With inferred frequency and 200 channels, multiple systems can be used simultaneously. This system has adopted much imported from integrated circuit components and high quality two-sided circuit board. With the newest digital pilot technology, its 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, keeping you away from interference and crosstalk. Specially designed for stage and karaoke(KTV), fits for auditorium and teaching. Key Features Dual Handheld Microphone 2 Channel Receiver Variable Frequency
