Adjusting the Speakers
DSP (Digital Signal Processing): The DSP
feature is used to provide a choice of four different
listening experiences. DSP can be used while
listening to the audio system or the CD player. The
audio system can store separate DSP settings
for each source and preset station, except
WX, which is always set to TALK.
To save DSP settings for your preset stations, use
the SOUND menu or touch DSP from the preset
station menu to access the DSP menu. See
"Sound Menu" listed previously in this section for
more information.
Touch DSP to change the following options:
ON/OFF: Touch ON/OFF to turn DSP on and off.
DRIVER SEAT: Touch this button to adjust
the audio to give the driver the best possible sound
quality.
TALK: TALK makes spoken words sound very
clear. Touch this button when listening to
non-musical material such as news, talk shows,
and sports broadcasts.
SPACIOUS: Touch this button to make the
listening space seem larger.
SOUND: Touch SOUND to access the Sound
menu. See "Sound Menu" listed previously in this
section for more information.
