Features 1. UHF wireless in-ear monitoring system. 2. A built-in limiter circuit for stage performances and a wide range of sounds eliminates distortion at excessive input levels. 3. Metal panel and body shell, makes it sturdy and durable 4. Provides desktop-level monitoring in an in-ear monitoring and receiving system with a wireless range from 80 to 100m, and a frequency range of 550-580MHz. 5. The signal-to-noise ratio of the dynamic range is improved, so that the system has excellent anti-interference ability, and once again shows the good original sound. Transmitter Specifications 1.
