More info

This new version uses more surface components, and a revised power supply (simple diode bridge for ground loops).

The input stage now accepts RCA and XLR signals with an AOP 5532.

Based on the architecture Class-T of the famous brand TRIPATH, this AUDIOPHONICS amplification module is characterized by a high quality reproduction for a very compact product.

The chip TA2022 integrated, it is possible to achieve 2 x 90 Watts under 4Ω with a level of harmonic distortion extremely well controlled since not exceeding 0,1%.
A power that does not sacrifice in any way the precision of this circuit prodigy renowned connoisseurs for these musical virtues.

To protect your speakers, this card has a protection circuitagainst the possible presence of a continuous component.
A timer also avoids unpleasant noise when switched on.

Jumpers are used to select the balanced (XLR) and unbalanced (RCA) inputs.

This version is now bridgeable to reach 150W under 4ohm.

Warning, this amplifier may be sensitive to radio interference from FM radios and tuners./ P>

Si on regarde le signal sur une charge résistive de 8ohm le résultat semble catastrophique, bruit énorme sur 1/4 du signal (à la fréquence de découpe 650khz). Cela est du au manque de filtrage, mais il est inutile de filtrer plus car les HP ne sont pas des charges résistive.
A l'écoute le son est bon il supporte la comparaison sans problème avec le FSDD 120 (ampli classe AB à VMOS) que j'ai monté en parallèle.

Way to much noise
Have 2 of these Tripath Kits from 2 different batches and they both have a lot of selfmade noise.
Have tryed them with their own ground spear, without ground spear. In cabinet, and witout cabinet. With and without signal. With and without one of the bigger schaffner filters. With differetn speaker drivers. Nothing works, and allways with the same result. Thay have so much selvmade noise thats its audioble even when the music playing.

I have very sensitive speakers with active crossovers. So not recommanded for that usage. Even when connection a small 87db Scanspeak tweeter to the module with no other connections to the board theres a clear hizzzz fro the tweeter.

Really annoying as the modules when playing loud enough to overcome the noise/Hizzz are super good sounding. And very powerfull to. Each amplifier board are driving to 12" drivers with ease.

Thay are so noisy I have to order other modules. So thats 220Euro out the window for my project.

I think they wiil be good at smaller subwoofers and speakers with low sensitivty (below 87db)

ampli de qualité
Utilisé pour le moment avec un pre ampli FX Audio tube 01 pour essayer, le résultat est largement au dessus de mes espérances! Cet ampli alimente des Klipsch RF82, c'est excellent. La qualité de montage de la carte est très bonne. Les borniers HP sont un peu juste pour mettre une grosse section de câble. Dommage que la version complète DIY de cet ampli ne soit plus commercialisé, l'ampli tout monté est disponible et reste intéressant à ce prix.
