Aged_Cheddar Posted May 20 Share Posted May 20 I did look around, but I didn't see any existing threads about this so here goes.... I had a gig a few weeks back, in club I've never played before, well for the first time ever I got a HELL of a ground loop hum, I tried multiple outlets, different cables etc... Fortunately the sound engineer had a spare DI for me (Whirlwind IMP2) , though I'm not sure we ever got me gain staged good...is it possible for me to clip a DI? I think I was... Anyway, I don't EVER want that headache again, so I'm putting a DI directly on my board, it's going to be a basic passive Radial Pro DI, or JDI. My question is...what signal from my HX Stomp do I feed into the DI?? Instrument or Line?? In case it matters, I play bass, single channel so stereo isn't needed. Thanks in advance!

rd2rk Posted May 20 Share Posted May 20 Instrument Level: ProDI Features - Radial Engineering It'll also take a LINE level, has a PAD switch and a Ground Lift. 1 Quote Link to comment Share on other sites More sharing options...
Schmalle Posted May 20 Share Posted May 20 DI boxes use a small transformer to isolate the signal. These can be driven into saturation - at what levels depends on the DI box. Instead of a DI box I have 2 short TRS -> XLR cables. On one of them the shield is not connected/cut in case I need a ground lift. This works because the HX Line Outs are (impedance) balanced. I use instrument level by default. 1 2 Quote Link to comment Share on other sites More sharing options...
rd2rk Posted May 20 Share Posted May 20 The Radial's transformer is heavy-duty, designed with the saturation problem in mind. 2 Quote Link to comment Share on other sites More sharing options...

Yeah that IMP2 had no pad switch, and I was hitting with line level gain, so I was probably clipping it...I would have though the sound guy would have caught that? But to be fair, I'm just as much to blame for not knowing my s***. Thanks for the help peeps! Do either of you want to make a suggestion on which of those DI's are better? I mean the ProDI is more around what I'd like to spend, but I certainly can afford the JDI if that Jensen Transformer is that much better? Thanks Again!!

rd2rk Posted May 21 Share Posted May 21 Radial is pro quality. I'd guess that the JDI uses the same transformer as the ProDI, just has more features. Read the descriptions on the Radial site and if you don't need the added features, get the ProDI. As for the "Sound Engineer", he was probably the waitress's boyfriend moonlighting from his day job at Guitar Center... 1 Quote Link to comment Share on other sites More sharing options...

I laughed harder at this than I probably should have. LOL! Thanks! Quote Link to comment Share on other sites More sharing options...
