ACT-720 True Diversity Wireless Microphone System product image

Product Overview

The MXH ACT-720 is a professional true diversity wireless microphone system, built with advanced PLL phase-locked loop frequency synthesis technology and microcomputer CPU control, supporting 700-meter ultra-long-range signal transmission (in open, unobstructed environments). The system offers 2×100 channel switching, infrared auto-synchronization, and interchangeable use of microphones A and B—ideal for professional live performances, conference speaking, and educational training.

The receiver employs a true diversity dual-reception circuit paired with digital pilot tone technology to effectively eliminate signal dropouts and dead zones. Dual noise squelch protection—comprising noise-lock squelch and tone-code navigation squelch—ensures clean, stable audio. Audio dynamic expansion and automatic level control circuits deliver natural, transparent sound reproduction.
