The Samson MDA1 is an affordable and straightforward DI box that gets you from point A to B, converting unbalanced 1/4" instrument level signal to a balanced line level signal without drilling a hole in your pocket.

There aren't many controls to fuss about either, just essentials which include a 15dB input attenuator and a ground lift switch, both of which are practical additions that will not distract from its main function.


  • Input 1/4", XLR Output, 1/4" Thru
  • 15dB input attenuator, ground lift switch
  • Runs on 9V battery or 48V Phantom Power
  • Frequency response of 18Hz–35kHz


As expected, most owners are happy with their Samson MDA1 because of the value that they get for its affordable price. Overall market impression is positive, with plenty of users more than happy to recommend the unit to others. It also gets a lot of thumbs up for its transparent sound quality.


While there are no complaints about its performance or sound, there are some who wish for more features.
