INTRODUCTION
Better Music Builder is proud to introduce the newest member in our UHF
wireless microphone systems: the VM-62U. It features a lighter design that
includes two hand-held microphones with built-in LCD panels, Wireless Infrared
Auto Sync System, and ultra long battery life.
Created for novices and professionals alike, VM-62U Wireless Microphone
improves your performance and simplifies your setup. Innovations such as the
Wireless Infrared Auto Sync System make setting up frequencies quick and
simple. Using the technology, the microphone automatically sets the same
frequency as the base module by syncing to create a complete interference free
and crystal clear microphone system. It 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.
The VM-62U Wireless Microphone is arguably the smartest microphone in the
market right now. The base module has a built-in automatic frequency search
capability that picks up the strongest signal in your current environment, saving
you time scrolling through channels hoping for the best signal.
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.
It is simply the best solution for home and professional karaoke performance.
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, Radio
Frequency, Lock Setting, and Antenna Status.
3. Wireless Infrared Auto Sync System makes syncing a breeze.

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 1 using XLR
connection. When using this output, you can change MIC 1 effects without
affecting MIC 2 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 mixer is more than 10 feet. The grounding of the balanced XLR
connection delivers better quality signal by reducing noise.

Please make sure that the other hand-held microphone is turned off when adjusting the
frequency on one microphone.
Each unit is fully tested and qualified by the manufacturer. However, due to the nature of wireless
connection, interference may occur because of local environments and/or radio signals emitted
by other wireless devices within the household.
If MIC 1 or MIC 2 is actively picking up RF and/or AF signal when the handheld microphone is
turned off, this is an indication that the frequency is being used by some other active device within
a 200 feet radius. Therefore, selecting a different frequency is highly recommended.
NOTE
2. MANUAL FREQUENCY SELECT
STEP 1: Press and hold the ACT button on the receiver for three seconds until the
frequency starts flashing, and then release the button.
STEP 2: While it is flashing, press the ACT or SCAN button on the receiver to
choose the desired frequency. After choosing the desired frequency, wait until it
stops flashing.
STEP 3: Press the UP or DOWN button on the microphone to match the receiver
frequency and then press the SET button on the microphone to confirm. When
the microphone frequency matches the receiver frequency, the receiver’s RF bars
will show.

HOW TO ADJUST SQUELCH
The SQUELCH knob on the back of the receiver adjusts the distance range
between the microphone and the receiver. Use a plastic screwdriver to make the
squelch adjustment at the button. A higher level of squelch allows the usage of
microphone further away from the receiver. However, the drawback of using a
higher level of squelch is the increased chance of interference.
HOW TO LOCK/UNLOCK THE RECEIVER
Press and hold the SCAN button on the receiver for more than three seconds to
lock/unlock the frequency on the receiver.
HOW TO LOCK/UNLOCK THE MICROPHONE
STEP 1: Press and release the SET button on the microphone to see “LOC
ON/LOC OFF” on the LCD screen.
STEP 2: Press the UP/DOWN button to either lock or unlock the
frequency/channel of the microphone.
STEP 3: Press the SET button to confirm. Press the SET button again to return to
the main menu.
