¡¼??PSM-400 IEM System¡½DGNOG PSM-400 referecmce shure PSM-300 as the design standard, each channel mono, with 32 switchable frequency points per channel to achieve operation without environmental interference.
¡¼??Transmission Distance¡½- The transmitter power is 100MW, and the transmission distance is over 120 meters. Suitable for band combinations, small and medium-sized stage performances.
¡¼??Two Channels¡½- UHF dual-channel wireless audio transmission, providing high-fidelity listening effect, The receiver uses 2 AA battery to power, can work for 8-9 hours
¡¼??Audio Sampling¡½- DSP digital audio compression and expansion, using 48KHz audio sampling rate, to reduce the noise in the wireless transmission system to the best.
¡¼??Excellent material¡½- The transmitter is an all-metal body with a very cost-effective ABS material panel, In order to wear relaxed,the receiver uses all ABS Material.
