Two 3-rackspace models provide 2000 to RMX amplifiers 2500watts per channel at 2 ohms. All six models feature a compact chassis less than 16" deep. include a comprehensive set of features including XLR and 1/4" balanced inputs, Speakon and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance. RMX5050 QSCs RMX5050 power amplifier represents state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile entertainers, the RMX5050 is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability. RMX4050HD Like its smaller sibling (the RMX1850HD), the RMX4050HD is one of two RMX heavy duty models designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. Both the RMX5050 and RMX4050HD feature a 3-tier Class H design that is extremely efficient at real world power levels. Less AC current is wasted and more available current goes into producing useful audio power. 120 volt versions of the RMX4050HD accomplish all this with a standard 15 amp plug.

switch settings shown. When the filter is turned off, a 5 Hz rolloff protects against DC or deep sub-audio inputs. WHEN TO USE IT (OR NOT) As a rule, your speakers will sound better with proper filtering. Unless you already have filtering in a preceding device, match the setting to the low frequency rating of your speakers. Vented (bass reflex, ported, etc.) speakers are especially sensitive to cone over-excursion at frequencies below their rated limit. The 50 Hz filter works well with most compact full-range speakers, and has a slight boost at 100 Hz for greater fullness. The 30 Hz filter is intended for subwoofers and large full-range cabinets. The "off" position should be used only for applications such as studio playback monitoring, where you need to know if there are unwanted sub-audio signals present in your mix.

Parallel input mode

WHAT IT IS The "Parallel Input" switches let you operate the amplifier in parallel mode, delivering the same signal to both channels without using a Y-cable. Each channel drives its own speaker load, with independent gain, filtering, and clip limiting. Set switch positions 4 and 5 "ON" to couple the inputs together. Turn the switches off for stereo, bi-amping, or other 2-channel modes.
INPUT IMPEDANCE: 12K BALANCED INPUT PINOUT

Mode entres parallles

DESCRIPTION Les interrupteurs "Parallel Inputs" vous permettent d'utiliser l'amplificateur en mode parallle, o le mme signal est livr aux deux canaux sans avoir utiliser un cble "Y". Chaque canal amplifie le signal indpendamment, avec ajustements propres de gain, de filtre, et de limiteur. Ajustez les interrupteurs 4 et 5 en position "on" pour joindre les entres des deux canaux. Laissez les interrupteurs en position "off" pour utilisation en mode stro, bi-amplification, ou toute autre application 2 canaux. Lorsque les entres sont rgles en mode parallle, vous pouvez utiliser le connecteur de la seconde entre pour envoyer le signal vers un autre amplificateur. On appelle ce type branchement le chanage en guirlande, ou "daisy chaining". UTILISATION Joignez les entres (mode parallle) quand vous voulez contrler deux haut-parleurs avec des ajustementes de gain, de filtre et de limiteur partir d'un mme signal. Voir la page 12 pour les explications des modes d'opration.

With the inputs in parallel, you can use the other set of input connectors to carry the signal to other amps. This is often called a "daisy-chain." WHEN TO USE IT
Patching the input signal to additional amps
Parallel the inputs when driving two speakers with one input signal (parallel mode) while keeping separate control of both channels' gain, filtering, and limiting. Use them in bridged mono mode to patch the signal to additional amplifiers through the extra input jacks. See page 12 for an explanation of amp operating modes.
NOTE: If you're using a balanced signal, use only balanced patch cables; even one unbalanced cable will unbalance the entire signal chain, possibly causing hum. NOTE: Turn off the "Parallel Inputs" switches when feeding the amp two separate signals.
NOTE; si vous utilisez un signal symtrique, n'utilisez que des cbles construit cet effet, puisque l'insertion d'un seul cble asymtrique dans la chane rendra la chane asymtrique, avec tous les dsavantages de ce type de connexion. NOTE; dsengager les interrupteurs "parallel inputs" quand vous amenez des signaux diffrents aux deux canaux.
BITTE BEACHTEN SIE: Wenn Sie ein symmetrisches Eingangssig-nal anlegen, benutzen Sie auch ausschlielich symmetrische Kabel zur Weiterverbindung, da auch nur ein einziges unsymmetrisches Kabel das Gesamtsignal unsymmetrisch werden lt, was mglicherweise Brummen verursachen kann. BITTE BEACHTEN SIE: Schalten Sie den Parallelbetrieb aus, wenn zwei separate Signale eingespeist werden sollen.
NOTA: Si usa una seal balanceada, utilice nicamente cables adecuados. Un solo cable no balanceado puede afectar el recorrido de la seal y producir zumbidos. NOTA: Cuando alimente el amplificador con dos seales independientes, coloque el interruptor "Parallel Inputs" en la posicin de apagado"Off".

Problema: no hay sonido

INDICACIN: EL INDICADOR DE ENCENDIDO NO SE ILUMINA Revise el cable de corriente. Revise tambin el disyuntor sobre el panel posterior. Confirme que la toma de corriente funcione conectando otro aparato. Si se conectan muchos amplificadores a una sola toma, el circuito se sobrecarga y se desconecta. Una sobrecarga en el modo de puenteado en mono puede causar un apagado momentneo. Verifique la impedancia de carga (4 ohmios mnimo), o reduzca el nivel de la seal. Un amplificador que se apagada continuamente, puede tener una falla interna. Apguelo, desconctelo de la toma de corriente y llvelo con un tcnico especializado para su revisin.

Confirm that the AC outlet works by plugging in another device. If too many amplifiers are used on one outlet, the building's circuit breaker may trip and shut off power. An overload in bridged mono mode may cause the amplifier to click off for several seconds. Check the load impedance (4 ohms minimum), or reduce signal level. An amplifier which keeps shutting off may have a serious internal fault. Turn it off, remove AC power, and have the amplifier serviced by a qualified technician.
INDICATION: SIGNAL LED RESPONDING TO SIGNAL LEVEL If the yellow SIGNAL indicators are lighting normally, the fault is somewhere between the amp and the speaker. Check the speaker wiring for breaks. Try another speaker and cable.
INDICATION: DEL DE SIGNAL FONCTIONNENT NORMALEMENT Si les DEL SIGNAL fonctionnent normalement, le problme se situe entre la sortie de l'amplificateur et le haut-parleur. Vrifiez l'intgrit du cble de haut-parleur. Essayez un autre cble et un autre hautparleur.
ANZEICHEN: SIGNAL ANZEIGEN LEUCHTEN NORMAL Wenn die gelbe SIGNAL LEDs normal aufleuchten, liegt der Fehler an anderer Stelle zwischen Verstrker und Lautsprecher. berprfen Sie die Lautsprecherleitungen auf Unterbrechungen. Schlieen Sie einen anderen Lautsprecher mit anderen Kabeln an.
INDICACIN: EL INDICADOR LED DE "SIGNAL" SE ENCIENDAN AL DETECTAR EL NIVEL DE LA SEAL Si los indicadores LED amarillos de SIGNAL parpadean, la falla ocurre entre el amplificador y las bocinas. Revise los cables de las bocinas, e intente cambiarlas o cambiar los cables.

No sound (continued)

INDICATION: SIGNAL LED NOT LIT If the green POWER indicator LED is lit and the fan is running, yet the signal LEDs indicate no signal, check the input. Make sure the signal source is operating and try another input cable. Connect the source to another channel or amplifier to confirm its operation. Overheating will cause protective muting. The fan will be running at full speed and the chassis will be hot to the touch; sound should resume within a minute as the amplifier cools to a safe operating temperature. Check for proper ventilation. If the fan isn't running at all, the amplifier requires servicing.

ANZEICHEN: CLIP LED BLINKT Wenn die rote CLIP LED bei anliegendem Eingangssignal blinkt, kann der Verstrkerausgang kurzgeschlossen sein. berprfen Sie die Anschluklemmen auf eventuell herausstehende Drhte oder Brche der Isolation.
INDICACIN: EL INDICADOR LED DE CLIP PARPADEA Si sto sucede cuando entra una seal, la salida del amplificador puede estar en corto circuito. Vaya a los cables de las bocinas y revise si tienen alambres sueltos o averas en el aislamiento. 23
INDICATION: CLIP LEDs BRIGHT AND STEADY The amplifier is in protective muting. One second of muting is normal when the amp is turned on or off. Overheating will cause protective muting. The fan will be running at full speed and the chassis will be hot to the touch; sound should resume within a minute as the amplifier cools to a safe operating temperature. Check for proper ventilation. If the fan isn't running at all, the amplifier requires servicing.
INDICATION: DEL CLIP ALLUMES EN CONTINU L'amplificateur est en mode protection. La mise en sourdine pour une seconde est normale lors de la mise en tension et hors-tension de l'amplificateur. La surchauffe entrane la mise en sourdine de l'amplificateur. Le ventilateur tournera alors pleine vitesse et le chssis sera chaud au contact; le son devrait revenir sitt l'amplificateur refroidi temprature normale d'utilisation. Assurez une ventilation suffisante. Si le ventilateur ne tournait pas, l'amplificateur serait dfectueux.
