when you turn the power on.

continues to output multi-channel signals with “MULTI CH” shown 
on the display window even if the surround mode is turned off during 
playback. On the other hand, the system outputs only the front left and 
front right channel signals with “LR ONLY” shown on the display 
window when you start playback with the surround mode having been 
set to “SURR OFF”.
