PHOENIX AUDIO DUET PCS Personal Conferencing USB Speakerphone



Phoenix Audio's Duet is a best-in-class speakerphone for the desktop voip user and road warrior. It is the primary audio interface for the mobile workforce, dependent on voip for communication.

The Duet generates clear communication through proprietary Acoustic Echo Cancellation, Line Echo Cancellation, Noise Suppressiona and equalizer algorithms embedded within the product. The Duet provides 360 degree room coverage so more than one person can participate in an online conference, Headset-Free and Handset-Free. Loudspeaker output (always a problem with laptops) is sufficient for larger offices and even medium sized conference rooms.

The Duet can be utilized in a number of configurations. In its most simple, a USB interface to the PC powers the speakerphone. More sophisticated options include connecting Duet to IP Phones, POTS and even cellphones through available headset connections. Duet connectivity to any of these phones and the PC gives users the advantage of conferencing voip callers together with standard callers. Last, users have the option of connecting their headset to the Duet for private communication, such as required in IP call centers or public spaces.

The Duet enhances the user experience with many PC applications: VOIP, softphone, web conferencing, distant learning, instant messaging, sound recording, telemedicine, etc. Furthermore, the Duet can improve your telephone's or cellphone's speakerphone performance as well.

Lightweight and sleek design, the Duet has redefined the standard in speakerphones for the desktop and revolutionized audio performance for laptops on the road.
