Practice Anytime, Without Disturbing Others
– Silent Unit Installation in Just Half a Day.

For those who want to practice at night but are concerned about disturbing others, want to focus on their practice, or want to enjoy various sounds on a real piano, the Silent Unit is highly recommended.

The Silent Unit is a device that suppresses the sound of the piano without affecting the touch of the acoustic piano.
If you're considering a Silent Unit, trust Musashi Gakki, which has extensive experience in installations.

What is a Silent Unit (Silent Mechanism)?

A Silent Unit is a device that surpresses the sound of an acoustic piano, while preserving the original touch of it. Instead, the sound is transmitted through headphones or speakers. It is like transforming your acoustic piano into an electronic piano.

An acoustic piano generates sound when the hammer strikes the strings in coordination with the keys. By installing the Silent Unit, the hammer's motion is stopped just before it strikes the strings. The movement of the keys is then detected by sensors, and the sampled sound is played through headphones or speakers. You can easily switch between the silent mode and the normal acoustic mode at any time.

If you want to practice at night, need a focused practice environment, or are concerned about sound leakage to others, we recommend installing a Silent Unit. The Silent Unit can be added to your existing piano. Additionally, installation can be done at your home, so there’s no need to move the piano.
For those considering a Silent Unit, consult Musashi Gakki, which has rich experience in installation.

Silent Unit Installation Process

Here is a simple explanation of the installation process for the silent unit.

① All the internal parts of the piano, such as the action and keys, are removed.
② Various parts, such as the sensors that detect touch and the hammer stop rail that suppresses the hammer movement during silent mode, are installed in their respective positions.
③ After all parts are installed, the piano action is adjusted for silent operation.
④ Initial settings and operation checks are completed, and the installation is finished.

The installation takes about 3 to 5 hours, depending on the model, and can be completed in about half a day.
Installation can also be done at your home.

A sensor rail with optical sensors is installed under the keys.
A hammer stop rail that suppresses the hammer movement is installed on the hammer side.
