SR-CM02
Cascading omnidirectional digital array microphone — even voice pickup across large conference rooms.
SR-CM02 is a cascading digital array microphone built for large and medium-sized conference rooms. A six-element omnidirectional array delivers up to 3 metres of voice pickup with minimal configuration, and up to six units can be daisy-chained over a single PoE run for even coverage across the room. Blind beamforming automatically tracks and aligns to the active speaker, while an onboard DSP applies echo cancellation, noise suppression and automatic gain so conversations stay clear even in noisy spaces.

Features
01
Digital array microphone
High-SNR ring microphone array design gives clear pickup from a distance, letting speakers move freely around the room.
02
Blind beamforming
Automatic alignment to the active speaker with precise positioning and adaptive sound-field response for better anti-interference.
03
Smart audio algorithms
Onboard DSP with voice tracking, noise reduction, echo cancellation, automatic gain and de-reverberation for full-duplex dual talk.
04
PoE cascading
Cascade up to 6 units over standard PoE cable for distributed, even sound pickup across large and medium-sized rooms.
