MONO
This application illustrates the basic mono bridging method for all Autotek
amplifiers.
A MONO signal source is required, such as would be available from the mono
sub bass output of an active crossover, whether stand alone, or built into a head
unit or equalizer. Do not be tempted to connect the hot, or positive
outputs, from any source together to obtain a mono signal, as this could very well
damage the output stage of that source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter
RCA cable. Connect the mono speaker positive terminal to the RIGHT -, and its
negative terminal to LEFT +.
- The switch should be in the position and the
should be in the position.
