Distorsionsfri

Distorsionsfri is a Swedish term meaning distortion-free and is used in audio and electronics to describe equipment or signal paths that minimize nonlinear distortion during sound reproduction. The term is not an absolute guarantee; it is a relative designation based on specified measurement conditions, test signals, and listening levels.

Common metrics used to quantify distortion include total harmonic distortion (THD) and THD plus noise (THD+N). Distorsionsfri devices strive for very low THD values, often below 0.1 percent at typical output powers, though performance varies with frequency, amplitude, and load. At higher frequencies or harder-to-drive speakers, distortion can increase.

Achieving low distortion involves design choices such as negative feedback, careful circuit layout, high-quality components, and stable biasing. In amplification, push-pull configurations, linearized stages, and power supply regulation help reduce nonlinearities. In digital-to-analog conversion, high-resolution DACs, clocking accuracy, and matching of channels contribute to lower distortion. System-level techniques, including proper impedance matching and avoiding clipping, are also important.

Distorsionsfri is frequently used in consumer hi-fi, home theater, and audio-testing contexts. While it conveys a desirable attribute, buyers should consult specific distortion figures at defined conditions rather than relying on the label alone, as perceived sound quality depends on many factors beyond measured distortion.
