INSTALLATION MANUAL
Silent retrofit system MOTUS
(Version 07/02/2018)
-Upright piano-
-Keyboard sensors installation.
Put the springs on the rear side of the two greys supports using the white springs supports, the insertion is
done by clockwise rotation. The rail is fixed to the plate with wood screws between 3x20 and 3x50 following
the chassis heights, these screws go through the springs to adjust the height. For chassis having very little
keyboard height like Kawai or Schimmel, make a chambering of 8 mm depth on the plate using an 8 mm
drill bit with stop ring, wherein the spring will reside. When the space under the keyboard is too high, add on
the set of wood shims to the location of the screws. Fit the four sensor circuits in order, P1 in the low and
then following P2 and P3 and P4 finally the small circuit in the treble.
The edge of sensors rail must be at around 5mm from key pins board as photo above.
Use 2 sharps near the ends of each circuit to ensure the best lateral centering, placing you at the vertical of
keyboard to have the best global centering place under all black keys.
O
blong holes are used for lateral
precise adjustment.

- Page 1 INSTALLATION MANUAL Silent retrofit system MOTUS (Version 07/02/2018) -Upright piano- -Keyboard sensors installation. Put the springs on the rear side of the two greys supports using the white springs supports, the insertion is done by clockwise rotation. The rail is fixed to the plate with wood screws between 3x20 and 3x50 following the chassis heights, these screws go through the springs to adjust the height.
- Page 2 Certain keyboard is not perfectly standard, good centering of 2 sharps end of each circuit is not possible, in this case, try to adopt the best lateral centering compromise without favoring a touch against another. Then slightly tighten the circuits of fixing screws to immobilize temporarily adjust the height so that the above sensors to be about 2mm below the black keys in the depressed position without compressing the front rail washer.
- Page 3 Glue the rubber band with contact neoprene glue. With the oval holes in the hinges, place the blocker next to the hammers. Adjust the hammers blocking point at 4 mm of strings, verify that this distance is constant over all notes, if it is not the case, placing wedges under the hinges to equalize the blocking point.
- Page 4 be at around 1 mm of the hammer shank to allow the maximum space to dampers stroke at the passage. If this distance is greater, reduce the stroke by adding a felt thickness above the center pedal. On some pianos, the first damper mediums may abut the blocker, in this case shorten the damper button screw, if this is not enough, you have to shorten the damper button itself Place the non-return lock washer on the axis of treble bracket to prevent lateral movement of the blocker.
- Page 5 Bring slowly into contact with no pressure on the front rail washer, release the key, the system stores the maximum measured value and FC displays this end of stroke position and the words MEMO as screen below. N 1. MEMO FC 203 Repeat this process on all the keys, it is not possible to store 2 times following the same key, if you want to re-store the same note, the nearby store before returning the key in question.
- Page 6 : 74 V: 34 M: 42^^: 30 F: 190 N:52 V:72 M:56 Vol:100 % N is the number of the note played, V is the velocity of depression of the key, M is the sound level Midi audible through headphones, calculated by the software based on the speed V, Vol is finally setting the individual volume of the note to reduce or increase, this is the value of M.
- Page 7 Reverb. Select the reverb level using the + or - key, press Menu again to confirm. Programming sounds. See on our web www.chavanne.com indications. Note: The headset provides standard is first price for a demonstration model or to take full advantage of audio realism, we recommend to use the headphone Seinheiser HD25, it perfectly isolates the mechanical noise blocker and sound quality is amazing.

Page 8: Grand Piano
-Grand piano- -Installation Keyboard sensors. The principle is identical to the upright piano, however, as the place for the springs is insufficient, adjusting height will be done using paper wedges and cardboard. We are developing a new rotary hammers shanks blocker staying inside the piano. Thank you contact us.
