DMPS-300-C-AEC provides all-in-one digital AV presentation solution for video conference rooms




Rockleigh, NJ, March 4, 2013 – Crestron today began shipping the DigitalMedia Presentation System 300 with Acoustic Echo Cancellation, the newest addition to its category leading family of all-in-one digital presentation solutions. The DMPS-300-C-AEC features full-bandwidth acoustic echo cancellation on each of its six mic inputs to filter out disruptive echoes from voice communications during teleconferencing calls. DMPS-300-C-AEC integrates directly with up to two audio or video codecs providing a total video conferencing system solution.




“The addition of Acoustic Echo Cancellation to the DMPS makes integration of videoconferencing systems even easier by providing native control of all signal routing and audio processing functions,” said Fred Bargetzi, Crestron VP of Technology. “This eliminates complex interconnections and programming of third party DSP's while providing clean, high quality audio for teleconferencing applications.” DigitalMedia Presentation Systems (DMPS) provide everything needed to deliver the highest performing HD presentation experience available. DMPS efficiently integrates several components into a single rackmountable package, including a control processor, multimedia matrix switcher, mic mixer, audio DSP, amplifier, and now AEC, with DigitalMedia technology to offer a complete digital AV presentation solution.




Built-in acoustic echo cancellation for productive video conferencing
High-performance adaptive acoustic echo cancellation on each mic input enables DMPS-300-C-AEC to connect directly to audio and video codecs to provide a complete teleconferencing system solution for the boardroom or conference room. Its low-latency, full-bandwidth performance provides highly effective echo cancellation with natural sound quality ensuring that conference participants on the far end of the call can hear voices with clarity and understand the conversation without effort. AEC is employed independently per microphone, with a fast convergence rate of 80 dB per second and tail lengths up to 200 ms, to handle any typical small to medium sized room with ease.




Expanded signal routing and audio processing in the DMPS-300-C-AEC allows one or two codecs to be connected to any of the seven source inputs, and either (or both) of the aux outputs. Dual codec support allows both codecs to be used simultaneously, even allowing the signal from one codec to be fed to the other for a fully inclusive teleconferencing experience. Local presentation sourced can be mixed with the microphones and routed to the codecs, allowing far end participants to experience the full presentation without any distracting echo.
