MPA-45 (320-2035) Connections Faxback Doc. # 15122 CONNECTING MICROPHONES Use the MIC 1 and MIC 2 jacks to connect one or two microphones to the amplifier. The microphone(s) can be high- or low- impedance and must have a 1/4-inch-6.35mm plug. CONNECTING A TURNTABLE Connect a turntable to the amplifier's L and R PHONO jacks. Connect your turntable's ground wire (usually black or green) to the amplifier's GND screw to void hum. CONNECTING AN AUXILIARY SOUND SOURCE Connect an auxiliary sound source, such as a tape deck or a tuner, to the amplifier's L and R AUX jacks. CONNECTING POWER You can power your amplifier from standard household AC power. To connect the amplifier to power, plug the supplied AC cord into any standard outlet. Your amplifier's fuse (located on the amplifier's back panel) protects your amplifier from voltage surges. If the power indicator does not light when you press POWER, check the fuse. If the fuse is blown, replace it with the supplied spare fuse or an identical 1-amp, 250-volt fuse (CA: 2-amp, 250- volt fuse). Be sure you unplug the power cord before you replace the fuse. To replace the amplifier's fuse, use a Phillips-head screwdriver to unscrew the fuse holder. Then, remove the fuse holder, replace the fuse, and replace the fuse holder. (SP/all-06/28/95)
