SUBWOOFER jack

When using a subwoofer with built-in amplifier, including the YAMAHA Active Servo Processing Subwoofer System,
connect the input jack of the subwoofer system to this jack. This unit will direct low bass signals distributed from the
main, center and/or rear channels to this jack in accordance with your SPEAKER SET selections. The LFE (low-
frequency effect) signals generated when Dolby Digital or DTS is decoded are also directed to this jack in accordance
with your SPEAKER SET selections.
Notes
• The cut-off frequency of the SUBWOOFER jack is 90 Hz.
• If you do not use a subwoofer, allocate the signals to the main left and right speakers by changing the setting of "SOUND 1
SPEAKER SET" item "1E BASS" on the set menu to MAIN.
• Use the control on the subwoofer to adjust its volume level. You can also adjust the volume level by using this unit's remote control
(see "SETTING THE SPEAKER LEVELS" on page 50).
