ACT-808 Gooseneck Conference Microphone product image

Product Overview

The Harmonai ACT-808 Gooseneck Conference Microphone is a professional UHF wireless conference microphone system designed for demanding meeting environments. It features PLL frequency synthesis technology, a supercardioid condenser capsule, and a 40 cm gooseneck pickup stem for accurate, clear voice capture. The main unit supports 200 auto-switching channels, allows up to 5 systems to operate simultaneously, and achieves an operating range of up to 150 meters — meeting diverse needs from small-to-medium meeting rooms to large auditoriums.

The system employs a dual anti-interference solution: digital pilot tone and noise-lock squelch control, effectively shielding against mobile phone electromagnetic interference to ensure stable, clean audio throughout meetings. The main unit offers 8 XLR outputs and 1 1/4-inch output, and features standard rack-mount design (88.8 mm H × 483 mm W), enabling seamless integration into professional sound reinforcement systems.
