AUDIOPHONICS PGA TA2022. DIY Amplifier Kit with Remote Control
This kit contains all the elements necessary to the assembly of a digital stereo amplifier based on the high performance circuitTRIPATH TA2022. This amplifier is equipped with the module PGAVOLwhich offers an input selector and volume control via the front rotary encoder or remote control.
The housing is completely drilled to incorporate the kit elements as easily as possible.No drilling is required. This realization requires very few tools to be able to be carried out.
The assembly is within everyone's reach and is a royal way to learn the joys of the DIY at a lower cost, with the ultimate achievement of a quality device, and the satisfaction of having made yourself the " one of the components of his Audio system.
Designed on aAUDIOPHONICS loads, this assembly is characterized by its musicality of high flight and its impressive power with regard to its compactness.
The chipTA2022integrated, 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%.
In order to exploit the possibilities of this circuit prodigy, we have chosen to integrate components of higher quality, such 12 ELNA capacitorsof each one1200uF / 63V, cleverly allied to MKP, as well as a generously sized toroidal transformer.

Projet très intéressant. Dommage que la conception globale n'ait pas été revue pour éviter les multiples condensateurs de liaison et optimiser le trajet du signal. j'aurais finalement préféré un vrai kit PGA (avec boitier perforé!) qui propose enfin une alternative correcte aux modèles chinois.
