06 Listening to your system • AUTO SURROUND - See Auto playback on page 61. • ALC - Listening in Auto level control mode (page 61). • DIRECT - Sources are heard according to the settings made in the Surround Setup (speaker setting, channel level, speaker distance, acoustic calibration EQ, and X-curve), as well as with dual mono, the input attenuator, and any sound delay and hi-bit/hi-sampling (SC-25 only) settings. You will hear sources according to the number of channels in the signal. • PURE DIRECT - Analog sources are heard without any digital processing.1 No sound is output from the Speaker B in this mode. • OPTIMUM SURR - Listening in Optimum Surround mode (page 61). 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 6.1 or 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). • With a 7.1-channel surround system, audio signals that have undergone matrix decoding processing through surround back channel processing to which the Up Mix function is added are output from the surround back speakers.

Each press cycles through the options as follows: • SBch ON - Matrix decoding processing for generating the surround back component from the surround component is turned on. • SBch AUTO - Matrix decoding processing for generating the surround back component from the surround component is switched automatically. Matrix decoding processing is only performed when surround back channel signals are detected in the input signals. • SBch OFF - Matrix decoding processing for generating the surround back component from the surround component is turned off. Using the Virtual Surround Back mode • Default setting: OFF 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.2 • Press SBch 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 Note 1 There are cases where a brief noise is heard before playback of sources other than PCM. Please select AUTO SURROUND or DIRECT if this is a problem. 2 • You can't use the Virtual Surround Back mode when the headphones are connected to this receiver or when any of the THX, stereo, Front Stage Surround Advance or Stream Direct mode is selected. • You can only use the Virtual Surround Back mode if the surround speakers are on and the SB setting is set to NO or if Front Bi-Amp, Speaker B or ZONE 2 is selected at Surr Back System. • The Virtual Surround Back mode cannot be applied to sources that do not have surround channel information. 66 en
