A stereo direct box that has been specifically designed for use with computer sound cards
The Radial Engineering JPC stereo PC direct box is specifically designed to connect computer sound cards and other consumer electronic products to professional sound systems. The JPC stereo DI box combines the advantages of transformer-isolated inputs with an active drive circuit, giving you the best of both in a compact and extremely flexible package.
Transformer coupled inputs have the unique advantage of isolating the source from the destination. This proven approach eliminates 60-cycle hum and buzz caused by ground loops when 2 electrically powered devices are connected. 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 more affordable.
As with all great designs, simplicity is a fundamental trait and the Radial JPC certainly fits the bill. A choice of stereo Â¼", 1/8" and RCA input AND thru-put connectors make interfacing a snap with all types of equipment. A single switch inserts a -10dB pad, two power LEDs confirm 48V phantom is turned on, and a pair of XLR output connectors round out the feature set.
Of course, like all Radial products, the JPC stereo direct box is built to handle any audio environment. The book-cover wrap-around sleeve 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 with plenty of 'stay-put' for use on hectic stages. And with its baked enamel finish, the Radial JPC DI Box will continue looking great for years!
