SURROUND MODES
A surround mode is signal processing that enhances original source material.
There are two main types of surround modes – those that apply to
stereo
source material and those that pertain to
5.1-channel
source material.
Factory defaults for Surround Modes are set so that all of your surround speakers are used with any type of
source material. To change these defaults, see Mode Presets in section 7.4.5.
Stereo Source Material:
This includes both analog stereo and digital stereo (stereo PCM or Dolby Digital 2.0) source material. Various
surround modes can be applied to provide up to 7.1 channels of output. These are described in depth
throughout this section. Each Source memorizes its own Mode setting, so you can, for example, set VCR to
‘AnthemLogic-Cinema’, and then set CD to ‘AnthemLogic-Music’ – when you change Source, the respective
Modes are remembered.
Surround modes are not available for inputs set to Anlg-Dir (see section 7.4.5).
Regarding analog VCR input: With analog, there is no way for any processor to detect Dolby Surround
encoded material. Dolby Pro Logic must therefore be turned on manually by selecting it in the Mode options.
5.1- and 6.1-Channel Source Material:
The AVM 20 detects the digital format that you select in the DVD menu (Dolby Digital or DTS) and
automatically engages decoding for the selected format. Alternatively, you can select the format on-the-fly
after pressing the player’s remote control ‘Audio’ button. Note that only one format is sent over the digital
connection at a time – the AVM 20 displays and decodes the one that is selected in the player.
As soon as the AVM 20’s display shows the format, you can select additional processing, described
throughout this section – there is usually plenty of time to do so when the film studio’s logos are played at
the beginning of a movie. Your selections are memorized by format and by Source as well.
Make sure your DVD player setup menu is set to leave Dolby Digital and DTS unchanged (“Bitstream”),
otherwise it will have 2.0-channel PCM at the digital output instead of the 5.1 channels on the disc.
