The Dolby Lake Processor offers a visionary approach to controlling and optimizing any
loudspeaker system in any venue, while simultaneously improving the sound quality.

The Dolby® L a k e® Processor marks the next generation in

unsurpassed audio quality and the most advanced loudspeaker
processing available, it will instantly improve the sound of
any system. Effortless control is provided through wireless
