Active Direct Box for Laptop Computers
The Radial JPC is an analog stereo interface professionally designed to help solving the hum and buzz problems that is commonly associated with connecting a computer or consumer playback device to an audio system.
The Radial JPC is a stereo consumer to mic level interface capable of offering a myriad of input connector options to simplify for interfacing your computer, MP3 player, DVD/CD or other consumer audio device with the world of balanced professional audio equipment. As with all Radial products, tremendous attention has been paid to quality construction and capable to deliver exceptional audio performance and eliminating noise at the same time.
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.
