The Quattro2 is the largest of our conferencing speakerphones. Its unique audio capabilities and small yet sophisticated design make it an ideal solution for both medium and large conference room settings.

As a successor to our popular Quattro line, the second generation “Quattro2” comes with many new and exciting features and upgrades.

The Quattro2 incorporates the latest in digital signal processing and technology including 4 microphones, 4 speakers, 5 echo cancelers, proprietary Beam Forming Array algorithms, Voice Activity Detectors, De-reverb, Steady State Noise Attenuators, and Dynamic Signal Compression, to name a few.

The hardware and software design of the Quattro2 provide it with an extended rage of audio pickup and broadcasting. This allows the Quattro2 speakerphone to cover larger spaces without the use of satellite microphones or speakers.

Although technologically advanced, the Quattro2 remains a simple and user friendly product. Maintaining our plug-and-play philosophy, the Quattro2 does not require expert knowledge in audio setup or any additional installations such as drivers.

Like all of our products, we put a lot of effort into the design of the Quattro2 to give it a sleek and compact look while maximizing its performance.

The Quattro2 also offers functional daisy chaining capabilities. This unique ability to daisy chain an unlimited number of units assures that no room or hall is too large for the Quattro2. Daisy chained units not only act as active microphones, but also speakers, delivering the full conferencing experience to all participants, regardless of the venue.

All Quattro2s come standard with a USB interface, connecting the devices with a computer. This connection allows the user to use the Quattro2 for recording and VoIP conferencing. The USB connection also provides the device with its only needed source of power. The most basic version of the Quattro2 is the MT-301, equipped only with this USB interface, though the Quattro2 product line offers a range of additional interfaces including telephone, digital phone, and even Bluetooth interfaces. Please refer to the list of Quattro2 products below for more information about the many products available in this line.
