INTRODUCTION

Intro

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

Featu res

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

Set Up

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.

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

Recommend

balanced XLR connection delivers better quality signal by reducing noise.

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.

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.

TROUBLESHOOTING

Troublesh ootin g

CAUTION: Before troubleshooting any symptoms, make sure equipments are turned OFF.

1. SYMPTOM: NO SOUND

CAUSE: There is no indication of signal.

REMEDIES:

A. Batteries should be inserted correctly. Make sure to follow the polarity of the battery according to the diagram. B. If batteries are inserted correctly and still no power, batteries may be low and should be replaced. C. Microphone and receiver should be in the same channel to allow transmitting and receiving signal. D. Volume is turned to a low level and should be turned to a high enough but comfortable volume level. E. Make sure no wires inside the microphone are loose. If it is, reconnect wires if possible. F. Make sure the microphone is turned ON; not OFF or set to MUTE.

2. SYMPTOM: RECEIVER LCD IS OFF.

CAUSE: Receiver is unpowered.

REMEDIES:

A. Power adapter should be connected properly. B. Make sure the right power adapter is being used. C. Determine whether there is indeed current coming from the power outlet.

3. SYMPTOM: NOISES.

CAUSE: There is interference within your area.

REMEDIES:

A. Make sure user isn’t standing too close to speakers. Standing too close to speakers with microphone will create feedback unless microphone volume is turned down.

Page 14

B. Audio cable of poor quality should not be used. Switching to a cable of higher quality such as a balanced XLR cable can reduce noise. C. Switch to a model that uses a different set of channels when the above remedies do not work.

4. SYMPTOM: DISTORTION IS INCREASING GRADUALLY.

CAUSE: Batteries are running low.

REMEDIES:

A. Replace batteries as soon as possible. B. Make sure batteries have enough power. Even if they are new batteries, they may have lost power during its time being on the store shelves.

5. SYMPTOM: POOR SIGNAL.

CAUSE: Objects can be disrupting communication between receiver and

microphone.

REMEDIES:

A. Make sure no objects are between receiver and microphone, such as walls and shelves. B. Make sure microphone usage is not in perimeter of police, fire or radio stations. C. Devices that send out radio signals can be disruptive, such as cell phones, radios, computers, etc. D. Switch to a model that uses a different set of channels when the above remedies do not work.
