Product details

Hypex NC400 1x400W Ncore Monoblock Kit


The Ncore technology from Hypex is one the best amplifier technologies available. This class D technology provides extreme high-level performance on any playback level, regardless of load. The NC400 stands among the top of our amplifier module technology.


Besides impeccable performance, this kit features everything you need to build your own Ncore monoblock amplifier. The main parts are the NC400 amplifier module, SMPS600N400 switch mode power supply and the DIY Monoblock Case. The amplifier module and power supply combination enable the best performance available from the Ncore technology. The black anodized case provides good heat dissipation and a compact design.


Along the main parts, everything else you need to build a powerful high-quality monoblock amplifier is included. Assembly only requires proper positioning, around 25 bolts to be tightened and some connectors to be clicked.  Anybody comfortable with a screwdriver can build one of the best amplifiers available.

Whats In The Box



Q: I have a stereo system. Do I need two of these?

A: A monoblock is an amplifier that only has one channel. A stereo setup requires two channels; you would need two monoblock amplifiers for a stereo stetup. Compared to a stereo amplifier, this might seem cumbersome. However, a monoblock features a complete power supply for one channel. This allows for the best performance.


Q: Is there a stereo kit available?

A: There is no complete stereo kit for the NC400 available. Combining two NC400 amplifier modules, a SMPS1200A400 power supply and the SMPS1200A400 onto 2x NC400 Connection kit make a NC400 stereo amplifier. This is a bit more of a DIY approach, as you would need additional components (like connectors, binding posts and a case), but it makes a great project! For complete Hypex stereo kits, check out this Hypex UcD400 Stereo Kit and Hypex UcD180 Stereo Kit.


Specifications for: NC400 1x400W Ncore Monoblock Kit

  • Rated power output (RMS) The electrical power measured in watts (W) that an amplifier can output per channel, without damaging the amplifier or the output signal is çlipped'. RMS = Root Mean Square.

    1 x 580 watts at 2 ohms

    1 x 400 watts at 4 ohms

    1 x 200 watts at 8 ohms

  • Bridged power output (RMS) The electrical power expressed in watts (W) that an amplifier can output per bridged channel (2 x stereo to 1 x mono output), without damaging the amplifier or the output signal is çlipped'. RMS = Root Mean Squeare. -
  • Minimum load Shows the minimum load that an amplifier can control in ohms. A lower impedance of a speaker is not recommended if it is lower than the minimum impedance of an amplifier. An amplifier works best when the impedance of the speaker falss within the impedance range that the amplifier prescribes (for example, 4 to 8 ohms). 2 ohms
  • Signal-to-noise ratio (SNR) Shows the strength level of signal power compares to a level of noise power. Generally, higher values ​​means better specification. 125 dB

    The best choice (quality/price) for a class D amp

    Dit is een geweldig product! Deze klasse D versterker is serieuze concurrentie voor top klasse A versterkers en daarbij zeer zuinig en licht.
    Het laag en de detaillering hiervan is met name zeer goed: een zeer "strakke" basweergave. Bovendien is de dynamiek geweldig, waardoor je het idee hebt dat je naast het podium staat..
    Een aanrader!

    Kingt absolut neutral und dennoch kein bisschen langweilig. Hatte vorher ein 30 (!) mal so teures Röhrensystem; der NC400 sollte eigentlich nur zur Überbrückung für ein paar Monate bleiben - jetzt darf er langfrisig bei mir arbeiten.

    The amplifiers are fantastic! There is so little distortion that they are a perfect studio monitor amplifier. SoundImports were great to deal with: excellent communications and quick shipping. These are kits yet require no soldering, just basic hand tools. I'm happy to have discovered this company! Thanks, Graemme

    5 / 5

    Easy to build.
    Soundwise there is no sound I would say. They do really well with the Dynaudio Contour 30.
    Came from NAD C375 (which is good already).
    The NC400 have a much bigger stage and deeper room. Bass is slightly more tight.

    5 / 5

    Compared to my old AB amps the NC400 are much faster and more detailed soundstage. I hear new details everyday vhen listening to my old platters(cd's).
    I cannot say that I have heard anything better and then you have to realize that I have been principle serviceman for Krell and Audio Research so I have some reference experience.

    Easy and fun to assemble, and soundvise it could make some overrated American heavyweights to be very nervous.
    Heartly recommended

  • SS By Sebastian S. on 25-07-2019 13:52

    5 / 5

    - Very high surface / build quality
    - sturdy and high quality binding posts
    - neutrik XLR
    - no soldering required
    - very clean and controlled sound
    - beats much bigger class A amps easily
    - runs quite warm for class D

    - Aussergewöhnliche gute Verarbeitungsqualität des Gehäuses, sehr edele Oberfläche
    - kein Löten erforderlich, nur schrauben und stecken
    - hervorragender, neutraler klang mit jeder Menge "Druck"
