1〕Information; 2〕Basic Structure; Ａ】 Operation Of Mute Mechanism - Kawai ANYTIME X2 GP Service Manual

〔1〕INFORMATION
This guide describes the basic structure of the Grand Piano ANYTIME X2, and provides instructions on
how to perform adjustments and troubleshooting.
Please refer to this guide for maintenance services.
〔2〕BASIC STRUCTURE
ANYTIME X2 is an hybrid instrument that incorporates an acoustic piano and a digital piano, therefore
it has a unique structure which is different from both acoustic and digital pianos. Also different from the
traditional Anytime series, it adopts a new mechanism which captures the playing information from the
hammer's movement.
【Switching the Modes】
To switch from Standard Play Mode to Silent Mode, use the mute lever located on the high tone keys
side under the keybed as shown in Figure 1.
Then, turn the volume knob of controller to the right to turn on the digital sound generator.
【Internal Behavior】
1. When the mute switching lever is pulled, the wire inside the piano is pulled (Figure 2) and the drive
lever (P) linked with the wire rotates.
2. When the dDrive lever (P) rotates, the lower part of the drive lever (A) attached to the action (shown
in Figure 2) is pushed and pivots on the rod.
3. When the drive lever (A) rotates, the connected stop rail arm turns and goes down, as shown in
Figure 3. In this way, the hammer shank is stopped just before striking the string.
＊ In GP-ATX2 , adjusting the wire tension will not have any effect on the height of the stop rail.
Since an unnecessary adjustment of the wire tension will cause the following malfunctions, use the
proper screw for adjusting the the stop rail height as indicated in step 〔3〕
［Wire Tension］
・Too tense : When the mute lever is pulled, the drive lever (P) might miss the stopper.
・Too loose : In the Standard mode, the drive lever (P) might stand up too much and interfere the
lower part of drive lever (A).
＊ After exchanging the wire, adjust the wire tension following step 〔3〕 【F-7】 .
＊ If the drive lever (P) is not properly installed, it might cause the following malfunctions.
［DRIVE LEVER (P) - Install position］
・Too forward : It will make the adjustment difficult to perform as the stop rail goes down too much.
・Too backward : It will make the adjustment difficult to perform as the stop rail goes up too much.
＊ For exchanging the drive lever (P), first follow the instruction 〔3〕 【F】 , then adjust the stop rail height
as indicated in step 〔3〕 【B】 .
