When you touched your device, did the hum/buzz noise increase? Well, in most cases, this is likely to be caused by a missing Ground/Earth connection that normally shields your system from such interference and drains away the noise.
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. Our Groundhog is multi-talented as it includes a variety of connections to suit just about any audio system.
