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 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 LEDs illuminate “green” when the amplier circuitry for the
respective channel has been turned on by the Turn-On circuits, and illuminates
“red” to indicate activation of the amplier channel’s built-in protection circuitry
due to either a fault in the wiring or the speaker, or with the SpeakerCraft
System Integration Amplier
®
itself.
CLEANING AND MAINTENANCE
The internal parts of the SC16-50 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 amplier.
