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.
Using Level Controls as Limiters
If your system is remote controlled, or if you think that some of the users like
to play the stereo too loudly, you can choose to calibrate the system so that it
is limited to a volume level you assign. The SI-1230 allows you to set different
volume levels for different rooms.
Calibrate your system volume levels with the steps outlined below:
1. Lower all of the SI-1230 level controls to the minimum volume position. If
there are any other ampliers in the system, lower their level controls to the
minimum (all of the ampliers in your system must have level controls).
2. Raise all of the individual in-wall volume controls to the loudest setting.
3. Play a loud radio station with the tuner set to Mono.
4. Raise the volume of your preamplier or receiver slowly– if you hear any
sound, lower the volume again and recheck all of your amplier levels, they
must be at minimum. If no sound is heard, proceed to step ve.
5. Have someone step into each room and listen as you adjust each level control
to the desired maximum level for that room. Adjust the balance between
speakers for the most common listening position in each room.
