set mute “Mics” 1

will mute all the microphones in the system and

set mute “Mics” 0

will unmute the microphones in the system.

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.
The volume control range can be limited by setting a fader max and fader min

as shown in the API syntax below:

set fader max “Amplifier” 10
set fader min “Amplifier” -10

to limit the maximum and minimum user range of the fader control to +10 and
-10dB respectively. The max and min ranges only need to be set once and can

be configured as part of the SoundStructure Studio configuration file. If the

current amplifier fader setting is outside of this range, the range of the maxi-

mum or minimum fader values will be adjusted to include the current fader

setting.

Telephone Functions

The telephone interface may be taken offhook by sending the command

set phone_connect “Phone Out” 1

and placed on hook with the command

set phone_connect “Phone Out” 0

The telephone may be set to dial the digits 1234567, once taken offhook, with

the command:

set phone_dial “Phone Out” “1234567”
