9BSST FIVE CHANNEL POWER AMPLIFIER

6. Output binding posts

The RED binding post is connected to the amplifier output. Connect to this post the (+) terminal on the loudspeaker. The BLACK binding post is connected to signal ground. Connect to this post the (-) terminal on the loudspeaker.

When the polarity switch is set for 0 degrees (normal operation ) the output at the RED binding post is in phase with the input signal.

When the polarity switch is set for 180 degrees (inverted operation) the the output at the RED binding post is 180 degrees out of phase with the input signal.

The Output binding posts provide three different interconnect options. Combinations may be used when bi-wiring. See fig- ure 2 below. Cables should be kept as short as practical and should never be terminated with connectors that may become confused for AC power connectors. Cables should be dressed away from input and power cables.

1. Banana plugs offer a quick disconnect option. Before inserting a banana plug into the binding post be sure to tighten the post nut to avoid rattling and to provide full insertion of the banana plug. Gold plated locking banana plugs are available from Bryston.

2. Spade lugs provide high contact area and secure fastening. Lugs should be gold plated. See diagram for details. Post diameter is 5/16’ ( 8mm ),lug width 5/8” (16 mm). Gold plated spade lugs are available from Bryston.

3. Stripped bare wire up to 3 gauge can be inserted through the hole in the binding post and held in place by tightening the post knob. Additional tightening pressure can be achieved using the wrench provided in the slots of the knob. Do not over tighten or the binding post may become damaged. Note that copper wire is malleable and may require further tightening after the initial installation.
