On/Off Surround Button
This button switches between surround sound and 2 channel stereo.
IMPORTANT NOTE: The Dolby Digital (AC-3) mode can be selected
only when either LD, DSS Digital, or DVD inputs are selected. If you
have selected a digital source with a Dolby Digital soundtrack and you
cannot get the “3/2.1” indicator on the display (see page 23), the most
likely causes are:
1. The DVD player is not set to send out a 5.1 channel Dolby Digital
signal. In this case check the DVD player’s operation manual.
2. The 5.1 soundtrack has not been selected on the DVD disc. In this
case press the disc menu button on your DVD player to access the DVD
disc’s menu, and select Dolby Digital 5.1 on the disc’s set-up menu.
Consult your DVD player’s operation manual for more information.
3. The DVD disc does not have a 5.1 surround soundtrack. This is
especially true of pre-1985 movies.
