Yamaha RX-V861 User Manual

■ Connecting an external amplifier
This unit has more than enough power for any home use. However, if you want to add more power to the speaker output 
or if you want to use another amplifier, connect an external amplifier to the PRE OUT jacks. Each PRE OUT jack outputs 
the same channel signals as the corresponding SPEAKERS terminals.

• When you make connections to the PRE OUT jacks, do not make connections to the SPEAKERS terminals.
• The signals output at the FRONT PRE OUT jacks are affected by the TONE CONTROL settings (see page 48).
• Adjust the volume level of the subwoofer with the control on the subwoofer (see page 48).
• Some signals may not be output at the SUBWOOFER PRE OUT jack depending on the settings for “SPEAKER SET” (see page 72) 

and “LFE/BASS OUT” (see page 72).

1 FRONT PRE OUT jacks
Front channel output jacks.

2 SURROUND PRE OUT jacks
Surround channel output jacks.

3 SUR.BACK PRE OUT jacks
Surround back channel output jacks. When you only 
connect one external amplifier for the surround back 
channel, connect it to the SINGLE jack.

• When “BI-AMP” is set to “ON”, this unit outputs the front 

channel audio signals at the SUR.BACK PRE OUT jacks.

• The audio signals output at the SUR.BACK PRE OUT jacks 

differ depending on the “EXTRA SP ASSIGN” setting (see 
page 72).

4 SUBWOOFER PRE OUT jack
Connect a subwoofer with a built-in amplifier.

5 CENTER PRE OUT jack
Center channel output jack.

■ Connecting a multi-format player or an external decoder
This unit is equipped with 6 additional input jacks (left and right FRONT, CENTER, left and right SURROUND and 
SUBWOOFER) for discrete multi-channel input from a multi-format player, external decoder, sound processor or pre-
amplifier.
If you set “INPUT CH” to “8CH” in “MULTI CH SET” (see page 80), you can use the input jacks assigned as “FRONT” 
in “MULTI CH SET” (see page 80) together with the MULTI CH INPUT jacks to input 8-channel signals.
Connect the output jacks on your multi-format player or external decoder to the MULTI CH INPUT jacks. Be sure to 
match the left and right outputs to the left and right input jacks for the front and surround channels.

• When you select the component connected to the MULTI CH INPUT jacks as the input source (see page 38), this unit automatically 

turns off the digital sound field processor, and you cannot select sound field programs.

• This unit does not redirect signals input at the MULTI CH INPUT jacks to accommodate for missing speakers. We recommend that 

you connect at least a 5.1-channel speaker system before using this feature.
