Alternatively, channels 1/2 and 4/5 can be used in bridged output mode; see To wire to A500 Loudspeakers in bridged mode, page 12.

Each channel of the 558 Multi Channel Power Amplifier provides twin outputs for bi-wiring. On speakers that provide separate

connections to the bass/mid and tweeter units this allows the units to be connected independently to the multi channel power amplifier, for optimum sound quality.

Alternatively, for loudspeakers providing a single pair of inputs, either of the output terminals can be used.
