LINE IN L+R (SEPARATE-COMBINED) 
Combines the separate left and right AUX LINE IN channels. This combined signal will be amplified 
and appear on both the LEFT and RIGHT channels of the SPEAKER and LINE OUT OUTPUTS
 
AUXILIARY
 
To add pre-recorded music or sound effects during your presentation, just plug your CD player, tape 
player or computer sound card into the LINE IN jack.  Separate VOLUME and TONE control knobs let 
you balance the program source with the live microphones. If using an external wireless receiver, for best 
sound quality it should be connected to the LINE IN jack. 
 
OUTPUT 
To tape record your speech or program, connect the LINE OUT on the amplifier (using cable with 
standard 3.5mm plug) to the input on a tape recorder.  
 
SPEAKERS 
Two separately amplified speaker jacks allow you to use one or two speakers for additional sound power 
or true stereo output. Note: when using a stereo
 
AUX source with a single speaker, only one of the stereo 
channels will be heard. However, all MIC inputs are heard equally on both channels. 
 
ANTENNA 
Jack for wireless antenna.  (Antenna supplied on ‘C’ Channel for mounting on either side of amplifier or 
use Velcro for optional mounting locations.) 
 
INTERNAL WIRELESS RECEIVER(on right side of case) 
Power on and off and Frequency A-B switches. Frequency should match wireless transmitter. 
 
PROBLEM SOLVING 
HOWLBACK
 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 howlback under conditions 
of high amplification.  If howlback occurs check the following: 
1.   User’s hand covering the head of the microphone.  [Hold microphone under head slots.] 
2.   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.] 
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.
