Yamaha RX-V650 Manual Do Utilizador

■

If you want to increase the power output to the speakers, 
or want to use another amplifier, connect an external 
amplifier to the PRE OUT jacks as follows.

• When audio pin plugs are connected to the PRE OUT jacks for 

output to an external amplifier, do not make connections to the 
corresponding SPEAKERS terminals. Set the volume of the 
amplifier connected to this unit to the maximum.

• The signals output through the FRONT PRE OUT and 

CENTER PRE OUT jacks are affected by the TONE 
CONTROL settings.

• If SPEAKERS A is turned off and SP B is set to ZONE B (see 

page 62), signals will only be output from the FRONT PRE 
OUT jacks.

Connect a subwoofer with built-in amplifier, such as the 
YAMAHA Active Servo Processing Subwoofer System, 
to this jack.

• Each PRE OUT jack outputs the same channel signals as the 

corresponding speaker terminals.

• Adjust the volume level of the subwoofer with the control on 

the subwoofer. It is also possible to adjust the volume level 
using the remote control (see “Manually adjusting speaker 
levels” on page 52).

• Some signals may not be output from the SUB WOOFER PRE 

OUT jack depending on the SPEAKER SET (see page 56) and 
LFE/BASS OUT (see page 57) settings.
