Cable and Wire, Tech TIP | Niles Audio SI-275 guide

Cable and Wire

It will be easier to reconfigure or troubleshoot your system in the future if you label the cables and wires for their destination or source, rather than which ter- minal of the SI-275 they are connected to.

The SI-275 connects to your sources via shielded line level audio cables with RCA phono plugs. Use high quality cables with your Niles amplifier for the low- est possible noise and best overall performance. Your Niles dealer can recom- mend the proper cable.

The SI-275 connects to your speakers using 2 conductor speaker wire. For most applications, we recommend you use 16 or 18 gauge wire. For wiring runs longer than 80 feet, we recommend 14 gauge wire. The binding posts of the SI-275 will accommodate up to 12 gauge wire. Larger sizes can be accommodated by attaching banana plugs to the wire. Note that the binding posts accept dual banana or single banana connectors.

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number. The lower the number, the larger the wire, i.e. twelve AWG is physically larger than fourteen AWG.
