& Telephone

The Quattro3 (Q3) USB and Telephone is a high-quality conference speakerphone that will turn any room into a professional conference room. It has an exceptionally large pickup and broadcasting range, yet is small in size and discrete in design. The Quattro3 utilizes multiple microphones, a uniquely designed speaker, and a powerful DSP to achieve commanding performance. The Quattro3 MT305 SIP/IP model connects to any computer via USB and is compatible with most SIP/IP phone service providers. It comes equipped with a built-in keypad and LCD screen.

*Note: If your PBX System does not support PoE, you will need to purchase the 48V Power Supply (MT320) to power the MT305.
