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 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.
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.
AC pOwER pLUG
STEp
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.
CaUTIon! Do not plug the amplifier's cord into a
preamplifier's convenience outlets.

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-1230.
DESCrIpTIon
if you use a grounded power strip, surge
suppressor or extension cord, verify that proper
ground is maintained.
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.
