Connecting the stereo power amplifier

Rear panel

The diagram below shows the rear panel connections.

Outputs

The output terminals should be connected to loudspeakers of 4Ω to 15Ω, using either banana plug or bare wire connections.

Each channel of the 555 Stereo 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 stereo power amplifier, for optimum sound quality.

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