connections.

 

 

 

STEP

DESCRIPTION

 

 

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

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

2.Connect the sources by inserting the RCA plug into the amplifier’s jacks. NOTE: If you are using two amplifier channels in “bridged” mode connect the input cable to the even numbered amplifier input jack.

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-1230.

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 AVDA-3 buffered distribution amplifier. A single AVDA-3 will allow you to daisy-chain 5 amplifiers from each of its six outputs, allowing

30 SI-1230 power amplifiers to be fed from the same master preamplifier. If your preamp has a vacuum tube output stage, you must use a Niles AVDA-3 to drive more than a single SI-1230.

STEP

DESCRIPTION

1.Plug the female IEC socket of the supplied AC power cord (the supplied power cord is designed for 120V AC wall outlets), or use an appropriate IEC AC power cord to match the electrical wall outlet you are using (e.g. 240V AC), into the IEC receptacle on the rear of the amplifier.

If you use a grounded power strip, surge suppressor or extension cord, verify that proper ground is maintained.

CAUTION! Do not plug the amplifier’s cord into a preamplifier’s convenience outlets.

The SI-1230 draws a maximum of approximately 890 watts from an AC wall outlet. This is much more than the typical accessory outlet on the back of a component will provide. Use the SI-1230’s auto turn on circuitry to turn on the SI-1230 whenever the preamp is on.
