ER-2040 Professional Wireless In-Ear Monitoring System, UHF with Multiple Receivers for Small Concerts and Stage Performances

Product introduction

UHF system, with high quality traditional circuit design, stronger signal, effective distance up to 300M under the open stage without cover. sound quality updated, better sound reproduction of SR2050 type. New operating system, automatic search for non-interference frequency function, using FM frequency synchronisation, more convenient to use.40 groups of frequencies can be adjusted between 572Mhz to 603Mhz.LCD display shows clear working status, beltpack receiver low battery reminder. Independent power switch control for the transmitter, with ports on both sides of the machine for easy setup. Electronic adjustable volume function, metal receiver and metal transmitter. This wireless monitoring system is used for stage performances and sound broadcasting, and can replace traditional complex sound monitoring equipment to achieve amazing monitoring effects. Using the latest high-frequency transmission and audio signal dynamic processing technology, it also improves the signal-to-noise ratio in the dynamic range, giving the system optimum interference immunity and re-presenting the perfect original sound.
