Parallel Operation
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. For this operating mode, set the DIP switches
MODE 3 and 4
to their upper
position. Note: At channel 1 and channel 3, it is possible to take off the signal of channel 2 and channel 4
respectively from pins 2+/2-.
Bridge Operation
In bridge mode, channels 1 and 2 and channels 3 and 4 are bridged and therefore provide higher power than
a single channel. Thus, the voltage at the outputs of channel 1 and channel 3 is doubled and subsequently
the output impedance. A signal at the input of channel 2 and channel 4 is ignored. The volume is adjusted
together for both outputs with the control of channel 1 and channel 3. For this operating mode, set the DIP
switches
MODE 1 and 2
to their upper position. Note: In bridge mode, the output signal is provided at pins
1+/2-.
Connection to the Mains
Finally connect the device to the mains with the mains cable. The ON indicator lights up.
