Adecia Solution
With new and ever-changing communication requirements, one thing remains the same: the need for high-quality, worry-free audio for collaboration. ADECIA Ceiling Solution, featuring the new Ceiling Array Microphone RM-CG and Conference Processor RM-CR, helps organizations overcome challenges with implementation, configuration and room acoustics by providing all components required for a successful installation - designed to work seamlessly together to reduce set up time, costs and complexities.

RM-CG
The RM-CG dynamic ceiling array microphone features multi-beam tracking technology which focuses on voices. Thanks to the special spiral layout of its microphone elements, the RM-CG provides the narrowest, most precise beam for voice capture, while continuous background noise is eliminated using Yamaha’s advanced noise reduction algorithms and Human Voice Activity Detection (HVAD). Combined with its beam tracking technology, it can clearly pick up individual voices, even when more than one person is speaking. Dante audio and the control and power are supplied through one LAN cable, while three different mounting methods - ceiling, VESA and wire mount - are included to suit any space.

Key Features:

• Standard network audio support for “Dante”
• “Dynamic Voice Tracking” that scans for human voice
• Four “Auto Tracking Beams” track simultaneous speech allowing for lively conversations
• Utilizes innovative Yamaha technologies like Adaptive Echo Canceller, Automatic Gain Control, Noise Reduction, and Dereverberation
• Automatic detection and configuration with Remote Conference Processor RM-CR
• Utilizes one PoE+ network cable connection avoiding troublesome wiring and enabling audio control via Dante
• Supports 3 types of mounting methods for use with a variety of ceiling conditions

Multi-beam Tracking
Multi-beam tracking is a signal processing technology that can track multiple speakers by combining the use of Beamforming technology, which forms directivity with multiple microphone elements to pick up sound, to create multiple beams, and dynamic tracking technology, which allows each beam to cleverly track different speakers' voice when multiple speakers are present.

Adaptive Echo Canceller
While other echo canceller's measure the room and set levels once, Yamaha's adaptive echo cancellation is constantly scanning the environment for changes to deliver an uninterrupted, echo-free audio stream.

Noise Reduction
When constant noise like a projector fan or air conditioner system enters the communication space, Yamaha's Noise Reduction technology removes these components to clearly convey the presenter's audio to the far-end.

Auto Tracking Beamformimg
The four dynamic beams simultaneously track multiple people, allowing for lively conversations. With a narrow directivity of each beam, the system accurately captures speech while suppressing background noise, enabling a highly intelligible voice to the far end.

Auto Gain Control
This sound technology automatically adjusts voice levels to deliver a consistent, optimal volume level to the far-end, no matter if some voices are louder vs. weaker or closer vs. further away from the microphone. This automatic feature enables everyone to hear or be heard at an ideal level.

Dereverberation
Reverberation from an acoustically-poor environment can make it difficult to distinguish a clear voice signal. Dereverberation suppresses these reverb components to deliver a highly-intelligible output.
