Lexicon To Demo QLS SD Surround Processing



Lexicon will go to the CEDIA Expo with a surround-sound preamp/processor incorporating Harman’s proprietary Quantum- Logic Surround 3D (QLS 3D) post processing delivers up to 12.4 channels of surround sound from mono, stereo and multichannel sources.

The flagship four-rack-tall MP-20 media processor is scheduled to ship in the first quarter at a price above the original $11,000 to $14,000 price of its predecessor.

QuantumLogic Surround adds five height channels to typical 7.1-channel home theater systems. The five additional channels include two rear-height channels, a center-channel height speaker above the center-channel speaker, and two front-height channels that also deliver front-wide spatial information.

Four independent subwoofer outputs are designed to deliver accurate bass response in a wide sweet spot in home theaters with multiple seats.

For the rest of the frequency range, QLS will also widen the sweet spot to cover multiple seating locations, optimize the sweet spot for specific seating locations, digitally compensate for less-than-ideal speaker locations, and move listeners from an audience location to an onstage location.

The technology’s center-focus control anchors dialog to the center channel for listeners who are sitting off-axis to one side of the room or the other.
