Line Level Audio Input, Cascade Audio Outputs

INSTALLATION

Line Level Audio Input

CAUTION! THE AMPLIFIER MUST BE OFF WHENEVER YOU MAKE CHANGES TO THE INPUT CONNECTIONS.

STEP

1.Label all of the interconnecting cables for the sources they connect to.

2.Connect the sources by inserting the RCA plugs into the amplifier’s jacks.

DESCRIPTION

Use audio patch cables with RCA phono plugs attached to the ends.

Connect outputs from your sources to inputs on the amplifier. Never connect a source or preamplifier’s input (e.g., record inputs) to the inputs of your SI-275.

Cascade Audio Outputs

The "Cascade Audio Outputs" enable you to connect another amplifier to your preamplifier output. The connectors are gold-plated RCA phono jacks. Connect them to another amplifier’s inputs with a standard audio patch cable. The outputs are not buffered; if you wish to daisy-chain more than 5 Niles amplifiers you will need a Niles ADA-6 buffered distribution amplifier. A single ADA-6 will allow you to daisy-chain 5 amplifiers from each of its six outputs, allowing 30 SI-275 power amplifiers to be fed from the same master preamplifier. If your preamp has a vacuum tube output stage, you must use a Niles ADA-6 to drive more than a single SI-275.
