• Product range： BM-533 Respective category： UHF ------Product detailed parameter MAIN FUNCTION : 1. Using UHF470-560Mhz band to avert interferencing frequency. 2. Using multilevel high frequency and mid frequency narrowband filter, so as to dispel any possible interferencing signals. 3. Using multilevel high frequency and mid frequency narrowband filter, so as to dispel any possible interferencing signals. 4. The wireless microphone use hidden antenna .look good and are useful 5. There is a volt indicating circuit in the microphone.It can tell you if it is necessary to change the battery. 6. A specially designed circuit switch is on the phone . It is for clearing up waves of miscellaneous signals. 7. All use quartz crystal oscillating circuits ,so the frequency is very steady. 8. With audio compressing-expanding technology ,the machine can lower noises and increase the dynamic range .It can also lower reecho. 9. Particular noise detect to avoid interference from outside open the mute system. 10. Choose excellent chipset and high quality component,so that its timbre is very good. 11. Longest distance in open :50m.Idealest distance in open: 30m 12. It is suitable for stages、ballrooms、auditoria、classrooms and families.
