CAUTION! The amplier must be off whenever you make changes to the input
connections.
CASCAdE AUdIO OUTpUTS
The “Cascade Audio Outputs” enable you to connect another amplier to your
preamplier output. The connectors are gold-plated RCA phono jacks. Connect
them to another amplier’s inputs with a standard audio patch cable. The
outputs are not buffered; if you wish to daisy-chain more than 5 Niles ampliers
you will need a Niles AVDA-3 buffered distribution amplier. A single AVDA-3
will allow you to daisy-chain 5 ampliers from each of its six outputs, allowing
30 SI-1230 power ampliers to be fed from the same master preamplier. 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. 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.
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.
