If your vehicle has the Bose radio, your audio system
allows you to choose from four different AUTO EQ
settings: talk, driver, normal and spatial. The AUTO EQ
settings can be used while listening to the radio, the
cassette tape player or CD player. Press the AUTO EQ
button to scroll through your choices. Select TALK
-
when listening to non musical material such as news,
talk shows, sports broadcasts and books on tape.
This setting makes spoken words sound very clear.
Select DRIVER to give the driver the best possible
sound qualities. Select NORMAL to enhance stereo
effect. Select SPATIAL to make the listening space
seem larger. When AUTO EQ NORMAL is displayed,
the system will provide the best overall Bose
performance. The radio keeps separate AUTO EQ
settings for each preset and source.
