Donizetti
Power amplifier

The Donizetti Anniversary power amplifier, designed by Airtech laboratories, proposes another historic products of Audio Analogue. It is a high-powered stereo amp and with its 250W on 8Ω, that double by halving the impedance, Donizetti is able to drive any speaker perfectly.

The amplifier has completely dual-mono configuration starting from the two toroidal transformers of 1200 VA each, specifically designed to have very low lost flow. It uses our SeGeSTA configuration (Single Gain Stage Transconductance Amplifier) followed by a group of four transistors to provide all the necessary electricity without affecting the performance of the gain stage.

The amplifier makes no use of global feedback. The four-layer printed circuit board has been designed so that the input signal never crosses the output signal and that the amplification stages are as far as possible from the power transformers. All the components are of the highest level: military standards resistors, Airtech plastic capacitors, wiring connections made of 7N OCC pure copper and gold plated pure copper output connectors.

Donizetti Anniversary can also be used in mono bridge configuration achieving even more extreme performance and an output power that reaches over 1000W on 8ohm impedance.
