Adsilent 2 aluminium mute rail vs steel mute rail

First of all, what is the mute rail in the adsilent 2 piano system?

The mute rail stops the hammer reaching the strings when silent mode is engaged. This keeps the piano “silent” and you use headphones intead.

Which mute rail do most pianos use?

Most installations use the standard aluminium mute rail. When fitted correctly, the piano action can be set to suit most pianists (let-off around 6–7 mm). This is also the quickest option to install.

When is the steel mute rail required?

The steel mute rail is used when there is insufficient space for the aluminium rail because the piano’s action is too small or the action design doesn’t leave enough room. The steel mute rail can also be chosen in order to minimise the required change of the let-off distance within the action for optimal touch control.

How does playing feel compare?

The steel rail is more rigid than aluminium, so the let-off distance usually changes less which means that less adjustments to the action are required. Both systems play perfectly well when carefully regulated but the steel rail is less of a compromise.

Does installation time differ?
Aluminium rails are faster to install. Steel rails take longer because components are cut and assembled for each piano and holes must be drilled into the action brackets to mount the custom supports.

What is the price difference?

The steel-rail kit costs £300 more to take into account the longer time needed during installation

Which option should we choose?
The standard aluminium rail is used on 99% of pianos. We would only recommend the steel version if the aluminium version doesn’t fit.
