The Duet is our desktop speakerphone product line. Its built-in microphone and speaker, paired with advanced echo cancellation and noise suppression technologies, make it a very powerful yet portable small to midsized conference room solution. Its light weight and discrete design make it ideal for hands-free desktop conferencing, while its powerful pickup and speaker volume allow it to maintain a large range of coverage. The Duet provides a quality speakerphone solution for desktop users while maintaining a user friendly, plug-and-play, mentality. It does not require expert knowledge or additional driver installations in order to use or install. The Duet Executive also comes with the ability to be daisy chained. This unlimited chaining ability accommodates larger rooms, thus broadening the Duet Executive’s range of uses from a desktop solution to a medium conference room solution. By providing this ability, two or more Duet Executives can be taken from desktops in an office and combined in a larger room to provide a single yet larger conferencing solution. All Duets come standard with a USB interface, connecting the devices with a computer. This connection allows the user to use the Duet for recording and VoIP conferencing. The USB connection also provides the device with its only needed source of power
