LFE Attenuate
Some Dolby Digital and DTS audio sources include ultra-low bass tones. Set the LFE attenuator as necessary to prevent the ultra-low 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. 1 Press SETUP.
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 37). 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. 1 Carry out tone testing. Press TEST TONE.
