• UHF800MHz high band to avoid interferences.
• Multiple middle & high band filter to eliminate interferential signal.
• PLL circuit to ensure no interference when using a lot of microphone systems simultaneously.
• Companding technology greatly decreases noise but increases dynamic range.
• Lower feedback function lowers feedback effectively.
• Multiple high band megaphone with quite considerable sensitivity. Multiple noise monitor to enhance anti-jaming function.
• Special designed frequency response produces satisfactory sound of bass-middle-treble.
• Superior power switch for turning ON/OFF the system without noise.
• Best wafer and other components to ensure good sound.
• Auto reception of the signal avoid dead point, overcome discontinuous or unsteady signal in audio output.
• Maximum distance is100m in open field, 50m in normal.
