Connections
Connecting Your Laser Disc Player (with AC-3 RF Output), continued
Do not plug in the receiver to AC power until you have
connected all your devices.
You must purchase an RF Demodulator (DEM-9991D) if
you plan to operate a player with a Dolby Digital (AC-3) RF
output with this receiver.
These instructions describe how to connect a laser disc player
with an AC-3 RF output. If your laser disc player does not
have an AC-3 RF output, see “Connecting Your Laser Disc
Player (without AC-3 RF Output)” on page 28. Please refer
to your laser disc player’s instructions for more detail about
its connection jacks and capabilities.
The instructions in this section show one of several pos-
sible variations on connecting your laser disc player. For
further assistance on optional configurations, contact the
store where you purchased your receiver.

the laser disc player’s digital jack to the appropriate
DIGITAL INPUT jack on the demodulator as shown to
