LAMP
Connection for 12 to 15V DC accessory
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 when used with
S132A
AUXILIARY
To add pre-recorded music or sound effects during your presentation, just connect your CD player, tape
player or computer sound card into the AUXILIARY LINE IN jack using a 6’ stereo cable (supplied),
then plug into the phone jack on CD or cassette. 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 a 6’ stereo cable
(supplied), to the input on a tape recorder.
SPEAKERS
Two separately amplified speaker jacks (4-8 ohms) allow you to use one or both speakers for additional
sound power or true stereo output. Base unit speaker is wired internally. Plug external speaker into left
speaker jack for stereo. 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.
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 howlback 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.
