Phoenix Audio Quattro3 MT305 HD VoIP Conference Phone 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.

All Quattro 3's use the same chassis and internal microphone and speaker arrays. The Phoenix Audio Quattro 3 offers variable models differing only in what connection interface exists on the unit. The Quattro 3 USB MT301 has only a USB connection. All connection interfaces are interchangeable, so if you want to use your Quattro 3 in a different situation from what you initially intended, you can buy only a new interface and connect it to your Quattro 3. The Quattro 3 MT-305 interface has a USB connection, a 3.5mm connection, power in/out port for daisy chaining, and an RJ45 Ethernet port so it can be used as a SIP enabled VoIP conference phone.
