Jan (and others),

If you're looking at getting the BP100, then you may want to look at the Audio Adapter for the BP100.. Right now on Cochlear's Store, they have the Audio Adapter for the BP100 on sale:  

Price:  $247.00  $123.50
Save: 50% off

Just saw that and thought some would be interested..

Here's a direct link to their store:  http://www.cochlearstore.com/index.php?main_page=product_info&cPath=45_51&products_id=266

Don't know how long it's on sale for..  But, for less than half the regular price, it's worth looking at buying if you're getting the BP100 or have it already.

Regards,
Brian

Thanks for the heads up, Pooter.

Wow. It has an isolation transformer. It protects the user from power surges, so maybe Lori can stand under a tree during a lightning storm after all.

YES!  An isolation transformer.  That's exactly what I've been saying I needed.  Isn't it?   ???

Jan, I would buy it for you, but you are worth so much more to me than half price. I just wouldn't feel right about it.  How about I just sing really loud into your good ear?
You'll be begging to be deaf in that ear too before too long!

Now if they'd just run a sale on the actual BP100, that would be a good thing.   About the only thing I can afford on their website at the moment is the fishing line and the little stuffed koala bear!

Seen the fishing line - must have missed the little stuffed koala bear.  Is it comparable to a Zhu Zhu pet??

Half price wouldn't insult me at all.  Buy away.  Do you need my address again??  LOL

Better get back to the topic @ hand before Phyl finds our halos slipping.  Happy Holidays, Phyl  :-*

No problem, I got the fishing line thing for my halo too!  It can't get too far away now.

BACK ON TOPIC, people.   >:(

Lori,

Would that be the 8 lb test fishing line or the 10 lb test line?

Ooops.. I think I see Phyl!  Back on topic, people!  Sheesh!

Damn, Pooter.

When I saw you had posted to this topic again, I thought you were going to volunteer to buy not only me, but Lori, an audio adapter.

Phyl must be sick or something - she's usually caught us by now  :o

Last off topic reply from me on this thread, Phyl.  I swear  ;D

I can't promise that Lori or Pooter will behave, though  ::)

Just like a big sister.. do something wrong to pull us young'n's in, and then stand back and point out the fact that WE'RE doing something wrong!  How very big sister of you!  There goes THAT Christmas idea..  ;)

We're kinda still on topic, though..  we were talking about you buying Lori and I an audio adapter for our BAHA.. oh, damn.. I don't have one......yet.  :)

I'll behave now..

Just keep making random references to isolation transformers. It sounds so . . . technical.

Those ISOLATION TRANSFORMERS cause ALMOST as much trouble as Jan!   ::)

Oh come on!!! They don't even come close  ;)  :D

Anyway, getting back to isolation transformers, someone who understands technical things (Pooter maybe) please enlighten me on the concept.  Just how do they work? - and why do I want one? (I'm almost certain that I do).  Afterall, I don't even know how to program my VCR - or my DVR - that's what kids are for  ;D

Thanks,

So, you're a 12:00 flasher, eh Jan?  ;)

Isolation transformers are built typically with a 1 to 1 ratio. Five volts in is five volts out. The protection comes from the fact that the second coil is not connected to the first, which is connected to mains. As a result, touching a part of the circuit connected to the second coil will not result in a deadly shock. The design of the transformer depends upon the usage that the circuit will draw, typically resulting in larger and heavier transformers needed for higher current applications.

Isolation transformers are not just for isolating electronics from mains voltages. it is also useful for separating parts of a circuit so that power is transmitted while protecting sensitive electronics. Chips and sensitive electronics require a small voltage; anymore can destroy the chip. In contrast, motors, solenoids, relays and many other components require larger voltages. These circuits may need to interact, and the device that protects the more sensitive components is the isolation transformer.

In short, having an isolation circuit in the audio adapter keeps you from being shocked by the power from the iPod (or other devide) through your BP100.

Something like that anyhow..  (*in a hushed voice* Is she gone yet?  ;) )

Brian

Oh fine, Pooter. Now you've gone and stripped away all the mystique and it's not going to be any fun to say isolation transformer any more. Thanks a lot.

Geez.

Thanks for the very well-written explanation, Pooter.  Heck, even I can understand it.

I just don't have a brain for this kind of stuff.  I'll have to ask my docs if they removed that part during my "surgical extravaganza".  :D
