AudioControl has announced that its latest line of receivers and processors will include Dirac Live Bass Control, for a more immersive home theater experience.


Dirac Live Bass Control uses machine learning and artificial intelligence to deliver more consistent bass across a room.

“Bass performance suffers when the sound waves from speakers and subwoofers start to bounce around a room,” explains Niklas Thorin, Dirac’s Head of Business Development. “Dirac Live Bass Control dynamically measures and phase-corrects speakers and subwoofers across all frequencies in order to produce superior bass clarity and enhanced bass tone evenness throughout a room. Home theater audio has never sounded so rich and precise, as users of AudioControl’s leading AVRs and preamp/processors can now attest.”

Dirac Live Bass Control, the latest addition to the Dirac Live family of acoustic processing technologies, aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout a room. It then identifies gaps in the sound waves and distributes bass evenly.

The innovative software also corrects the low-frequency sound waves produced by other speakers so that the bass produced by each speaker is in sync with the overall system.

This approach allows integrators more opportunities when it comes to placement of subwoofers in a space, to better meet a client’s interior design or aesthetic preferences.

“As a leading supplier of best-in-class home cinema receivers, processors and amplifiers to A/V specialists, we are excited to feature Dirac Live Bass Control as standard across our new Maestro X-Series processor platform and the majority of our XR Series receivers,” explained AudioControl CEO Alex Camara.

“Dirac’s new bass control technology will enable AudioControl to provide the very best cinematic experience by intelligently optimizing the subwoofers and speakers to the characteristics of each room.”

Dirac Live Bass Control is included with AudioControl’s Concert XR-8 and Concert XR-6 receivers and Maestro X7 and Maestro X9 preamp/processors. It’s an optional extra on the Concert XR-4 receiver.

Current AudioControl Concert receivers deliver six channels of user-configurable outputs for high-pass channels, height channels or additional subwoofers for optimising the movie experience. The step-up Maestro series offer 16 channels of balanced and unbalanced output.
