You can connect both surround back and presence speakers to this unit, but they do not output sound simultaneously.
• The surround back speakers output the surround back channel included in Dolby Digital EX and DTS-ES software and only
operate when the Dolby Digital EX, DTS-ES or Dolby Pro Logic IIx decoder is turned on.
• The presence speakers output ambient effects created by the DSP sound fields. They do not output sound when other sound fields
are selected.
