“WOW!”— A User’s Guide
The “WOW!” laser disc was created by
Lucasfilm for use with Home THX Audio systems.
“WOW!” consists of exciting demonstration,
educational, and testing material to help you best
appreciate the Home THX Audio System. “Wow!”
is available to consumers with the purchase of a
Home THX Audio System controller.
“WOW!” should only be played through a
Home THX Audio System, and should never
be sold, rented, copied, broadcast, or used for
any commercial purposes. Any unauthorized
use of this copyrighted material is strictly
prohibited, and violators will be prosecuted.
The following table of contents outlines the vari-
ous chapters on the WOW! laser disc, and pro-
vides some suggestions on their use.
Side 1:
Chapter 1: WOW!;
This is a remarkable thematic montage of
various George Lucas films, with fast, tight editing
to emphasize interest and excitement. All of the
soundtracks are essentially unchanged with one
exception: a new musical score was commis-
sioned to tie the entire piece together. WOW!
provides a short and complete movie going
experience, and shows off all of the potential of
the Home THX Audio System. WOW! contains a
wide variety of sounds, from very quiet passages,
to loud, explosive ones; there are sounds pan-
ning between Left and Right, and from front to
back; there is soft dialog buried in the midst of
competing, loud sound effects; there are power-
ful, deep bass sounds that make you feel fully
involved in the action. The Home THX Audio
System will deliver all of these sounds with star-
tling realism, and unequaled clarity!
Chapter 2: The Home THX Audio System;
Tomlinson Holman discusses the elements
of the Home THX Audio System and what sets it
apart from more conventional home theatre
systems.
Chapter 3: Mode Selections;
Five short selections illustrate the most
appropriate use of the various modes of your THX
controller. These selections show the best use of
the Home THX Cinema, Dolby Pro Logic, and
Stereo modes.
Side 2:
Chapter 4: Soundtrack;
This chapter outlines the process whereby
the soundtrack of a movie is created. It gives you
an appreciation of what you are missing when you
watch a movie on a non-THX system. There is far
more to making a film soundtrack than most
people imagine.
Alignment Test Signals:
Chapter 5: Input Level Calibration Tone;
This 1 kHz tone is recorded at 0 dB (Dolby
reference level), and can be used to calibrate the
input level of your THX controller. Adjust the level
so that the meter on the controller reads
0 dB(reference level) when this signal is
playing.
Chapter 6: Pink Noise, Left & Right, In-Phase,
-10 dB;
This signal is comprised of broad band noise
and can be used to adjust the Center output level,
or check the phase of the Left, Right, and Center
speakers, as well as the Subwoofers. When
played back through a correctly adjusted system,
this signal should yield 75 dB SPL (Sound Pres-
sure Level) on a sound level meter, C-weighted,
slow mode.
