FLUO™ is the pursue of accuracy, integrity, and honesty to faithfully reproduce any musical event. Thus, the design and material usage of the products are carefully considered and purposeful.

The FLUO™ Single Die metal-oxide-semiconductor field-effect transistor concept for audio power amplification was first conceived by Ole Lund Christensen in 1995, it was a world first.

Using a single transistor giving a single audio current path, Christensen was able to deliver 200 W in 8Ohm with no need for many parallel transistor current paths to the loudspeaker, thus creating astonishing musical accuracy. His unique concept been reborn, redefined, reengineered in a new range of power amplifiers, that push the limits of musical realism. Designs which deliver absolute musical accuracy.

High grade, high current semiconductors are used, these offer more power, and much more current than any standard Hi-Fi transistor. Other high-power amplifiers use multiple transistors coupled together to create the needed power and current due to their weak power and current handling capabilities. These normal audio transistors have a fundamental problem which is limited current, this compromises their ability to deliver precise amplification. Even at 10% of their maximum current they create distortion.

FLUO’s unique Single Die semiconductor design offers 388 Ampers of peak current, and around 450 Watts. This allows the amplifier to function without stress. If a FLUO™ amplifier is loaded with a 2 Ohm loudspeaker it will easily deliver the required 38 Ampere current, as the FLUO™ semiconductor can deliver 10 times more than is required.

Fast Linear Ultimate Operation (FLUO™) has two objectives, firstly to keep the output of the amplifier correct no matter what level and frequency it receives. Secondly the output is a constant linear factor of the input, thus the two are always in harmony. It is the purpose to amplify the signal with total linear accuracy, which gives total purity.

The moment an amplifier design requires many transistors to deliver the power, the signal purity is lost as there will always be differences between each transistor, thus the current is dispersed without enough control. Consider having a single conversation or a conversation with 10 people all speaking at once.

The single path of resistance through the FLUO™ MOSFET is extremely low, 0.022 Ohms. This allows the amplifier to control the lower frequency range of the loudspeaker far more accurate with more precision due to its grip on even 2 Ohm heavy cone low frequency woofers.
