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 only frequencies below 200 Hz from the
main and center channels.
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.
(Upper position)
Rear: The impedance of each speaker must be 6 or
higher.
Center: If you use one center speaker, the impedance of the
speaker must be 6 or higher.
If you use two center speakers, the impedance of
each speaker must be 3 or higher.
Main: If you use one pair of main speakers, the impedance
of each speaker must be 4 or higher.
If you use two pairs of main speakers, the impedance
of each speaker must be 8 or higher.
(Lower position)
Rear: The impedance of each speaker must be 8 or
higher.
Center: If you use one center speaker, the impedance of the
speaker must be 8 or higher.
