Boundary Microphone RM-TT

Architectural and Engineering Speciﬁcations

The solution shall be an intelligent tabletop microphone. The tabletop microphone system shall be Dante enabled and PoE powered, requiring

only one CAT5e or Cat6 cable for both power and data/audio transmission. The tabletop microphones shall support programmability for

several audio pick-up patterns. Audio pick-up patterns shall include omni-directional and a toroid pattern to capture 360 degree around the

microphone with toroid reducing sounds from above the microphone. The microphone shall also allow for cardioid, super cardioid, and hyper

cardioid pick-up pattern. When selecting any of the cardioid pick-up patterns, up to four independent directions (“channels”) shall be available

to deﬁne per microphone and all four will be active. A predeﬁned bi-directional cardioid pick-up pattern with two lobes opposite to each other

shall be available, with free selection of the direction of that pattern. When selecting several active channels, different mixing options shall be

offered, including gain-sharing options and all-mix. The tabletop solution shall also offer an Active Voice Tracking setting in which the microphone

elements that provide the best audio capture are automatically selected and mixed into the audio output of the microphone. The 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. An installation mechanism shall be provided to install

microphones in a ﬁxed location on surfaces like tables. Each tabletop 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 microphone and audio behavior from the room control system. The Yamaha

RM-TT is speciﬁed.
