Informatie
The U500DC effortlessly delivers a huge 500W @ 4 Ohms stereo, and the all-new passive cooling system guarantees that the only thing you’ll ever hear is the music as it was originally intended.
Our team of engineers have been working at the top level of the audio design industry for nearly 3 decades and have supplied amplification to countless studios, stages, theatres, festivals, stadiums, and
nightclubs. Drawing on this experience and with access to the latest technology, we have created the ultimate amplifier
Highly Engineered Power Supply
An oversized linear/toroidal design has been implemented here to achieve the ultimate delivery of power. A low noise custom wound 500VA transformer ensures that the U500DC is never stressed and has next to no losses. It operates as two monoblocs with the ability to provide huge peak power, which
is delivered into two 27,000uF storage capacitor banks, ensuring ultimate stereo separation and powerful low-end propagation.
Ultra-Sigma Design Topology
A completely new push/pull output stage was developed over three years and refined through multiple listening tests. Our modern take on the class D topology is based on Sigma-Delta modulation, with
supersonic switching techniques 20 times higher than the human hearing range. It reduces resistive losses 100 fold compared to class AB designs and totally eliminates crossover distortion (similar to
a class A amplifier). Overall control of the output stage is accomplished by a single feedback loop which helps the U500DC deliver it’s open, transparent, and expansive sonic signature.
Sonically Pure Input Stage
The input driver stage is a high-end, class A design which is complemented by full DC coupling from input to output. No Interstage coupling capacitors are used, only direct copper tracks or wires, any
DC input errors (if present) are eliminated by a single overall outer servo loop. This ensures total alignment of transients and unparalleled low-end response
