The THX system is not a recording technology, and it does not specify a sound recording format: all sound formats, whether digital (Dolby Digital, SDDS) or analog (Dolby Stereo, Ultra-Stereo), can be "shown in THX." THX is mainly a quality assurance system. THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer. THX also provides certified theaters with a special crossover circuit whose use is part of the standard. check here

THX optimizer is not a testdvd but a test that is on some THX approved dvdfilm. With THX optimizer is possible to adjust the sound and image in a quick and easy way. Before each adjustment of audio and video it says what to listen using various test tones, and what to look for using the various test boxes and color boxes.

List of the test facilities are in the section which deals with the sound (audio).
The test tone to adjust any speaker in the same level.
With this test tone, there is an opportunity to hear about the speaker cables are inserted correctly surround receiver / amplifier, if they play in phase or oppositional. This means that in English, plus from the speaker, plus sit in on the receiver / amplifier and less sitting in minus. If they are not really play in oppositional and it does not sound good.
Here is a test tone is used to check the subwoofer crossover frequency.

There have been many rumors about the THX optimizer is optimized for the dvd film the program is on but that's not true!. There will be used the same master to all dvd film having THX optimizer program so there is no difference in end result.

If you have the option to save multiple settings of projector and TV, it is advantageous to calibrate THX optimizer from a dvd film in PAL (Europe) and a dvd film in NTSC (USA) because there is a slight difference in the final result on Because of the difference between PAL & NTSC picture.

A THX trailer consists of stunning audio and visual effects, with each trailer taking on its own personality. check here

Setup your new HDTV or projector for better picture quality in just minutes. Many THX Certified DVDs and some new THX Certified Blu-ray titles feature THX Optimizer (including some you may already own). THX Optimizer is an easy-to-use, on-screen calibration tool for home theater systems.
