Ceiling-mount array microphone
CR-LM043
The CR-LM043 is a ceiling-mounted array microphone. Equipped with proprietary advanced AI algorithms, it achieves precise pickup within a dynamic adjustable angle range, creating an effective "sound pickup zone" that isolates speech in noisy environments. It integrates powerful features including noise reduction, echo cancellation, dereverberation, and automatic gain control. Designed specifically for top-down installation in meeting spaces, it requires only a single unit deployment and one cable connection to quickly capture cleaner, clearer audio.
The CR-LM043 supports connecting up to 2 additional ceiling or wall‑mounted speakers for audio amplification, and can be daisy‑chained with up to 6 units of the same model to accommodate extra‑large conference rooms.

The CR-LM043 ceiling-mount array microphone is an AI-powered audio solution designed for modern conference rooms, boardrooms, and hybrid meeting spaces. Featuring a large 43-capsule microphone array and intelligent audio processing, it captures speech within an adjustable pickup zone while reducing unwanted background noise, echo, and room reverberation.
Designed for top-down installation, this ceiling-mounted microphone helps keep meeting tables and work surfaces free from desktop microphone units. With PoE+ connectivity, USB, audio I/O, and RS-232 interfaces, the CR-LM043 can be integrated into professional video conferencing systems and conference room AV environments.
The microphone supports noise reduction, dereverberation, echo cancellation, feedback elimination, automatic gain control, and zone pickup/audio wall functions. It can also connect with up to two additional ceiling- or wall-mounted speakers for audio amplification and support daisy-chaining of up to six CR-LM043 units for larger conference environments.
For complete AI video conferencing deployments, the CR-LM043 can be configured with other CREATOR products, including conference controllers and PTZ cameras, to build an integrated meeting room audio and video solution.
Key Benefits
AI-Enhanced Speech Pickup
The 43-capsule microphone array works with integrated AI audio algorithms to focus on speech within the selected pickup area. Adjustable pickup zones help the system adapt to different meeting room layouts and participant positions.
Clearer Conference Room Audio
The CR-LM043 combines noise reduction, echo cancellation, dereverberation, and feedback elimination to improve speech clarity in meeting environments where ambient noise and room acoustics can affect communication.
Flexible Ceiling Installation
As a ceiling microphone for conference rooms, the CR-LM043 supports hanging, ceiling-mounted, and suspended installation methods. Its top-down design provides an alternative to placing individual microphones directly on the meeting table.
Scalable Large-Room Deployment
One CR-LM043 can be expanded with additional units, with up to six units of the same model supported in a daisy-chain configuration. This allows the microphone system to scale according to the size and layout of the conference space.
Features
Large 43-capsule microphone array for broad speech pickup coverage.
AI audio algorithms with noise reduction, dereverberation, and echo cancellation.
Adjustable zone pickup and audio wall functions for more controlled speech capture.
Automatic gain control and feedback elimination for stable conference room audio.
Supports mute/unmute, zone switching, volume adjustment, and conference/amplification mode switching through remote control functions.
Supports connection to up to two additional ceiling- or wall-mounted speakers for audio amplification.
Supports daisy-chaining of up to six CR-LM043 units for large conference rooms.
Flexible connectivity with PoE+ Gigabit Ethernet, USB, audio, Phoenix terminal, and RS-232 interfaces.
Optional Dante support for compatible professional AV configurations.
Suitable for integration with video conferencing systems, conference controllers, PTZ cameras, and other meeting room equipment.
Why Use a Ceiling Array Microphone?
Traditional desktop microphones require equipment to be distributed across the meeting table and may become inconvenient as room size or participant numbers increase. A ceiling array microphone provides a different deployment approach by positioning the microphone above the meeting area and using an array-based pickup system to capture speech from participants below.
For professional conference rooms, this approach can help simplify tabletop layouts while providing a scalable audio architecture. The CR-LM043 is particularly suited to installations where clean table surfaces, centralized AV deployment, and expandable microphone coverage are important considerations.

Applications
Conference Rooms
The CR-LM043 is designed for professional conference room audio applications, providing ceiling-mounted speech pickup and AI-based audio processing for meetings and discussions.
Executive Boardrooms
The ceiling installation keeps the tabletop area less cluttered while providing an integrated audio solution for executive meetings, presentations, and remote collaboration.
Hybrid Meeting Spaces
When combined with cameras, conference controllers, and other AV equipment, the CR-LM043 can form part of an AI video conferencing system designed for communication between in-room and remote participants.
Large Conference Rooms
For larger meeting environments, multiple CR-LM043 units can be daisy-chained to expand the microphone deployment according to the room layout and required coverage.
Training and Presentation Rooms
The microphone can support speech pickup in meeting and presentation environments where participants or presenters need to communicate while keeping desktop equipment to a minimum.
System Integration
The CR-LM043 can be used as the audio pickup component within CREATOR's AI Enterprise Video Conference System. Depending on room requirements, it can be configured alongside:
- CR-VB01C All-in-one Android conference controller for integrated conference control, audio, and video functions.
- CR-V1015P20A Dual-lens PTZ camera for AI-powered video tracking and long-distance video capture.
- Additional ceiling- or wall-mounted speakers for conference room audio amplification.
This modular approach allows the audio system to be configured according to room size, meeting format, and AV equipment requirements.
