About this item
Product Highlights
Pyle PDC21 is a necessity if you are looking for the higest quality of sound, with low distortion, noise, and eliminate ground loops. A DI unit, DI box, Direct Box, Direct Input, Direct Injection or simply DI is an electronic device that connects a high impedance, line level, unbalanced output signal to a low impedance mic level balanced input, usually via XLR connector. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input. The DI performs level matching, balancing, and either active buffering or passive impedance bridging to minimise noise, distortion, and ground loops. DIs do not perform impedance matching. Pyle has been in business for over 35 years, and their manufacturing experience and expertise is easy to see - and hear.

Questions & Answers
QUESTIONS & ANSWERS
Ask a Question
Cancel
- 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 on; a 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.
