SKM-9900U

Featuring UHF 2-channel diversity dual-reception design, the system supports infrared frequency sync pairing between mic and receiver. It allows simultaneous use of 2 handheld mics, 2 lavalier mics, or a mixed setup with zero interference.
Dual-color LCD displays on transmitter and receiver enable clear status monitoring. Noise lock and digital pilot tone eliminate static and cross-frequency interference, boasting 100m+ (open area)/80m (complex environment) range—extendable to 200m+ with STX series directional antenna amplifier, 5 systems usable concurrently in the same venue.
High-quality wide-frequency cardioid capsule delivers clear natural highs, powerful mids and smooth lows for pro-grade sound performance.
