รายละเอียด: ไมโครโฟนไร้สาย UHF wireless systems

MAIN FUNCTION
Using UHF 800MHz band to fixed frequency avoiding frequency jam and noise interference.
Using multilevel high frequency and mid-frequency narrowband filter, so as to dispel any possible interferefering signals.
Lock automatically from preset 16 non-interfered channels, maybe adjust 400 free non-interfered channels.
There is a volt indicating circuit in the microphone. It can tell you if it is necessary to change the battery.
A specially designed circuit switch is on the phone. It is for clearing up waves of miscellaneous signals.
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.
The receiver use multilevel high frequency enlarger, so it has high sensitivity.
It has channel separate outputting and mix output, and it can connected with the sound-adjusting stage and the karaoke enlarger.
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 timbre will be very good.
Longest distance in open: 100m. Ideal distance in open: 60m
Frequency response taibred for vocals, with brightened midrange and brass roll off
Uniform cardioid pick up pattern isolates the main sound source and minimizes background noise
Pneumatic shock-mount system cuts down handing noise.
