A brief Devialet dictionary
Every time a Devialet comes to visit, it brings with it a host of acronyms, which is all the more surprising from a French company, which might be thought unlikely to rack up so many initialisations based on English words. A few are new to the Dione; others are established technologies used on other products. Allow us to lexicographically enlighten you…
ADE (Advanced Dimensional Experience) is a signal processing algorithm which Devialet claims to have patented. It “combines ingenious speaker placement detection and advance digital filters to deliver superior multichannel audio through beamforming techniques”.
ADH is not an attention issue, but Devialet’s longterm analogue-digital hybrid amplification technology (boldly, indeed, called the world’s first hybrid amplification technology. The way they explain it, four digital amplifiers provide the grunt of amplification, while an analogue amplifier “determines the load’s output voltage, correcting and completing the signal the digital amplification delivers”. This, the company claims, combines analogue precision with the power and efficiency of digital.
AVL “adjusts lower sound levels for a more enjoyable viewing experience”, presumably providing a night-mode where you’ll shake the house a little less, although Devialet also seems to intend it to overcome the common scenario where movies mixed for the theatre have home viewers turning them up to hear dialogue then down again when the explosions start.
SAM is Devialet’s Speaker Active Matching technology, one of the earliest to emerge in this regard, and designed to overcome the differences between speakers whereby the same signal sent to different models produces unpredictably different acoustic pressures. Dynamic SAM control corrects this by adapting the signal to the characteristics of the speaker, improving linearity and maximising SPLs, while ensuring the system stays within its limits.
SPACE (not likely to be an actual acronym, but like ORB, randomly capitalised) actively upscales any stereo signal to the 5.1.2 multichannel configuration of the Dione.
