Advantages of the construction and materials used in the grand piano PETROF 210 Pasat

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
