AUDIO ANALOGUE
Anniversary Line designed by AIRTECH
Bellini Anniversary

The Bellini Anniversary preamplifier, the new born of Audio Analogue, designed in the Airtech laboratories, is part of the Anniversary line, re-proposing another of the historical products of Audio Analogue. The only thing in common between this new model and the previous versions of Bellini remains the name, while the project and the technical solutions used are completely new. Starting from the excellent base constituted by the preamp section of the Maestro Anniversary integrated amplifier, the novelties with respect to the latter are however multiple. The first is the power supply stage that has been completely redesigned using an inductive-capacitive filtering to minimize mains disturbs. The filter inductance has been designed and manufactured specifically for this device. The amplification stage, called SeGeSTA (Single Gain Stage Transconductance Amplifier), has been designed to make the preamplifier even quieter while keeping the structure completely balanced and without global feedback. The circuit has 4 layers and the positioning of the components has been carefully thought out to avoid crossings between the input and output signals and above all between the digital control signals and the sensitive analog signals. The use of audiograde components and internal wiring made with 7N OCC pure copper cables complete the picture. Bellini Anniversary is available in silver and black finish and it is supplied with solid aluminium remote control and Airtech power cord.
Donizetti Anniversary

The power amplifier Donizetti Anniversary, the new born of Audio Analogue, designed in the Airtech laboratories, is part of the Anniversary line, re-proposing another of the historical products of Audio Analogue. The only thing in common between this new model and previous versions of Donizetti remains the name, while the project and the technical solutions used are completely new. It is a high power stereo power amp: with its 250W@8Ω that doubles halving the impedance is able to perfectly drive any loudspeaker. The amplifier has a complete dual-mono configuration starting from the two 1200VA toroidal transformers specifically designed for low dispersed flow. Uses our SeGeSTA (Single Gain Stage Transconductance Amplifier) configuration followed by a group of four transistors to provide all the necessary current without affecting the gain stage performance. The amplifier does not use global feedback. The 4-layer printed circuit has been designed so that the input signal never crosses the output signal and that the sensitive amplification stages are as far from the power transformers as possible. All components are of the highest level, starting from military standard resistors to continue with the capacitors on Airtech specification up to the wiring made of 7N OCC copper and to the pure copper and gold-plated connectors. Donizetti Anniversary is available in silver and black. Donizetti Anniversary can also be used in mono configuration, achieving even more extreme performance, just think of the output power that reaches over 1000W on 8Ohm impedance.
Maestro Anniversary

Maestro Anniversary was born in AIRTECH's laboratories following to the experience gained with the development of Puccini Anniversary. The basic scheme is very similar, but with one important difference: the amplification chain is fully balanced from the input to the power stage which becomes unbalanced to connect to the speakers. This took to a doubling of amplifier stages and attenuation. Also in the Maestro Anniversary all stages are without global feedback. The feedback is not even used on preamp stage(as in Puccini). The output power was increased to 150W on 8Ω with the consequent adjustment of all the driver and power stages that now use four pairs of transistors per channel. The basic configuration remains inverted cascode that is comparable to a single gain stage followed by the output buffer. The stability of the working point is maintained through a DC Servo that begins to work only at frequencies below a few tenths of Hertz (then totally out of the audio band). Thanks to a so refined circuitry, along with the selection of components of the highest level (military standard resistors, polypropylene audiograde capacitors custom made for AIRTECH, internal wiring with 7N OCC copper and pure copper output connectors) helped to create an amplifier that has the honor of being the heir of the glorious Maestro Integrated and therefore fully joins the Anniversary line celebrating at the same time, the first 20 years of Audio Analogue, but also 15 years by the introduction of AUDIO ANALOGUE's first product to bear the Maestro name. The new Maestro Anniversary is a unique amplifier, its remarkable power that always doubles with decreasing impedance and its extraordinary driving skills, are accompanied by a unique musicality and refinement not common for so “muscular” amps. Unfortunately it is not easy to express in words all its peculiarities and therefore we invite you to listen to it as soon as possible and can only confirm that now more than ever MUSICA MAESTRO!!!
Puccini Anniversary

20 years of Audio Analogue, 20 years of Puccini, the two things go hand in hand ... the Puccini, the first amplifier and the first Audio Analogue product and absolute milestone of high fidelity audio. The dream was to create the best Puccini ever, a product that would mark a turning point in the history of Audio Analogue and show the way for what will be the products of the future, created with the intention of giving top sound performances, but also technically very advanced. This is certainly a tall order and to make it possible we have seen the consolidation of an idea born in the Airtech laboratories: development of an integrated amplifier without global feedback, being this way less sensible to the kind of load driven, without the tendence to oscillate, without high frequency resonance peaks, with no saturation in the input stages and with completely balanced circuitry.
