Volume Control
Volume control in the room can be accomplished by adjusting the fader con-
trol 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 tele-
phone 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
