BOMGE 210U Wireless Dual Channel Professional Cordless Microphone System

I .FUNCTION INTRODUCTION

Our special wireless microphone system has these characterstics as the following For many reasons,such as low frequency,tradional wireless microphone system are easy to be interfered especially because many professinal wireless CD,VCD,and LD,erad-iate out too many harmonic.To solve this problem we design this kind professinal wireless microphone . We adopt aseries of measures to improve its functions,advance frequency,using multievel high frequency and mid frequency narrowband rilter,mulriple noise detect and control.

II. MAIN FUNCTION

l  Usin UHF 640-690 Mhz band to avert interferening frequeny

l  Using mueve high equency and m euny rowand ter so o disp any poss be

interferencing signals

l  The wireess microphone look good and are useful

l  There is a volt indicating out in the mio ooe t can to you if t is necessary to change the battery

l  A cally designed iut with s n the phone s or eaing u was of miscellanous signal

l  All use quartz crystal oscilating circuits so the frequency is very steady.

l  th ad comessnxandn ecology e machine can wr noses and ncrease the damic

range. lt can also lower reecho

l  Partcular noise detect to avoid interference from outside open the mute system

l  Choose excelent chipset and high quality component, so that its timbre is very good

l  Longest distance in open: 80m. dealest distance in open: 50m

l  It s sultable for stages ballrooms auditoria, classrooms and famiies

 III．OPERATION OF THE RECEIVER

 1. Pullout antenna A&B, make them be perpendicular with the machine

 2. Power line Connection to DC 9-15V socket

 3. Connection of the audio output One end of the audio cable into"AUDIO OUT socket and

 other end audio amplifier or mixers"MIX In or"AUX In socket

 4. Push the power switch, the power-indicating ight is lighted

 5. When the microphone is working the SIGNAL ght the recelver s lighted, The receive

 output voice lume of the receiver can be controlled by adjusting the volume mob

 Attention when you install of the receiver

 It should be more than 1m high from the foor.

 It should be more than 1m beyond the wall

 Antennas should be put out fully, Otherwise It ll infuence receiving signals

 IVOPERATION OF THE MICROPHONE

 1. Open the battery box, then put in the battey

 Attention: The polarity should be night.

 2. Tum on the microphone the ght does nit twinkle or is always lighted you should check

 the battery if the voltage is enough or the battery is well arranged

 3. Tum the mute swetch to middle the recevier will cut out audio output and control noises

 through it.
