Ground loop isolators and audio question....

[TheAxeman]

I want to run the audio from a Sirius radio and from a Passport radar detector through a Starcom Advance. I understand that I will need a ground loop isolator which I have purchased through Escort for the detector and I'm assuming I need one for the radio also. My question is this. Is it necessary to run seperate isolators for each gadget or do they make a centralized type of isolator which I can run numerous items through? Any suggestions on where to get these things inexpensively? I know I can get one for the Starcom through Bike Effects but $45.00 seems a little pricey considering even Escort sells them for $24.00.... Are there different kinds based on the type of electronic gadget?

Electrical Connections make them.

You really need one on each bike to protect the devices from forming ground loops through each other.

The MixIt2 unit is supposed to have an isolator built-in to it's two mono inputs for radar and GPS.
