Adjusting the Listening
Position
One of the conditions for reproduction of
more natural music is to "clearly define the
sound image positioning (listen to music at
the center of the sound field)".
The position selector function
appropriately adjusts the delay time and
level of the sound from each speaker
according to the seat position(s) and the
number of people in the car and allows to
recall this setting with a single button
operation. This makes the listener(s)
possible to obtain natural acoustic
property regardless of the seat positions.
