ADDING A SUBWOOFER
You may wish to add a subwoofer to reinforce the bass
frequencies.
This unit provides a line-level subwoofer output, which contains
only the frequencies under 200 Hz from the main and center
channels. Connect the LOW PASS jack to the INPUT jack of the
subwoofer amplifier, and connect the speaker terminals of the
subwoofer amplifier to the subwoofer.
With some subwoofers, including the Yamaha Active Servo
Processing Subwoofer System, the amplifier and subwoofer are in
the same unit.
