Stereo Surround Speakers
No sound from the surround speakers when testing "in phase"?
When testing my stereo surround speakers using the THX Optimizer, the rear speakers put out no audio at all when the evidence "out of phase. Is this normal?
I think that is normal. Whenever test the speakers manually, for the second phase, I'm sure they do not want to be more than 2 sources. It is quite difficult for phase 2 testing speakers, let alone 4. If optimizer has special software that can do it - is new to me, and I would be very impressed! ..
Stereophile used to dominate a small elite crowd of fans who have come to greatly appreciate and enjoy the technological advances of the time he appeared first brought home stereo and listening to a higher level of sonic realism and aural pleasures never before achieved with mono playback systems house. That was in the 50s to mid-century. Over the years, the stereo sound has become the de facto standard in the music recording studio and reproductions systems.
Meanwhile, you have the television that brought moving images to homes in what was once a movie theater preservation. For a time, the Boards of film felt threatened by the new consumer technology, but in time, the two lived in symbiotic existence. Culminating in color television and the system VHS recording, home entertainment came to an end of the road on the way it was late 80s.
Digital Think and Thank
It was not until the introduction CD of the music in the 70s and DVD for movie playback in the home of the 90 that the evolution of the system of home entertainment has entered a new stage. It is now almost entirely digital. Almost, because the sound that you hear the speakers will be analog and digital if you never hear, everything is noise.
But it is technology that allows music and moving images to be encoded in a small disk and decoded or played at home. It was at that time the PC home computer was also taking shape. It was no coincidence that the digits used to encode music and video is also supported by the fundamentals of the instructions the computer that make the PC useful.
It was only a matter of time when data representing the vast digital music and movies became available on the PC also. All that was needed was the computing power that was growing almost exponentially every year from companies like Intel, AMD for the PC and Motorola for the Mac
The DVD, High Definition Video and High Resolution Audio
Leaping from one decade to the present, has high definition television sets showing the real life images that can make the best Sony Trinitron TVs 90s look anemic. And you have the high resolution music DVD and audio CDs can play improved in 8 channel surround sound that puts you right in the middle of a performance or concert.
These devices Listen to them are virtually on their own computers. The LCD and Plasma Screen Televisions hundreds of thousands of pixels, depending on the size of your screen, each one a real team, who plays The OS and 1s of a digital instruction to display 16 million colors on variations of each of the frames of a moving image.
The computing power for this staggered the scientists who work at NASA when they started putting the first man on the moon in 1969. But today, half a century later, the reality were caught in the science fiction of the past. The same is true of the high resolution of the music that comes with the latest Blu-ray for now are the versions elitist for DVD everywhere.
Going digital has the steps for home entertainment a reality. Processor chips that decode gigabytes of data stored in laser discs are only one degree lower than the chips from the same, such as Motorola and Intel responsible for supply and portable PC manufacturers. With the power calculation to make further progress, you can expect from home entertainment to get even more real with 3-dimension holograms you see in the movies modern science fiction. GP
