are meant for the connection of condenser type microphones that use 24V phantom
power, dynamic microphones (30-600 ohms) or a high level sound source (e.g. AM/
FM tuner, cassette desk, CD player, etc.). In case you are using it is necessary to use
the switch (26).
Note: Connecting unbalanced microphones to the amplifier when the phantom is
switched on could lead to severe damage on the microphones and is therefore not
recommended. It is absolutely mandatory to perform any plugging or unplugging of
microphone cables with the phantom power turned off. Also, make sure that the phan-
tom power is turned off when using microphones that are not meant to be operated
with phantom power. The voltage is present on pin2 and pin3 of the XLR-connector
could lead to severe damages on the microphones. When in doubt, please consult
the owner’s manual of the questionable microphone or contact your dealer before you
perform any connections.
24. AM Loop Antenna (CA1T Only)
This antenna for receives AM frequency band waves.
25. FM Antenna (CA1T Only)
This antenna for receives FM frequency band waves.
26. INPUT 2, INPUT 3 and INPUT 4 lnputs Sensitivity and XLR
Phantom Power 24V Switch
By turning these switchs to the LINE position INPUT 2, INPUT 3 and INPUT4 can be
connected to an audio source with high level signal output. By turning these switches
to the MIC position the INPUT 2, INPUT 3 and INPUT4 can be connected to a dy-
namic microphone with low impedance. By selecting the switch to the 24V position,
connects the 24V phantom supply on the XLR (pin2 and pin3) of INPUT 2, INPUT 3
and INPUT4. This is necessary to operate condenser type microphones which require
this type of external supply.
It is recommended to use this switch with the master volume set to minimum.
27. lnput Sensitivity Switch (AUX1, AUX2)
By setting these switches onto the “1” position the AUX1 and AUX2 inputs are suit-
able for connecting a CD-player. By setting these switches onto the “2” position the
AUX1, AUX2 input is suitable for connecting an AM/FM radio signal output. By setting
these switches onto the “3” position, the AUX1, AUX2 input are suitable for connecting
to a desktop cassette player signal output. By setting these switches to the “4” posi-
tion, the AUX1, AUX2 input are suitable for connected high-level signal outputs.
28. Telephone Paging Input Level Control
This control allows you to set the volume of the sound source that is connected to the
