INTRODUCTION
HOWTO
INSTALL
THEC39

All movies produced by major film companies have Dolby Stereo soundtracks. When they
reach you via home video sources, the Dolby Surround encoding remains intact. Dolby Pro
Logic relies on the same decoding technology as the professional cinema processors to
decode the movie sound tracks that are found on video. The decoding process results in four
separate sound tracks which are Left Front, Center, Right Front, and Surround. The Dolby
Pro Logic decoded surround signals are monaural, but are reproduced by a non-directional
loudspeaker on each side of the listening area to help diffuse the sound. The Dolby Surround
concept is the heart of the Home Theater audio and video experience.
Dolby Surround encoding is also used for MTS and satellite broadcasts as well as other
audio-only program sources such as compact discs. Use the C39 CINEMA 1 mode with its
Dolby Pro Logic processing to enjoy listening to these other program sources.
Home THX Audio circuits further process all the Dolby Pro Logic decoded signals including
the generation of separate spatially expanded left and right surround signals. Home THX Audio
also specifies that a subwoofer be used. A Home THX Audio system therefore requires six
discrete audio channels and six corresponding loudspeakers.
The C39 provides six audio channels to take full advantage of the exciting sound reproduc-
tion capabilities of a Dolby Surround encoded movie sound track. When the Mcintosh THX-M
module is installed in the C39 the audio enhancements possible by Home THX Audio signal
processing also will be available.
Descriptions of the functions of each channel of a Dolby Surround soundtrack as decoded
by Dolby Pro Logic and the addition of Home THX Audio processing will assist you in better
understanding the use of the various controls, switches and operating procedures of your C39.
