Relacart ACM-582 - ceiling microphone array Dante/AES67 with AI, AEC, and PoE power

Clear, intelligible voice from the entire room, without microphones on the table and without cables underfoot. The Relacart ACM-582 is a ceiling microphone array that combines AI technology with advanced acoustic design. Five MEMS arrays automatically cover an area of up to 7.6x7.6m, ensuring that every spoken word is captured accurately and clearly, regardless of where the speaker is seated. Built-in signal processing, including acoustic echo cancellation (AEC), AI-based noise reduction, and automatic gain control (AGC), ensures that the sound reaches the video conferencing or sound reinforcement system ready for use. This solution is for AV integrators equipping conference rooms, lecture halls, classrooms, and auditoriums.

The ACM-582 transmits the signal digitally over a Dante and AES67 network and is powered via PoE/PoE+, so only one Cat5e or better cable with an RJ45 connector is needed for installation. The power consumption is a maximum of 3W. The UL2043 certification allows installation in ventilation spaces above a suspended ceiling, and the IP5X dust protection safeguards the electronics in challenging installation conditions.
