Using surround back channel processing

• Default setting: SBch ON

You can have the receiver automatically use 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES), or you can choose to always use

6.1or 7.1 decoding (for example, with 5.1 encoded

material). With 5.1 encoded sources, a surround back channel will be generated, but the material may sound better in the 5.1 format for which it was originally encoded (in which case, you can simply switch surround back channel processing off).

The table below indicates when you will hear the surround back channel when playing various kinds of sources (=Sound plays through surround back speaker(s)).

•Press SBch (SBch PROCESSING) repeatedly to cycle the surround back channel options.

Each press cycles through the options as follows:

•SBch ON – 6.1 or 7.1 decoding is always used (for example, a surround back channel will be generated for 5.1 encoded material)

•SBch AUTO – Automatically switches to 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES)

•SBch OFF – Maximum 5.1 playback

Using the Virtual Surround Back mode

When you’re not using surround back speakers, selecting this mode allows you to hear a virtual surround back channel through your surround speakers. You can choose to listen to sources with no surround back channel information, or if the material sounds better in the format (for example, 5.1) for which it was originally encoded, you can have the receiver only apply this effect

to 6.1 encoded sources like Dolby Digital EX or DTS-ES.1

The table indicates when you will hear the virtual surround back channel (=Virtual surround back channel is active).

•Press SBch (SBch PROCESSING) repeatedly to cycle the virtual surround back channel options.

Each press cycles through the options as follows:

•VirtualSB ON – Virtual Surround Back is always used (for example, on 5.1 encoded material)

•VirtualSB AUTO – Virtual Surround Back is automatically applied to 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES)

•VirtualSB OFF – Virtual Surround Back mode is switched off
