Behringer Ultra-DI DI20 Stereo Active DI Box

Electric guitarists, keyboardists and bassists will love the flexibility the incredible DI20 provides both in the studio and on the stage.

By flipping a switch, you can use the DI20 as a launching pad for two separate mono signals, a stereo signal – or a split-signal feeding two separate amps. The DI20 also features a superb ground-lift switch, and the 3-position input attenuator can accommodate input levels of up to +48 dBu. This handy built-in attenuator also allows you to connect directly to your amplifier’s speaker outputs, even amps rated as high as 3,000 Watts. You can power the DI20 with either a 9 V battery or your mixer’s phantom power supply (+18 to +48 V DC). The whole package is wrapped in an ultra compact, road-suitable and rugged metal housing.




  • Professional and multi-purpose direct injection box for stage and studio applications
  • Provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers
  • Converts 2 independent unbalanced 1/4'' TRS line inputs into 2 balanced XLR outputs
  • Additional Split mode (channel 1 assigns signal to both XLR outputs)
  • Ultra-flat frequency response due to servo-balanced operation
  • Internal battery automatically shuts off when phantom power is applied
  • Allows direct connection to speaker outputs with up to 3,000 Watts
  • Ground Lift switch eliminates typical ground loop problems
  • Input 2 usable as channel 1 Link output (additional to XLR output)
  • ¼“ TRS and gold-plated XLR connectors
  • Ultra-rugged, road-suitable metal case

    They do what they say on the tin affordably.

    It's a little on the noisy side, but it's quite robust with no protruding switches and does a good job. For the money it's hard to fault.

    Ideal for Keyboards or Laptop links to the mixer MIC inputs

    The DI is being used to balance the audio signal to my video. The results are brilliant. I will also use it when I am working as a sound engineer.

    Versatile and cheap two-channel DI box, link mode turns allows you to use the second channel as a link output to feed an amp onstage or split the signal- handy for live recording. Sound quality is basic and slightly hissy, sure I've used better DI boxes but I always have one of these in my gig bag because you can never have too many DI boxes, and at the price, it's a bargain.
