INSTALLATION
Line Level Audio Inputs
Caution! The amplifier must be off whenever you make changes to the input con-
nections.
Cascade Audio Outputs
The "Cascade Audio Outputs" enable you to connect additional amplifiers to your
preamplifier's output. Connection is accomplished with standard RCA interconnect
cables. The outputs are not buffered; to daisy chain more than five Niles amplifiers
you will need a Niles AVDA-3 buffered distribution amplifier. A single AVDA-3
enables you to daisy chain five amplifiers from each of three outputs. This allows 15
SI-1260 power amplifiers to be fed from the same master preamplifier. If your pre-
amplifier has a vacuum tube output stage, you must use a Niles AVDA-3 to drive
more than one SI-1260.
AC Power Plug
STEP
1. Correctly label the interconnecting
cables coming from each source.
2. Connect the sources by inserting the
RCA connectors into a BusMatrix ™
input or dedicated input jack on the
SI-1260's rear panel.
NOTE: When you are using two ampli-
fier channels in the "bridged" mode,
assign the audio signal to be ampli-
fied to the EVEN numbered amplifier
channel using the BusMatrix
™ Dip
Switches.
DESCRIPTION
Use audio patch cables terminated with
RCA connectors.
Connect outputs from your source compo-
nents to the input jacks on the amplifier.
NEVER connect a preamplifier or source
input (e.g., record inputs) to the SI-1260
inputs.
STEP
1. Plug the SI-1260’s attached 2 prong
power cord into a correctly grounded
120 Volt, 60-Hz wall outlet.
CAUTION! DO NOT PLUG THE SI-1260'S
POWER CORD INTO A PREAMPLIFI-
ER'S CONVENIENCE OUTLET.
DESCRIPTION
If you use a grounded power strip, surge
protector, or extension cord, verify that the
proper ground is maintained
1. The SI-1260 draws a maximum of about
890 watts from an AC wall outlet. This is
much more than the typical accessory
outlet on a component's rear panel can
provide.
2. Use the SI-1260's auto turn-on circuitry
to switch "ON" the SI-1260 when the
preamplifier is "ON".
