Stereo Operation
(XPA 3004)
In stereo mode, the amplifier can operate four speakers or four speaker groups independently of each other.
The highest output power during is achieved by connecting 4
Ω
speakers. With 8
Ω
speakers the output
power will be slightly reduced. Set the operating mode selector switch to
STE
.

Parallel Operation
(XPA 3004)
In parallel operation, channels 1 and 2 and channels 3 and 4 respectively receive the same input signal. A
signal at the input of channel 2 and channel 4 is ignored. The volume is separately adjusted for all outputs.
This way, PA amplification can provided e.g. for several rooms using the same mono signal while adjusting
the volume independently. Set the operating mode selector switch to
PAR
.
