Listeningfora lifetime
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of
your musical enjoyment. Now it’s time to consider how you can maximize the fun and
excitement your equipment offers. VocoPro and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of your equipment by playing it
at a safe level. One that lets the sound come through loud and clear without annoying
blaring or distortion and, most importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume
of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard
against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.
Taking a minute to do this now will help to prevent hearing damage or loss in the future.
After all, we want you listening for a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often undetectable until it is too late, this manufacturer
and the Electronic Industries Association’s Consumer Electronics Group recommend you
avoid prolonged exposure to excessive noise. This list of sound levels is included for your
protection.
Some common decibel ranges:

Microphone basics
Microphone Position
The UHF-3200 is ideal for close-up vocals and can be held in the hand or mounted on a mic stand. The most
common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a
matter of personal taste, and there is no one “correct” microphone position.
Proximity Effect
When the sound source is less than ¼” from the microphone, the microphone boosts bass frequencies (by 6 to 10
dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known as proximity
effect, happens only in unidirectional dynamic microphones like the UHF-3200.
Feedback
Feedback occurs when the amplified sound from any loudspeaker reenters the sound system through any open
microphone and is repeatedly amplified. Most commonly, feedback is caused by the following conditions: placing
loudspeakers too close to microphones, having too many open active microphones, boosting tone controls
indiscriminately (mainly treble) and performing in areas with high ratios of room surfaces that have hard and reflective
surfaces such as glass, marble and wood. What to do if feedback occurs before the sound system is loud enough?
• Request that the talker speak louder into the microphone.
• Reduce the distance from the talker to the microphone. Each time this distance is halved, the sound system output
will increase by 6dB.
• Reduce the number of open microphones.
• Move the loudspeaker farther away from the microphone. Each time this distance is doubled, the sound system
output can be increased by 6dB.
• Move the loudspeaker closer to the listener.
• Use an equalizer/feedback reducer to cut the frequency bands in which the feedback occurs.
MICROPHONE PLACEMENT & TONE QUALITY
Lead & Backup Vocals
Lips should be less than 3” from or even touching the windscreen on an axis to the microphone. Doing this creates a
robust sound, emphasizes bass and provides maximum isolation from other sources.
Speech
When giving a speech or simply speaking, place the microphone 4” to 10” away from the mouth, just above nose
height for a natural sound with reduced bass. You can also place the microphone 8” to 16” away from the mouth,
slightly off to one side, for a more “distant” sound with highly reduced bass and minimal “s” sounds.
11

Operations
If you will be using the UHF-3200 with stage monitors and/or P.A. system, try the following:
• Place the stage monitor directly behind the microphone.
• Locate the P.A. loudspeakers so that they point away from the rear of the microphone. (With the speakers located
in these positions, the possibility of feedback is greatly reduced).
• Always check the stage setup before a performance to ensure optimum placement of microphone and monitors.
IMPORTANT: Every wireless microphone installation is a unique situation, and can present a variety of problems.
Never attempt a live performance without first conducting a “walkthrough” test of the system in the performing area.
If major changes (additional wireless systems or intercoms, relocation of scenery, etc.) have been made since the last
walk-through test, check the wireless system again, as close to performance time as possible.
OPERATIONS
1. Press the POWER button on the UHF-3200 receiver’s front panel. The power LED on the receiver will be RED.
2. Adjust the receiver’s VOLUME controls to approximately 50%.
3. Switch the microphone’s POWER BUTTONS to the ON positions.
4. Talk or sing into the microphones. During normal operation, the Signal Indicator LED’s will light YELLOW when a
microphone is being used.
5. Adjust the receiver’s VOLUME controls until the output levels are balanced with each other and other possible
source output i.e. CD+G tracks.

Troubleshooting
PROBLEMS
SOLUTIONS
No sound; receiver RF light(s) and mic(s) not lit.
Make sure POWER switches on transmitters and
receiver are set to ON positions.
Check microphone batteries to ensure they are
providing power.
Replace or charge batteries if necessary.
Check receiver's AC power connection.
Make sure antennas are in the microphones' line of
sight.
If necessary, reduce the distance between the
microphones and reciever.
No receiver sound but the RF lights are glowing.
Turn up the receiver's VOLUME level controls.
Check for proper connection between receiver and
external amplifier/mixer.
Talk into the mic and observe the receiver's RF signal
LEDs. If they glow, the problem is elsewhere in the
sound system.
Received signal is noisy or contains interference with
transmitter on.
Check microphone batteries and charge or replace if
power is low.
Remove local sources of RF interference, such as
lighting equipment. Two transmitters may be operating
at the same frequencies or frequencies which are too
close in proximity. Turn one off or exchange for one
with a different frequency. Signal may be too weak. If
so, reposition antenna (If possible, move them close to
the transmitter).
Noise coming from the receiver with the mics turned
OFF.
Remove local sources of RF interference, such as
lighting equipment.
Reposition the receiver or antennae.
Momentary loss of sound as transmitter is moved
around performing area.
Reposition receiver and perform a "walkthrough" test
and observe the signal strengths. If audio droppouts
persist, mark these "dead spots" in the performing
areas and avoid them during the performance.
Battery running low even after recharging.
Replace rechargeable batteries (rechargeable
batteries have a life of 500 hours of charging and
recharging).
