The MT-301 USB Quattro2 Conferencing Speakerphone from Phoenix Audio offers high-quality audio and advanced features in a stylish and user-friendly design. The compact housing has 4 internal mics and speakers to provide an extended range of audio pickup and broadcasting. The USB connection provides the unit with power, as well as plug-and-play use with Macs and PCs with no drivers required. This allows you to use the speakerphone for conducting and recording VoIP calls and meetings, as well as playing back audio through your computer's media player. A 3.5mm speaker jack allows you to connect your own external speakers if desired.
The Quattro2 offers advanced digital signal processing to ensure the highest possible audio quality on both sides of a conversation. There are 5 echo cancelers, proprietary Beam Forming Array Algorithms, Voice Activity Detectors, De-reverb, Steady State Noise Attenuators, and Dynamic Signal Compression, just to name a few. There are also free downloadable software programs (Windows only) so you can expand the functionality of the speakerphone.
The Quattro2 has a multi-pin jack that allows unlimited daisy-chaining, ensuring that no space is too large. The MT-301 acts as the master unit that is connected to your computer, and an unlimited number of MT-304 daisy-chain units (sold separately) can be added. The additional units deliver the full conferencing experience by acting as mics and speakers, unlike satellite mics found in other systems.
