| This is a Schematic of the Interface so that
you'll understand exactly what it does and how it works. Of course all you have
to do is install it. It does the rest for you automatically.
1. This is the Plug that you plug into your sound card. The end (tip) is the
left channel hot, the center band (ring) is the right channel hot. The Sleeve
is the common ground from your soundcard. And this will be broken at the transformers.
2. Now we're getting to the important parts. 2, 3 and 4 are actually all parts
of the precision low noise matched transformers. First, 2 is the 4-32 ohm input
side. Do you see how it has fewer coils/turns? That's so that when we get to 3
on the other side with more turns you'll see that the impedance is stepped up.
3. This is the HZ side at 47,000 ohms. A transformer works much like an electrical
generator. A current passes through the coils and it's transferred onto the other
side. Nothing touches and therefore the ground loop doesn't pass between sides
of the transformer. You could have a transformer like this that didn't correct
the impedance and it would work just fine for stopping the ground loop. But we're
fixing both problems here. Also, there are different qualities and noise levels
and this is a superb low noise example, but you can't see that, you'll just hear
it. Anyway it all has to do with the precision of the wind and the materials used.
4. This is the center of the transformer. Note that to make the picture easier
to understand I moved down to the left channel, but both right and left channels
are identical and the are also both totally isolated from each other. No ground
potential passes.
5/6. These are the RCA Jacks that plug into the Left and Right Channels of
your stereo system or home theater system. There's nothing special about them.
They're just standard RCA plugs. Oh, and they also plug into the 10' special extension
cable that we've included with the interface so that you have 16 feet of cable
to run between your computer and your stereo system. You can also add 2 more 10
foot cables without suffering signal loss. You can get those after you click the
buy button on the review page and look just below my shopping cart. Just add one
or two if you need them.
