[B-C]
Slide switch; determines how the input signals B and C are processed. In the [O] position, the signals are fed sepa‐
rately to the power amps. In the [On] position, the signals are added and fed as a mono sum signal to the power
amps.
[C-D]
Slide switch; determines how the input signals C and D 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
separately 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+.
