! If you’re not using a subwoofer, change the front speaker setting (see Speaker Setting on page 74 ) to
LARGE.
! You can use the additional amplifier on the surround back channel pre-outs for a single speaker as
well. In this case plug the amplifier into the left (SURROUND BACK L (Single)) terminal only.
! The sound from the surround back terminals will depend on how you have configured the Speaker
system setting on page 76 .
! If you have two subwoofers, the second subwoofer can be connected to the SUBWOOFER 2
terminal. Connecting two subwoofers increases the bass sound to achieve more powerful sound
reproduction. In this case, the same sound is output from the two subwoofers.
! To hear sound only from the pre-outs, switch the speaker system to OFF, or simply disconnect any
speakers that are connected directly to the receiver.

puts (depending on whether your player supports surround back channels). Make sure that the
player is set to output multichannel analog audio.
