Everyone knows that they have to consider just what kind of TV
they want in their home — will it be a 1080p HDTV or a 4K UHD. And what about size, how BIG will it be?
The same goes for the Blu-ray player that will be supplying video from disc or
perhaps subbing with “smart TV’ features
for streaming video or playing music. But what about the cables that need to
connect between the TV and the Blu-ray player or DVD player? Or the cable box or
satellite receiver that brings in broadcast and cable networks?
Good Cables Versus
Bad
Where once multiple connectors for both video and audio were
commonplace, now the HDMI cable rules supreme for video and, because it does
this too, for audio as well. So making sure that the best quality HDMI possible is used for these connection is a
must. That means brand names, because “unknown” HDMI
cables that might have come for free or are lying around might not have the
transmission speed that the video/audio signal needs to provide the best
results. And getting good results doesn’t mean spending hundreds of dollars
for these cables, like it did in the early days either. But it does mean that
you get what you pay for, and being price conscious is easy, since getting the
proper length of HDMI cable will help to avoid unnecessary costs as
well as insure a good connection. And while HDMI cables are prevalent, in a
normal home theater there will be other cables as well, for example, S-Video
and RCA type audio cables
going to/from legacy devices such as a VCR player. These are found mostly
populating an A/V receiver, which will of course have HDMI cables
attached to them for sending audio to the home theater speakers. So just as
with HDMI, it’s important to get quality cables for audio. This is especially
true of these “analogue” cables as they are more likely to
exhibit noise and interference if they are inexpensive (meaning poor materials
poorly constructed).
Checking the Connection
Everyone knows that if a battery connection gets all “crusty” the
battery won’t be able to transfer power correctly. The same can happen
if the connections to your home theater are shoddy. Since the HDMI cable (the bulk of all cables used in a home
theater today) holds itself in place through friction, it’s
important to make sure that there’s no strain pulling on it that could
cause it to loosen or fall out. That’s the easy part. What’s
a bit harder is to first make sure that the HDMI connectors on both the cable
itself and where it’s going to be inserted are clean and
free of dust and/or detriment. A few “wisps” of
a feather duster will keep the dust from gathering on an A/V receiver’s
top, or the tops of speakers, but what about the connectors on the back of the
receiver? Or the back of a Blu-ray player or TV? These can all benefit from a bit of dusting maintenance before the cables are
inserted (that includes optical cables for audio too). Want to make sure there’s
no dust that could cause issues? Then take a Q-tip and lightly “circle” any
connector that looks like it could use some gunk removed before inserting a
cable (but don’t insert the Q-tip into any connector since the cotton could
come loose). And if the connectors can’t be easily seen due to how they’ve
been placed, try a penlight or flashlight so you’re not working in
the dark.
Placement of Cables
Most people have televisions set against the wall or mounted to
the wall — whether they’ve done it themselves or had it done
by an installation service, for example, Just One Touch. In either case, there’s
going to be cables going from the TV to the various devices that supply it with
a picture. These cables don’t get in the way of anyone and can be
tucked behind the cabinet the TV is on or hidden inside a runner going up the
wall (if non-invasive means are in use), but what about speaker wires (which
are also cables of a sort) that have to trail from the AV receiver or from the
TV and go throughout the room if there’s a surround sound system. The wires
need to reach the left/right surround speakers and what’s important here is
to keep any weight from impacting on these cables. There are a number of ways
to do this: either will have to go under the rug (difficult to do by oneself)
or they will have to be on top of the carpet but placed under a runner so
people/pets won’t trip on them or trample them or the
cables will have to wind its way across the walls. Of course speaker placement
in the ceiling will avoid all this — but that’s definitely a
shout-out for a professional installer because of structural needs, electrical
wiring avoidance and city codes.
The attractive quality of a big screen TV or a set of surround speakers may
catch the eye, but it’s the cables that affect just how good
the picture and sound that will be seen and heard will be. Take care of the
cables and they will do their job and you can concentrate on what’s
important: enjoying your home theater.
Boxer briefs are men's briefs or clothing briefs that have longer legs than the standard briefs. They are like boxer shorts aside from that boxer briefs are more tightly fitting. Boxer briefs first came into the business sector around 1990. Before this, there existed some type of briefs however they were called mid-length or thigh-length men's briefs. Bout enders, in brief
