Yamaha P-45B Digital Piano with 88 Hammer-Action Keys, Built-in Speakers, 64-Note Polyphony, and Black Finish

The Yamaha P-45B Digital Piano combines authentic acoustic piano feel and sound in a sleek, compact black design suitable for both children and adults. Featuring 88 hammer-action keys with adjustable touch sensitivity, built-in stereo speakers, and 64-note polyphony, this instrument delivers a realistic playing experience for daily practice and performance.

Advantages

The graded hammer-action keyboard offers a heavier touch in the lower registers and a lighter touch in the upper registers, closely mimicking the mechanical response of an acoustic piano. Matte finish black keys provide a secure and comfortable grip during extended sessions. Advanced sound sampling technology recreates natural acoustic resonance and reverberation, while the lightweight and slim chassis allows for effortless placement and transport in various living or performance spaces.

Suitable for

• Basic music production and MIDI controller use via the integrated USB port
• Small live performances and rehearsals requiring a portable instrument

What to consider before purchase

• Ensure you have adequate space, keeping in mind the 1326 mm width and 295 mm depth of the instrument.
• Verify whether you need to purchase a compatible keyboard stand, bench, or sustain pedal separately, as a tripod is not included.
• Check the availability of a nearby electrical outlet or appropriate DC power source for operation.

Usage recommendations: To maintain the condition of your digital piano, keep it away from direct sunlight, excessive moisture, and dust. Clean the exterior surfaces with a soft, dry cloth and avoid using liquid cleaners or abrasive materials on the keys and chassis.
