If you have identified that you have a Missing/No Earth, then the Groundhog+ is for you. Its sole objective is to put the Ground/Earth back into your system and banish those unwanted, audio pests. No predicting the weather with this hog! All you need to do use a standard IEC power cable to connect the Groundhog+ to your audio system. The Groundhog+ then adds back the missing Ground/Earth connection to dissipate noise.
