pOwER SwITCh
The front panel switch is a master or “vacation” power switch. No matter which
turn-on mode you have selected, the master power switch will turn off all
circuitry including the sensing circuitry. If you will not be using the amplier for
an extended period of time, turn the master power switch “Off” (push button
switch out). When you would like to return to normal operation, turn the switch
“On” (push button switch in).
Important Notes: Equipment is not completely disconnected from main power
source when power switch is in the “OFF” position.
pOwER LEd
The power LED indicates that the AC cord is plugged into a working AC power
receptacle and that the power switch is in the “On” position.
BICOLOR STATUS LEd
The bicolor Status LED illuminates “green” when the amplier circuitry has been
turned on by the Turn-On circuits, and illuminates “red” to indicate activation of
the amplier’s built-in protection circuitry due to either a fault in the wiring or the
speaker, or with the Niles System Integration Amplier
®
itself.
LEvEL AdjUSTmENT SCREwS
The rear panel level adjustment screws allow you to adjust the level of the Niles
System Integration Amplier
®
relative to other ampliers in your system. Use
a 1/8” slotted screwdriver to adjust the screws. If the Niles System Integration
Amplier
®
is the only amplier in your system, leave the screws at their factory
default setting (12:00 position).
CLEANING ANd mAINTENANCE
The internal parts of the Niles System Integration Amplier
®
are electronic
and require no maintenance. Once a year it is appropriate to twist the RCA
connectors on each input to remove corrosion and improve conductivity. You
can clean the amplier with soft cloth or paper towel dampened with water or a
mild detergent. Do not use any spray-type, abrasive cleaners on the amplier.
