CENTER OUTPUT terminal
This terminal is for center channel line output. There is no
connection to this terminal when you use the built-in amplifier.
However, if you drive a center speaker with an external power
amplifier, connect the input terminal of the external amplifier to
this terminal.
SUBWOOFER OUTPUT terminal
This terminal is for connecting with the input terminal of an
amplifier for driving a subwoofer.
This terminal outputs low frequencies from the main and center
channels. (The cut-off frequency of signals output from this
terminal is 150 Hz.)
When 6 channel discrete signals are input to this unit and are
selected as the input source, this terminal outputs signals from
the subwoofer channel.
REAR (SURROUND) OUTPUT terminals
These terminals are for rear channel line output. There is no
connection to these terminals when you use the built-in
amplifier.
However, if you drive rear speakers with an external stereo
power amplifier, connect the input terminals of the external
amplifier (MAIN IN or AUX terminals of a power amplifier or an
integrated amplifier) to these terminals.
Note
Output level of signals from these terminals are adjusted
by the use of VOLUME control on the front panel or VOLUME
keys on the remote control transmitter.
OUTPUT terminals (for driving speakers with external amplifiers)
Be sure to switch this only when the power to this unit is not on.
Select the position whose requirements your speaker system
meets. (Upper position)
Rear: The impedance of each speaker must be 6
Ω
or
higher.
Center: If you use one center speaker, the impedance of the
speaker must be 6
Ω
or higher.
If you use two center speakers, the impedance of
each speaker must be 3
Ω
or higher.
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)
Rear: The impedance of each speaker must be 8
Ω
or
higher.
Center: If you use one center speaker, the impedance of the
speaker must be 8
Ω
or higher.
If you use two center speakers, the impedance of
each speaker must be 4
Ω
or higher.
Main: If you use one pair of main speakers, the impedance
of each speaker must be 8
Ω
or higher.
If you use two pairs of main speakers, the impedance
of each speaker must be 16
Ω
or higher.

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 closely. If so, set the switch to either end
closely.
