Behringer K900FX

Keyboard / PA Amplifier

With 90 Watts of power it should be a challenge to reach its performance limits! This 3-channel PA / keyboard amplifier in a bass reflex housing has a powerful original 12 ”BUGERA ™ speaker and a specially developed 1” tweeter for a clear, unadulterated sound - perfect for your gigs.

An internal 24-bit effects processor is on board and offers 100 presets such as reverb, chorus, flanger, delay, pitch shifter and various multi-effects. Our groundbreaking FBQ feedback detection shows feedback frequencies instantly, making it easy for you to avoid feedback problems.

In addition, the K900FX offers complete 3-channel operation with separate volume control and one FX Send connection per channel as well as an additional XLR microphone input (channel 1) for direct connection of dynamic microphones. An integrated 5-band graphic EQ gives your sound the finishing touch.

Sehr gute Leistung bei geringem Preis.
jaguar1983, 10.10.2009
Ich habe mir den Behringer K900FX Keyboard Verstärker sowohl für den Gebrauch zu Hause als auch für den Live-Gebrauch gekauft.

In beiden Situationen bin ich äußerst zufrieden. Die überaus vielen Effektmöglichkeiten benötige ich vorallem im Bandproberaum und daheim, denn hier spiele ich kleinen Räumen und möchte evtl. verschiedene Hall-Effekte benutzen. Der zusätzliche Mikrofon-Eingang war für mich insbesondere sehr hilfreich bei Live-Auftritten, da man sehr schnell ein Mikro anschließen kann und somit spontan mit einer Sängerin/einem Sänger musizieren kann. Auch kurze Ansprachen lassen sich dadurch leicht machen.

Der Sound klingt sowohl beim benutzen des Keyboards als auch für Gesang sehr gut. Überaus nützlich ist auch der Line-Out, für das seperate Aufnehmen des Gesamt-Outputs des Verstärkers während eines Konzerts. Auch der CD-In kann leicht verwenden werden um während einer längeren Pause bei Auftritten, z.B. einen MP3-Player anzuschließen. Mit passendem Kabel ist dies sehr einfach.

Ein Problem habe jedoch festgestellt, wobei ich noch nicht sicher bin, ob es mit dem Kabel oder dem Verstärker selbst zu tun hat. Manchmal kommt es nämlich zu seltsamen Knack/Klick-Geräuschen (wie bei Plattenspielern), diese treten allerdings nur sehr selten auf und stören mich persönlich nicht wirklich. Zumal diese auch bisher nie bei Konzerten aufgetreten sind. Vielleicht hat es mit schlechten Lüftungsverhältnissen zu tun, da zu nah an der Wand etc.

Insgesamt kann ich den Verstärker nur empfehlen, da er sehr viel Leistung und Features bietet für einen vergleichsweise sehr geringen Preis.

Un todo terreno.
Informática y Formación Gallega S.L., 18.03.2013
Se trata del tercer amplificador de Behringer que compramos. Un 450, un 1800 y finalmente éste que se ha escogido por ser de los modelos que permiten "pincharlo" en una pata de altavoz el de mayor potencia.

A favor de estos equipos tengo que en los modelos con tweeter el sonido es un poco mas claro siendo la potencia suficiente para locales de tamaño mediano. Por supuesto la potencia real no se corresponden con los número del modelo pero son muy pegadores.

El mezclador integrado hace que en la mayoría de los casos sea innecesario emplear un mezclador externo. La entrada de micro lleva phantom, no a 48 pero si con una tensión suficiente para la mayoría de los micros de condensador y cajas de directo activas.

Los efectos integrados son iguales que cualquier otro efecto integrado actual. Reverbs y delays bastante usables, algún octavador,... Pero únicamente podemos ajustar el nivel. No es posible ajustar ningun otro parámetro.
De todos modos tenemos un montón de posibilidades y nos ahorra un reverb externo.

El sonido es bueno en general aunque no es comparable a cajas de mas alta gama. Suficientemente bueno para el precio que tiene pero algo falto de matices para un piano eléctrico bueno, por ejemplo.

He tenido que reparar el 450 (un modelo inferior) para cambiar el encoder de la unidad de efectos y además de poder comprobar que la construcción mecánica es muy buena puedo decir que la circuitería interna es muy limpia y el ampli de potencia (híbrido) perfectamente reparable en cualquier servicio técnico. El encoder roto cuesta 2 euros por internet y el resto de repuestos deberían ser fáciles de localizar en el mercado por poco precio.

Para mi no es un punto negativo pero me parece apropiado indicar que estos equipos pesan bastante. La madera es gruesa y pesan.

Globalmente me perece una buena opción de compra.

Une entrée ne marche plus au bout de 3 ans d'une utilisation plutôt modérée, à la maison qui plus est. La construction à l'air robuste pour ce qui est de la boîte, j'en doute concernant l'électronique. Le son est ok pour bosser, rien d'extraordinaire mais ça fait le job, un équalo et quelques effets (delays, reverbs...) en prime c'est toujours bien même s'ils ne sont pas fameux. Claviers et guitares sortent à peu près, pour les voix c'est plus raide. À prendre si petit budget mais ne pas s'attendre à l'affaire du siècle.
