Bad Output • Is the associated level knob (if any) turned up? • If it's a left main out, try unplugging the RCA left tape output. If the problem goes away, its not the mixer. • If a left speaker is presumed dead, switch the left and right cords, at the mixer's main outs. If the left speaker is still not working, it's not the mixer. Noise • Turn the channel level knobs down, one by one. If the sound disappears, it's either that channel or whatever is plugged into it, so unplug whatever that is. If the noise disappears, it's from your whatever.
