HARMAN’s Lexicon introduced its QLI-32 Quantum Logic Immersion cinema processor, designed to deliver up to 32 channels of surround sound in professional cinema applications. The new QLI-32 interfaces with a theatre’s media source and existing cinema processor to provide a multi-dimensional listening experience with left, centre, right, surround, rear and height channels, all via HARMAN’s proprietary Quantum Logic Immersion surround-processing technology. In doing so, the QLI-32 provides theatres with a cost-efficient and easily deployed upgrade path to significantly-improved immersive cinematic sound.

“Our new QLI-32 offers an effective way for theatre owners to upgrade to immersive surround sound with a product that is fully compatible with existing cinema processors and is competitively priced,” said Dan Saenz, Business Segment Manager, Installed and Cinema Sound, HARMAN Professional. “It can be easily integrated into an existing theatre or specified as part of a new installation.”

The Lexicon QLI-32 utilises HARMAN’s exclusive Quantum Logic technology to provide up to 32 channels of immersive surround-sound audio over BLU-link from any mono stereo, 5.1- or 7.1-channel program material. The Lexicon QLI-32 uses exclusive signal processing techniques to actively analyse the acoustical information in the audio mix and re-create a full three-dimensional sonic environment with width, depth and height by identifying and positioning objects in the sound field – all without adding elements to the original mix. Because the QLI-32 works with existing audio systems, installation costs are reduced and any stereo or multi-channel content can be made immersive.

The QLI-32 features an 8-channel analog 25-pin connector, two 8-channel AES RJ-45 inputs, a BLU-link (2 x RJ-45) input and a BLU-link (2 x RJ-45) output. It also provides an Ethernet port and RJ-45 control connections. The QLI-32 provides Auto EQ per SMPTE 202 and offers 1/3-octave graphic EQ for each of its 32 output channels as well as parametric low-frequency EQ. The QLI-32 can be easily configured via its web-based interface and its simple front-panel control layout provides ready indication of operational status. Measuring 1U rack space high, the QLI-32 installs easily into an equipment rack.

Quantum Logic Immersion uses specialised algorithms to extract signal and reverberant streams from the original recording. Individual voices and instruments, as well as reverberant spatial information, are identified and then re-authored into a precise multichannel sound field. QLI combines the individual signal streams using patented filter bank technology and psychoacoustic modelling to create an immersive multichannel listening experience with exceptional clarity, detail and image specificity.

The Lexicon QLI-32 Quantum Logic Immersion processor is currently available.
