4.8 SURROUND MODES
A surround mode is signal processing that enhances original source material.
Surround modes fall into two main categories – those that apply to stereo
source material and those that apply to multichannel source material.
Factory defaults for Surround Modes are set so that all of your surround speakers
are used with any type of source material except 1.0-channel input. To change
these defaults, see Mode Presets in section 3.5.
Stereo Source Material:
This includes analog stereo, digital PCM stereo, and Dolby Digital 2.0 source material. Surround modes can
be applied to provide up to 7.1 channels of output. They are described later in 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 3.5).
Regarding analog VCR input: With analog, there is no way for a processor to detect Dolby Surround encoded
material. Dolby Pro Logic must be turned on manually by selecting it in the Mode options.
5.1- and 6.1-Channel Source Material:
The AVM 50 detects the digital format that you select on each DVD and automatically engages decoding for
the selected format.
As soon as the AVM 50’s display shows the format, you can select additional processing, described
throughout this section. Your selections are memorized by format and by Source as well.
Why isn’t my AVM 50 detecting Dolby Digital 5.1 or DTS?
The connection can carry only one bit stream at a time, and the processor plays exactly what it gets.
Make sur
e your DVD player’s setup menu is set to leave Dolby Digital and DTS unchanged (“Bitstream”),
otherwise output will always be 2.0-channel PCM! You must also select the soundtrack that you want to
hear from each disc’s menu, or after the movie starts by pressing AUDIO on the player’s remote control.
