Audio Cables along with
their Video counterparts form an indispensible part of our lives.
Whether you wish to listen to some soothing music or desire to watch
a match or catch a late night show on the television, you require
your audio and video cables to be set right. Ever wondered how these
cables work? And how can you test whether they are in perfect balance
without having to call on the technician every time? Here is a peek
into some interesting facts about audio and SCART cables.
Audio or Speaker Cables
These are what make all the
difference in the sound quality of the movie you watch on the
television or the Home Theater and does not entail a simple wire, but
encompasses cables which can be quite expensive. But costly as they
may appear, their importance and the work they perform cannot be
undermined in any way. In general, speaker cables encompass stranded
copper which acts as a great conductor along with two wire strands
which represent the polarity of the terminals. They are linked to the
source in accordance to the respective input and output terminals.
Alternating current is passed through the cables from the amplifier
to the speaker which in turn produces sound in the way the tweeter,
woofers and drivers are adjusted in varying frequencies. SCART is a
form of audio-visual connector more prevalent in the United Kingdom
and Europe. It embraces 21 pins and can do the job of analog and
component video cables brilliantly.
How are Audio and Video
Cables Tested
If you wish to test if your
audio-video cables are in harmony, all you need to do is get home a
multi-meter. Multimeters are devices which can help you
identify a fault in any of the three connections of a balanced cable.
They come in both analog and digital varieties and measure
resistance, voltage and current of cables, thus used as
troubleshooting devices.
