AmpliVox S222 Leaflet

Page of 2
MONO-STEREO 
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 LINEOUT OUTPUTS. 
 
VOLUME 
Rotate clockwise to increase amplification.   
 
MICROPHONE INPUTS 
There are three microphone inputs, which can be used simultaneously: 
DYNAMIC 
- for standard dynamic cartridge microphones 
CONDENSER  - for electret or condenser microphones which require phantom power  
                                           (Supplied from the amplifier) 
WIRELESS 
- accepts line-level output from wireless microphone receiver if using an S222 
                                 
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 to the input on a tape recorder. 
 
SPEAKERS 
Two separately amplified speaker jacks (4-8 ohms) allows you to use internal speaker and extension speaker for 
additional sound power or true stereo output. 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.
