INTRODUCTION
As a leader in the Karaoke market, the engineering team of Better Music Builder
recently designed the VM-82U UHF Wireless microphone system. VM-82U has
two different frequency groups. Group A has 32 different frequencies and Group
B has 1,280 different frequencies, which are authorized for use in United States
by FCC.
One of the outstanding features of VM-82U is that it allows individual and group
singing as well as playing with musical instruments. Our engineering team designs
this unit in such a way that the sensitivity can be adjusted at the transmitter
(hand-held microphone) for singing and playing musical instruments. Therefore, a
high sensitivity is good for playing musical instrument because it can pick up
signals from the musical instrument for high performance. On the other hand, a
low sensitivity is good for singing because it can reduce the noise when holding
the hand-held microphone.
In addition, the dual channel function of the receiver in this unit allows two
microphones to operate at the same time. Therefore, this special feature is good
for duet singing. This single unit is equivalent to two units for the same function
by other brands.
This wireless system may operate on some UHF frequencies that are not
authorized in your area. Please contact the relevant governmental department in
your country to obtain information on the authorized UHF frequencies for the
wireless system in your area.
SYSTEM CHARACTERISTICS
1. Equipped with the latest wireless technology and UHF dual-channel with one
receiver to picks up weak signals and prevents signal interference.
2. Clear LCD screen that can allow you to check AF (Audio Frequency) and RF
(Radio Frequency) signal levels.
3. Receiver Sensitivity can be adjustable from 0 dB to 40 dB for different
environmental conditions.
4. Hand-Held microphone Sensitivity can be adjustable from 0dB to -30dB for
different environmental conditions. For example, -20dB is good for singing
while 0dB (the highest sensitivity) is good for playing muscial instrument.
5. One receiver has two built-in units (Receiver A and Receiver B).
6. Audio signal can cover a distance from 10 feet to 300 feet.
7. Easy and convenient mounting for portable rack.
8. Adjustable antennas for different angles to receive better signals.

RECEIVER LCD PANEL DESCRIPTION
After turning on the “POWER” button, LCD screen will light up as
below:
1. RF (radio frequency) Indicator
2. AF (audio frequency) Indicator
3. Current Channel/Frequency Display: current value depends on your setting.
If there is static or no sound coming out of your speakers, than
there may be a frequency interruption from another system, change your
frequency to match your transmitter’s (microphone) frequency.
4. Mute Indicator: When “MUTE” is displayed, this means that there is no vocal
signal(s) going out. When the microphone is on, “MUTE” would not appear.
5. This unit is in Diversity signal indicator. Either “I” or “II” would appear at the
lower hand corner of the screen.
SENSITIVITY ADJUSTMENT (SQELCH) PROGRAMMING:
1. Keep pressing “SET” until LCD screen
indicates “SQELCH” as shown on the left.
If the microphone is off, but all RF
indicators show signals, it means that you
need to change to different frequency.
2. After 2 to 3 seconds, the screen will
display your current dB settings.
When setting the dB in the receiver,
it has a different function from that of the
transmitter (hand-held microphone). The dB
in the receiver is for distance coverage while
the dB in the transmitter is for sensitivity.
This menu is for adjusting sensitivity, and to
prevent signal interference. The range of
adjustment is 0~40dB. The recommended
value is 20dB. (Manufacture default setting).
The lower the dB the farther away you can
be, but the more interference.

THE SYSTEM INCLUDES THE FOLLOWING PARTS
The package comes with one receiver, two transmitters, one DC power adapter,
one plastic screw driver, one audio cable, four AA batteries, and two antennas.
SETTING UP YOUR RECEIVER
1. Screw the antennas (BNC socket) into the front panel of the receiver in a vertical
90° angle and turn it in clockwise to lock it.
You can adjust the antennas to angle differently for adjusting signal strengths.
2. Insert the DC adapter into the power socket of the rear panel the power
supply must comply the requirement of the system.
3. To turn on, turn Volume to the minimum. Press and hold the power button
for 3 seconds until the LCD screen lights turn on.
4. Adjust the settings to your liking (See the description for the LCD or control panel).
5. To turn off, press and hold the power button for 3 seconds until the power
stop. LCD screen will display “OFF”, then power will automatically shut off.
CHANNEL OPERATION
This unit has dual channel operation (Receiver A and Receiver B). It has 1,280 different
frequencies. For easy operation, our manufacturer designs this unit in such a way that
each receiver (Receiver A and Receiver B) has four different frequencies. Therefore, it
has a total of eight different frequencies from both Receiver A and Receiver B. With
this special feature, you can use the same channel with your microphones.

Once the receiver is on, the RF and AF
would appear in the LCD screens.
Channel A (Left) and Channel B (Right)
have different frequencies.
When the receiver is on, but the
transmitter is off, it is normal that there is
no RF signal. If there is RF signal, there is
interference, change the frequency.
If “BAT” appears with strong signal, it
means that there is enough battery. If the
bar has less than two units, you need to
change the battery.
When the transmitter (i.e. hand-held
microphone or body pack) is not on, but
the receiver LCD screens show RF, it
means that there is interference, so you
need to change the channel.
Figure 7
When the microphone is on, “MUTE”
would not appear on the LCD screen.
Either “I” or “II” would blink at the lower
right hand corner because the unit is in
diversity.
If “BAT” appears with weak signal, it
means that there is not enough battery.
If the bar has less than two units, you
need to change the battery.

For single person use, we
recommend setting the receiver to
the minimum 30 dB because the
hand-held microphone would be
less sensitive.
For musical instruments, we
recommend setting the hand-held
microphone to 0 dB because it
would pick up full quality sound of
the musical instruments.
For group use, we recommend
setting the hand-held microphone
to -10 dB.

RECEIVER SIGNAL INTERFERENCE 1
When you set the receiver to 00 dB, it can cover up to 328 feet (100 meters).
However, there may be interference from other wireless devices. For indoor
use, set the receiver at 35 dB or 40 dB.
Figure 1
For equipment rental setup,
make sure that distance
between the microphone
receiver and hand-held
microphone is appropriate.
Please refer to the table

Please refer to the next table for receiver dB
setup to achieve the best performance. The
sound performance has nothing to do with
the coverage distance. For example, 00 dB
may produce the most interference because
of a distance over 300 feet. If the receiver is
set at 30 dB, it would cover a distance of 100
feet with less interference. It depends on
your need for sound performance.
