Chapter 3 Mute Rail Installation
1.
Key points for Installation
It is the most important to install the mute rail at the right position to stop the hammer shanks
just before touching the strings for mute play.
If the mute rail installation is not perfect, you can hear the real piano sound during mute on,
and the action working is not so harmonious during acoustic mute off play, and it disturbs the
basic piano performance.
Notably, securing the damper’s working space is very important for acoustic play.
Pay attention to Kawai new models, especially the damper’s free moving in middle-end section.
There are tailored mute rails for several popular models and you don’t need to cut the mute
rails. Just inform your piano model name when placing order.
Y121 (for Yamaha U1, U2
,
Old U2 should be cut a little shorter)
Y131 (for Yamaha U3)
K125 (for Kawai 124
~
127cm, Since BL)
K132 (for Kawai 132cm, BL61, 71 US50 etc, Since BL)
STANDARD BAR (No Cutting, Need aluminum rail cutting. Old Kawai KU need to be cut from
the standard type)
Kawai type middle-end part is already cut for the damper block screw to escape from the
interference with mute rail.
