General Description

Thanks for purchasing this products. Please read this instruction carefully before using the system so that you can make sure in detail by the numbers how to install,
operate and safeguard the system.
Our wireless microphone system has characteristics as the following. For many reasons, such as low frequency, traditional wireless microphone system are easy to be interfered, especially because many machines, CD, VCD and LO, eradicate out too many harmonic. To solve this problem. We design this kind of true diversity professional wireless microphone. We adopt a series of measures to improve its functions, advance frequency, using multilevel high frequency and mid frequency narrowband filter, multiple noise detect and control.

Product Feature

1. Adjustable dual channel UHF wireless system, 200 channels can be selected.
2. The infrared frequency-locking frequency is locked. The receiver uses dual LCD screens to display the working status of the system.
3. The receiver and the transmitter use IR infrared frequency synchronization technology to synchronize code with one button.
4. Professional performance-level phase lock circuit. Good for karaoke and singing.
5.  Back light LED display indicates RF and AF signal strength, battery status, channel indication (A/ B), frequency, channels etc. 6.Using “Audio Compression and Expansion” patent technology. Has excellent dynamic response and excellent sound quality.

Troubleshooting  

Problem
No sound: Channel not glowing.	• Make sure the transmitter and receiver POWER switches are ON. • Check battery. • Check receiver squelch setting. • Check receiver antenna connection(s). • Make sure antennas are in line of sight of transmitter.
No sound: Indicator and audio level mater lights glowing.	• Turn up receiver audio VOLUME control. • Check for proper connection between receiver and karaoke unit. • Talk into microphone and observe receiver audio level lights. If they glow, the problem is elsewhere in the sound system.
Received signal is noisy or contains extraneous sounds with transmitter on.	• Check battery. • Remove local sources of RF interference. • If using a guitar or other instrument, check connections. • Two transmitters way be operating on the same frequency. Locate and turn one off. • Signal may be too weak. Reposition antennas. If possible, move them closer to transmitter.
Noise from receiver with transmitter off.	• Adjust receiver squelch control. • Remove local sources RF interference. • Reposition receiver or antennas.
Momentary loss of sound as transmitter is moved around performing area.	• Reposition receiver and perform another walkthrough test and observe the RF indicators. If audio dropouts persist, mark these dead spots in performing area and avoid them during performance.
