Yamaha RX-V2500 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, it is not necessary to use the 
corresponding SPEAKERS terminals. Set the volume of the 
external amplifier connected to this unit to the maximum.

• The signal 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 Multi Zone: Speaker B is set 

to “Zone B” (see page 66), 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.

Surround back or presence channel line output jacks. If 
you only connect one external amplifier for the surround 
back channel, connect it to the left (L) jack.

5

Center channel line output jack.

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

corresponding speaker terminals. However, when both surround 
back and presence speakers are setup in this unit, the signals 
output from SURROUND BACK/PRESENCE PRE OUT jacks 
may not correspond to the correct speakers.

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

the subwoofer.

• Some signals may not be output from the SUBWOOFER PRE 

OUT jack depending on the Speaker Set settings (see page 61).
