DIY PAD cable

I was having a few difficulties recently when trying to record drums with the C24 in studio 2 - even with the mic gain turned all the way down, we were still clipping the inputs to Pro Tools.

On the day of the session I worked around this by using external mic pre's, but I wanted a better solution.


A little bit of research and soldering later, and I turned up with this:


(at the other end of the lead is a standard XLR female connector)

The circuit fits quite neatly into the chassis of an XLR male connector (it's important to make sure it goes on the desk input end of the signal, so I'd avoid wiring this into a patch cable), and does the job quite nicely.

I made the cable about a foot long, and you simply daisy chain it to the end of a mic lead. They've turned out to be so useful, I'm in the middle of making another half dozen of them.

  1. how much does it attenuate?

  2. Around 20dB (theoretically 18.5dB).

  3. THis is a great DIY suggestion when the microphones you use for recording don't have a -10dB Attenuator Built-in! Thanks for posting this! I shall put this into a Male-Female connector!
    Do you have one for a DIY Low-cut filter too?
