QSC make the best amps
Geof H., 29.05.2013
If you want an amplifier that won't let you down and sounds great no matter what you throw at it then you won't go far wrong with QSC.

I have several QSC amps and they all perform beautifully. This one is installed in a church driving a pair of JBL SB-2 and 4 control1 speakers and the sound is fantastic.

Allroundendstufe - günstig, und hält.
Alexander388, 19.10.2009
QSC ist einer der größten Endstufenhersteller Weltweit - auch die haben mit der RMX Serie eine günstige Touringendstufe auf den Markt gebraucht.

Die Endstufe verfügt über frontseitige Potentiometer um den Pegel einzustellen und rückseitig schaltbare Filter und Limiter. Beides funktioniert einwandfrei. Der Limiter wurde auch schon bei den alten USA Series Amps verwendet - somit bekommt man hier bewährte Technik mitgeliefert.

Klanglich gut, im Bass etwas Schwach auf der Brust, wenn man beginnt die Endstufe zu Brücken oder an 4 Ohm Singlekanal fährt. Im 8 Ohm Mode recht OK.
Mitten und Höhen bringt sie klar und druckvoll rüber und ist somit auch sehr für diesen Zweck zu empfehlen. Stellt man dies dem Preis gegenüber sind sie aber auch im Bass eine empfehlung Wert im Gegensatz zu ähnlichpreislichen Konkurrenzprdoukten.

Es sind mehrere Baugleiche Endstufen auf dem Markt, welche bei näherem Hingucken nicht Ident sind (Haltbarkeit).

Steckt man von der Endstufe mehrere in ein Rack ist es ratsam sich über Ersatzbandscheiben gedanken zu machen - das macht keinen Spass! Somit eher als Monitoramp in einzelnen Racks, Festinstallationen oder maximal 2 Wege Systeme zu zweit in einem Rack verbaut empfehlenswert.

Ganz so super sind die frontseitigen Potis. Nach einiger Zeit (egal ob Touringeinsatz oder Fixinstallation) beginnen bei der Serie die Kanäle an zu spinnen (werden leiser, fallen komplett aus). Schuld daran sind die Potis vorne.
Diese kann man mit Kontaktspray etwas Reinigen, austauschen, sofern man das passende Ersatzteil bekommt oder auch einfach entfernen und auf der Leiterplatte zwei Pads mit einen kurzen Draht verbinden. Dann ist man das Problem los und hat wieder Freude an der günstigen QSC Endstufe.

Fazit: Günstige sehr brauchbare Endstufe. 2 Ohm stabil ohne Probleme. Einizges Manko sind billige Potentiometer an der Frontseite, die mit dem Alter der Endstufe Probleme machen. Problem lässt sich lösen.

L'ampli passe partout !
Bernard W., 19.05.2011
Aprés avoir testé nombre de produit chinois en termes d'amplification j'ai enfin sauté le pas et j'ai fait l'acquisition d'un véritable amplificateur. Mon choix s'est directement porté sur un ampli QSC. J'ai choisi cette marque et ce modèle car il a fait ses preuves dans le monde du spectacle. Bien que ce ne soit pas le haut de gamme de chez QSC, cet ampli peux tout de même être mis au rang du matériel professionnel. Il permet de poussé à peux prés n'importe quel enceinte ou caisson de cette gamme. Sa puissance est honorable et le son est bon au vu du prix au quel je l'ai acheter. J'en suis vraiment satisfait, c'est véritablement un ampli passe partout ! Seul bémol : son poids.
Oui, c'est un ampli pro donc le poids va avec mais pour l'avoir maintenant testé dans plusieurs conditions bien différentes, extérieur/intérieur, concert/gala/soirée il ma toujours semblé être un bon choix car il a toujours tenu la longeur même aprés plusieurs heures de fonctionnement à forte puissance.
Je recommande donc cet ampli à tout acheteur voulant un produit pro à un bon prix, bref un produit qui fait son boulot !

Gran etapa.
SM57, 08.10.2012
Buen amplificador de potencia, que ha sido la base para las posteriores copias y clones chinos, tanto de empresas originales, como del mercado pirata paralelo.
Etapa con buen diseño interior (funcionamiento y ventilación) y exterior, algo pesadita, sonido limpio y robusto, y en general un muy buen producto totalmente recomendado.
