. Using the VHF200-270MHz frequency to avoid frequency interference.
. Using multilevel high frequency and middle frequency narrowband filter,so as to dispel any possible interference signals.
. There is a volt indicating circuit in the microphone.It can tell you if it is necessary to change the battery.
. All use quartz crystal oscillating 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.
. With the decreasing back-output whistle function,it can decrease the whistle efficient.
. The receiver using multilevel high-frequency to magnify,it is provided with very high sensitivity.
. Adopt pilot tone & noise mute; improve anti-disturbance function for full equipment.
. Ultra-wide frequency response caused by strong bass and crisp,bright treble performance.
. The tonality is quite good with the excellent crystal and component.
. The use of maxumum distance of 80 meters,an ideal distance of 50 meters.
