Es bastante comentado en foros USA lo inaudito de las mediciones del Yamaha. Sobre todo viendo que en otras revistas europeas miden la potencia a 5 y 7 canales dando valores que casi triplican los que publicaron en sound and vision.

Un saludo.

Mira. El Yamaha 2040 tiene practicamente la misma potencia que el 2050, y el 3040 la misma potencia que el 3050. La diferencia de potencia entre los modelos 20XX y 30XX es sobre el papel de tan solo 10W con lo que según lo que sale en Sound and vision el 3050 tendría unos 55-60w en cinco canales. Aunque es cierto que las medidas en sound and vision son a 8ohm mira el test que han hecho al 3050 en audiovision.de y saca tus propias conclusiones. Alguien ha medido algo rematadamente mal en el Yamaha y no parecen los alemanes. Más que nada porque el resto de receptores de otras marcas arrojan medidas similares a las de la revista americana.

Un ampli no entrega la misma potencia repartida entre una gama de 20Hz - 20.000Hz que si es a una sola frecuencia de 1KHz.... Todos sabemos que a 1KHz el rendimiento de cualquier ampli es mucho mas elevado. De ahí esas diferencias tan notables entre esas mediciones.

Un saludo del Oso

Por supuesto, hasta ahí llego. Pero me baso en que en sound and vision NO aclaran si las medidas son a 1khz o a toda banda. Pero al ver los resultados en audiovision.de de los otros receptores y comprobar que son casi identicos los resultados que los de soundandvision pues entiendo que los americanos solo miden a 1khz tb.

Un saludo.
