Radius AEC is an open architecture audio DSP conferencing solution with the optimum number of audio inputs and outputs for small to medium sized rooms. For large conference venues, multiple units are networked using the Dante protocol. Radius AEC adapts to specific installation requirements with an expansion card slot for adding a SymNet Modular I/O card, such as the 2 Line Analog Telephone Interface. Support for an array of user control options makes it easy for contractors to satisfy their customers. Low latency and lightning fast AEC convergence deliver superior intelligibility for more effective communications.
