Yamaha RX-V2400 Manuale Utente

■

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 
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.

• Signals will only be output from the FRONT PRE OUT jacks 

when SPEAKER A is turned off with ZONE B selected for SP 
B SET (see page 57).

Front channel line output jacks.

Surround channel line output jacks.

Center channel line output jack.

Surround back or presence channel line output 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 signal as the 

corresponding speaker terminals. However, when both surround 
back and presence speakers are connected to this unit, the 
channel of the signals output from SURROUND BACK / 
PRESENCE PRE OUT jacks may not correspond to the 
location of the speakers connected through SURROUND 
BACK / PRESENCE PRE OUT jacks.

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

the subwoofer. It is also possible to adjust the volume level by 
using the remote control of this unit (see “Manually adjusting 
speaker levels” on page 45.).

• Some signals may not be output from the SUBWOOFER jack 

depending on the SPEAKER SET (see page 49) and LFE 
LEVEL (see page 51) settings.
