CONTENTS

When outputs A and B, or C and D are bridged, the loudspeaker is connected to +1 and -2 of the

connector see diagram below.

Looking at the rear of the amplifier the right hand Speakon has both channel A and B outputs, the left

hand Speakon channels C and D. This configuration is useful for bridging and bi-amp operation (see

bridged mono operation on page7).

Speakon. . (Quad or Bi-amp)

Never connect either output terminal to ground or to some other output or input terminal (see

warnings in chapter 1)

For normal four-channel operation, connect each loudspeaker load across the output's positive and

negative terminals. Pay attention to loudspeaker polarity; loudspeakers connected out of polarity

degrade sound quality.

Keep the loudspeaker cables as short as possible and use good quality stranded cable. Do not use

shielded wire, such as microphone or guitar cable. Remember that the speaker cable reduces the power

of the amplifier in two ways:

It increases the load impedance and introduces resistive power losses.
