Ceiling Array Unit
Microphones — Sound Reinforcement
SR-MC128D
Seamless sound reinforcement ceiling array microphone — one ceiling unit for the whole room.
A 128-element ceiling array microphone built for large-room sound reinforcement, with a sound amplification distance of 4 metres and a pickup distance of 8 metres. An 8-core professional audio processor runs a low-latency ClearVoice AI algorithm, real-time feedback suppression, adaptive sound-field control and dynamic beamforming to deliver clear, high-fidelity vocals whether the room holds 30 people or 800. Built-in cascading and a Dante module let multiple units work together across large auditoriums.

Features
01
Wide sound pickup
A 128-element omnidirectional array delivers a 4m amplification distance and 8m pickup distance, covering any position in the room.
02
Clean, clear sound
Onboard ClearVoice AI deep algorithm accurately recognises speech, removes noise, and enhances speech signals in real time.
03
High flexibility
Supports 33 pickup zones and 17 amplification zones with custom positioning, and cascades to multiple units for larger spaces.
04
Easy to expand and manage
Rich analog and digital (Dante, USB) audio interfaces plus infrared, RS485 and network control for flexible system integration.

Note: the source manual’s feature summary quotes sound feedback gain ≥ 15 dB and 129 microphone elements, which differ from the specification table figures shown here (128 elements, ≥18 dB) — the spec table’s numbers are used above. Applications inferred from described use cases (not an explicit tag list in the source manual). All figures are nominal, per manufacturer data.
