(See page 8. ) The following DAP modes are provided with this receiver: LIVE CLUB: DANCE CLUB: HALL: PAVILION: Reproduces the spatial feeling of a live music club with a low ceiling. Reproduces the spatial feeling of an exhibition hall. I DSP (Digital Signal Processor) modes DAP (Digital Acoustic Processor) modes DAP modes have been designed to create important acoustic surround elements. The sound heard in a live club, dance club, hall or pavilion consists of direct sound and indirect sound--early reflections and reflections from behind. On the other hand, indirect sounds are delayed by the distances of the ceiling and walls (see the diagram below). These indirect sounds are important elements of the acoustic surround effects. The DAP mode can create these important elements, and give you a real "being there" feeling. These DAP modes can be used to add acoustic surround effects while reproducing 2 channel stereo software, either analogue or Linear PCM digital signal, and can give you a real "being there" feeling. When one of the DAP modes is selected, the DSP indicator lights up on the display. All Channel Stereo This mode can reproduce a larger stereo sound field using all the connected (and activated) speakers. All Channel Stereo can be used when the front and surround speakers are connected to this receiver without respect to the center speaker connection. If the center speaker is connected and activated, the same phase of the front left and right signals are mixed and output through the center speaker. Make sure that you have set the speaker information correctly (see pages 15 to 18). 6 Turn MULTI JOG to adjust the item selected in step 5, then press SET. Your setting is stored.
