A Home Theater combines the newest high fidelity surround sound audio concepts with
the high quality video reproduction of the latest big screen TV sets and monitors. All the ex-
citement of the special audio and video effects of today's action movies are now possible
in your own home using a laser video disc player or VCR as a source.
All movies produced by major film companies have soundtracks that are encoded with
Dolby Surround Sound. The decoding process is called Dolby Pro Logic and results in four
separate soundtracks which are Left Front, Center, Right Front, and Surround. This concept
is the heart of the Home Theater audio experience.
Lucasfilm Ltd. has developed a process for enhancing the reproduction of Dolby Pro Logic
movie soundtracks by adding additional signal processing to all the Dolby decoded sound-
tracks. This process is called Home THX Audio.
To experience the maximum pleasure from your Mclntosh Home Theater System, the elec-
tronics and loudspeakers should be set up as closely as possible to the recommended con-
figurations. You may find it convenient to take advantage of the technical knowledge and ex-
perience of your Mclntosh dealer to assist you in the setup procedure.
Reproducing Dolby Surround movie soundtracks with Dolby Pro Logic decoding requires a
specific selection and location of loudspeakers. If you are using the optional Mclntosh THX-M
module in your MX130 for Home THX Audio processing, the requirements are even more specific.
Mclntosh has introduced the HT Home Theater line of loudspeakers specifically designed
for home theater use. These loudspeakers include models for Left Front, Center and Right
Front, Surround Sound and a Subwoofer. The Mclntosh HT Series loudspeakers are licensed
for Home THX Audio, and are ideal for reproducing Dolby Surround encoded movie sound-
tracks using Dolby Pro Logic decoding as well as Home THX Audio processing enhancement.
These loudspeakers also reproduce normal stereo music sources such as a compact disc
with outstanding fidelity.
Mclntosh is also manufacturing the Model MC7106, six channel power amplifier, specifically
designed for Home Theater use. The MC7106 is also licensed for Home THX Audio and in-
cludes a convenient 25 conductor THX connector that accommodates a computer type cable
to receive all six audio channels and AC power control from a matching connector on an
MX130 Control Center.
Dolby Pro Logic decoding produces four specific channels of audio information from a Dolby
Surround encoded soundtrack. These channels include Left Front. Center, Right Front and
Surround sound.
The front left and right loudspeakers provide the fundamental two channel stereo music
and sound. The center channel is also called the dialog channel since it reproduces sound-
track dialog information. A center channel greatly increases the intelligibility of spoken dialog.
The three front loudspeakers should have wide horizontal sound dispersion to allow the
effective area for audience participation to be spread as wide as possible in the home theater
room. The vertical acoustic dispersion of the front speakers should be restricted to avoid
floor and ceiling reflections that could interfere with the indirect reflected surround sounds.
The Dolby Pro Logic decoded surround sound signal is mono, but requires two separate
loudspeakers. One is mounted on the left wall of the listening area and the other on the right
wall. They should be approximately at or slightly above ear height. For the correct ambience
effect, surround sound must be non directional and reflected from the room wall and appear
to come from all directions, rather than heard directly from the loudspeakers.
The addition of a subwoofer can greatly enhance the enjoyment of your home theater. A
subwoofer can reproduce the exciting low frequency music and sound effects of today's action
