Radial JPC Sound Card DI Box
The JPC is an analogue stereo interface designed to help solve the hum and buzz problems commonly associated with connecting a computer or consumer playback device to an audio system.
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.
- Easy to use stereo interface for laptop computers
- Active signal path with transformer isolation
- Eliminates hum and buzz common to PCs
- Multiple connector types for any audio source
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 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.
