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.
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 gage 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 a coin 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.
