Equipped with Multi-beam Tracking—outstanding beamforming technology for safely capturing each speaker’s voice
RM-CG is a ceiling array microphone equipped with Multi-beam Tracking capable of tracking the simultaneous speech of multiple speakers. Since these beams detect and track the direction of the sound source simply by the speaker speaking, there is no need to adjust the position or range of sound collection in advance.

Users can now pre-set RM-CG's beam-tracking zones using a color-coded system in the Web UI.
- Green represents the overall pick-up coverage of the microphone.
- Blue delineates "focus areas" for more localized sound pick up (up to 2 areas)
- Red creates an "exclusion area", cancelling audio pick-up where specified (up to 2 areas)

The ADECIA ceiling array microphone provides accurate voice tracking. When this information is sent to a compatible camera system, this allows the meeting to follow the conversation – in real-time.
Let us show you how Voice Tracking and Camera Tracking can work seamlessly together.
Achieving clear audio quality through full use of various voice processing technologies
Achieving clear audio quality through full use of various voice processing technologies
As well as being equipped with all kinds of signal processing technologies such as Adaptive Echo Canceller, Noise Reduction, Dereverberation, Automatic Gain Control, and Auto Mixer, when combined with Yamaha's original HVAD (Human Voice Activity Detection) technology, this ceiling array microphone offer clear, high-quality voice reproduction.

Outstanding beamforming technology
Beamforming is a technology by which a directivity response pattern is formed using multiple microphones. The RM-CG can form up to four beams simultaneously. Narrowing the directivity of each beam and centering the beam on each speaker’s mouth enables this system to pick up sound while avoiding the negative impact of reverberation or ambient noise. Moreover, tracking with four beams offers the convenience of not having to set the sound collection range, and it prevents clipping of sound when a person begins to speak.
Adaptive Echo Canceller for Multi-beam Tracking
The Echo Canceller estimates the overall sound (including reflected sound) transmitted between speaker and microphone and reduces it (including reflected sound), thus preventing the voice from echoing back to the speaker. When the overall sound transmission is estimated perfectly, echo will not be generated. However, if the transmitted sound changes rapidly, the system will not adapt quickly enough and the likelihood of echo will increase. As mentioned above, the directions of the Multi-beam Tracking are constantly changing, but Yamaha's Echo Canceller uses an algorithm capable of responding quickly to any changes. As a result, high echo cancellation performance is achieved despite the use of Multi-beam Tracking.
Noise Reduction greatly reduces ambient and background noise
Noise Reduction used in teleconferencing systems estimates the noise contained in a signal from the signal itself and attenuates its components. It enables clear sound collection by detecting steady noise and attenuating only those components.
Dereverberation provides high-quality sound even in reverberant spaces
The RM-CG analyzes the components of picked-up sound in real time, then estimates and removes any unpleasant reverberation components in the sound based on an acoustic model, enhancing the clarity of the picked-up sound.
Automatic Gain Control delivers clear, pleasant conversation to the other parties
The RM-CG reduces the fluctuation in voice levels sent to other parties by automatically adjusting the gain depending on the levels of various voices picked up. In addition, HVAD (Human Voice Activity Detection) works to adjust the voice level only. In this way, HVAD prevents unpleasant sounds from being generated without unnecessarily raising the level of unwanted sound.
Automatic mixing using unique algorithms
General gain-sharing automatic mixing is often used when a microphone is mounted close to the speaker. When applied to the RM-CG, it tends to mix the four beams in a similar way. For this reason, the RM-CG uses automatic mixing optimized for the installation conditions, which demonstrates strong performance even in environments such as ceiling installations or rooms with a lot of reverberation.
Standard support for Dante network audio, enabling Dante audio/control signals and PoE power supply with a single network cable
Standard support for Dante network audio, enabling Dante audio/control signals and PoE power supply with a single network cable
Compatible with the Dante audio network standard, enabling audio/control signals to be transmitted via a single network cable. Since the power supply is PoE-driven, not only the Dante audio signal and control signal but also the power supply can be supplied from the network switch via the same cable.

In medium-sized conference rooms accommodating about 10 to 20 people, coverage can be expanded by connecting four Ceiling Array Microphones.
3 mounting methods for a variety of ceiling environments
With the increasing number of conference rooms and multipurpose rooms that emphasize design as well as function, ceiling array microphones need to adapt to all kinds of installation environments. Choose your installation method, including ceiling mounting using the RM-CG’s standard metal fittings as well as installation using VESA mounting metal fittings for ceiling suspension or hanging with wires.
