FM Acoustics Resolution 233 Harmonic Linearizer

Price CHF 29000

The FM 233 Harmonic Linearizer allow precise correction and linearization of non-optimal recordings. They do this in an absolutely unique way. For the first time bad resonances, colouration, noise, obnoxious sound and other limitations are improved without affecting the balance of the audio signal. While the characteristics and transparency of the original signal is kept pristine, attenuated parts of the music spectrum can be strengthened.

The method of operation is rather intriguing as the entire audio signal takes a direct path from input to output. The improvement is achieved by a unique additive/subtractive Linearizer bank that corrects aberrations. Using just five controls, any frequency (or group of frequencies) in the entire audio band can be optimized without negative influence inflicted on the original audio signal. Furthermore, the signal always remains purely in the analogue domain.

When looking at the front panel one could be reminded of an equalizer. However, the Harmonic Linearizer's mode of operation is different and avoids all limitations. The FM 233 are not used like an equalizer as every control is dynamically interacting with the others in a unique linear multi-parameter process. There is no ripple in the pass band and no phase shift/discontinuity, both of which are unsolved problems of equalizers.

Massive improvements in the reproduction quality of CD, DVD, Tape, LP and any other source are now reality. The improvements are described anywhere from "truly amazing" to "incredible".
While some near perfect recordings will not need much linearization, good recordings will become great, mediocre recordings will become rather nice and some downright unlistenable recordings will become listenable. The improvements are rather intriguing and must be experienced to be fully realized.
