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 (AmpliVox S1600 or equivalent)

LINE IN L+R (SEPARATE-COMBINED)

Combines the separate let 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

If you desire 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. The LINE IN also has its own VOLUME and TONE control knobs, so that you may adjust the volume and tone to the appropriate level.

OUTPUT

If you desire to tape record your speech or program, (using cable with standard phono plug) connect the LINE OUT on the amplifier to the input on the tape recorder.

SPEAKERS

Two separately amplified speaker jacks (4-8 ohms).

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 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 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 front panel connector is properly seated and verify that the power source is live.
