Hello everyone,

I've just bought a Behring Ultra DI - 400 for use in my studio, as when using my Stratocaster and Telecaster in the HI-ZI input of my Apollo Twin MK2, on some Amplitube presets, there was so much hum and noise and was advised to get a DI box.

When I plug everything in, the guitar to the DI Box and then out to the Apollo Twin, I can barely get the input on the Apollo Twin up to half way before things start noise starts getting introduced, but also, when I enable the 'lift' switch, there is so much noise, like interference etc.

Why is this?
Anyone able to help?

Thanks

 

RF interference? Have you ever tried it with a different interface at your location?

I once had to build a faraday cage to cut out interference for recording guitars in a fairly heavily populated municipal locale....
