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 control on the "Amplifier 1" and
"Amplifier 2" virtual channel as follows:
inc fader "Amplifier 1" 1
will increase the gain on the "Amplifier 1" channel by 1dB and
dec fader "Amplifier 1" 1
Alternatively the fader settings may be set to an absolute value with the set command as follows:
set "Amplifier 1" fader 0
to set the value of the fader to 0dB. Similar commands can be sent to adjust the volume of "Amplifier 2".
Telephone Functions
The first telephony interface may be taken offhook by sending the command
set phone_connect "Phone 1 Out" 1
and placed on hook with the command
set phone_connect "Phone 1 Out" 0
The telephone may be set to dial the digits 1234567, once taken offhook, with the command:
set phone_dial "Phone 1 Out" "1234567"
Customizing The Phone Routing
If the system has only one telephony caller, the user may wish to have the telephone caller audio come from
both sets of loudspeakers. Assuming the first telephony interface is used if there is only one telephone
caller, this can be accomplished by unmuting the "Phone 1 In" channel to "Amplifier 2" with the following
command.
set matrix_mute "Phone 1 In" "Amplifier 2" 0
When the second line is answered, the routing can be changed to mute the first phone line to the second
amplifier channel as follows.
set matrix_mute "Phone 1 In" "Amplifier 2" 1
No change to the AEC reference would be required as the AEC reference uses both "Amplifier 1" and
"Amplifier 2" and will work whether there is one or two phone lines connected.
