Active DI running on phantom power question.

    I've recently picked up a Countryman Type 85 active DI and I was searching as to whether or not you could run a guitar with active pickups into the front considering it doesn't have a pad, and I found a page saying that you shouldn't leave the instrument plugged into the input while the unit is running on phantom power. Why do you think that is? I know that when it is running on batteries you shouldn't leave it in because it would drain the battery, but when it's running on phantom power it's different.

    It will handle passive or active pickups. It purely consists of a FET follower, configured to handle up to 5V pk-pk with the switch in the "pickup" position.

    Where's the reference to not leaving the instrument plugged in when on phantom power? I couldn't see anything that said that.

    I suppose the GS quote you mean is "...don't leave it plugged in to the input side when not in use with phantom."

    Performing a lexical analysis on this clause gives alternative meanings, depending on what the phrase "when not is use" is modifying. If you take it as modifying "with phantom", you get the result "when not in use with phantom", i.e. when running on battery, and in this case, the advice "don't leave it plugged in to the input side when running on battery" is correct. The opposing construct of "when not in use" modifying "leave it plugged in" gives the wrong resulting sense of "with phantom, don't leave it plugged in to the input side when not in use".

    There, we can all have fun analyzing what appears on GS.

    Hmm, it makes so much more sense when I hear it from you. Haha, that's probably what he meant. Thanks.
