Better Ground Loop Isolator than Radio Shack

I have the Harman/Kardon Drive+Play and had lots of ground loop noise.

I bought a ground loop isolator from Crutchfield. Abt $25 with shipping. I've only had it about a week, but it seems to be doing the job very well. Nice and quiet.

It has standard 1/8 inch miniplugs, too, so there's no need for adapters to RCA.

I'll be needing another Ground Loop Isolator for the house. Maybe I'll get this one and use it in the Prius and take Radio Shack one I have there out for the house.

Thanks for posting!

 

GLI's kill all your frequency response. You would better off with an FM interface. Check out "This sticky topic is a list of hardware products/mods currently known to work with the Prius " on this site for a fix.

How are you guys buying those things!? Every time I look it is out of stock. I'm on the notification list, and I have it in my cart... been that way for months, and it never seems to come into stock!

It all depends on whether they're FET based or transformer based. (well, II think most of the FETs need a sink transformer too...). There doesn't have to be signal loss with either design - it's just that vendors like to sell $12 parts for $60.


Generally you'd do best with an FET based isolator, but requires a power source...

Huh. The notification system must not work because I ordered and received the crutchfield one about a month ago.

 

Well, if you know how to solder, you can build your own, but I'm guessing the Radio Shack alternative will cost less.

Sounds like I lucked out on the GLI thing. I have an aux box in for my Sirius receiver. It plays clean. I had to install a GLI in my sienna van for the aux box to aftermarket DVD...sounds very flat and low. DaveSheremata is suggesting that I should try a FET based GLI with a power source?

I just ordered mine from eBay, same price. $17.99 + $6>99 shipping.
I want to know what these guys are talking about with the FEB based GLI???

 

Crutchfield has them back in stock.

Quick question: Does only the XM radio cause the feedback or any device plugged into the AUX? I am asking this because I am trying to figure out if I should install it inside my dash or let it hang out of the bottom in case I have to unplug it.

I got this one too, problem solved!

 

Does this thing cut out the reproduction of treble and other high-end sounds from your stereo??

 

I am also interested in any first-hand experience regarding the extent to which the Crutchfield and Radio Shack GLIs affect sound quality. I just received a Kensington Ultra Portable Power Inverter and suspect that I would find a small reduction in audio fidelity preferable to the level of hum generated without a GLI. Thanks for any additional input!

 

The only thing I do not like is that I have to have my volume set at 40 when normally I have it at 20. So I have to remember to lower it before I switch from my aux line to the radio or be blasted out of the car. I am not sure if this is a byproduct of the isolation loop or the DICE unit.
