Home Theater Systems

[Myauk]

Now I am preparing maunal for HTS system DVD Player and FM receiver.
I understand that the surround sound systems depends mainly on the use
of different speaker modules for different frequency ranges
transmitting sound in different directions.
And the delay time is set so as to have the best quality of sound at
home as if it were in a Theatre.
Is it correct?
Somebody said that there might need sensors to adjust the sound of the
speakers so as to give the correct volume, direction and quality of
sound and I am getting confused!
Until now the sound sensors are not used in HTS sytems according to my
knowledge.
What are your opinions?

I have an Onkyo home theater receiver that has a microphone input. It's for
setting up the speaker output level, frequency cutoff, phasing, and delay.
You just plug the microphone in and take a series of readings from three
different listening positions. The receiver automatically sets it all up,
takes only about ten minutes to go thru the procedure. Seems to work fine,
it sounds great.

The main use of delay, which should normally be applied equally to all
speakers is to compensate for the processing delays in the video
monitor, so that speech is in sync with lip movements. A normal CRT TV
has basically zero frames pocessing delay, but a LCD/ flat panel may
need up to 8 frames sound delay.

The idea of having a sensor is probably self defeating and will end up
causing more problems than it cures, although some professional delay
systems, for large auditoriums, for example, do have air temperature
compensation, as the speed of sound changes with temperature

I suggest that you post this question on rec.audio.pro and look for
replies from people like Scott Dorsey.

It is used as a setup tool and may well not be part of the final installed
system. The other posters delineated the usage for setup quite well.
