3.2 Limit
This LED indicates an overload in the input channel.
Permanent clipping can result in a defective amplifier.
3.3 Fault
This LED indicates a short circuit of the speaker output, overheating, overload
or an internal error of the amplifier.
4.1 Balanced audio inputs
Connect this input to the audio output of the preamplifier.
The input sensitivity is 385mV / 20k
Ω
.
4.2 100V Speaker outputs
Connect the 100V speakers to this output.
Warning, do not connect any low impedance speakers.
The speaker output is balanced and has floating ground.
The output has no transformer.
Connecting the output to ground or earth must be avoided to prevent
malfunctions.
4.3 Inputs for remote control (only 24V operation)
By shorting pin 7 and 8 of the RJ45 remote control input, you can turn the
amplifier turn on and off.
This function could be used for saving battery power.
4.4 24V DC Inputs
Each channel has a separate 24V emergency power input.
To turn on the amplifier in 24V operation, use the remote control inputs, as
described in point 4.3.
The power switch (6) has no function at 24V operation.
