Do not be fooled by the low price point - it's a garbage product. Warranty and repairs are outsourced to a third party called Music Tribe, please read their trust pilot reviews online and you'll be able to verify first hand that you're basically 100% out of luck. What's the use buying something cheap if it a) does not work and b) has zero product support? The usual joke with Behringer is that you get what you pay for, but here you get even less. Do not waste your money, these are awful prototypes that are not in wide circulation in Northern America for a very good reason - respected sellers and whole traders do not touch this product. Also, please see all the other 1-star reviews, this is not an isolated incident, it's a production run issue. Read more

purtroppo il riverbero non funziona e anzi quando attivato fa un rumore fastidioso, il ronzio di fondo è più alto di altri dello stesso prezzo. nota positiva il gain secondo me è molto buono. va bene per inizare se non usate il riverbero Read more

I just bought this AH40R amplifier, and immediately when I turned it on it started to sound a quite annoying hum, although it is not very high in power, it is also true that it is a sound that should not have the amplifier, so I'm returning it back and replacing with another one to check it out and see if I can have an amplifier without a humming honeycomb when just turn it on! I like this Behringer brand, actually I have bunch of products from them, I just don't wanna they disappoint me with this Amp, cuz I love its specs. Let's see next week... I'll be updating this comment and rating if I get what I'm expecting from this company. Read more

Potencia un 10, pero i+d ... hay mucho ruido en el altavoz, una pieza venia suelta y se escuchan como radios, voces de personas en el altavoz. No se si escribir a cuarto milenio, y es algo normal que pase esto. lo devolvi por la pieza que se escucha suelta al mover el altavoz, pero si no fuera por eso por el precio que tiene da bastante caña para ser 4'w, para un ensayo vale y para casa sobra potencia, la distorsionque da por el precio que tiene es buena. en fin si tienes poco cash y quieres ir tirando lo recomiendo, si te puedes permitir algo mejor compralo.

Beaucoup de bruit, mauvaise filtration du courant continue... Bruit (noise) du à une mauvaise filtration du courants lorsque les volumes sont à zéro ou à bas volume. Bruit Chuuuuuhh à bas volume. Très dérangeant à basse écoute surtout avec des headphone ! Ampli trop clair, basse inexistante. Je déteste. Read more
