Biamp introduces next generation of NEXIA processors

Designed specifically to provide crisp, clear audio in any videoconferencing or teleconferencing application, Biamp ® is introducing its newest line of digital signal processors: The Nexia VC and Nexia TC. The Nexia VC and Nexia TC processors are intuitive, network-ready processors that provide a full range of audio routing and signal processing features, including full wide-band acoustic echo cancellation, in single, economical, easy to install boxes.

The Nexia VC and Nexia TC processors feature Biamp’s 20 Hz to 20 kHz acoustic echo cancellation during multiple participant conversations. Previously available only in the AEC2w add-on cards for Biamp’s AudiaFLEX, this wideband acoustic echo canceling greatly enhances intelligibility and audio performance in conference settings, especially videoconferences. Nexia VC and Nexia TC also feature a network-friendly open architecture design that allows integrators to customize each unit to meet each project’s room-specific criteria. Biamp’s proprietary Nexia software makes Nexia VC and Nexia TC customization easy, allowing integrators to create intuitive custom control programs and choose between Ethernet ports for password-protected access via any networked PC, or serial ports for third party remote controls.

With 10 dedicated mic/line inputs – eight with AEC and two standard – and four mic/line outputs, Nexia VC and Nexia TC units can accommodate an audio system on its own, or can be linked via Ethernet and/or NexLink to create multi-unit systems that can accommodate larger audio networks. Each Nexia processor features an application-specific interface: the Nexia VC with a codec interface and the Nexia TC with a telephone interface on a pair of RJ11 jacks. Both units offer analog inputs and outputs and internal 24-bit A/D and D/A converters operating at a sample rate of 48kHz.

The Nexia VC and Nexia TC are CE marked, UL Listed and covered under Biamp’s five-year warranty.

Helpful Hints

Frequency response
A flat frequency response has been the main goal of microphone companies for the last three or four decades. In the fifties, mics were so bad that console manufacturers began adding equalizers to each input to compensate. This effort has now paid off to the point were most professional microphones are respectably flat, at least for sounds originating in front. The major exceptions are mics with deliberate emphasis at certain frequencies that are useful for some applications. Problems in frequency response are mostly encountered with sounds originating behind the mic.
