interference )
Product description :
Selected & large diaphragm condenser capsule 14 , with a very
good sound quality and frequency response , the use of solid -lock
patch separation structure , ensuring high reliability and stable
performance , is the ideal equipment for demanding high-level
meeting of the project. exclusive design of new base, wide
frequency response , clear sound and transparent, low noise, the
microphone ON / OFF long life, high resistance to squelch touch
switch , the microphone is turned on, the sound head work lights up
red , goose neck and the base can be separate type, suitable for
large, medium and small -type meetings, public communication,
classes , lectures and other occasions.
Key Features:
* Use UHF500-900MHz band PLL frequency synthesizer PLL applications
, the frequency is adjustable, 8 sets can be used simultaneously ,
undisturbed .
* Total control of the central processor integrates the CPU , with
digital LCD screen display , easy operation , superior performance
.
* Multi-level narrow-band high-frequency and intermediate frequency
selective frequency filter, fully eliminate the interference
signal.
Expansion of audio compression technology , greatly reducing noise
, increase dynamic range .
Reinfusion howling suppression has diminished function, can
effectively reduce transfusion whistle .
The receiver uses multi-level high-frequency amplification , with
high sensitivity.
Multiple noise monitoring circuit , tone lock TONE-LOCKED ad hoc
system , so that it has unparalleled anti-jamming features.
Excellent chips and quality components , making the machine
excellent sound quality .
