Slide switch; determines how the input signals C and D are processed. In the lower switch position, the signals are fed
separately to the power amps. In the upper switch position, the signals are added and fed as a mono sum signal to
the power amps. The connection of the power amps is set by the push-button (13).
11 Push-button for switching the operating mode of the power amps for the output channels A and B.
n
Push-button not pressed: Input signals A and B (connection depends on the position of switch
[M1]
(8)) are being
amplified 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 (3). Wiring of the NL4 output sockets: Plus terminal 1+,
minus terminal 1–.
n
Push-button is pressed: Both power amps operate in ‘Bridge’ mode like one power amplifier with double output
power. Input signals A and B (connection depends on the position of switch
[M1]
(8)) are being amplified. The
output signal is present only at output A, the volume is controlled by the control for channel A (3). Wiring of the
NL4 output sockets: Plus terminal = 1+, minus terminal = 2+.
