AUX OUT
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
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
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.
If using an external wireless receiver, for best sound quality it should be connected to the
LINE IN
jack.
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 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 power
source is live.
