He has been designing audio equipment since the early 1980s. At Prism Sound, he focuses on R&D and production activities but also works on a few design projects now and then. Current interests include audio conversion, audio-test equipment and methods, media-streaming devices, and audio networking. Dennis is vice chairman of the Audio Engineering Society SC-02-01 Standards Committee for audio test and measurement and also works on standards development within the BSi and International Electrotechnical Commission, most recently contributing to IEC 61606-3 test methods for professional digitalaudio equipment and ITU BS.1770 loudness metering. www.edn-europe.com MAY 2012 | www.edn-europe.com EDN EuropE 31 http://www.digikey.com/europe http://www.edn-europe.com/documents/Dennis_table1.doc http://www.bit.ly/w6uBUo http://www.bit.ly/w1S33y http://www.bit.ly/wKIQpU http://www.bit.ly/yJlmqU http://bit.ly/AurkSB http://bit.ly/AurkSB http://bit.ly/xoMAVu http://bit.ly/xoMAVu http://www.bit.ly/wNJAzw http://www.bit.ly/A27aF3 http://bit.ly/x2xDGU http://bit.ly/x2xDGU http://www.bit.ly/wniJs3 http://bit.ly/zU0BZs http://bit.ly/zU0BZs http://www.bit.ly/AckWHL http://www.bit.ly/xgOPWH http://www.bit.ly/zKCKfq http://www.edn-europe.com
