EIA standard metal chassis equipped with a green backlit LCD screen and electronic buttons on the front panel. The LCD screen will automatically turn bright to identify “Working” or “Standby” mode. The most reliable 24 MHz narrowband high dynamic range receiving circuit greatly decreases intermodulation distortion and increases interference-free compatible channels. Industry’s first “PiloTone & NoiseLock” circuits and the RF interference warning indicator for proper adjustments of the SQ level to avoid interference. MIPRO Auto Scan and ACT™ function provides the transmitter’s frequency with precise and rapid sync to the receiver. There are 7 preset groups with a total of 80 pre-saved frequencies. The user-defined group allows users to choose 8 working channels from 961 available frequencies. Each channel has separate audio output and 3 switchable output gains, or mix signals from all channels with just one output jack. All is to ensure the microphone operates within proper sensitivity and dynamic range, free from distortion. Antenna connector provides bias for MIPRO antenna systems to boost reception distance and signal. External AC 100 – 240 V switching power supply to ensure stable operation of the system even under drastic voltage change. All are designed and made in Taiwan to ensure high quality and value.
