Relacart Ceiling Array Microphones - Comparison of ACM-335 and ACM-582 Models
2025-10-30Relacart offers two advanced ceiling‑mounted array microphones - ACM‑335 and ACM‑582 - designed for professional AV installations in conference rooms, educational facilities and corporate environments. Both models leverage AI‑based audio processing and support Dante and AES67 protocols, delivering high speech intelligibility, effective noise suppression and seamless integration into IP‑based audio systems.
While the two microphones share the same core audio technology and processing capabilities, they differ in physical format and installation flexibility, allowing system designers to select the most appropriate solution for each project.
Relacart ACM-335 - Compact Ceiling Array for Suspended Ceilings
The Relacart ACM‑335 is a compact ceiling array microphone measuring 335 x 335 x 33mm, equipped with five MEMS microphones. It provides coverage of an area up to 7.6 x 7.6 metres, making it suitable for typical meeting rooms, training rooms and smaller collaboration spaces.
The ACM‑335 includes a full set of advanced DSP features, such as:
- AI‑based 360° noise reduction
- intelligent reverberation suppression using DNN technology
- full‑duplex echo cancellation
- dynamic acoustic feedback suppression
- automatic gain control (AGC)
The microphone is powered via PoE / PoE+ and outputs audio over Dante / AES67 (single channel, 48kHz, 24‑bit). Its acoustic performance parameters support stable and predictable operation in professional AV environments. In addition, IP5X and UL2043 certifications allow safe installation in plenum ceiling spaces.
Relacart ACM-582 - Greater Installation Flexibility and Architectural Integration
The Relacart ACM‑582 is a larger variant, measuring 582 x 582 x 52mm, also featuring five MEMS microphones and offering the same 7.6 x 7.6 metre coverage area. In terms of DSP functionality and acoustic performance, it matches the ACM‑335, providing identical AI‑driven processing and network audio capabilities.
The key distinction of the ACM‑582 lies in its installation versatility. The microphone can be mounted:
- flush‑mounted into the ceiling,
- surface‑mounted,
- suspended using cable or pipe mounting systems.
This flexibility makes the ACM‑582 particularly well suited to architecturally sensitive or representative spaces where visual integration is a priority. Installation is simplified through the use of a single Cat5e (or higher) cable, carrying both power (PoE+) and audio data.
The ACM‑582 integrates fully with Dante Controller and Relacart TDM software, enabling efficient configuration, commissioning and ongoing system management.
Summary - Which Model Is Right for Your Project?
Both Relacart ACM‑335 and ACM‑582 deliver advanced AI‑based audio processing, high speech clarity and full compatibility with modern Dante/AES67 audio networks.
- ACM‑335 is well suited to projects where a compact form factor and standard suspended‑ceiling installation are required.
- ACM‑582 is the preferred choice for applications demanding greater mounting flexibility and enhanced architectural integration, particularly in premium or representative spaces.
In both cases, integrators benefit from reliable network audio transmission, effective noise and echo control, and seamless integration into professional Audio‑over‑IP systems, making either model a strong foundation for modern conference and collaboration environments.
