you must switch the input signal for digital or analog.
Select the device desired, then press SIGNAL SELECT ( RECEIVER followed by
SIG SELECT on the remote control). Each time you press the button the
input mode is switched between ANALOG and DIGITAL as shown on the
display. When the Dolby Digital signal is input, AC-3 appears on the
display.
Notes:
• SIGNAL SELECT does not function for any analog device or device
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.
Using ATT During analog operation, if the receiver receives signals that are too
strong, the overload indicator (a dot above the 2nd character position)
lights. If this happens, press
ATT on the remote control to lower the sig-
nal and prevent the distortion. ATT lights on the display.
