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 SpeakerCraft Multi-Channel Amplifier itself.
CLEANING ANd mAINTENANCE
The internal parts of the SC12-30 are electronic and require no maintenance.
Once a year it is appropriate to twist the RCA connectors on each input to
remove any oxidation and improve conductivity.
You can clean only with dry cloth. Do not use any spray-type, abrasive cleaners
on the amplifier.
