More power
The nuPower A is a Class AB power amplifier and our masterpiece in amplifier construction. Its massive appearance is not just for show, but part of the elaborate passive cooling concept. This allows the waste heat of up to two times 1150 watts to be tamed. With top technical values for signal-to-noise ratio and distortion values, we guarantee you good sound from soft tones to maximum level.
Details
Mono mode
The nuPower can not only be operated as a stereo power amplifier for two speakers, but also offers a switch on the back that turns it into an amplifier in mono mode with a fabulous 2200 watts peak power. This guarantees sufficient dynamic reserve for any application. In addition, you can switch between Cinch and XLR input and raise the damping factor by 6 dB for even more level.
Sets
The best match for the nuPower A is our nuControl 2 sound manager, which is an equal player not only visually but also in terms of noise behaviour. In addition, you will of course find the matching playback devices among our speakers that can handle so much power. For inspiration, we recommend our set offers for the nuPower A.
Class A amplifier
The nuPower A relies on a Class A amplifier coupled to the B-type for an energy-efficient solution, with minimal distortion and high signal-to-noise ratio. Thus, the completely analogue power amplifier set standards not only visually, but also technically. Its advantage: more dynamics with the same size.
Powerful power supply unit
The power supply of the nuPower A has to withstand high loads in order to provide up to 2300 watts for the power amplifiers. For this purpose, components from the automotive industry are used so that the corresponding currents can be fused and passed on. Your advantage: maximum reliability for a long-lasting product.
Full power
The nuPower A has a range of circuitry, for the best possible performance. Soft ramping is used to slowly draw the current after switching on, so that the fuse of your house installation does not drop. To prevent ground hum, there is the ground lift switch on the bottom. Your advantage: clever solutions that make everyday use less problematic.
Cutting belt transformer
The nuPower A does not rely on conventional toroidal transformers, as these build up a magnetic field in all directions. The advantage of the ribbon transformers is that almost no field is built up at the top. This is where the power supply of the nuPower A is located, so it can work without affecting the signal. Your advantage: less distortion and clearer sound.
Colours and design
Our nuPower A takes its cue from classic hi-fi forms and updates them. The large silver aluminum rotary knob stands out strikingly against the black housing and facilitates operation. Combined with the nuControl 2 preamplifier, the result is a harmonious combination that also convinced the design editors of Reddot and iF.

Der High-End Schreck
Die nuPower A treibt meine nuVero 170 an. Eine perfekte Kombination! Man muss sich um die Haussicherung kümmern, wenn man in der Schweiz wohnt (max. 13A ), aber dann funktioniert es tadellos.

nuPower a
Hallo Liebe Nubert Freunde, ich bin stolzer Besitzer einer nuPower a. Es gibt nicht viel zu sagen, für mich eine mega Endstufe! Preis/Leistung unschlagbar. Klang das muss man für den Preis gehört haben. Ich bin so was von zufrieden. Danke an die Fa. Nubert für so eine tolle Endstufe.

Feedback nuPower A, nuControl 2, nuVero 140
Die NuVero 140 entfalten in meinem 25 qm Dachgeschoss eine noch bessere Klangfülle als im Nubert Hörstudio in Duisburg. Die Lautsprecher haben Pegel und Dynamikreserven bis zur Vollaussteuerung. Natürlich kann der NuPower A hier auch seine Leistungsfähigkeit entsprechend ausspielen. Der NuControl 2 erzeugt in dieser Gesamtkombination ein sehr natürliches Klangbild und ermöglicht, durch die Digital-Lineare Abstimmung, ein unverfälschtes Klangerlebnis. Die Raummoden die gerade im Bassbereich in meiner Dachgeschosswohnung entstehen, können somit gänzlich entzerrt werden. Auch der Nubert Service nach dem Kauf ist hervorragen. Ein XLR Kabel von "In-Akustik" musste ich aufgrund eines Produktionsfehlers zweimal zurückschicken. Herr Siegle hat damals darauf hin die Bestände prüfen lassen und festgestellt, dass ich wohl zweimal den "Ausreisser" gezogen habe. Alles verlief Problemlos. Daher kann ich ohne weiteres als glücklicher Kunde feststellen das Nubert, von der Anpreisung der Produkte bis zum Klang, hält was versprochen wird. Das Wort "Ehrlich" wird meiner Empfindung nach nicht nur von den Produkten klanglich umgesetzt, sondern auch von den Mitarbeitern gegenüber Kunden sehr ernst genommen. Auch meine erste Bestellung bei Nubert, die NuBox 383, habe ich zuerst für die Verwendung als TV-Lautsprecher gekauft. Jetzt habe ich mein 2.1 System eines bekannten Herstellers der hauptsächlich für seine Drahtlosen Eingabegeräte für Computer bekannt ist durch die Nubox 383 ersetzt, dies hört sich für mich auch "Logisch" an, denn nun habe ich dort doppelt so viel Bass und Klangvolumen als mit dem 2.1 System.

Device type and recommendations for use
As a stereo power amplifier, the Nubert nuPower A combines enormous power with audiophile sensitivity. It is the ideal complement to a playback chain consisting of a source player, preamplifier and loudspeakers. The balanced construction throughout, the selected components and the careful signal routing enable a particularly high sound purity.
With a continuous output power of 2x 540 watts (4 ohms) and a generously sized power supply that provides up to 2,300 watts, the nuPower A drives even power-hungry speakers and fully exploits the acoustic potential of a high-end system. To maximize output power, the nuPower A can be operated in mono mode. In this application, two nuPower A are combined to power a pair of speakers. Up to 1,150 watts (4 ohms) are then available per channel. Despite this concentrated power, no increased distortion values occur even at full modulation. The signal-to-noise ratio of 117 dBA and the total harmonic distortion (THD) of only 0.002 % meet the highest demands for sound purity and are, in our opinion, unique in this price range.
We especially recommend the nuPower A in combination with our preamplifier nuControl as well as with the loudspeakers of our top series nuVero. However, thanks to its versatile connection options (including a pair of XLR inputs and high-quality fine-thread terminals) and its flexible design, it also works harmoniously with other preamplifiers and speaker models. In doing so, the nuPower A drives up to two pairs of speakers, alternately or simultaneously. The enormous load stability makes it irrelevant whether the speakers are 2-ohm, 4-ohm or 8-ohm.
Connections
The nuPower A features a pair of XLR inputs (balanced) and a pair of RCA inputs (unbalanced), allowing it to be easily integrated into a stereo system. At the speaker terminal with four pairs of fine-thread screw terminals, you can choose to drive one or two pairs of speakers in stereo mode or one speaker in mono mode. A trigger input in mini-XLR format is also available (cable included). A complete list of the connections can be found under "Technical Data".
Housing and design
Appropriate for a high-end product is also the design and finish of the nuPower A - executed in a shapely housing of partly brushed, partly blasted aluminum, which is coated in high-quality matte black. With a width of 43 centimeters, it fits perfectly into standard AV shelves. Visually, nuPower A and our nuControl preamplifier form a perfect ensemble.
Controls
The nuPower A has only two front panel controls: a speaker selector switch (operating modes: a, b, a + b) and a standby button located below it. The volume is controlled via the preamp. Switching between mono and stereo mode is done via a toggle switch on the back. A 28-page manual explains all options and offers typical application examples.
