Various surround modes produce 6.1 or 7.1 channels of output. If you are using a 5.1 system and
have Rears set to ‘None’ in the Speaker Configuration (section 3.2), no information is lost – it comes
out of the L/R Surround channels.
4.8.1 AnthemLogic
™
These are proprietary surround modes developed by Anthem that offer outstanding surround performance
and can be applied to any 2-channel source material:
AnthemLogic-Music
™
AnthemLogic-Music
™
enhances the stereo listening experience without detracting from the
stereo soundstage. Through extensive listening tests a very effective design was developed.
This is a minimalist design that uses no echo or reverberation effects which could negatively
affect the purity of the sound.
Depending on your speaker configuration, up to 6.1 channels of output are provided – L/R Fronts, L/R
Surrounds, L/R Rears and Subwoofer. AnthemLogic-Music
™
does not utilize the Center Channel, to ensure
that the purity of the stereo music soundstage will in no way be compromised when you’re sitting in the
‘sweet spot’ and listening to your favorite stereo recordings.
AnthemLogic-Music
™
is very effective in creating an expansive musical soundstage that psychoacoustically
helps to remove the barrier of the listening room itself, and it does so in a completely non-intrusive, natural
and very compelling way. This is the factory default 2-channel Mode for CD, TAPE, and FM • AM.
AnthemLogic-Cinema
™
AnthemLogic-Cinema
™
provides a large, enveloping and dynamic movie listening experience
that makes 2-channel movies sound more like what is experienced in a state-of-the art movie
theater. Again through extensive listening tests a very effective design was developed. This
is also a minimalist design that avoids the use of echo effects, which could otherwise
negatively affect the purity of the sound.
AnthemLogic-Cinema
™
uses the rear speakers to provide up to 7.1 channels of output, depending on your
speaker configuration.
AnthemLogic-Cinema
™
provides the missing link that lets you experience 7.1 channels of output for full
impact home theater sound, from any 2-channel stereo analog source such as VCR or TV, or any Dolby Digital
2-channel source, such as DVD or satellite. This is the factory default 2-channel Mode for all Sources except
CD, TAPE, and FM • AM.
4.8.2 DOLBY DIGITAL 2.0
Dolby Digital 2.0 soundtracks with surround encoding contain a flag that can be used to automatically
activate Pro Logic IIx Movie mode. The AVM 50 can be set to either use this flag or to override it.
To find out if the Dolby Digital 2.0 material being played has the surround flag, press MODE. If flagged, the
first line of the display says “DOLBY D 2.0 SUR AUTO” and if not flagged, it says “MODE FOR 2 CH INPUT”.
The Modes in the next section may be selected separately for flagged and unflagged stereo source material.
Single-channel soundtracks can be encoded in one of two ways – either using the Center channel, or
with the same signal into the Left/Right channels. The Mode changes to Mono if the soundtrack uses
only the Center channel – you can switch it to Mono-Academy or All Channel Mono afterwards.
