Description générale : Je vends ce très bon bloc de puissance car je ne l'utilise plus que pour alimenter une paire de surrounds maintenant

On peut bridger les canaux 3-4 et 5-6 pour une puissance de 350W/8ohms, on peut également diriger les signaux des canaux 1-2 vers 3-4 ou/et 5-6.
Il pèse dans les 30kg et peut alimenter des enceintes gourmandes !
