Crossover frequency setting mode
Setting speakers to “Small” in “SPEAKER setting mode” sends the respective channels’ bass frequencies to the sub
woofer (or “Large” speakers). This function lets you determine which frequencies will be sent to the sub woofer or
“Large” speakers.
• Initial setting is “100 Hz”.
• If all speakers (front, center, and surround) are set to “Large” in SPEAKER setting mode, crossover
frequency cannot be set. (

Press

speakers (100 Hz, 150 Hz or 200 Hz).
100 Hz
Sends bass frequencies below 100 Hz to the sub woofer (or Large
speakers).
150 Hz
Sends bass frequencies below 150 Hz to the sub woofer (or Large
speakers).
200 Hz
Sends bass frequencies below 200 Hz to the sub woofer (or Large
speakers). We recommend setting 200 Hz when only small speakers
are used.

LFE attenuator setting mode
Dolby Digital and DTS audio sources include ultra-low bass tones. Set the LFE attenuator as needed to prevent the
ultra-low bass tones from distorting the sound from the speakers.
