Description DUAL HANDHELD WIRELESS MIC SET It is an advanced high quality wireless microphone system. UHF frequency transmission for higher frequency stability and far transmission distance. Infrered frequency 200 channels, multiple systems can be used simultaneouuly. This system is adopted much imported from integrated circuit components and high quality two-sided circuit board. With the newest didital pilot technology, it maximum avoid fault frequency and string frequency. Multi-level optimization of audio processing program has a graceful sound,plenty of low frequency,prominent medium frequency and intensive high frequency. Built-in the most advanced and the fastest ARM processor and AD/DA chip.Frequency response is at 30Hz-18KHz.It can one key scan field of spatial spectrum quickly and select the cleanest channel,keep you away from interference and crosstalk. Specially designed for stage and karaoke(KTV),fits for auditorium and teaching.
