Speaker Wire Connections

CAUTION! All speaker wire connections must be made with the amplifier Off.

INSTALLATION

Bare Wire

Unscrew the red or black plastic knob, insert the bare wire end into the opening, and then tighten the knob until the wire is securely clamped.

Banana Plugs

There are many types of banana plugs, some crimp, some solder. The Niles gold banana plug has a quick-con- nect binding post for the bare wire on the body of the plug. A banana plug is simply inserted into the jack at the end of the ampli- fier’s binding post. Dual banana plugs will fit the SI-245 bind- ing posts.
