Phoenix Audio Quattro3 PSTN + Dial Pad

Phoenix Audio MT302 Quattro3 (PSTN + Dial Pad) Conference Phone

The Phoenix Audio Quattro 3 is a high quality conference speakerphone that will turn any room into a professionally sounding conference room. The MT302 model with PSTN and Dial Pad features a USB connection as well as an RJ11 telephone Jack for connectivity. It also includes an integrated dial pad, which is unlike its predecessor the Quattro2. It has an exceptionally large pickup and broadcasting range, yet is small in size and discrete in design. The Quattro 3 utilizes 4 microphones, a uniquely designed speaker, and a powerful Digital Sound Processor (DSP) to achieve its fantastic performance.

Phoenix Audio Quattro3 Overview

The new Quattro3 utilizes a single loudspeaker specifically developed and tooled for the Quattro3. This custom made driver delivers even more power and bandwidth than the four speakers used in the Quattro2.

Each and every Quattro3 can be daisy chained to other Quattro3 units with included cat5 cabling up to 15 units. When daisy chaining multiple Quattro3's together, each Quattro 3 can be powered individually with the included power supply. The Q3 also offers the option to power up to eight units through the daisy chain cables using a single 48V international power adapter. In order to use the “Powered Chain” option, each of the Quattro3 units in the chain has to have some type of interface. (All Quattro 3's except the MT301 USB model have an included interface.) The daisy chain utilizes two standard Ethernet connectors, with green and red light indicators. These connectors and the use of standard Ethernet cables guarantee a reliable daisy chain connection.
