INTRODUCTION

The new VM-93C wireless microphone is the second generation of UHF

rechargeable wireless microphone system designed by the engineering team of

Better Music Builder.

VM-93C is designed for both commercial and public use. It is a heavy duty

design including two hand-held microphones with one receiver. Each hand-held

microphone has a total of 32 frequencies. Two microphones together have 64

frequencies. We have set up 32 frequencies for each microphone to make the

frequency selection easily. There is also a separate charger base, which is one

of the best in the market with two microphones in one receiver, to allow the user

to charge the battery at any place. This system is reliable for use by KTV clubs,

restaurants, coffee shops and churches, etc.

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 and battery levels.

3. One receiver has two built-in units (Receiver A and Receiver B).

4. Easy to select channels with pre-set frequencies.

5. Each microphone has 32 channels. There are a total of 64 frequencies in

two microphones.

6. Easy and convenient mounting for portable rack.

7. Adjustable antennas for different angles to receive better signals.

8. A separate charger base is provided.

RISK OF ELECTRIC SHOCK

DO NOT OPEN

Taking apart or modifying the

receiver may lead to electric shock,

fire, or damage to the receiver and

will void your warranty.

THE SYSTEM INCLUDES THE FOLLOWING PARTS

The package comes with one receiver, two transmitters, one charger base, two DC

adaptor, one audio cable, four AA rechargeable batteries, and two antennas.

SETTING UP YOUR RECEIVER

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.

HOW TO SELECT FREQUENCIES

This receiver has two built-in receivers (i.e. Receiver A and Receiver B). The

manufacturer has already pre-set a particular frequency for each channel. To

select the frequency, you can use either Receiver A or Receiver B and press

the upper button for selection. Selectiing frequencies at either Receiver A or

Receiver B will work. You can set up the same channel at both microphones

because the same channel can have different frequencies.

When you set up a particular frequency at Receiver A, you also need to set

the same frequency at the microphone. Please refer to the “Frequency Table”

on page 16.

HOW TO CONNECT AUDIO OUT

There are three different connectors as shown in the following diagram:

• Connector 1 is a channel B XLR-balanced audio out

• Connector 2 is a mixed audio output (Channel A and Channel B)

• Connector 3 is a channel A XLR-balanced audio out

Connector 1 (Channel B) is a balanced XLR audio signal. If you connect B to the

mixer or amplifier, then you can control the microphone effect on MIC. B only.

Connector 2 is an unbalanced 1/4 audio signal. If you connect to Connect 2

(1/4), both MIC. A and MIC. B will mix 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).

Connector 3 (Channel A) is a balanced XLR audio signal. If you connect A to the

mixer or amplifier, then you can control the microphone effect on MIC. A only.

For North America Market using 120V, DC-14~16V 480mA adaptor

For market outside North America using 220V, you may need to change to a

220V~ 240V DC adaptor with a maximum battery capacity of 480mA.

Please make sure to use the right DC adaptor. Otherwise, it may

damage the receiver and the charger because their maximum battery capacity

is different. The product warranty will be void if you use the wrong DC

adaptor.

OPTIONAL: 19” RACK MOUNT KIT

If you want to put the system onto a mount-kit, please follow the below

diagram. Our design has this special feature to allow it to mount on a DJ rack.

It is removable.
