Description

Nice little PA amplifier. Has connections for a 4ohm - 16ohm speaker, and two mic inputs and then a single aux/phono input. Those are untested, not sure how they are designed to work with only one rca each. For the speakers, if you're connecting a single speaker you use the "common" and "8 ohm" terminals on the rear panel (or whatever ohms it is). With multiple speakers, you need to figure out the total impedance and use the appropriate terminal. In series, impedances add. Two 8 ohm speakers in series would total 16 ohms, so you use the common and 16 ohm terminals. In parallel, the total impedance drops. Two 8 ohm speakers in parallel total only 4 ohms. You need to figure the total impedance of the speaker configuration and connect accordingly. I have lots of other electronics, check out my other ads.
