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.

These are proprietary surround modes developed by Anthem that offer outstanding surround performance and can be applied to any 2-channel source material:

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.

7.1

CHANNEL OUTPUT

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.
