The DOLBY DIGITAL listening mode is recommended for
Dolby Digital sources recorded with Dolby Digital Surround
EX. This listening mode can also be used with 5.1-channel
Dolby Digital sources with mixed results.
• Listening mode name differs depending on the encoding
present in the input source, the EX DECODING parameter
setting and the speaker setup. The table on the next page
indicates the conditions in which Dolby Digital Surround EX
decoding is engaged.
• Decodes 5.1 discrete channels from 5.1-channel Dolby Digital

frequency range of 120Hz.
• When the DOLBY DIGITAL EX listening mode is activated,
matrix decoding derives a surround back channel from the
other surround channels.
