Preparations
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.
1
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.
2
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.
3
Connect your Rear speakers to the output terminals on the Rear
Subwoofer.
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.
■
Impedance Selector switch
Select the position whose requirements your speaker system meets.
(Upper position)

Ω
or higher.
Rear Center:
The impedance of the speaker must be 4
Ω
or higher.
Center:
The impedance of the speaker must be 4
Ω

Main:
If you use one pair of main speakers, the impedance of each
speaker must be 4
Ω
or higher.
If you use two pairs of main speakers, the impedance of each
speaker must be 8
Ω
or higher.
(Lower position)
