, regardless of whether or not a trigger signal is present. 12V Trigger Input and Output The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trig- ger signal to turn the amplifier on and off. To use this feature the toggle switch must be set to the ON position. This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. The jack labeled OUT is for connecting an- other 3.5mm plug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a +12 volt trigger signal is applied to the IN connector. Protection Circuitry The RB-1070 features a thermal protection cir- cuit that protects the amplifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RB-1070’s protection circuit is indepen- dent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if tem- peratures exceed safe limits. Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop play- ing and the LED indicator on the front panel will light up. If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to iden- tify and correct the problem that caused the protection circuitry to engage. When you turn the amplifier back on, the protection circuit will automatically reset and the indicator LED should go out. In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation lead- ing to an overheating condition. In very rare cases, highly...
