NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 1-760-710-0992
16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
INSTALLATION
BUS MATRIX™ LINE LEVEL AUDIO INPUTS
CAUTION! THE AMPLIFIER MUST BE OFF WHENEVER YOU MAKE CHANGES TO THE
INPUT 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.
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-1650.
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. If your preamp has
a vacuum tube output stage, you must use a Niles AVDA-3 to drive more than a
single SI-1650.
AC POWER PLUG
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. Replace the fuse in the bay below the power
cord inlet with one of the 10A fuses provided if using a
220-240V outlet.
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-1650 draws a maximum of approximately
1600 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-1650’s
auto turn on circuitry to turn on the SI-1650
whenever the preamp is on.
