UHf VHF 1 to 8 Professional Anti Interference Automatic Mute Microphone Set (800MHz-890MHz )

Feature: 1. Adopt multi-stage high performance acoustic filters to provide excellent immunity to interference. The series is equipped with sophisticated filters in both the high-level and first-stage IF amplifier stages. The characteristics of the sound filter of the second IF amplifier stage, by using a ceramic filter with good consistency, obtain a fine frequency selection filter, which greatly demonstrates high anti-interference ability. 2. Professional o output: XLR balanced output and 6.3 unbalanced output. This series of products, all using XLR independent balanced output and 6.3 unbalanced hybrid output coexist, can adapt to various occasions of equipment connection, avoiding confusion and embarrassment caused by device connection mismatch. 3. Automatic mute and engine balance elimination circuit, eliminate off balance machine and other engine noise. This series of products all have automatic mute and balance elimination circuit, clear the switch machine scale, avoid weighing noise and scene noise even damage the o amplitying equipment and speakers. 4. Using highly reliable surface mounting technology(SMT) production. This series of products all use high stability, high relability surface mount components, the use of surface mounting technloy and the applcation of the aging process to detect and elininate the early failure of the components. Compared with the through pin type component, the stability, the reliability and the sevice life of the product are obviously improved. 5. VHF200MHz-270MHz operating frequency, 40Hz-20KHz frequency response, working distance is about 100m.
