OPERATION

OPERATION

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.

Active LED

The rear panel turn-on mode switch determines when and how the amplifier will turn on. The "Active" LED indicates that the amplifier is on.

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 cir- cuitry—including the sensing circuitry. If you are going on vacation and/or would like to reduce power consumption while you are away, turn the master power switch “Off” (push the rocker switch out). When you would like to return to normal operation, turn the switch "On" (push the rocker switch in).

D.C. Protection

In the event a damaging D.C. signal becomes present on any of the speaker ter- minals, the D.C. protection circuit shuts down the entire amplifier and the red LED labeled “Protection” illuminates. To reset the amplifier you must turn the front panel power switch “Off” and then “On.”

Listening at Higher Volumes

Thirty watts is enough power to play a conventional speaker in a normal sized room loudly enough to completely drown out conversation. Even at levels like that, the SI-1230 will sound clear and clean. However, it requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the volume so high that the amplifier runs out of power. This creates "clipping" distortion.
