Reproducing a Natural Sound Distance Sensation (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 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
(page 53) other than "CFX Grand" is selected, connecting the headphones automatically enables the
Stereophonic Optimizer.
When headphones are connected, the VRM Voices (page 53) automatically change to the sound of Binaural
Sampling or the sound enhanced with the Stereophonic Optimizer, by the default settings. However, when
headphones are connected, these functions also affect the sound from the external speaker connected to the AUX
OUT jacks or the sound for Audio recording (page 75), and may result in unusual or unnatural sound. If this
happens, turn this function off.
You can turn this function on or off on the display called up via [Menu] → [Utility] → [Speaker/Connectivity]. For
details, refer to the Reference Manual on the website (page 9).
Using the Headphone Hanger
A headphone hanger is included in the instrument package so that you can hang the headphones on the
instrument. Install the headphone hanger by following the instructions on page 116, 119 or 122.
NOTICE
Do not hang anything other than the headphones on the hanger. Otherwise, the instrument or the hanger may be
damaged.
