Yamaha RX-V492RDS Manuale Utente

12

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.

This terminal is for connecting with the input terminal of an
amplifier for driving a subwoofer. 
This terminal outputs only frequencies below 150 Hz (200 Hz
for General model only) 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.

Be sure to switch this only when the power of this unit is turned
off. 
Select the position whose requirements your speaker system
meets.
