®
Distributed Echo Cancellation
®
—four, eight, or twelve input digital signal
processors (DSPs) improve full-duplex performance and remove echo in the most difficult acoustic
environments.
New PTT (Push-to-Talk) microphone compatibility provides greater design and configuration flexibility.
New EC (Echo Cancellation) Reference Summing uses multiple signals for echo cancellation without
requiring a dedicated output.
Advanced noise cancellation reduces background noise caused by fans, HVAC systems, and other relatively
constant background noise sources.
Four independent signal processing blocks with 15 user-configurable filters (including all pass, low pass,
high pass, low shelving, high shelving, and parametric), delay, and compression. ClearOne
®
’s unparalleled
processing power enables you to use all of these features simultaneously in any combination, allowing you to
deliver optimized audio configurations for every environment and application.
Enhanced expansion bus capabilities—connect up to eight Converge Pro units together and use up to 64
