The Gefen TV Auto Volume Stabiliser uses Dolby Volume, which is a technology designed to intelligently 'normalise' loudness to avoid the annoying volume jumps familiar to late-night telly addicts, when broadcasters turn up the sound for adverts. The tech, which was modelled on psychoacoustic research conducted by Dolby, is integral to recent TVs, AVRs and this Volume Stabiliser.
