Architectural and Engineering Specifications
The solution shall be a complete audio solution for conference rooms and conference spaces. All components in the solution shall be Dante
enabled and PoE or PoE+ powered, requiring only one CAT5e or CAT6 cable for both power and data/audio transmission to the devices. The
solution shall include one or two ceiling microphones, two wall speakers, an audio processor, and a network switch all from one manufacturer.
The ceiling microphone shall deploy dynamic beamforming 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 ush 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 Echo Cancellation, Noise Reduction, Human Voice Activity Detection, Automatic Gain Control, Automatic mixing of
audio signals, 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 postprocessed using linear algorithms allowing for technology like speech
recognition to use the signal without loss of performance. The wall speakers shall be line-array speakers with 16 speaker elements each. Two
speakers shall be included in the solution. The line array wall speakers shall create a directionality to the audio signal, resulting in reduced signal
loss over distance. The line array wall speakers shall be specically designed for communication and conferencing applications, with emphasis
on the typical frequency spectrum of human voices. The room audio processor shall support a means to detect the separate solution devices
like ceiling microphone and wall speakers and auto-congure the audio ow between these devices. As part of that process it shall congure the
devices to communicate correctly with each other. It also shall provide a mode to automatically measure the acoustic in the room and tune the
devices to the specic room acoustic. The room audio processor shall integrate with standard call managers using SIP telephony. It furthermore
shall support Bluetooth to connect to cell phones. USB audio shall be supported for integration with Unied Communications clients. The room
audio processor shall support analog audio for connections with video appliances / codecs. The room audio processor shall support two analog
microphone inputs for presenters in the room. These inputs shall allow voice lift for audio on these microphones, but at the same time mix the
audio into the outgoing stream on USB, BT, analog audio, and SIP. Feed-back suppression shall be supported on these microphone inputs.
A network connection into the room audio processor shall allow for remote management of the overall solution from a corporate network. The
network switch shall be approved and pre-congured to be used in Dante networks. It shall support PoE+ support on eight connections, up to
240 Watts. The solution shall provide connectivity for third party control systems, allowing to manage system, microphone, and audio behavior
from the room control system. It shall be remotely accessible for monitoring and managing. The solution shall be able to send proactive
information on its state and possible problems to a management system. The Yamaha ADECIA ceiling solution is specied.
