OPERATION

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 amplifier 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 amplifier circuitry has been turned on by the Turn-On circuits, and illuminates “red” to indicate activation of the amplifier’s built-in protection circuitry due to either a fault in the wiring or the speaker, or with the Niles System Integration Amplifier ® 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 amplifiers in the system, lower their level controls to the

minimum (all of the amplifiers 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 preamplifier or receiver slowly– if you hear any sound, lower the volume again and recheck all of your amplifier levels, they must be at minimum. If no sound is heard, proceed to step five.

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.
