Output connections
The loudspeaker output connections are implemented using 4-pin terminal block (5.08 mm
pitch) connectors for each output.
All outputs contain two (identical) 100V and COM terminals, allowing convenient connection
for two loudspeaker lines.
The table below shows the output voltage, impedance and maximum power load for each
amplifier type in 100 Volt or 8 Ohm output configuration:

PMQ series max output voltage in 8 Ohm output mode
In 100 Volt output mode, numerous loudspeakers may be connected in parallel until the
minimum load impedance for the entire loudspeaker line has been reached. The number of
allowed loudspeakers is depending of the power / impedance of the connected speakers.
In 8
Ω
mode, it is not allowed to connect a load impedance to the output of the amplifier
which is below 8
Ω
