that is not assigned to any of the digital input jacks.
Some laser discs have only analog audio signals. If your laser disc
is this type, use the ANALOG setting.
The receiver accepts Dolby Digital or PCM (32 kHz/44 kHz/48
kHz) digital signals only. For other formats of digital signals, use
the ANALOG setting.

strong, the overload indicator (a dot above the 2nd character position)
lights. If this happens, press
ATT

nal and prevent the distortion. ATT lights on the display.
