The Radial JPC is a stereo direct box that has been specifi cally designed for use with
computer sound cards and consumer electronic products. Flexible inputs, transformer
isolation, active drive circuits and heavy-duty construction make the JPC ideal to interface
consumer line-level signals to professional sound systems.
Connecting the JPC is easy. A full array of RCA, 3.5mm and 1/4” stereo connectors,
commonly found on CD players, VCRs and notebook computers, are provided. For more
connecting fl exibility, any of the JPC inputs can serve as thru-puts, providing a convenient
way to split the signal.
Hybrid design offers the best of both active and passive worlds. Dual passive transformers
at the input provide 100% isolation to eliminate buzz & hum caused by ground loops.
Following the transformers, the JPC uses an active drive circuit powered by 48V phantom.
The active drivers perform impedance conversion and signal balancing, allowing the JPC
to drive long cable runs. Finally, the JPC is packaged in an innovative and tough 14 gauge
steel welded I-beam enclosure that makes it impossible to torque the PC board. The JPC
offers a compact, rugged, easy-to-use, fl exible solution for interfacing audio/video
equipment on the stage or in the studio. And it sounds great too!
