Using Digital Signal Processing (DSP) Available only with the premium Bose® audio system, this feature is used to provide a choice of five different listening experiences: DSP normal, talk, spacious, rear seat, and driver seat. DSP can be used while listening to the radio or the CD player. The radio keeps separate DSP settings for each band, preset, and source. To select a DSP choice, perform the following steps: 1. Press the TUNE/SEL knob to enter the main menu. 2. Turn the TUNE/SEL knob until one of the five settings appears on the display. 3. Press the TUNE/SEL knob to select a DSP setting. 4. Press the CLR button to exit the display. To return to the original display, repeatedly press the CLR button or wait for the display to time out. DSP NORMAL: This setting provides the best overall audio performance for all passengers. DSP NORMAL will not appear on the display when in this mode. TALK: This setting should be used when listening to non-musical material such as news, talk shows, sports broadcasts, and books on tape. Talk makes spoken words sound very clear. SPACIOUS: This setting is used to make the listening space seem larger. REAR SEAT: This setting adjusts the audio to give the rear seat passenger(s) the best possible sound quality. Sound quality for the front seat passengers may be different when this setting is used. DRIVER SEAT: This setting adjusts the audio to give the driver the best possible sound quality. Sound quality for the front and rear seat passenger(s) may be different when this setting is used. 268
