The DSP and STEREO modes are designed to be used with music sources but some DSP modes are also suited for film soundtracks. Again, try different settings with various soundtracks to see which you like. You must choose one of the three cinema modes or the DSP mode in order to get surround sound. In STEREO mode only the front two speakers, and sometimes the subwoofer (if you have one), are used. STANDARD modes STANDARD mode decodes Dolby Digital, DTS and Dolby Pro Logic sources (see page 83 for more detailed information), and plays them without any further processing. You can think of this as the basic surround sound mode of the receiver. Using STANDARD 7. 1 you can enjoy surround sound from additional surround back speaker(s). You will only be able to access STANDARD 7. 1 if you have hooked up SURROUND BACK speaker(s). For more detailed information see p. 19, 32-33. STANDARD This mode decodes Dolby Digital, DTS or Dolby Pro Logic sources with no additional effects. If you don't have SURROUND BACK speaker(s) switched on (see p. 32-33) this is the only STANDARD mode you will be able to select on the receiver. STANDARD 7. 1 STANDARD 7. 1 is a Pioneer technology that generates realistic 7 channel surround sound without destroying the original sound staging. You will only be able to access this mode if you have set the SURROUND BACK speakers in the SPEAKER SETUP procedure (see p. 32-33).
