Traditional expert craftsmanship combined with Yamaha Smooth Release technology, the SILENT Piano™ SC2 type offers the crisp, direct tones and powerful sound. When the SILENT Piano™ function is activated, the hammers will no longer hit the strings and instead, a highly sophisticated sensor-technology captures all movements of the keys and sends them to the digital tone module. Play a real acoustic piano with headphones at any time, day or night without being disturbed or disturbing others.
