A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio input into a pulse train. The audio escapes through a simple low-pass filter into the loudspeaker. The high-frequency pulses, which can be as high as 6 MHz, are blocked. Since the pairs of output transistors are never conducting at the same time, there is no other path for current flow apart from the low-pass filter/loudspeaker. For this reason, efficiency can exceed 90%.
In basic Hypex amplifiers match with every pre-amplifier, for tube pre-amps please refer to the chapter "Cables and connections".
In principle Hypex amplifiers match with every loudspeaker, of course you need to match it correctly. Our advice is to use an amplifier which is capable of providing a little more power than your speakers require. Of course, it is not required to have a very powerful amplifier, at least take an amplifier module which is capable to provide the power a speaker can handle. If you use an undersized amplifier, you can imagine the amplifier has to run on top performance all the time with risks of clipping and can even damage your valued audio equipment.
UcD™ amplifier modules, worldwide well-known and respected for their performance. Learn more about our UcD™ technology at the Technology page. 
A SMPS is a high efficiency Switch Mode Power Supply specifically designed to be used in combination with our amplifier modules from the UcD™ and NCORE® Family. These can be used for mono and stereo setups as well as for multichannel applications.

NCORE® amplifier modules, NCORE® technology combines the stability of UcD™ with improved load-independence, lower distortion, and lower output impedance.  A new control loop ups the loop gain by 20dB across the full audio range without sacrificing stability.  NCORE® is the first Class-D amplifier not just to nudge the best linear amplifiers, but to surpass them in every aspect relevant to sound quality.

A Fusion Amp is an aluminum plate which contains a mounted DSP and 1, 2 or 3 amplifiers with on board power supply. To be used in active loudspeakers and subwoofers. Also called a plate amplifier.
