from the HDX to the SoundStruc-
ture device. The telephony system would be controlled with the Polycom HDX
system.
