What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

ALIANTE ONE PF


With the ONE PF (Pininfarina) the glamorous car's designer enters Hi-Fi world. Its style is recognizable through the design, the harmonious forms and lines, that immediately evocate the wonderful cars worldwide admired.We are extremely proud of ONE (Pininfarina) manufacture; it's a real jewel built with MDF panels from 35 to 60 mm thick, worked with high precision CNC machines and assembled thanks to low tolerance joints. But it is not only a shapely object because nothing of its aesthetic design is fortuitous; rounded edges to reduce diffractions, tilted front baffle for improved phase coherence, the area next to the tweeter opportunely shaped to improve dispersion and reduce the baffle effect. The finishing process is extremely complex: starts with different steps of insulators making the wood structure absolutly inhert in order to recive the metalized colours. The metalized paints are obviously exclusive and very expensive; they are applyed in a pressure cabin in several layers, finished with a brightly transparent and dried for 72 hours. Only now, after the last polishing, the different parts of the manufacture are ready for assembling. To guarantee a perfect sound, the metallic grids are large-meshed, so they can not be pressed but are individually modelled by an expert panel beater. Clearly the ONE (Pininfarina) project is very difficult to build and consequently they are produced in a short series; exclusive objects only for connoisseurs.SEAS and SCANSPEAK, two of the best european specialists, produce the drive units following our strict specifications. The woofer features a new generation diaphragm with an innovative polymer ; the unit shows an unusually shaped phase plug coming from a long period of reserch and development. The device optimizes midrange performances avoiding colours, focusing image and improving heat dissipation from the pole piece. The plug is built by turning from fine solid copper, a very expensive but functional material, mostly useful for dissipation of the voice coil. The soft dome tweeter D2905 comes from SCANSPEAK, with a new silk fabric diaphragm, hand made and manually coated in different steps to achieve a perfect damping without increasing mass and thus preserving transient dynamic reproduction. The high quality drive units allow the use of a (6dB/ott) 1st order crossover without compensation network, wich is the best for really audiophile applications. Than the circuit typologies and the implementation techniques don’t forget the precious experiences of the past, years of realization known for their wonderful sound. You can find high quality in the passive components too; SOLO CFAC inductors use a thin OFC copper ribbon; AUDIOCAP PPFF film and foil capacitors and the special non inductive resistor are produced following our strict directions and needs. The cables come from a high performance wire for fast data networks. Input terminals admit all type of connections and the complete mass separation allows both bi-wiring (highly recommended) and bi-amping.
