RE: Mes aventures audio
Dominique:
Le Marten a été presenté en 2011 et utilise la technologie AMS développé par Anaview mais avec une alimentation
linéaire.
Leurs argument commercial :
Using our revolutionary AMS technology, the M•Amp delivers a powerful, transparent, musical sound utterly free from distortion.
AMS (Adaptive Modulation Servo) was invented by Patrik Bostrom, founder of the design house Anaview AB in Sweden. The core of the Marten amplifier is an inverting globally self oscillating class d stage. This class d stage is a load independent wide bandwidth (-3dB @ 120 kHz) first order modulator, switching at 600 kHz, with a constant loop gain of 30dB all the way up to the switching frequency. The result is a true delay line, which displays very wide bandwidth and fast transient response.
The AMS is connected to the positive and negative inputs of the core amplifiers modulation stage, acting to eliminate the imperfections of the modulation. The gain of the core amplifier cannot be affected by the servo so the wide bandwidth first order behaviour of the class d modulator is perfectly preserved. The servo has flat 20dB gain up to 20 kHz, creating a constant linearity in the audio band.
To ensure no compromise to excellence is made, two independent channels are used in a balanced configuration.The result? A truly exceptional amplifier with a very wide bandwidth, ultra low noise/distortion, high output power and very low losses.
Les modules que j'ai acheter sont commercialiser depuis mi 2013, les modèles que j'ai reçu sont en REV E, la doc est celle de la REV D (page 36).

Oui,
Merci,
J'attends les pièces détachées (prises, châssis)
