EASY WAYS TO MAKE YOUR HOME THEATER PERFORM, AT LITTLE OR NO
COST!
A chain is only as strong as its weakest link. No matter how
excellent the quality of your HDTV, 18" DBS receiver, or
DVD/DVD-AUDIO player, it'll never see the light (or sound) of
day if
The interconnect (if there's a jack for it) which yields the
highest quality is not employed.
The cable isn't sufficient at isolating the signal from other
signals, or limiting signal loss through "leakage."
So here are a few basic tips you may or may not already be aware
of, that will increase the probability you'll extract the
highest quality your audio/video gear is capable of providing.
1. REPLACE ORIGINAL CABLES: Those "free" ones which come with
most components may have a quality "look", (especially since
manufacturers of generic interconnects started placing "gold"
plugs on them), but beauty & quality is not just skin deep.
And you'll notice how shallow it really is as soon as the sound
becomes "fatiguing", or you get a "short" in one, or you begin
experiencing degraded aural & visual quality, along with an
increase in interference.
Use discretion though; it you have a $3500 HDTV-ready
television, a $3.99 package of A/V cables from VIDEO-R-US should
raise a flag.
Conversely, a $100 TV from Bill & Ted's Wild Appliances and
$90/meter Monster S-VIDEO II cables might be a tad much.
And you don't have to replace all the cables in your system at
one time (which could be rather expensive!); do it as budget
constraints permit. 2. USE THE INTERCONNECT TYPE YIELDING THE
HIGHEST QUALITY: If your components provide the output & input
jack(s), use them, unless it prevents you from utilizing some
particular function unique to your viewing/listening habits &
hookup.
That means COMPONENT VIDEO (if available) or S-VIDEO for video,
and RCA for audio. When S-Video isn't available, that means RCA
for COMPOSITE VIDEO.
3. KEEP SIGNALS IN ONE FORMAT AFTER INITIAL CONVERSION: With
COMPOSITE VIDEO, all color & b/w signals (3 signals total) are
mixed into one signal. A "comb filter" in your video equipment
must then "un-separate" them all to process the picture.
With S-VIDEO, a separate color & b/w signals (2 signals total)
are provided on the one cable. When your video equipment
receives an S-VIDEO signal, all it has to separate is the color.
A "comb filter" is not used when using S-VIDEO.
With COMPONENT VIDEO, 2 separate color-difference signals, & a
b/w signal (3 signals total) are provided on 3 separate cables.
When your video equipment receives a COMPONENT VIDEO signal, all
it has to do is derive the color from the color difference
signals.
With RF, all color, b/w and THEN audio, PLUS a "carrier"
frequency are mixed together in one signal. A whole lot of
separation has to take place with RF! But it is ideal for
multiplexed long distance signal transfer. So based on the
format of the signal received, each "video processing" piece of
equipment you have must first unconvert then convert, unconvert
then convert. Something gets lost in the shuffle; it's called
SIGNAL QUALITY.
So unless you have No Choice, only use RF cables/signals for
relaying broadcast signals from outside to wherever your cable
boxes, satellite receivers, TVs, or VCRs are located.
If COMPOSITE VIDEO and/or S-VIDEO and or COMPONENT VIDEO signals
are output by these devices, keep them in these formats
throughout the rest of your equipment chain....if possible.
4. ROTATE RCA INTERCONNECTS AS YOU INSERT & REMOVE: This will
help remove oxidation on the jacks & provide better signal
transfer.
With S-VIDEO, DO NOT TWIST: line up "notches" on plug with jack,
and push straight. Otherwise you may damage the "pin assembly."
And if you paid for some nice ones, you'll scream very loudly.
5. WHAT GOES IN, COMES OUT: By knowing "what" functionality you
desire from your hookup (e.g., "I want to be able to watch DVDs
without tuning to channel 3 or 4"), & utilizing the previous
tips on keeping the signal in one format, you can USUALLY figure
out how to hook up your equipment based on the input/output
jacks available to you.
All you have to remember is Outs go to INs & vice versa. 6.
WATCH WHERE YOU ROUTE POWER CORDS: Sometimes, lower-quality
interconnects pick up AC Hum from AC cords. Also, I recommend
you invest in some good quality "surge protector/line
conditioners (Panamax, Monster Cable, etc.,) to plug your
components.
MOST damage occurs to home A/V electronics from prolonged
exposure to the continuous, "common" surges generated by garage
door openers, refrigerator and A/C compressors turning on & off,
& local power utility company power grid switching.
