Hookups
Connecting a Rear Subwoofer
By using both Front and Rear Subwoofers, the CINEMA-DSP sound field
programs can produce realistic movie effects with powerful, dynamic sound. To
take advantage of this dynamic sound, be sure to set the 1C. REAR L/R SP item
in the SET MENU to "LARGE" (see page 37), and connect your Rear speakers
and Subwoofer as shown below.
Connect the right + input terminal on your Subwoofer to the REAR

R + terminal, and the right – input terminal on your Subwoofer to
the REAR R – terminal with speaker cords.
Connect the left + input terminal on your Subwoofer to the REAR

L + terminal, and the left – input terminal on your Subwoofer to the
REAR L – terminal with speaker cords.
Connect your Rear speakers to the output terminals on the Rear

Be sure to connect the Rear speakers to the Subwoofer with the correct
polarity.
Note:
• Adjust the speaker volume for the Subwoofer with the controls on the Subwoofers,
not on the DSP-AX1.
