06 Listening to your system Enjoying various types of playback using the listening modes Using this receiver, you can listen to any source in surround sound. However, the options available will depend on your speaker setup and the type of source you're listening to. To play with surround sound, check "Standard surround sound" or "Using the Advanced surround effects" below and select the desired mode. To play with the optimum mode for the input signal, see "Auto playback" or "Using Stream Direct". (The sound is played in stereo when 2-channel signals are input, in surround when multi-channel signals are input.) Important ! The listening modes and many features described in this section may not be available depending on the cur- rent source, settings and status of the receiver. Auto playback There are many ways to listen back to sources using this receiver, but the simplest, most direct listening option is the Auto Surround feature. The receiver automatically detects what kind of source you're playing and selects multichannel or stereo playback as necessary. % While listening to a source, press AUTO (AUTO SURR/ALC/STREAM DIRECT) for auto playback of a source. AUTO SURROUND shows briefly in the display before showing the decoding or playback format. Check the digital format indicators in the front panel display to see how the source is being processed. ! If the source is Dolby Digital, DTS, or Dolby Surround encoded, the proper decoding format will automatically be selected and shows in the display. ! When listening to the BT AUDIO input, the SOUND RETRIEVER AIR feature is selected automatically. ALC - In the Auto level control (ALC) mode, this receiver equalizes playback sound levels. Also, the low and high frequency sounds, dialogs, surround effects, etc., that are difficult to hear when the volume is low are adjusted to be optimal for the volume level. This mode is particularly optimum when listening at night. Note When ALC is selected, the effect level can be adjusted using the EFFECT parameter in Setting the Audio options on page 73.
