| This series of products is an infrared automatic frequency matching, two channel adjustable frequency multi-channel wireless conference microphone, with 32 frequency points to choose from. The product adopts UHF frequency PLL phase locking technology with less noise interference, and the frequency points increase by 1MHz. The perfect anti noise interference characteristics are unmatched by any similar system. The standard chassis is made of all metal material, with a 1U metal panel equipped with a dual channel receiver and an LCD display screen. It displays the working channel, working frequency, and 6-level audio level separately. Fully and quickly understand all the action information of the receiver. Operated through an electronic keypad control panel. The all aluminum alloy knob looks more professional and high-end. The host provides four balanced audio output sockets and mixed unbalanced output, fully adapting to various connection requirements. The conference seat adopts an independent exterior design, with high fidelity metal pickup heads and a 3.5-inch high-resolution large screen display, providing a clear view of the working parameters. |
