Advantages of the construction and materials used in the Master Grand Piano Petrof 210 Pasat
RimPetrof original. Inner rim – laminated beech, birch construction, 13 lamels. Outer rim – laminated construction from birch plywood. Total thickness of the rim 8.4 cm. The great thickness of the outer rim is one of many advantages of Petrof's grand pianos. It gives them strength, solidity and stability. Pasat's inner wooden frame ensures high and long term tuning stability and action regulation as well as sound board crown stability, which is a presumption for perfect performance.
Frame posts
4 Spruce posts + 1 treble post made from special plastificated and compressed beech wood called Lignamon. Connection – fish-tail + beech dowels. The last treble post is made from special plastificated and compressed beech wood compounding hardness of the wooden frame in the high frequencies. This causes less damping of the treble tones. A total of 5 frame posts provide high contour stability of the frame, stability of tuning and regulation. The treble post made of Lignamon wood enriches the grand piano with the bright long high tones.
Legs
Petrof original. Solid beech core, solid alder outer lining, Gabon counter veneer, outer decorative thin veneer. The robust construction of the legs ensures a high stability of the instrument when played.
Iron plate
Czech producer. Gray cast iron, hand worked, numerically exact drilled, lacquered. The iron plate, which is of a vivid light gold tint, perfects the modern design of the instrument. It is possible to harmonize the piano design with the design of its surroundings and to produce this grand piano with silver metal parts.
Iron plate support
Steel adjustable bolt between cross block of wooden frame and iron frame. The steel adjustable bolt increases form stability of the iron plate and consequently the Pasat´s tuning stability.
Hardware fittings
Petrof original. Solid brass, polished, lacquered. P 210 Pasat´s hinges and fittings are easily compared in quality with the highest class models of our competitors. Hardware fittings are corrosion resistant, therefore they do not require any maintenance.
Pinblock
Special beech plywood type Multiplex, original veneer thickness 2 mm compressed to the density 800 - 850kg/m3 (= 6 veneer layers/cm), high moisture resistant glue. The pinblock has a high resistance against atmospheric changes (e.g. humidity). It provides equal torque of tuning pins, which results in particularly high stability of tuning.
Soundboard
Petrof original. Diaphragmatic tapered around the whole perimeter. Thickness 9.5 mm in the center, tapered to 7.5 mm along the perimeter, asymmetric crown. Made from European mountain spruce. Special long term moisture conditioning and care during the whole production process.
Ribs
Petrof original. Ends hand fitted, asymmetric shaped, made from European mountain spruce. Shaped laminated beech cross rib. A new and original asymmetric crown and asymmetric tapering of the sound board and its ribs create optimal conditions for sound board resonation. This fact contributes to generating the typical tone of this grand piano.
Bridges
Petrof original. Treble – solid beech, maple cap, genuine ebony descant cap. Bass – solid beech, maple cap, lightened by holes. Bridges graphite coated, hand notched and bored. The genuine ebony wood used in the treble bridge cup minimizes dumping of the highest tones. The ebony cup enables better transmission of the treble tones onto the sound board. Pasat´s ebony bridge cup creates significantly bright and long sound of the high tones.
Duplex Scale
Agraffes, front and rear tuned duplexes. Single hitch pinning. Duplexes enriches the tone colour of the grand piano Pasat. Single hitch pinning increases tuning stability.
Strings & Tuning pins
Steel wire Mapes USA, Röslau Germany. Copper Degen Germany. Longest string 1493 mm. Bass strings Petrof original. Steel, nickeled, stain resistance. Petrof produce strings using the highest quality string wire.
Hammer heads
Abel Germany, walnut or hornbeam mouldings. Hornbeam hammer shanks. Abel premium under felt and top felt. Hammer heads Abel, which are fitted in this instrument, are some of the best worldwide. They enable the player to get a great variety of tones.
Dampers
Petrof, hornbeam heads. Felt Laoureux France. The felt, manufactured by French company Laoureux, is a guarantee of the highest quality proved by generations.
Magnetic Accelerated Action (MAA). Wippen rail aluminum. Hammer rail aluminum. Hornbeam action parts. The PETROF action is quick, with good repetition, it enables the grand piano Pasat to be played confidently, even technically demanding passages, and to have full control of creating tones. Specifically profiled aluminum action rails are very stable also in changing humidity.
Keys
Petrof original. European spruce, white and black acrylic tops – Polyplex Sweden. Individually balanced keys. Grand piano P 210 Pasat has keys of European origin, each key is individually balanced. The quality is proven by more than 140 years of production tradition.
Key bed
Petrof original. Spruce sandwich board, beech veneered. Solid beech insert in lyre and legs zone. Thickness 47 mm. Robust key bed is another component which ensures regulation stability of Pasat´s action as well as stability of the whole instrument while being played dynamically.
Pedals
3 pedals, solid brass. The construction, materials and function of P 210 Pasat´s pedals are comparable in quality with the highest class grand pianos´ pedal mechanisms.
