Radial JPC Computer Direct Box 



  • Description

Radial JPC Computer Direct Box  


Computers are notorious for introducing noise into the audio signal. The Radial JPC is an analogue stereo interface that combines active buffers and transformer isolation to help solve the buzz and hum problems you’ve experienced when connecting a computer to an audio system. Whew … finally.


Intended for professional field use, the JPC offers a choice of 1/4", RCA and 3.5mm input connectors to accommodate all types of unbalanced audio sources (such as computers, iPods, and CD players). Isolation transformers eliminate hum and buzz, and reduce system noise caused by ground loops. AC blocking capacitors prevent pollution from the audio system from bleeding back into the computer. 


Outputs are XLR balanced mic level for easy interface to snake systems and PAs. Powering is furnished by 48V phantom from a mixing console, eliminating the need for an external power supply.



  • Stereo phantom powered direct box for computers
  • Easy to use stereo interface for laptop computers 
  • Active signal path with transformer isolation
  • Eliminates hum and buzz common to PCs
  • Full connector options set for easy interface

Why we like it:

Face it: The computer and the PA are not always friends. With the Radial JPC, it sounds like they may be getting along after all. And like everything from Radial, it’s built for the long haul.


If it says Radial, we know it’s well engineered and built to last. There’s less-expensive gear out there, but none better. Radial gear performs gig after gig, session after session, and you can expect years of service—which means our customers love them and we don’t see them coming back for repairs. We always like that.
