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

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.

4. Connector 4 is a channel A XLR-balanced audio out

5. Connector 5 is a channel A 1/4-inch unbalanced audio output

both MIC. A and MIC. B will mixed together to produce the same signal. If you

want to produce different effects on MIC. A and MIC. B, you need to connect to

XLR (Connector 1), which is equivalent to channel B, and XLR (Connector 3),

which is equivalent to channel A. You can also adjust different echo or MIC. tone

effects on each microphone (i.e. MIC. A and MIC. B).
