Reach Array 7 Interact ACM702-Audio

Product introduction

Reach Array 7 Interact ACM702 is an education- and conference-grade ceiling array microphone built for clear, natural speech capture at a distance. Six high-SNR microphones in a circular array deliver true 360° omnidirectional pickup, while blind beamforming automatically locks onto the active speaker and adapts to the acoustics of the room.

Its on-board processor runs voice tracking, noise suppression, echo cancellation, automatic gain control and de-reverberation at ultra-low latency — keeping speech intelligible in noisy, reverberant spaces, with double-talk never suppressed.

Powered and cascaded over a single PoE network cable, up to six ACM702 units work as one distributed pickup system for medium and large rooms, while standard USB and 3.5 mm Aux interfaces keep the microphone plug-and-play in digital and analog audio chains.

Product views

The ACM702 is a slim ceiling plate: a 360° microphone array face on the front, and a mounting plate that carries the cascade and audio ports on the rear.

Front view — 360° microphone array face.

Rear view — mounting plate and connection ports.

System connection

Single-unit mode: one ACM702 is powered over PoE and delivers digital audio through USB or analog audio through the 3.5 mm Aux ports to a host, recorder, DSP or loudspeaker. Cascade mode: set one unit as master and the others as slaves, then chain them with PoE network cables through the UP and DOWN ports — one PoE run carries both power and audio, up to six microphones for even coverage of medium and large rooms.

System connection — single-unit mode and PoE cascade mode (up to six microphones on one PoE run).

Key features

1Six-microphone circular array

• A high signal-to-noise ring array captures speech clearly at distance and lets speakers move freely around the room.

2Blind beamforming

• Precise, automatic alignment to the active speaker with adaptive voice enhancement and strong resistance to interference.

3Smart audio algorithms

• Ultra-low-latency DSP with voice tracking, noise suppression, echo cancellation, automatic gain control and de-reverberation — double-talk without suppression.
• Plug-and-play out of the box, with an open EQ interface for advanced tuning.

4PoE cascading

• Flexible master / slave configuration over one PoE network cable — up to six microphones for distributed pickup and even coverage of medium and large rooms.

5Standard interfaces, flexible mounting

• USB and 3.5 mm Aux audio I/O for digital and analog audio; desktop, ceiling or wall installation for fast deployment and low maintenance cost.
