PROBLEM SOLVING
HOWLBACK is the howl or screech often heard in sound reinforcement systems. It is caused by sound from the loudspeaker re-
turning to the microphone. AmpliVox systems utilize proven acoustical principles to minimize this; however, there is no way to com-
pletely eliminate howl back under conditions of high amplification. If howl back occurs, check the following:
User’s hand covering the head of the microphone. [Hold microphone under head slots.] Sound 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.]
User holding microphone in a reflecting position. [Turn microphone.]
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.
