Wireless Microphone
 


FEATURE:

  • BUILT IN RECHARGING UNIT FOR 9V BATTERY
  • Using VHF 170~270 MHz band to avert interference frequency.
  • Using multilevel high frequency and mid frequency narrowband filter, so as to dispel and any possible interference signals.
  • All audio of quartz crystal oscillating, have very high frequency stability.
  • With audio compressing-expanding technology, the machine can lower noise and increase the dynamic range
  • With the function of aborting the noise of feedback, it can effectively reduce the screechy.
  • A specially designed circuit switch is on the phone. It is for clearing up waves of miscellaneous signals.
  • The inside circuit which can eliminate the noise of switch on/off blocking any noise when you switch on or off, also to protect your expensive speaker.
  • Uniform cardioids pickup pattern isolates the main sound source and  minimize background noise.
  • effective, Built -in spherical wind and pop filter.
  • Selected the good crystal and components which make the timbre more clear.
  • Longest distance in open 100m. Idealist distance in open 50m.
