Primare
I-22
Integrated Amplifier

Overview

The Primare I22 is an upgradable two x 80 watt integrated amplifier utilising twin proprietary Ultra-Fast Power Device (UFPD) power modules. UFPD’s performance results in a naturally fast, clean and agile sound over a much wider frequency range and with exceptional headroom. Ecologically the Primare I22 integrated amplifier is far superior to conventional Class A/B designs being extremely efficient without generating excessive heat. In addition it provides a special eco-friendly standby mode of just 0.3W. Clearly visible on the Primare I22’s white dimmable VFD display is a versatile menu, which allows the renaming of inputs and the setting of operational parameters for each – volume, balance and power-up level for example.

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.
