Yamaha RX-V661 User Manual

■ Speaker distance  C)SP DISTANCE
Use this feature to manually adjust the distance of each 
speaker and the delay applied to the respective channel. 
Ideally, each speaker should be the same distance from the 
main listening position. However, this is not possible in 
most home situations. Thus, a certain amount of delay 
must be applied to the sound from each speaker so that all 
sounds will arrive at the listening position at the same 
time.

  UNIT

Choices: meters (m), feet (ft)
Initial setting:
[U.S.A. and Canada models]: feet (ft) 
[Other models]: meters (m)
• Select “meters” to adjust speaker distances in meters.
• Select “feet” to adjust speaker distances in feet.

Speaker distances

• The available speaker channels differ depending on the setting 

of the speakers.

graphic equalizer screen.
