These listening modes are designed to decode and playback 5.1 discrete channels from 5.1-channel Dolby Digital sources. The five main channels are full frequency. The .1 channel, often referred to as LFE information, has a limited frequency range of 120Hz.

The mode name differs depending on the encoding present in the input source, the EX DECODING parameter setting, and the speaker setup.

The Dolby DIGITAL EX listening mode is recommended for Dolby Digital sources recorded with Dolby Digital Surround EX encoding. This listening mode can also be used with other types of 5.1-channel Dolby Digital sources with mixed results. The table at the bottom of the page shows the conditions for the behavior of the Dolby Digital EX mode when activated.

The Dolby DIGITAL EX listening mode is available when both the side and rear speakers are present and Dolby Digital Surround EX decoding is activated. Matrix decoding is then applied to derive a surround back channel from the other surround channels.

•Dolby Digital Surround EX decoding is activated when the EX DECODING parameter is set to ON or AUTO and a flagged

5.1-channel Dolby Digital source recorded with Dolby Digital Surround EX encoding is detected.

•Dolby Digital Surround EX decoding is not activated when the EX DECODING parameter is set to OFF or AUTO and a non-flagged 5.1-channel Dolby Digital source recorded with or without Dolby Digital Surround EX encoding is detected.

Note:

The MC-12 cannot detect Dolby Digital Surround EX encoding in non-flagged 5.1-channel Dolby Digital input sources because they do not include information in the input signal that identifies Dolby Digital Surround EX encoding.

The Dolby DIGITAL listening mode is available when both the side and rear speakers are present and Dolby Digital Surround EX decoding is not activated.
