I Subwoofer connection
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.
Low bass signals distributed from the main, center and/or
rear channels are directed to this jack. (The cut-off
frequency of this jack is 90 Hz.) The LFE (low-frequency
effect) signals generated when Dolby Digital or DTS is
decoded are also directed if they are assigned to this jack.
Notes
• Adjust the subwoofer volume according to the operation
instructions for the subwoofer. (Fine adjustment is possible using
this unit's output level control of the effect speakers.)
• Depending on the settings of "1 SPEAKER SET", "LFE LEVEL
(5 DOLBY D. SET)" and "6 DTS SET" in the SET MENU, some
signals may not be output from the SUBWOOFER jack.
