Phoenix Audio MT304 Quattro3 USB & Power Daisy Chain conference phone connects to any computer as well as have the option to power a Quattro3 daisy chain link via one power source without the need of another interface.  

The Quattro3 is technologically advanced yet simple and user friendly.  It's easy to set up with plug-and-play so you don't have to be an installation expert.  The Quattro3 MT304 conference phone will work with any computer based app thru its USB interface. Its unique audio capabilities and small sophisticated design makes Quattro3 ideal conferencing solution for both medium and large room settings.  The hardware and software design of the Quattro3 provides an extended range of audio pick-up and broadcasting which allows Quattro3 to cover even larger spaces without the use of satellite microphone or speakers. 

The Phoenix Audio Quattro3 also offers daisy chaining capabilities - the built-in daisy chain interface has 2 connectors for link-up and link-down.  Quattro3's ability to daisy chain an unlimited number of units assures that no room or hall will be too large for the Quattro3.  Daisy chained units not only act as an active microphone, but also speakers, delivering the full conferencing experience to all participants, whatever the venue.  Daisy chain up to 8 consecutive units before requiring another power source, and up to 15 with with a Ethernet cable.

Greatly improved over its predecessor, the Quattro3 has a new process that's twice as powerful.  The improved design relocated all Quattro3 connectors conveniently under the unit to allow discrete cable connections.  It was a much improved and patented Daisy Chain algorithm along with new Daisy Chain Ethernet cable to improve reliability over the proprietary cables.  Q3 is also the first truely modular Quattro with user interchangeable interface cards and new simplified method to replace them via 2 simple screws.  The new interface also include a fully independent IP phone, and a much anticipated built-in dialer with backlit display for both PSTN and IP interface models.

Love the daisy chain capabilities , 4/19/12
By Wes Taylor
This is truly a versatile conference system. Each unit is great by itself but when you need to cover a larger space you can more units to the conversation. That is a great feature to have. Also, you can use 1 power source now instead of having to power each conference unit. Thanks to Gerald (I think that was his name) at The Telecom Spot for explaining how it all works.

daisy chaining capabilities
easy to setup

none that I can think of right now
