Surround sound settings

Using the Virtual Surround Back mode
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

Adjusting the channel levels using the test tone
If you prefer, you can set the channel levels using a test tone as a reference, rather than playing a source (see Channel level setting on page 30). A test tone is played through each speaker in turn, allowing you to adjust the level as it plays. You can also adjust the channel levels for surround sound using test tone.

2 Adjust the channel level of a tune while it is playing. The aim is to adjust the levels so that you hear the test tone at the same volume from each speaker. You can adjust the level of each channel by ±10 dB. � You can adjust the overall volume of test tone output using the VOL +/� buttons (this does not affect the channel level settings). � Because of the ultra low frequencies the subwoofer produces, it may sound quieter than it really is. We suggest adjusting the subwoofer level while listening to a source. See the method described in Channel level setting on page 30. 3

Press to exit.

LFE Attenuate
Some Dolby Digital and DTS audio sources include ultralow bass tones. Set the LFE attenuator as necessary to prevent the ultralow bass tones from distorting the sound from the speakers. The LFE is not limited when set to 0dB, which is the recommended value. When set to -5dB, -10dB, -15dB or -20dB, the LFE is limited by the respective degree. When Off is selected, no sound is output from the LFE channel.
