AmpliVox SW222 Mono-Stereo, Volume, Microphone Inputs, Auxiliary, Output, Speakers, No Sound

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.
