If you play an acoustic piano and live in an apartment, you’ve probably thought about the silent system at some point. It lets you play with headphones at any hour without losing the real mechanism of a genuine piano.
At Jorquera Pianos we’ve been installing it for years on pianos of every range, from an entry-level upright to a Steinway grand, and in this guide we explain how it works, what options exist, and what to consider before installing it.
What Is a Piano’s Silent System?
The silent system is a device that turns an acoustic piano into a hybrid instrument: you can play it normally or activate silent mode to hear it only through headphones. It’s made up of three main parts: a bar that stops the hammers before they strike the strings, a board of optical sensors under the keyboard that registers every keystroke, and a control unit that generates the digital sound and manages headphones, USB, and MIDI.
When the system is off, the piano works exactly like any acoustic piano. When you turn it on, the bar blocks the hammers’ path a few millimetres before they reach the strings, so there’s no acoustic sound. The optical sensors detect the speed and intensity of each key and play back a pre-recorded piano sound through the headphones.
It’s important to understand one thing from the start: the sound you hear through the headphones isn’t the real sound of your piano, it’s a digital sample of a piano recorded beforehand. What you do keep is the touch, the weight, and the response of the acoustic keyboard, which is the part that truly sets a piano apart from a conventional digital keyboard.
How the Silent System Works Inside
The system combines a mechanical part and an electronic one, and both have to be perfectly calibrated for the result to be reliable.
The Bar That Blocks the Hammers
The muting bar is a piece of felt fitted into the mechanism, between the hammers and the strings. When you turn on silent mode, this bar gets in the hammer’s path and stops it just before impact. The rest of the mechanism, keys, pivots, escapement levers, rollers, keeps working exactly as it does in acoustic mode. That’s what makes the feel of playing almost identical, even though no sound comes from the strings.
The Optical Sensors and the MIDI Signal
Underneath the keys is a board with optical sensors that register each key’s movement: when it’s pressed, at what speed, and for how long it’s held. That information becomes a MIDI signal, which the control unit processes through a sound engine built from real acoustic piano samples. The result is sent to the headphones in real time.
This same MIDI signal is what lets you connect the piano to a computer, tablet, or phone to record, use sheet-music apps, or change the instrument you’re hearing, some systems include harpsichord, strings, or even other sampled pianos.
To understand how the silent system fits within the rest of the mechanism, Piano Parts Explained: How Your Instrument Works breaks down every component individually.
Can It Be Installed on Any Piano?
Generally speaking, yes. The silent system is compatible with the vast majority of acoustic pianos, both upright and grand, regardless of brand. But there’s an important difference between the two types of instrument.
On an upright piano, the mechanism is simpler and installation tends to be more straightforward. On a grand piano, however, the double escapement mechanism comes into play, exclusive to this type of piano, which lets you repeat a note quickly without fully releasing the key. This mechanism requires much more precise calibration when installing the silent system, because a poorly done adjustment can affect precisely that function, one of the biggest advantages a grand piano has over an upright.
That’s why, if you have or are planning to buy a grand piano and want to add the silent system, who installs it matters as much as which system you choose. A technician who installs it occasionally is not the same as a specialised workshop that works daily with high-end grand mechanisms.
If you’d like to dig deeper into the differences between the two formats, you’ll find more context in What’s the Difference Between a Grand Piano and an Upright Piano?
Factory Silent System vs. Installed Afterwards: Which to Choose?
The difference isn’t just in the price, it’s also in how the system integrates with the piano’s original mechanism.
| Factory System | System Installed Afterwards | |
|---|---|---|
| Who installs it | The manufacturer’s own technicians, at the factory | A specialised technician, at a workshop or on-site |
| Fitting precision | The piano is designed with the system in mind from the start | Requires adapting a piano that wasn’t originally built with it |
| Warranty | Covered as part of the piano | Depends on the workshop’s terms |
| Compatibility | Only on pianos of that specific brand | Practically any brand |
| Cost | Included in the piano’s price difference | Additional cost, separate from the piano |
If you’re buying a new piano and know you’ll use the silent function often, it’s best to consider a model that already includes it from the factory, especially for grand pianos. If you already have an acoustic piano and want to add this feature, a well-installed third-party system, such as Genio or AdSilent, is a solid option, especially on upright pianos.
If you’re considering buying a second-hand piano with a silent system already installed, it’s worth having it checked over carefully before deciding. In How to Buy a Second-Hand Piano Without Surprises we cover what to check before closing the purchase.
Does the Silent System Affect the Piano’s Touch?
This is probably the most repeated question among people considering a silent system, and the answers out there don’t always agree. Most guides and shops claim that, if the system is properly installed, the touch and the keyboard’s response aren’t noticeably affected. In pianist forums, on the other hand, some users describe the installation as involving a readjustment of the mechanism’s escapement regulation, which in theory could slightly alter note repetition.
Our honest recommendation is this: any work on a piano’s mechanism, however minor, should be done by a technician with proven experience on your specific model. A correct adjustment on an upright has nothing to do with a correct adjustment on a high-end grand piano. Before installing any silent system, always ask for a test on your own piano after installation, not just on a showroom model.
Kawai Anytime, Genio, AdSilent: A Few Systems on the Market
Not all silent systems are the same, and they’re not installed the same way. These are the ones we come across most often in our day-to-day workshop life.
| System | Type | Fits On | Strong Point |
|---|---|---|---|
| Kawai Anytime (ATX) | Proprietary, factory-fitted | Kawai pianos, upright and grand | Sensors on the hammers rather than under the keys, greater precision according to the manufacturer |
| Genio Premium | Third-party | Practically any brand | The most widespread on the market, good value for money |
| AdSilent | Third-party | Any brand, including high-end ones like Petrof | An alternative to Genio for a more discreet integration |
Proprietary factory systems are only available on pianos of that specific brand. Third-party systems, on the other hand, let you add the silent function to a piano you already own, whatever its brand or age, as long as the mechanism is in good condition.
How Much Does It Cost to Install a Silent System?
The price depends mainly on two factors: whether the piano is upright or grand, and whether the system is factory-fitted or installed afterwards. As a general rule, a grand piano requires a more complete, and therefore more expensive, system than an upright, and factory systems tend to cost more than third-party ones.
We don’t include specific figures here because the final price depends on your piano’s exact model and the system chosen. If you’d like a figure tailored to your case, at Jorquera Pianos we provide a no-obligation quote after assessing the instrument.
Request a QuoteDoes the Silent System Void Your Piano’s Warranty?
If the piano comes with the silent system factory-installed, the piano’s warranty also covers the system, since it’s part of the instrument from the moment it’s manufactured. If instead you install a silent system on a piano you already own, or one you buy without it, this installation usually doesn’t affect the piano’s own warranty, as long as it’s carried out by a qualified technician and properly documented.
Even so, it’s worth clarifying in writing with whoever installs the system exactly what the warranty covers. The warranty on the silent system itself, the electronic components, is usually shorter than the piano’s, and it’s worth knowing in advance what happens if the system fails within that period.

Silent System Maintenance: What You Should Know
Unlike the acoustic piano, which needs regular tuning, the silent system is an electronic component and doesn’t require regular maintenance. Your piano can be out of tune in acoustic mode and the silent system will keep sounding exactly the same, because the sound you hear through headphones is a digital sample and doesn’t depend on the real strings.
What is worth keeping an eye on is the hardware itself: like any electronic device, the system can develop faults over time, sensors, connectors, the control unit. If you notice strange noises when using silent mode, buzzing, or a key losing responsiveness, it’s time to have it checked by a technician, just as you would with any electronic equipment starting to fail.
And remember that the piano itself, its acoustic side, still needs its usual care. In The Importance of Tuning Your Piano Regularly we explain why you shouldn’t neglect that side even if you use the silent system daily.
Silent Systems on High-End Pianos
One common debate is whether it’s worth installing a silent system on a high-end piano, such as a Steinway, a Petrof, or a Bösendorfer. The short answer is yes, as long as the installation is carried out by a workshop with genuine experience with that type of mechanism.
The reason is simple: the more complex and refined a piano’s mechanism, the more room there is for error when working on it. On a high-end grand piano, with double escapement and millimetre-precise regulation, a generic installation can stand out far more than on an entry-level upright. That’s why at Jorquera Pianos we apply the same level of care to installing a silent system as to the rest of our workshop work, whether on a €4,000 piano or a €300,000 one: the idea is for the system to add a new function without taking anything away from what makes that instrument special.
This also applies to high-end second-hand pianos that come in for a check-up: before installing any silent system, it’s worth doing a full assessment of the mechanism’s condition, not just checking whether it’s compatible on paper.
