Just got a Sprout - love it with one caveat. There's an annoying hiss when the vinyl setting is selected. The hiss comes through my speakers and headphones, and happens even when my turntable is not connected to the Sprout. No hiss whatsoever with any of the other inputs, including Bluetooth. Does anyone have any ideas? I've disconnected every other component in my system other than the Sprout, and the hiss remains as strong. Disconnected light fixtures, no difference.
Does the Sprout need to be earthed no matter what? Very bizarre that it’s only at this single setting.
