Infrared frequency of multi-channel wireless meeting microphone. With less noise interference of UHF frequency band PLL phase locking technology. CPU control by microcomputer. All metal material standard chassis, metal panel configuration respectively each channel receiver, LCD screen assembly, using electronic operation button control panel. Host respectively provide balanced audio output socket, every road and mixed unbalanced output, comprehensive to meet the needs of all kinds of connections. Meeting with independent design, high fidelity metal cartridge, 3.5 -inch LCD screen display, working parameters. For senior meeting engineering installation use of first choice.
