LOG SoundEngine - Digitaler Signalprozessor

LOG SoundEngine. The future of audio technology.

DI Thomas Pfob - CEO von Sound & Electronics LOG GmbH

With the development of the revolutionary, fully digital LOG SoundEngine, we are taking the step into the future of audio technology.

All LOG systems offer an unprecedented experience, which allows music to express itself in all its diversity and naturalness.

LOG SoundEngine

The LOG SoundEngine is the most advanced audio technology in the world.
It is the heart of every LOG system and features lossless signal processing, ultra steep digital crossovers and a linear-phase, digital sound optimization.

THE FUTURE OF AUDIO TECHNOLOGY

Many areas of life are completely digitalized nowadays. Especially in the film and music industry, everything is digitally produced and mixed, but the technology of most loudspeaker companies is still based on analog concepts. The LOG SoundEngine is a step into the future, introducing a revolutionary, fully digital concept.

LOSSLESS SIGNAL PROCESSING

The consistent digital signal processing in the LOG SoundEngine minimizes the conversion of the music signal from digital to analog (and vice versa). The music signal is not affected thereby and is led losslessly from the source (output device) to the loudspeaker chassis. In contrast to analog systems, no losses occur, even if the distances between the source and the speakers are long.

DIGITAL CROSSOVER

Only loudspeaker chassis with optimal preconditions are used for LOG systems. Nevertheless, due to its physical design every chassis has its own sound coloration. The powerful processor of the LOG SoundEngine can not only digitally correct and neutralize these characteristics, but also precisely define the frequency range of the respective chassis. This is completely lossless and cannot be achieved with an analog system, where losses in the signal occur in each analog crossover.

LINEAR-PHASE PLAYBACK

Each correction usually causes phase shifts between the loudspeaker chassis. Since this correction takes time, distortions and other negative effects can occur in the frequencies. The LOG SoundEngine avoids these shifts and is capable of correcting timing differences between chassis digitally thanks to its high computing power. The signal is therefore phase-linear and reproduced without errors - a revolution in audio technology.

CLASS-D POWER AMP FOR EVERY CHASSIS

In all LOG systems, each chassis is digitally equalized and powered by its own high-performance Class-D power amplifier. Due to this high overall performance, there is no distortion or sound coloration, even at high volume.

TECHNOLOGY AND MUSIC IN HARMONY

Thanks to the innovative digital technology, the music is the main priority at LOG. For this reason, each loudspeaker is subjected to an elaborate tuning process, where, in addition to state-of-the-art technical measuring instruments, the human ear (the best of all measuring instruments) is of paramount importance. Only when a violin sounds like a violin and an orchestra sounds like an orchestra, technology and music are in perfect harmony.
