Active DI, stereo inputs for laptops & CD players, phantom powered. 

The JPC from Radial Engineering is a stereo direct box that has been specifically designed for connecting computer sound cards and other consumer electronic products to a professional sound system. It combines the advantages of transformer-isolated inputs with an active drive circuit.

Transformer coupled inputs isolate the source from the destination. This eliminates 60-cycle hum and buzz. Because the active circuit does all of the impedance conversion and balancing, a dedicated 1:1 transformer can be used. This results in a hybrid design that is at once great sounding, compact and affordable.

The book-cover wrap-around sleeve design protects switches and connectors from damage while the 14 gauge steel I-beam construction eliminates stress that could torque the PC board and cause solder joint failure. A full-bottom no-slip pad provides electrical insulation and mechanical isolation.
