Unit speaker is wired internally. Plug external speaker into right speaker jack for stereo. Note: when using a stereo AUX source with a single speaker, only one of the stereo channels will be heard, switch stereo/mono switch to mono for both channels to be heard. However, all MIC inputs are heard equally on both channels. PROBLEM SOLVING FEEDBACK is the howl or screech often heard in sound reinforcement systems. It is caused by sound from the loudspeaker returning to the microphone. AmpliVox systems utilize proven acoustical principles to minimize this; however, there is no way to completely eliminate feedback under conditions of high amplification. If feedback occurs check the following: 1. User’s hand covering the head of the microphone. [Hold microphone under head slots.] 2. Sounds can easily re-enter microphone. Keep loudspeaker turned toward audience. Note: sound can be reflected from a hard surface back through the microphone. [Turn speaker.] 3. User holding microphone in a reflecting position. [Turn microphone.] 4. Volume setting too high. [Reduce microphone channel volume; compensate by speaking louder or closer to the microphone.] NO SOUND Make sure amplifier POWER switch is turned on and red LED is lit. If switch is on and LED is not lit, check to see that batteries are properly connected and at full charge. If using optional power adapter, check to see that front panel connector is properly seated, and verify that the power source is live.
