Impedance Selector Switch - Yamaha RX-V592RDS Owner's Manual

OUTPUT terminals (for driving speakers with external amplifiers)
MAIN
MAIN OUTPUT terminals
These terminals are for main channel line output. There is no
connection to these terminals when you use the built-in
amplifier.
However, if you drive main 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.
* Output signals from the MAIN OUTPUT terminals only are
affected by the use of BASS, TREBLE, BALANCE controls
and BASS EXTENSION switch.
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.

IMPEDANCE SELECTOR switch

Be sure to switch this only when the power of this unit is turned
off.
Select the position whose requirements your speaker system
meets.
WARNING
Do not change the IMPEDANCE SELECTOR switch
setting while the power to this unit is on, otherwise this
unit may be damaged.

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.
SUBWOOFER OUTPUT terminal
This terminal is for connecting with the input terminal of an
amplifier for driving a subwoofer.
When the input signals to this unit are in normal 2-channel
stereo, this terminal outputs only frequencies below 150 Hz
from the main and center channels. When discrete signals are
input to this unit and are selected as the input source, this
terminal outputs signals from the subwoofer channel.
Note
Output level of signals from all of these terminals are adjusted
by the use of VOLUME control on the front panel or VOLUME
(MASTER 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.
If you use two center speakers, the impedance of
each speaker must be 4 or higher.
Main: If you use one pair of main speakers, the impedance
of each speaker must be 8 or higher.
If you use two pairs of main speakers, the impedance
of each speaker must be 16 or higher.
