Starting Up Using headphones - [PHONES] jacks Connect a pair of headphones to the [PHONES] jacks. Since this instrument is equipped with two [PHONES] jacks, you can connect two pairs of headphones. Standard stereo phone plug CAUTION Do not use the headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. Reproducing the natural sensation of sound distance (even when using headphones) -Binaural Sampling and Stereophonic Optimizer This instrument features two advanced technologies that allow you to enjoy exceptionally realistic, natural sound, even though listening on headphones.  Binaural Sampling ("CFX Grand" Voice only) Binaural Sampling is a method that uses two special microphones set at the ear position of a performer and records the sound from a piano as it would actually be heard. Listening to the sound with this effect through headphones gives the impression of being immersed in the sound, as if it was actually emanating from the piano. Moreover, you can enjoy the sound naturally for a long time without ear fatigue. When the "CFX Grand" Voice is selected, connecting the headphones automatically enables the binaural sampling sound. Sampling A technology which records the sounds of an acoustic instrument and then stores them to the tone generator to be played based on information received from the keyboard.  Stereophonic Optimizer (VRM Voices other than "CFX Grand") Stereophonic Optimizer is an effect which reproduces the natural sound distance, like with the sound of Binaural Sampling, even though you are listening to it on headphones. When one of the VRM Voices other than "CFX Grand" is selected, connecting the headphones automatically enables the Stereophonic Optimizer. To see which Voices are VRM Voices, refer to the Data List on the website. What is VRM? On an actual acoustic piano, if you press the damper pedal and play a key, not only does the string of the pressed key vibrate, it also causes other strings and the soundboard to vibrate, each influencing the rest and creating a rich and brilliant resonance that sustains and spreads. The VRM (Virtual Resonance Modeling) technology featured in this instrument reproduces the complicated interaction of both string and soundboard resonance faithfully using a virtual musical instrument (physical modeling), and makes the sound more like a real acoustic piano. Since instantaneous resonance is made at the moment according to the state of the keyboard or pedal, you can vary the sound expressively by changing the timing of your pressing the keys, and the timing and depth of your pressing the pedal.
