I Connecting a front subwoofer
Connect the signal input jack on your subwoofer to the PREOUT/
MAIN IN SUBWOOFER MONO jack.
By connecting two subwoofers to the SUBWOOFER SPLIT jacks,
this unit can reproduce subtle directional changes in the low
frequency sounds.
When you use two subwoofers, connect both of them to the
SUBWOOFER SPLIT jacks using pin plugs.
I 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 36).
Caution
• Adjust the speaker volume for the subwoofer with the controls on
the subwoofers, not on this unit.
I Impedance selector switch
Select the position whose requirements your speaker system meets.
(Upper position)
Front effect: The impedance of each speaker must be 6Ω or
higher.
Rear:
The impedance of each speaker must be 4Ω or
higher.
Rear Center: The impedance of the speaker must be 4Ω or higher.
Center:
The impedance of the speaker must be 4Ω or higher.
Main:
If you use one pair of main speakers, the impedance
of each speaker must be 4Ω or higher. If you use
two pairs of main speakers, the impedance of each
speaker must be 8Ω or higher.
(Lower position)
Front effect: The impedance of each speaker must be 8Ω or
higher.
Rear:
The impedance of each speaker must be 8Ω or
higher.
Rear Center: The impedance of the speaker must be 8Ω or higher.
Center:
The impedance of the speaker must be 8Ω or higher.
Main:
If you use one pair of main speakers, the impedance
of each speaker must be 8Ω or higher. If you use
two pairs of main speakers, the impedance of each
