5.1 Configuring the amplifier
Two audio sources can be connected to the symmetrical XLR jacks (13). If a microphone is
connected, the corresponding jumper must be configured accordingly.
If phantom-fed microphones are used, a 40 V phantom voltage can be added.
Input IN3 (12) is exclusively designed for devices with Line level and cannot be configured
with the jumpers.
In the standard configuration, input IN1 is for “microphone” with phantom voltage, input IN2
for “Line IN” without phantom voltage.
If you want to alter the standard setting,
first pull the plug out of the wall outlet
and then
remove the device cover and configure the device according to the following directions:

* With phantom voltage switched on,
do not
connect a microphone or a Line-IN device with
an unbalanced jack - this could otherwise result in damage to the device!
