You could wire in a ground lift switch to make it work for any connection. The down side is, it will probably get all kinds of interference if you dont use the charger connection. Note: Whilst the ground loop isolator will not degrade the quality of pictures on your TV, there may be a reduction of the signal strength. The ground for charging current and shielding will still be made from the charger connection and from the head unit up to the 3.5mm receptacle. You will need an additional aerial cable fitted with male coax plugs to connect to the isolator and your device. The Ground Loop Isolator is fitted with female coax sockets. The way to solve the problem is to break the earth connection in the aerial lead with our ground loop isolator simply plug it in between the aerial socket and your equipment and it'll eradicate the hum (and improve your enjoyment of the sound). If you still hear it when all the inputs are disconnected then the noise is coming from. Ground loop isolators are used to break the dc circuit path for the audio shield ground circuit. Make sure to turn or or mute the receiver when you pull cables. Circuit use specialised circuit il715e which have on the one side four ttl inputs and on the opposite side corresponding outputs. When the noise goes away that component has a ground loop. The reason is because your system is grounded in two ways through your interconnect leads and through your aerial lead. If you have a ground loop you want to find out where it is. It'll be there even when you're listening to your CD player through your system.

It's much more common now to connect equipment that has a TV tuner in it (your DVD recorder or Sky set-top box, for example) to a Hi-Fi amplifier or Home Cinema amp and it's this connection that's the cause of the hum. Or use a pair of passive Di boxes per channel, and wire their outputs together (you will need an xlr sex changer if you use this type of output), and wire the output of the mixer to one Di boxes input, and the other Di boxes input to the power input. If you've ever noticed a hum coming through the speakers in a system that includes a TV tuner - or any piece of equipment that connects to an aerial - it could be because there's a ground loop.
