One thing I am confused about is why use a DI, when plugging my acoustic gtr, bass or keys works fine into my Pro Tools console? I just control the input with my instrument knob or the PT gain? please forgive my ignorance on the subject.......

I have a RMS passive DI. I am wondering if it is working correctly? The Att has 3 choices 0 20 and 40 db. I don't notice a volume difference when switching them?

I plug my 1/4 inch acoustic gtr cord into the input (50k ohms) and I have a 1/4 coming out of the Para Out (50k ohms) into my Pro Tools console.

I also am wondering if you could tell me the best uses for the on/off Ground switch and when to Have it on. And when to use the XLR Balance IN/OUT (600 ohms)?

thank you in advance,
paul

    General DI Suggestions:

    Attenuation = 0, only use -20 pad, or -40pad if your signal input is too hot...
    You should likely go 1/4"guitar in and use the XLR out to the console (it may need phantom power)...
    Only use the ground switch if your hearing any hum or ground noise...

    not sure what PT device you use, but the MBox at least has a 1/4" input that you can set to instrument level (Hi-Z), making a DI unnecessary. That said, an external DI could sound different or better, so you may want to compare.
