Radial Engineering JD6 Six-Channel Passive Direct Box with Multi-Channel Signal Distribution and Transformer-Isolated Outputs

The Radial Engineering JD6 is a professional 6-channel passive direct box designed for high-density signal distribution in live sound, studio, and installed audio environments. Housed in a 1RU 19-inch rackmount chassis, it provides a compact and efficient solution for converting multiple unbalanced instrument or line-level signals into balanced, low-noise outputs.

Each channel features high-quality transformer isolation, helping eliminate ground loops, reduce hum, and maintain clean signal integrity across long cable runs. This makes the JD6 ideal for keyboards, synthesizers, playback devices, and multi-output electronic instruments commonly used in modern production setups.

The unit includes both 1/4” TRS and RCA inputs, offering flexible connectivity for a wide range of audio sources. Its fully passive design requires no external power, ensuring reliable operation in any environment while simplifying setup and reducing potential points of failure.

Built with a rugged steel chassis and designed for professional touring and installation use, the JD6 delivers consistent, transparent performance even in demanding multi-channel applications.
