That should be all you need to do. Now turn
on your TV or sound source, turn on your loop receiver, and set
it to the proper input. Make sure the balance is set to the center
or to the side you chose for the input. Set your hearing aid
to the "T" setting and turn up the volume on the loop
receiver until you can hear it. I generally have to turn mine
up 3/4 of the way or more for best results.
Because this produces a small magnetic field,
it has the potential to bother some sensitive electronics. I
have experienced no problems in either location I have set up
my system, but I guess there are problems in some theater applications
especially (electric guitar pickups are an example). But those
systems often use significantly more power to the loop creating
a much bigger magnetic field than you will need. The only real
problem you may run into is if you are living in the dorms or
in an apartment building where other hearing aid users may be
located above, below, or to the side of the room where your loop
system resides. If your system has a lot of power and is turned
up really high, or possibly even at a normal setting, people
in other rooms or apartments may be able to pick it up on their
hearing aids while trying to talk on the phone or use a loop
system of their own. For this reason I would recommend turning
your system off when not in use, and if it does cause problems
like I described, you can try adjusting the volume so that you
can still use it without bothering the neighbors. Ultimately
there may be no good solution beyond that. Fortunately I don't
think the problem would exist very often if ever.
I have often thought that this would work
really well in a car too. Simply use a car amp, and the same
wiring method. It may require wrapping the cable around the interior
more than once to get it long enough, even with multiple conductors
inside. But you also need to consider that car audio usually
operates on 4 ohms, or sometimes even at 2 ohms impedence, so
be sure to take that into consideration when creating your system.
I know that a lof of what I described is
very technical, requiring a bit of knowledge about electronics
and wiring. It also requires you have a soldering iron and multi-meter.

I would be happy to demonstrate my system
for you and help you build one of your own.
