Grand Piano P 210 Pasat

Rim
Petrof 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 rim is CNC worked.

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 longterm tuning stability and action regulation as well as sound board crown stability, which is a prerequisite 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 posts are CNC worked.

The last treble post is made from special plastificated and compressed beech wood compouding hardness of the wooden frame in the zone of 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 sound 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 dynamically.

Iron plate
Czech producer. Gray cast iron, hand worked finish, 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. CNC working ensures high accuracy of string scaling. Bright colour shade supports noble look of piano.

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 maintanance.

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 10 mm in the center, tapered to 7.7 mm along the perimeter, asymmetric crown.
Made from European mountain spruce. Special longterm moistrure conditioning and care during the whole production process.

Ribs
Petrof original.
Made from European mountain spruce.
Assymetric shaped.
Arc shaped laminated beech cross rib, CNC worked.

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 bored.

The genuine ebony wood used in the treble bridge cup minimalizes dumping of the highest tones. The maple and ebony cap 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.

Scale
Agraffes, front and rear tuned duplexes. Single hitch pinning in the whole range.

Duplexes enrich the tone colour of the grand piano Pasat. Single hitch pinning increases tuning stability.

Tuning pins
Steel, nickeled, stain resistant.

Strings
Steel wire Mapes USA, Röslau Germany.
Copper winding Degen Germany.
Longest string 1493 mm.
Bass strings Petrof original.

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.

Action
Petrof original action.
Wippen rail aluminium.
Hammer rail aluminium.
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 aluminium 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.
Key bed is additionally reinforced by bulky solid wood rail from below.
Key bed is CNC worked.
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.
Middle pedal has function of prolongement.

The construction, materials and function of P 210 Pasat´s pedals are comparable in quality with the highest class grand pianos´ pedal mechanisms.
