    Comments about Behringer ULTRA-DI DI400P Passive Direct Box:

    I've never had the $$ to spend on a Radial or Countryman DI, so I cannot compare the difference (nor do I imagine there's a $100+ difference in sound quality). I have two of these already, use once a week and they do the job. I know it's not the best one out there, but it's the most affordable and it works for our church. If you're looking for a DI box that you can afford, this will do.
