INTRODUCTION
If you’re looking for simplicity, look no further! The Better Music Builder
VM-52U G2 Wireless Microphone is as streamlined as it gets without hindering
performance. It requires no setup as it is ready to go out of the box. Its light
weight design features dual wireless microphones and balanced XLR audio
signal to improve sound quality.
VM-52U G2 Wireless Microphone features Clear Voice, delivering crystal
clearer sound quality that pro audio engineers trust. Gone are unpleasant
artifact noises wireless microphones are known to emit. What you get is a
cleaner, clearer sound at all audio levels.
With years of experience designing wireless microphone system, we at Better
Music Builder understand the problem with short battery life. Through intensive
research we have developed a better power management system to help
extend our wireless microphone battery life.
Its predecessor VM-52U was our best-selling wireless microphone and we
believe VM-52U G2 will do the same.
SYSTEM FEATURES
1. Equipped with the latest wireless technology and UHF dual-channel in a
2-in-1 Base Module to pick up weak signals and prevent signal interference.
2. Clear LCD screen displaying Frequency, Channel, Audio Frequency and
Radio Frequency.
3. Clear Voice delivering crystal clearer sound just like a wired microphone.
4. No setup required.
5. 6~8 hours of battery life.
6. Light weight mounting design for portability.
7. Adjustable antennas for better signal receiving.
8. AA battery usage for easy handling.

HARDWARE SETUP
HOW TO CONNECT AUDIO OUTPUT:
There are three rear outputs as shown in the below diagram:
MIXED OUTPUT is unbalanced audio output for MIC 1 & MIC 2 using 1/4”
connection. When using this output, MIC 1 and MIC 2 have to share a signal. To
produce different effects on each microphone, MIC 1 and MIC 2 need their own
signals which can be done by using XLR connections.
MIC 1 BALANCED OUTPUT is balanced audio output for MIC 2 using XLR
connection. When using this output, you can change MIC 2 effects without
affecting MIC 1 effects.
MIC 2 BALANCED OUTPUT is balanced audio output for MIC 2 using XLR
connection. When using this output, you can change MIC 2 effects without
affecting MIC 1 effects.
UHF WIRELESS SYSTEM DIAGRAM:
Set Up
We highly recommend using balanced XLR connections if the distance between the
microphone receiver and the amplifier/mixer is more than 10 feet. The grounding of the
balanced XLR connection delivers better quality signal by reducing noise.

HOW TO CONNECT DC-POWER:
For North America Market, use 120V, DC 14~22V 500mA adaptor. For market
outside North America, use 220V~ 240V DC adaptor with a maximum battery
capacity of 500mA.
OPTIONAL 19” RACK MOUNT KIT:
To put the system onto a mount-kit, please follow the diagram below. Our
special design allow it to be mounted on a DJ rack.
NOTE
Please make sure to use the right DC adaptor. Otherwise, it may damage the 2-in-1 Base
Module and the charger because their maximum battery capacity is different. The product
warranty will be voided if there is damage caused by using the wrong DC adaptor.
