25OPERATIONOPERATIONPower LEDThe power LED indicates that the AC cord is plugged into a working AC powerreceptacle and that the power switch is in the “On” position.Active LEDThe rear panel turn-on mode switch determines when and how the amplifier willturn on. The “Active” LED indicates that the amplifier is on.Power SwitchThe front panel switch is a master or “vacation” power switch. No matter whichturn-on mode you have selected, the master power switch will turn off allcircuitry—including the sensing circuitry. If you are going on vacation and/orwould like to reduce power consumption while you are away, turn the masterpower switch “Off” (push the rocker switch out). When you would like to returnto normal operation, turn the switch “On” (push the rocker switch in).D.C. ProtectionIn the event a damaging D.C. signal becomes present on any of the speaker termi-nals, the D.C. protection circuit shuts down the entire amplifier and the red LEDlabeled “Protection” illuminates. To reset the amplifier you must turn the frontpanel power switch “Off” and then “On.”Listening at Higher VolumesThirty watts is enough power to play a conventional speaker in a normal sizedroom loudly enough to completely drown out conversation. Even at levels likethat, the SI-1230 will sound clear and clean. However, it requires more powerto achieve a reasonable volume of sound in a large room than it does in a smallroom. It is possible (even if you are not a teenager) to turn the volume so highthat the amplifier runs out of power. This creates “clipping” distortion.
