ACM-335

Relacart ACM-335 - Ceiling Microphone Array

The Relacart ACM-335 is a professional ceiling microphone array designed for AV integrators working in conference rooms, classrooms, and educational spaces. Combining advanced acoustic engineering with AI-powered signal processing, this microphone ensures crystal-clear voice capture and intelligent noise management. With 5 MEMS microphones and Dante/AES67 support, the ACM-335 delivers 360° voice pickup while minimizing echo and background noise, even in acoustically challenging environments.

Functional Features

• AI-based de-reverberation using Deep Neural Networks (DNN) - improves Direct-to-Reverberant Ratio (DRR)
• Dynamic feedback suppression - automatic elimination of narrowband feedback
