UX3220-4 (yituo 4)

This series of products for infrared frequency of four-channel wireless meeting microphone, with less noise interference of UHF frequency PLL phase locking technology, microcomputer CPU control, noise interference. 396 channels to choose from, regardless of A, B, C, D, it is more convenient to use. All metal material standard chassis, metal panel configuration per channel receiver respectively, with LED digital display, each channel volume by encoder, avoid long time use to produce noise and so on. Host respectively provide balanced audio output socket, every road and mixed unbalanced output, comprehensive to meet the needs of all kinds of connections. Microphone configuration LED lattice screen, display the working state of the receiver, an unobstructed, high-grade beautiful generous, adopt imported from silent mute switch and high-fidelity imported condenser cartridge, make good noise reduction. For senior meeting engineering installation use of first choice.
