Audix M3GDK Dante/AES67 Microphone Interface Kit

The Audix M3GDK is a comprehensive microphone and interface kit designed to seamlessly integrate into Dante and AES67 audio-over-IP networks. This system combines the Audix M3 tri-element hanging ceiling microphone with the DN43 Dante/AES67 microphone interface, offering a streamlined solution for high-quality audio capture in networked environments. Ideal for applications such as video conferencing, distance learning, courtroom audio, and ambient room monitoring, the M3GDK ensures clear and intelligible sound reproduction.

Featuring a tri-element design, the M3 microphone utilizes three phase-coherent hypercardioid capsules, delivering a tailored frequency response optimized for speech clarity and effective rejection of ambient noise. The accompanying DN43 interface supports 24-bit, 48 kHz audio resolution and offers two microphone ports: one dedicated to the M3 microphone and another for single-element microphones with RJ45 connectors. The interface also provides selectable pre-amp gain, low- and high-pass filters, and supports Power over Ethernet (PoE) for simplified installation.
