JPC  Stereo PC DI Box Radial

The Radial JPC is a stereo direct box that has been specifically designed to interface computer sound cards and other consumer electronic products with professional sound systems. It is unique in that it combines the advantages of transformer-isolated inputs with an active drive circuit, giving you the ‘best of both worlds’ 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 two electrically powered devices are connected together. 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 ¼", 3.5mm and RCA input / thru-put connectors make interfacing a snap with all types of equipment. A single switch inserts a –15dB pad into both channels, two power LEDs (one for each channel) confirm 48V phantom is turned on, and a pair of XLR output connectors round out the feature set.

Hybrid circuit for low noise

The JPC is a stereo direct box that is easy to use with practically any consumer electronic device. It utilizes active buffers and transformer isolation to create a hybrid circuit that blocks ground loops and reduces system noise, along with AC blocking capacitors to prevent any audio system noise from bleeding back into the computer. The choice of ¼", RCA and 3.5mm input connectors make it easy to interface with all types of unbalanced audio sources such as computers, smartphones, and tablets, and the outputs are XLR balanced mic level to feed snake systems and PAs. Powering the JPC is accomplished via 48V phantom from a mixing console, allowing the JPC to be used in concert environments without requiring an external power supply.

Using the JPC with a computer

Computers are often the cause of noise in the PA system. The JPC's combination of transformer isolation with an active drive circuit helps reduce noise by eliminating stray currents.

Using the JPC with a DJ setup

The JPC is well suited to handle the type of audio generated by CDs and digital audio files. By isolating the the source with the PA system you also eliminate noisy ground loops.

Using the JPC with a phone

The JPC's 3.5mm (1/8") TRS jack makes it easy to interface portable playback devices. This makes it easy to bring unbalanced audio tracks into the PA system via the balanced mic input of a console.
