Remember when your stereo and your
television were considered two separate items?
Well, if you walk into an electronics
store these days you'll find things are very different: a
home theater system lets you watch video tapes (or laserdiscs,
DVDs, broadcast movies and concerts) with audio and video
that simulates the movie theater experience.
And there are no disturbances
from strangers' conversations or commercial interruption.

Choose your receiver
The receiver is responsible
for taking pieces of a movie soundtrack, such as the sound
of a jet plane taking off, and sending it to the speakers
in such a way that you can hear the plane coming from
behind and passing over you. To get these effects, you
have a few choices to consider:
A receiver
with a Dolby Surround Sound decoder is the most basic choice.
This system feeds the front speakers with the program in
normal stereo, while the back surrounding speakers are fed
a basic signal that doesn't have much separation.
For a more enhanced sound with higher separation, you'll
need a Dolby Pro Logic decoder. This is like an electronic
traffic cop: it'll direct the appropriate sound to the appropriate
channel, which feeds into the appropriate speaker, giving
you much more localized, life-like audio.
Finally, there's Dolby Digital,which has even more sound
separation, adding a sixth sound channel to Dolby Pro Logic's
five, for powerful low-frequency effects .

Choose
your video source
At the
moment, you have three choices for a video source. Although
with the speed that new technology is hitting the market,
this may change soon.
The first and most basic
is a hi-fi VCR. The difference between this and a normal
VCR is that the hi-fi provides audio information for the
Surround Sound or Pro Logic receiver that an ordinary
VCR can't. (The cost, however, is not that much more.)
Fancier models will give you more control over how you
record something than a cheaper model will. Reproduction
of a pre-recorded tape's soundtrack will probably be superior
as well. But unless you're an educated listener, you won't
notice the difference. For the majority of us, a less
expensive unit from a reputable manufacturer will be just
fine, as long as it has audio out jacks.
Next is the laserdisc player, which gives you a much sharper
picture than you can get with most VCRs, or on cable or
broadcast TV. Some of them incorporate a CD player and
the best play both sides of an album-sized disc without
you having to flip it. If you have a big-screen TV and
notice picture imperfections easily, you may really appreciate
a laserdisc player.
Finally, the DVD player, which is the latest in video
technology and produces a slightly better picture than
the laserdisc. Unlike laserdiscs, DVDs are CD-sized, which
makes for easier storage. For sound and video quality,
you can't get any better than this (at least not yet).
Again, the higher quality sound and picture will usually
mean a higher cost, with DVD players running the highest.
Other drawbacks for DVDs (and laserdiscs) are selection--you
have a far greater number of choices with a VCR--and the
ability to record. Still, wait a couple years and these
problems may disappear.

Choose
your television
How big a TV do you want?
And what quality would you like your picture to be? Those
are the questions to ask yourself. Just about every TV
under 30" (diagonal measurement) will be fine, as
long as you stick to renting tapes and watching cable
(or broadcast) channels. If you are a critical viewer
and own a laserdisc player, DVD or have the new Digital
Satellite System, you should definitely consider a better
quality TV.
Don't worry about having
a stereo TV. Your video source will take care of the sound.

Choose
your speakers
Speakers are important.
Everything you hear comes out of them, so follow these
tips for your listening pleasure:
Buy the best ones you
can afford--avoid low-quality speakers, even if they're
inexpensive. Five speakers are needed for a Dolby Pro
Logic or Dolby Digital system: two in front, two behind,
and one right at the TV.
If you like, add a subwoofer to produce superb bass sound.
It's a luxury, though, not a necessity.
You'll get the best results for home theater if all five
speakers are of the same brand.
On the other hand, if
you're also using the system as your musical listening
center, you'll want your two main (front) speakers to
be the best quality and matched.
Subwoofers come both powered
and passive. The former is better, if you have the money.
If you don't, a passive subwoofer and powerful receiver
can still be a very good combination.
When shopping, look for speakers that are heavier than
they appear. Grilles should be removable and have at least
two drivers underneath: a larger woofer and a smaller
tweeter. The speakers nearest the TV have to be magnetically
shielded, so they don't make the picture wacky.
Follow the directions
(take it slow), pop your popcorn, pop in your video and
get as comfortable as you please--remember, it's your
house, not the theater.
