9.1 Set the mode dip switch
9. Dip Switch Setting
Set switch upward------------mode1
Set switch downward--------mode2
For mode 1, the BGM and call signal will operate in the internal amplifier of MT-AMP 1000.
The BGM signal will be muted when there is microphone or other higher priority signal is operating.
For mode 2, you can add additional external amplifier at a call power amplifier.
In mode 2, the call signal will go through the call power amplifier to announce on those selected Zones,
and the other Zones, which are not selected during call announcement, will remain to play BGM signal.
9.2 .Set 20KHZ switch.
Set the switch downward, there will 20KHZ pilot tone signal created.
The 20KHZ detecting function will be activated.
The external amplifier acts at standby amplifier (under mode 1) when there is
20KHZ.
As soon as the 20KHZ pilot tone is not exist, it will be taken as abnormal, the
standby amplifier will take over the internal amplifier of MT-AMP 1000The fault
LED will light up.
Set the switch upward, the 20KHZ pilot tone will be OFF.
The 20KHZ detecting function will not work.
