Ceiling Array Microphone RM-CG
Architectural and Engineering Specifications
The solution shall be a beam-forming ceiling microphone. The ceiling microphone system shall be Dante enabled and PoE powered, requiring
only one CAT5e or CAT6 cable for both power and data/audio transmission. The ceiling microphone shall deploy dynamic beam-forming
technology. It shall support multi-beams to be able to capture several areas of the room simultaneously. The microphone beams shall be
following active speakers when moving in the room. When a new person starts speaking either a pre-existing beam shall capture that person
immediately, or a new beam shall form within milliseconds on that location. The ceiling microphone shall offer three options for installation. These
options shall include methods to mount it flush below a ceiling tile, to mount it hanging from a ceiling using wires, and to mount it using a VESA
mount. The ceiling microphone shall include audio post-processing. This shall include Adaptive Acoustic Echo Cancellation, Noise Reduction,
Human Voice Activity Detection, Automatic Gain Control, Automatic mixing of audio signals, dereverberation, and others. The microphone shall
offer different kinds of mixing technology, including “matrix mixing” and “gain-share mixing”. The ceiling microphone shall provide an audio
signal that was only post-processed using linear algorithms allowing for technology like speech recognition to use the signal without loss of
performance. The product shall provide connectivity for third party control systems, allowing to manage system, microphone, and audio behavior
from the room control system. The Yamaha RM-CG is specified.
