A compact but advanced modular teleconferencing system.

The base station offers mini-jack audio connections to facilitate videoconferencing via computer or third-party video system, and the entire system employs RF shielding (known by Revolabs as "RF Armor") to reject interference from all RF devices, mobile phones in particular. During the evaluation time I spent with the system, I never heard any kind of RF interference whatsoever. And as I said, the sound fidelity was very good. The two mics are each intended for slightly different purposes. One is a clip-on mic that is intended to follow along with a meeting leader, particularly if that person is going to move around, perhaps in the process of delivering a PowerPoint presentation. The other mic is intended as a tabletop device, and I put it through its paces by moving it substantial distances from a single attendee and discovered that it still conveyed that person's voice very clearly to the person on the other end.

The Revolabs FLX2 conference phone is a moderately sophisticated modular system that provides truly excellent call fidelity going both ways, and offers some very nice additional capacities, the most impressive of which, in my mind, is Bluetooth functionality. Considering the price tag, I'd strongly recommend taking a look at this system if you need a good solution on a limited budget.
