FUNCTION INTRODUCTION

Our special wireless microphone system has these characteristics as the following. For many reasons, such as low frequency,
traditional wireless microphones system are easy to be interfered especially because many machines CD, VCD and LD, radiate out
too many harmonic. To solve this problem we design this kind 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.
We also design it special functions (tone key locked identity) to avoid interference from outside.
1.

MAIN FUNCTION

Using UHF 800 Mhz band to avoid interferencing frequency.
Equipped with exquisite LCD panel, to show receiving channels, and operate more easily.
Lock automatically from preset 16 non-intered channels, may be adjust 400 free channels.
All use with UHF PLL circuit, so the frequency is very steady.
With audio compressing-expanding technology, the machine can lower noises and increase the dynamic range.
It can also lower reecho.
Special tone key locked identity functions to avoid interference signal from outside.
Open the mute system.
There are multiple noise detect circuit, multi circuits. So it has strong anti-jamming speciality.
CPU control diversity receiving mode that contributes not only long reception range but eliminates the signal
dropouts and unstable reception.
Choose excellent chipset and high quality component, so that its ringer will be very good.
Longest distance in open: 100m Idealest distance in open: 60m.
Frequency response tailored for vocals, with brighened midrange and bass rolloff.
2. OPERATION OF THE RECEIVER
1. Pull out the antenna A & B, make them be perpendicular with the machine.
2. Power line connection to DC 17V socket.
3. Connection of the audio output: one end of the audio cable into "MIX"socket and other end audio amplifier or
mixer`s "MIC IN" or "AUX IN" socket.
4. Push the power switch, the display of LCD is lighted.
5. When the microphone is working. The receiver output voice, volume of the receiver can be controlled by
