CONNECTIONS
■ 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.

WARNING
Do not change the IMPEDANCE SELECTOR switch setting
while the power to this unit is on, otherwise this unit may be
damaged.
IF THIS UNIT FAILS TO TURN ON WHEN THE STANDBY/
ON SWITCH IS PRESSED:
The IMPEDANCE SELECTOR switch may not be set to either
end. If so, set the switch to either end when this unit is in the
standby mode.
■ 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.
