Primare’s UFPD technology provides for the possibilities of a full-range ‘audiophile’ Class D design. It is a new and significant Class D technology which is remarkable for its performance consistency across the entire audio bandwidth. Traditional Class D amplifiers have a signature response, which is fabulous at low frequencies but can sound harsh and brittle at higher frequencies due to circuit instability produced by insufficient feedback. UFPD actively adjusts the feedback required to deliver a higher level of gain across the entire audio band, maintaining performance irrespective of load (impedance) variations. Primare’s UFPD treats all signals equally, keeping distortion very low at all frequencies. With a very wide ‘load independent’ frequency response UFPD is able to drive any speaker while maintaining control and accuracy.
