80 dB \nS/N Ratio > 106 dB(A) \nT.H.D. Single-Channel Diversity EIA standard 1/2U metal rack-mountable receiver. Stable PLL circuit. Auto Scan function allows quick search for an interference-free working channel from 112 preset channels under 10 groups. Up to 8 channels in group 11 can be saved and recalled within 961 user-defined frequencies. World’s first ACT function provides precise and rapid frequency sync to the transmitters. Advanced diversity technology for optimum reception range reduces signal dropouts and the “PiloTone & NoiseLock” dual-squelch circuits prevent noise interference. Backlit LCD is lit in green indicates the receiver is in working mode when it detects an incoming signal or buttons are touched. The display dims automatically when the receiver is idle for about 10 seconds. Balanced XLR/unbalanced 1/4" audio output jack, output level switch and DC input are on the rear panel. One mixed-output switch is available for dual-channel receivers. Industry’s only RF interference warning indicator for proper adjustments of the SQ level. Increase sensitivity to extend receiving range; decrease the sensitivity to reduce interference. Receiver provides bias for booster where MIPRO antenna systems can be added for extended receiving range and stability. DC input jack accepts 12~15V power supply.
