QUESTIONS & ANSWERS

Ask a Question
  • Since it is passive, can I use this device backwards to convert a balanced mono signal from a mixer board to an unbalanced mono signal for input to a streaming box?

    The Device can not be used as backward to convert the balanced signal to unbalanced

  • Can I use this device to reduce a line level output (from my headphone out jack on an audio amp) to a mic level, which I will use as an input to my USB audio interface at a much lower (undistorted) level? Do I plug the line level source into the balanced XLR port as an input, and use the PARPOUT 1/4" jack output as the input for my audio interface? Would plan to attenuate signal by -40dB for testing. Thanks for your help!

    This device allows a line-level source to be plugged into a mic level input. Para Out is a Passthrough Output

  • My mixing console has global phantom power. Is it safe to plug this in and will it protect my instrument from the phantom power?

    Yes, it is perfectly fine to have a passive DI box with phantom power turned ona properly designed passive DI will not be affected by phantom power as it functions solely through a transformer, which prevents any current from flowing through it from the phantom power source. 

  • Can use with headphones

    No.
