Note on a subwoofer connection:
You may wish to add a subwoofer to reinforce low frequencies
or to output low bass sound from the subwoofer channel when
reproducing discrete signals.
When using a subwoofer, connect the SUBWOOFER terminal
of this unit to the INPUT terminal 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. Such a subwoofer needs only the
connection between the SUBWOOFER terminal of this unit
and the INPUT terminal of the subwoofer.
(Refer to page 23 for details about the SUBWOOFER
terminal.)
