[A-B]
Slide switch; determines how the input signals A and B are processed. In the [O] position, the signals are amplied in
‘stereo’ mode and separately fed to outputs A and B. The volume for output A and output B can be controlled sepa‐
rately with the controls for channel A or B. Wiring of the NL4 output sockets: Plus terminal = 1+, minus terminal = 1–.
In the [On] position, the signals are added and fed as a mono sum signal to the power amps. Both power amps
operate in ‘Bridge’ mode like one power amplier with double output power. The signals of inputs A and B are ampli‐
ed. The output signal is present only at output A, the volume is controlled by the control for channel A. Wiring of the
NL4 output sockets: Plus terminal = 1+, minus terminal = 2+.
