OvervieW
The Converge Pro™ product line provides a complete sound system for collaboration, presentation, distance
communications and any other multimedia audio event.
The Converge Pro audio system is extremely flexible allowing it to be used in a wide range of applications, with superior
audio quality. This is the result of combining ClearOne’s proprietary Distributed echo Cancellation and ClearOne’s
advanced adaptive algorithms with powerful audio digital signal processing for automatic microphone mixing, signal
routing, equalization, automatic level control, compression and other audio processing functions. The Converge Pro
system uses a rapid configuration user interface for system setup, minimizing the time it takes to get a system up and
operational. The Converge Pro is the heart of custom installed audio systems.
for ease of use, Converge Pro systems facilitate local and remote PC setup, control, and diagnostics in addition to
compatibility with ClearOne Tabletop Controller and integration with popular control systems.
New Converge Pro enhancements
Next generation ClearOne
•
® Distributed echo Cancellation®— improves 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.
•
Advanced noise cancellation reduces background noise caused by fans, HVAC systems, and other relatively
•
constant background noise sources.
Signal processing with 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.
enhanced expansion bus capabilities—connect up to twelve Converge Pro units together and use up to 96
