Be sure to get the Dolby Digital signal
To be sure that the Dolby Digital or other digital signal from your DVD player reaches your
receiver, connect its digital sound output to the digital sound input on your receiver. You must
use a coaxial cable, with RCA connectors on each end, or an optical (Toslink) cable that has
unique, “square” cable ends. See Figure 9. Be sure to connect the digital sound jacks; these
are in addition to the traditional analog connections that carry the Dolby Pro-Logic signal.
Many DVD players have a switch on the back which you must place in the digital position. If
you cannot find such a switch, there may be an on screen menu where you must select digital
audio.
You must also be sure to select Dolby Digital at your receiver’s front panel or remote control.
For example, when playing a movie on a DVD, you must select a video output, in this case
DVD, and an audio output, Dolby Digital. You may also have to set up the digital signal using
the receiver’s front panel or on-screen menu. Please consult your receiver owner’s manual for
specific details.
