Audio Analogue "Bellini Anniversary" pre-amplifier

Line Preamplifier

The Bellini Anniversary preamplifier, designed in the Airtech laboratories, proposes another of historic Audio Analogue products. The only thing in common between this new model and the previous versions of the Bellini is the name, while the project and the technical solutions used are completely new.

These new features include the power stage designed using inductive-capacitive filtering to minimize power disturbances. The inductance of the filter has been designed and manufactured specifically for this device. The amplifier stage, called Se.Ge.STA (Single Gain Stage Transconductance Amplifier), has been designed to make the preamp even quieter while maintaining the structure completely balanced and with zero global feedback.

Key Features

• Completely new Bellini Anniversary design – engineered by Airtech laboratories.
• Inductive-capacitive power supply filtering – minimizes power supply disturbances.
• Se.Ge.STA amplifier stage – designed for lower noise and natural sound reproduction.
• Fully balanced architecture – differential input and output stages.
• Zero global feedback – preserves signal purity throughout the amplification stage.
• Four-layer PCB layout – carefully designed to separate analogue, digital, input and output signal paths.
• Premium components – Airtech capacitors, 7N OCC pure copper internal wiring and gold-plated connectors.
• Solid aluminium remote control – supplied together with the preamplifier.

Technical Description

Inductive power supply to reduce any kind of noise from the AC network to the line stage, zero global feedback from input to output, fully differential circuit (differential input and differential output) with discrete components dual-mono configuration, digital volume control without operational amplifiers and with four selectable volume scales, relay input switches to minimize non-linearities, oversized military resistors to minimize thermal distortion, audiograde capacitors made under Airtech specification, microcontroller management, internal wiring and Airtech power supply cable, gold-plated input and output connectors.
