From Radial Engineering

  • Six channel rack DI for live stage and studio
  • Jensen transformers add warmth to digital sources
  • Handles high signal levels without distortion
  • Front and rear panel connectivity for added routing options

The Radial JD6 is a high performance 6-channel rackmount direct box designed for the most demanding studio and live touring applications. Stemming from the industry standard Radial JDI, the JD6 incorporates six top-of-the-line Jensen audio transformers with extra RF filtering to ensure optimal signal transfer without noise, distortion or artifact of any kind.

Jensen transformers are legendary in their ability to withstand extreme signal levels without choking. This makes the JD6 particularly effective when managing high output active devices such as digital pianos that will often overload most direct boxes or preamps. The passive design further benefits due to its ability to provide galvanic isolation from the input to the output, thus eliminating the hum and buzz that is often encountered due to ground loops and DC current offsets. This makes the JD6 particularly effective for use with keyboards, drum machines, electronic drums and audio sources such as CD players or computers.

Each JD6 channel is equipped with a rear-mounted ¼" instrument input and thru-put for the artist's amp plus a lo-Z balanced mic level XLR output to feed the mixing desk. The front panel presents an ergonomically efficient array of switches and connectors including ground lift, 180º polarity reverse, stereo to mono merge plus a low-pass filter to reduce unwanted high frequency noise that is common with older vintage keyboards. Channels 1 and 2 are supplemented with front panel 'priority' connectors for improved efficiency.

These features combine to present a true 'Swiss army knife' of options making the Radial JD6 the finest rack DI made today.

The Radial JD6 is a multi-channel passive direct box that has been specifically designed to address the needs of concert touring, while being equally at home in the studio. The JD6 houses six completely independent Jensen® transformer isolated channels for minimal cross-talk and maximum protection against noise, 60 cycle hum, and buzz. Jensen® transformers are legendary in their ability to reject noise caused by RF, magnetic induction, and 'ground loops' while producing an exceptionally wide bandwidth and warm Bessel response. The JD6 employs the same audio circuit as the renowned Radial JDI for explosive signal handling, virtually zero phase distortion, and a truly linear response.
