  • Page 10 [Work Procedure]　－ Adjusting the stop rail height per section － In the GP, the distance between the keybed and the string undersurfaces may vary depending on the areas of the piano. In the GP-ATX, it is possible to adjust the stop rail height per section to follow the variation of this distance, and make sure that the muting happens at the 4 mm point of let-off.

  • Page 11: Ｃ】 Adjusting The Sensor Height

    [Preparation] 　・Phillips Screwdriver No.2 　・Flat screwdriver No.2 The height of the sensor is one of the elements that has a direct influence on the emission of the electronic sound and the muting position. For instances, if the sensor is located at an extremely high position, the position of emitting sound may be higher than the position where the hammer stops by the stop rail.

  • Page 17: Ｈ】 Adjusting Volume Inconsistency

    【H】 Adjusting Volume Inconsistency Perform this operation if the sound volume balance is obviously inconsistent when each key is pressed down with the same strength. This operation must be performed also after replacing the sound source board. ※ Usually the electronic sound volume is set as flat with the balance between the keys. However, the key touches sometimes are not even because generally smoothness and friction are slightly different per each key on the piano keyboard and action.
