You must follow the instructions in the DVD
manual to select the Dolby Digital soundtrack.
This is sometimes labeled “5.1” or “AC-3”.

playing in one of the digital inputs, the Theater
Grand Processor will separate the two
channels into stereo mode. This allows you to
manually select any of the DSP modes, or
Dolby Pro Logic.
Note: The Dolby Digital Locked Light only
comes on for Dolby Digital multichannel sources,
not for Dolby Digital 2-channel sources.

The 5.1 Surround modes
Dolby Digital and DTS are “5.1” surround
systems with five main channels: left, center,
right, left surround and right surround. Each
channel can play the full frequency range and
is independent of the other channels. The “.1”
denotes the subwoofer channel which plays
the low frequency effects (LFE), also indepen-
dent of the other channels.
With the Bass Management of the
Theater Grand Processor, the subwoofer can
play the bass from all the other channels in
addition to its own LFE channel.
The Theater Grand Processor will auto-
matically detect and lock on to these digital
signals.
