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-connect 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 amplifier’s binding post. Dual banana plugs will fit the SI-2125 binding posts.

STEP	DESCRIPTION
1. Label all wires.	If you label the wires for their destination,
	rather than which terminal of the SI-2125
	they are connected to, it will be easier to
	reconfigure your system in the future.

2.Connect one stripped wire end or banana plug to the black terminal and one to the red terminal.

CAUTION- Avoid even a single strand of wire touching the chassis or another connector.

A. Split the speaker wire insulation so that at least two inches of each conductor are separated.

B. Strip one half inch of insulation from the end of each conductor of the speaker wire

C. Attach banana plugs or twist the strands of wire together and insert them into the appropriate binding post.
