and below. The initial setting is "BOTH".
SW: Select the "SW" (subwoofer) setting if you use a subwoofer. The LFE signals are directed to the subwoofer.
MAIN: Select the "MAIN" setting if you do not use a subwoofer. The LFE signals are directed to the main speakers.
BOTH: Select the "BOTH" setting if you use a subwoofer and you want to mix the main channel low frequency sound signals with the
LFE signals.
Caution
• The low frequency signals of 90 Hz and below from all main, center, rear, and rear center channels are directed to the LFE channel when
you select the small speaker setting in items 1A, 1B, 1C, and 1D.
I 1F FRONT EFCT SP (front effect speaker mode)
This unit uses front effect speakers to localize the virtual sound sources of the sound field programs. If you do not use front effect speakers,
you can direct the front effect signals to the main speakers.
The OSD shows small or no front effect speakers depending on how you set this item. The initial setting is "YES".
YES: Select the "YES" setting if you use front effect speakers.
NONE: Select the "NONE" setting if you do not use front effect speakers. The front effect signals are mixed with the main channels.
I 1G MAIN LEVEL
Change this setting if you cannot match the sound volume of the front effect, rear, center, and rear center speakers with the main speakers
because of the unusually high efficiency performance of the main speakers. The initial setting is "Normal".
Normal: Select the "Normal" setting if you can match the volume of your effect speakers with the volume of your main speakers using the
"TEST DOLBY SUR.".
–10dB: Select the "–10dB" setting if you cannot match the volume of your effect speakers with the volume of your main speakers using
