All using quartz crystal oscillating circuits,so the frequency is very steady. Dual channel designed,two microphones can use at the same time to sing without any disturbing caused by. Microprocessor control, that's easy to operation Using the latest dielectric filter of the RF,to avoid those interferencing signal from band outside Using twice mixer high-frequency circuit design,it has very high sensitivity. about 3 uV Multilevel quiet control circuit,to avoid interference signal from outside open the mute system Special design companding circuit,strongly improve s\n ratio Special voice compress-limiter design,it will not crack though the singer sang very loudly. Using excellent dynamic cardioid direct cartridge,the timbre bright and clear. Choose high quality component,accurate rational circuit design,reliability is enhance high efficiency batteries consumption design, so the handheld could be in using for 20 hours continuously.(AAAbatteries) The space availability is more than 60 meters at the clearing . exquisite streamline aspect ,make holding more comfortable. It is suitable for small and large stages,ballrooms,auditoria,classrooms and families.
