Hey there,
For I'm using a pair of Gemini XL 500ii's with a Numark N4 as an interface.
One turntable shows a perfect scope but the other doesn't (see picture for what it does show)
Not sure why this is? Ive replaced the rca and ground cables and also the needles and it still plays up.
Anyone else had a similar issue? Anyone know how to resolve it?

Please Help

Thanks
James
