NOTE "Room Size" does not indicate the size of the room in which sources are played. ON : Set. OFF : Do not set. [Example] Playing Dolby Digital software (with EX flag) • When "AFDM" is set to "ON", the surround mode is automatically set to the DOLBY D + PLgx C mode. • To play in the DOLBY DIGITAL EX mode, set "AFDM" to "OFF" and "Surround Parameter" - "S.Back" to "MTRX ON". Some Dolby Digital EX sources do not include EX flags. If the playback mode does not switch automatically even when "AFDM" is set to "ON", set "Surround Parameter" - "S.Back" to "MTRX ON" or "PLgx CINEMA". Setting items S.Back Sets the method of generating of the surround back channel. Setting details nn For 2-channel sources ON : The surround back channel is used. OFF : No signal is played from the surround back channels. nn For Multi-channel sources Set the decoding method for the surround back channel. DSCRT ON : Play the surround back signals included in the 7.1-channel source. MTRX ON : Generate and play the surround back signals from the surround channel signals. ES MTRXz1 : Generate and play the surround back signals from the surround channel signals of the DTS source. ES DSCRTz2 : Play the surround back signals included in the 6.1-channel DTS source. PLgx CINEMAz3 : Generate and play the surround back signals by decoding the signals in the Dolby Pro Logic gx Cinema mode. PLgx MUSIC : Generate and play the surround back signals by decoding the signals in the Dolby Pro Logic gx Music mode.
