The Radial JPC Computer Direct Box is a compact yet powerful device designed to easily interface your equipment with a PC while maintaining exceptional sonic performance. It eliminates the hum and buzz commonly associated with computers and offers a versatile array of connectivity options, including RCA and 1/4 sockets. This allows for simple interfacing with samplers, drum machines, keyboards, media players, and more.
The JPC features a switchable -10dB pad that allows you to reduce the input level from extra-loud sources to prevent overload distortion. It also has active buffers combined with transformer isolation, creating a highly-effective hybrid circuit design. The JPC is built with Radial’s phenomenal quality, with its 14-gauge steel I-beam chassis and outer shell providing excellent protection for the internal components. The unique book-end design of the JPC protects its sockets and switches, making it road-ready for various applications.
