These settings can be used while listening to the radio or the 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 settings makes spoken words sound very clear. Select DRIVER to give the driver the best possible sound qualities. Select NORMAL to enhance the stereo effect. Select SPATIAL to make the listening space seem larger.
