Audix M3DK — Dante/AES67 Ceiling Microphone and Interface Kit
M3DK Overview
The Audix M3DK is a complete ceiling microphone system that combines the Audix M3 tri-element hanging microphone with the Audix DN43 Dante/AES67 microphone interface, delivering a network-ready audio solution deployable over standard Ethernet infrastructure. The M3’s three phase-coherent hypercardioid capsules are frequency and pattern-optimized for voice intelligibility and rejection of extraneous noise, making this kit well-suited for conference rooms, houses of worship, lecture halls, and boardrooms. The DN43 interface provides 24-bit, 48kHz high-fidelity audio with independently controlled preamp gain and selectable filtering per channel. This kit is designed for AV integrators and system designers who require a clean, low-profile installation with professional Dante/AES67 network audio performance.
The M3DK simplifies deployment by routing audio and power over a single Ethernet cable, with the DN43 operating on PoE from any IEEE 802.3af compliant switch, eliminating the need for dedicated power supplies or analog snake runs.
Key Features
- Tri-Element Hypercardioid Capsule Array — Three phase-coherent hypercardioid capsules provide even sound dispersion with undetectable phase artifacts, optimized for voice clarity in reverberant environments
- Dante/AES67 Network Audio — The DN43 interface streams 24-bit, 48kHz audio over standard Ethernet, fully compatible with Dante Domain Manager (DDM)
- Dedicated M3 Microphone Port — One port on the DN43 is engineered exclusively for the Audix M3 tri-element microphone, ensuring proper signal handling and power delivery
- Single-Element Microphone Port — A second port supports Audix RJ45-equipped single-element microphones, adding system flexibility
- Independently Controlled Preamp Gain and Filtering — Each channel features selectable preamp gain plus low-pass and high-pass filters for tailored signal conditioning
- Balanced Audio Inputs with RFI Filtering — Balanced inputs with integrated RFI filtering protect signal integrity in electrically noisy environments
- PoE Operation — Operates on Power over Ethernet from any IEEE 802.3af compliant device, simplifying infrastructure requirements
