INTRODUCTION
Better Music Builder VM-93C G3 Wireless Microphone is certainly the most
innovative model we’ve ever had! Equipped with the latest 2.4 GHz wireless
technology, the sleek system features heavy duty UHF dual-channel
microphones, Wireless Auto Sync System technology, and for the first time ever
uses lithium-ion battery for extremely long battery life.
Built for professional entertainers, the VM-93C G3 Wireless Microphone is
packed with the newest technologies and innovations to improve your
performance and simplify your setup. The built-in Wireless Auto Sync System
makes setting up frequencies a breeze. Using the technology, there is no need
to manually adjust the microphone’s frequency. With a touch of the button, the
microphone automatically sets it to create a complete interference free and
crystal clear microphone system.
Clear Voice technology is pure genius. It enhances the sound of the vocal by
detecting and eliminating artifact noises, thus creating crystal clearer sound. The
result is a sound closer resembles that of a wired microphone. What you get is
a cleaner and clearer sound at all audio levels.
With years of experience designing wireless microphone system, we at Better

battery, commonly used in today’s portable electronics such as mobile phones
and computer laptops. It is simply the best solution for home and professional
karaoke performance!

HARDWARE SETUP
HOW TO CONNECT AUDIO OUTPUT:
There are four audio outputs as shown in the below diagram:
1. MIC 2 BALANCED OUTPUT is balanced audio output using XLR connection.
The grounding of the balanced XLR connection delivers better quality signal by
reducing noise.
2. MIC 2 UNBALANCED OUTPUT is unbalanced audio output using ¼ inch
connection.
3. MIC 1 BALANCED OUTPUT is balanced audio output using XLR connection.
The grounding of the balanced XLR connection delivers better quality signal by
reducing noise.
4. MIC 1 UNBALANCED OUTPUT is unbalanced audio output using ¼ inch
connection.

We highly recommend using balanced XLR connections if the distance between the
microphone receiver and the mixer is more than 10 feet. The grounding of the balanced XLR
connection delivers better quality signal by reducing noise.

HOW TO CONNECT AC-POWER CORD:
For the North America market, use AC 120V 60Hz POWER CORD. For market
outside North America, use 220V~240V.
NOTE
Please make sure to use the right AC Power Cord. Otherwise, it may damage the 2-in-1
Base Module or the CHARGER BASE because their maximum battery capacity is different. The
product warranty will be void if there is damage caused by using the wrong AC Power Cord.

CONTROLS AND FUNCTIONS
1. INTERCHANGEABLE MICROPHONE HEAD
2. POWER BUTTON: Turns the microphone ON/OFF. Holding the button for
5 seconds to initiate syncing process with the receiver.
3. LITHIUM-ION BATTERY: Unlike any other microphones in the market today,
the VM-93C G3 uses lithium-ion battery (the same battery used on iPhone)
for a longer battery life.
CONTROLS AND FUNCTIONS: RECHARGEABLE CHARGER
3. CHARGER BASE INDICATOR: Red light indicates that the battery is being
charged. Green light indicates that the battery is fully charged. It takes
approximately 6 hours for a full charge.
4. POWER SUPPLY: For the North America market, use POWER CORD with
