The Donizetti Anniversary power amplifier, designed by AIRTECH laboratories, continues the legacy of one of Audio Analogue's historic products. It is a high-power stereo amplifier delivering 250W into 8Ω, with output power doubling as impedance is halved, allowing it to drive virtually any loudspeaker with ease.
The amplifier features a fully dual-mono configuration starting from two specially designed 1200VA toroidal transformers with very low stray magnetic flux. It uses the SeGeSTA (Single Gain Stage Transconductance Amplifier) configuration followed by a group of four transistors that provide the required current without affecting the performance of the gain stage.
The amplifier makes no use of global feedback. Its four-layer printed circuit board is designed so that the input signal never crosses the output signal, while the amplification stages are positioned as far as possible from the power transformers. Premium components include military-grade resistors, AIRTECH plastic capacitors, 7N OCC pure copper internal wiring and gold-plated pure copper output connectors.
Donizetti Anniversary can also operate in mono bridge configuration, delivering more than 1000W into an 8Ω load.
Key Features
- 250W into 8Ω with power doubling as impedance decreases.
- Fully dual-mono design throughout the amplifier.
- Two 1200VA toroidal transformers with very low stray magnetic flux.
- SeGeSTA amplifier topology (Single Gain Stage Transconductance Amplifier).
- Zero global feedback circuit.
- Four-layer PCB layout optimized for signal integrity.
- Premium components including AIRTECH capacitors, military-grade resistors, 7N OCC copper wiring and gold-plated copper connectors.
- Mono bridge operation with more than 1000W into 8Ω.
Technical Description
The Donizetti Anniversary features a zero-feedback circuit, fully balanced stages, dual-mono architecture and a discrete component design.
The output stage uses twelve bipolar transistors per channel with 56,000µF filter capacity per channel. Oversized military-grade resistors minimize thermal distortion, while AIRTECH-specification audiograde capacitors and microcontroller management complete the design.
Available in natural aluminium and satin black.
