"Leaner, Cleaner, Greener amplification
Primare’s new UFPD (Ultra Fast Power Device) amplifiers represent a new type of purified Class D/switch-mode design which delivers a natural dynamic quality of sound across the entire audible spectrum while retaining an amazing energy-saving efficiency. The original Class D modules worked well as compact bass amplifiers but proved to be inherently unstable when asked to do ‘hi-fi’ things like accurately reproduce a female voice or percussion instruments: distortion at 7kHz could be as much as one hundred times the level at 1kHz. UFPD has the ability to apply a constant loop gain across the entire audio band, treating all frequencies with the same level of care, and producing a response which is consistent regardless of load. This means that UFPD is able to drive any speaker, creating a vividly natural rhythmic sound while keeping power consumption at a fraction of that used by a traditional amplifier. With UFPD, Primare has inspired a new generation of smaller, more powerful hi-fidelity amplifiers, perfect for our environmentally conscious multi-channel age. Download the PDF for more information."
