Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the instrument or other property. These precautions include, but are not limited to, the following:

Power supply/AC power adaptor		Location

•When removing the electric plug from the instrument or an outlet, always hold the plug itself and not the cord.

•Unplug the AC power adaptor when not using the instrument, or during electrical storms.

•Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can result in lower sound quality, or possibly cause overheating in the outlet.

•Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal components.

•Do not use the instrument in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Otherwise, the instrument, TV, or radio may generate noise.

•Do not place the instrument in an unstable position where it might accidentally fall over.

•Before moving the instrument, remove all connected adaptor and other cables.

•When setting up the product, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Even when the power switch is turned off, electricity is still flowing to the product at the minimum level. When you are not using the product for a long time, make sure to unplug the power cord from the wall AC outlet.

•Use only the stand specified for the instrument. When attaching the stand or rack, use the provided screws only. Failure to do so could cause damage to the internal components or result in the instrument falling over.

Introduction

Thank you for purchasing the Yamaha Digital Piano!

We recommend that you read this manual carefully so that you can fully take advantage of the advanced and convenient functions.

We also recommend that you keep this manual in a safe and handy place for future reference.

Main Features

Graded Hammer Effect Keyboard

Thanks to our experience as the world’s leading manufacturer of acoustic pianos, we’ve developed a keyboard with action that’s virtually indistinguishable from the real thing. Just as on a traditional acoustic piano, the keys of the lower notes have a heavier touch, while the higher ones are more responsive to lighter playing. The keyboard’s sensitivity can even be adjusted to match your playing style.

AWM Dynamic Stereo Sampling

This digital piano offers a rich and versatile range of sounds, which are created using Yamaha’s proprietary sampling tone-generation system, “AWM Dynamic Stereo Sampling.”

AWM (Advanced Wave Memory) is a sampling system that creates sounds close to those of an acoustic instrument by digitally recording the sounds of an instrument and applying high-quality digital filtering technology to the recorded audio samples.

The sound waveform created by an acoustic piano differs depending on the player’s strength of touch, from pianissimo to fortissimo.

AWM Dynamic Stereo Sampling can create extremely dynamic nuances by recording samples at various playing strengths. The greater the number of samples used, the greater the resulting expressiveness of the instrument.

The piano voice “Grand Piano 1” features a totally new sample recorded from a full-size concert grand piano. Each note in the sample has been adjusted meticulously so that the digital piano will play only the very best piano sounds. The piano voices are well-separated sounds featuring a fast attack and a satisfying response.

The “Grand Piano 1” voice features multiple wave samples for different velocities (Dynamic Sampling). That is, different samples are used depending on how fast or strong the player strikes the keys. Therefore, this voice expresses detailed dynamics and sounds much closer to those of a true acoustic piano.

The instrument creates a rich, luxurious sound using “Sustain Sampling,” which is a sample of the soundboard and the resonance of the strings when the damper pedal is pressed. The instrument also features “Key-off Sampling,” which is a sample of the very delicate noises that are caused when keys are released.
