What are the issues using a Passport 8500 and X50 with the Mix-It?
The Passport 8500 and X50 use a bridged amp design, similar though not exactly like the Garmin SPIII. Customer response to the original Mix-It revealed that some Passport 8500’s work fine with the Mix-It using just the mono to stereo cable supplied with the Mix-It Escort package (M1E) but others did not. Contact with Escort has revealed that they have a special Ground Loop Interrupt (GLI) cord available which allows the 8500 to work properly with ANY device. Escort has no idea why some of their detectors require this cable, and others do not. I believe there has been a design change, but they will neither confirm nor deny this. The Mix-It2 was designed to eliminate this issue altogether by building an isolation transformer into two monaural input jacks. All that is required to use an Escort with the Mix-It2 is a straight mono-mono 3.5mm patch cord. NO special cords are needed, which cannot be said of the competition!
