Description
Audio Analogue Bellini : 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.
The circuit has four layers and the placement of the
components has been carefully thought to avoid
intersections between the input and output signals and
between the digital control signals and the sensitive analog
signals too. The framework is completed by the use of
high-quality components and internal wiring made with 7N
OCC pure copper cables. Bellini Anniversary is available in
silver or black, it is equipped with a solid aluminum remote
control and Airtech power cord.
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.
