More info

This Stereo Amplifier Module is based on the use of a pair of high-power transistorsTDA7293developed by the Swiss firm ST MicroElectronics.

It is capable of delivering a continuous power of 2x 100W under 4Ω.

Equipped with a very high thermal stability, it is equipped with a sophisticated protection system against overloads and overvoltages.

The filtering is ensured by 4 electrolytic capacitors 50V Chemi-Con of 5600uF each.
Finally, two MKP capacitors of 250V 3.3μF each and 2 Nichicon of 50V 220μF are added.

It has a speaker protection circuit UPC1237 with Omron relay.

Bien, aigus un peu durs, montage pas facile.
Ampli pas très facile à monter à cause de la position des amplis sous le circuit imprimé. Le son est un peu dur, pas si mal pour les graves qui sont très tendus, mais des aigus assez durs. Une belle image stéréo. Donc ampli à ne pas mettre derrière des tweeters métalliques (titane, alu), privilégier un gros tweeter tissus. Peut se résoudre avec une grosse résistance de 1 ohm en série avec l'enceinte.
