Canadian Space Agency Specify Sonifex Telephone Hybrid
9th November 2010
The Canadian Space Agency based in Quebec have recently bought a Sonifex DHY-03T Digital Telephone Hybrid to use in a large, live, teleconference project. The specification required that the hybrid should have built in echo cancellation and the Sonifex hybrid was the perfect product for them. The unit has internal memory allowing echo cancellation to 127msec and distortion of other mixed signals is greatly improved. This improves the hybrid’s ability to accept calls from people on mobile phones, or where there are other delays, for example, on satellite and conference calls. The DHY-03 can recall signals from its memory buffer and allow for these delays without impairing performance.
Gregory Viger, Audio-Visual & Technical Communications Specialist at the Canadian Space Agency, was responsible for specifying and installing the product. He said: “All I can say is that the sound quality is amazing in a live event type of environment. It’s a great product!”
The DHY-03 hybrid has a number of features which combine to offer probably the best rejection ratio of any hybrid at between 75 and 80dB. International settings and universal line compatibility allow a good technical impedance match with the line, no matter where it is in the world. Other features include input and output gain adjustment, input and output metering, conferencing, local/remote line hold switching, integrated auto-answer, automatic call disconnection, auto-ducking, DTMF tone recognition, a balanced mic/line input, a balanced line output and serial control, with free of charge control software available on the Sonifex website.
