Yamaha R-S700BL Manual De Usuario

Removing the jumper pins from the PRE OUT/MAIN IN 
jacks enables this unit to operate separately as a control 
amplifier or a power amplifier. These jacks are used to 
connect a signal-processing system such as a graphic 
equalizer or a surround-sound processor to this unit. If an 
external unit is connected to these jacks, the VOLUME 
control of this unit can be used to adjust the overall sound 
output level.
To connect an external unit, first remove the jumper pins 
from the PRE OUT/MAIN IN jacks and then connect the 
input jacks of that external unit to the PRE OUT jacks or 
its output jacks to the MAIN IN jacks. For details, refer to 
the owner’s manual included with the external unit to be 
connected.

• If you do not use the COUPLER jacks, never remove the 

jumper pins from these jacks. If removed, no sound will be 
output from this unit.

• Before installing or removing the jumper pins, be sure to 

disconnect the power cable of the unit. Leaving the power cable 
connected could cause noise to be emitted from the speakers or 
damage the unit.

• When you use this unit as a power amplifier, connect the output 

jacks of the external control amplifier, etc. to the MAIN IN 
jacks of this unit. In this case, the controls of this unit will not 
function except the PHONES jack and the SPEAKERS A/B 
buttons. Use the controls on the external control amplifier to 
make volume adjustments, etc.

Plug the power cable into the AC IN on the rear panel of 
this unit (R-S700 only).
Plug the power cable into the AC wall outlet after all other 
connections are complete.
