The Vortex® EF2280 is a multichannel acoustic echo and noise canceller with integral automatic microphone / matrix mixer. It is a complete all-in-one solution for audio and video conferencing, distance learning, courtrooms, and more. The Vortex has been shipping since February 2001.
The Vortex® EF2241 is typically installed in smaller rooms that require audio conferencing, or as a companion to the EF2280 Vortex®. Based on the technology of our popular Vortex audio conferencer, the EF2241 offers 4 mic/line inputs, 4 line inputs, 8 line outputs, an integrated phone add, and a 10-watt power amplifier
The Vortex EF2201 is the next generation of DSP-based conference telephone interfaces. It features a complete digital interface to other Vortex products using a single cable – analog input and output connections are not required.
Polycom's Vortex EF2211 improves the overall audio quality of existing conferencing installations, and can also be used as a standalone system for individual sites. The unit is typically utilized in meeting rooms, along with one or more microphones and an automatic microphone mixer. A telephone interface with ambient noise cancellation can dramatically improve the receive audio quality on phone calls, and the 10-watt power amplifier drives small loudspeakers in the room.
The Vortex EF2210, a stand-alone system for individual sites, is typically installed in meeting rooms along with one or more microphones and an automatic microphone mixer. Because the EF2210 delivers robust acoustic echo and noise cancellation performance, it is often used instead of the video conferencing codec's microphone and acoustic echo canceller. It provides a single microphone or line level input, plus two auxiliary inputs (for external devices such as a VCR).
