LX-78II Wireless Microphones
As a home microphone, the best choice for moving coil, because of its sound quality than other types of better, people can truly reproduce the sound of a large and difficult environment in the volume and the occurrence of self-excited howling sound equipment, speaker of the treble damage speaker. Genuine goods are usually packaged, very beautiful design, microphone in hand should feel very comfortable, feel comfortable, screen cast should be no burr, but not damaged. Microphone line microphone should be consistent with a trademark brand. Quite satisfied with the election of their own products, can be a superior quality of imported hi-fi test-machine. Test machine, stereo headphone jack into the microphone, the volume rotation to a minimum, with Random`s CD drive or VCD-player with genuine music, the volume on, open the microphone switch, this time, you will find the microphone into a only a small speaker, you can experiment with different microphones to choose the best sound quality of a. Finally, check the process, that is shaking microphone should not be loose, but not with the microphone off. Access to PA microphone jack, the switch, the microphone should not be "cracking friends" sound, press the switch there should be no noise. After more selective, the microphone can be passed, such a microphone is undoubtedly excellent. The machine uses high-strength aluminum alloy microphone cover net cover design, set with built-in wind sponge, anti-drop performance, and will never rust! !
Main functions:
1 use VHF200-270MHz frequency band to avoid interference frequency
2 using multi-level narrow-band high-frequency and intermediate frequency selective frequency filter, fully eliminate the interference signal
The three pairs microphone design, they both concert
4 handheld microphone with a battery indicator circuit, prompt replacement battery
All quartz oscillator circuit has a very high frequency stability
Using audio compression - expansion technology, noise is greatly reduced, increasing dynamic range
5 has reinfusion howling depression weakened function, can effectively reduce the reinfusion whistle
6 receiver multi-level high-frequency amplifier with high sensitivity
Independent of output and mixed output can be connected to the mixer and karaoke amplifier
7 multiple noise monitoring circuit, so that it has a very strong anti-jamming features
Frequency response specifically designed according to speech features, strong bass IF area bright clear treble
8 perfect switching noise elimination circuit, to avoid huge pulse noise when you turn on the switch, and expensive damage to the speakers or the impact of the program conducted
9 has the best power switch impact noise elimination circuit, so you can not hear the impact of noise in the startup or shutdown completely
