• Extraordinary level handling without distortion
• Built to survive the road
The Radial JD6 is a six channel, rackmount direct box designed for keyboards and electronic
drums for both live and recording environments. The JD6 is equipped with custom Radial
Eclipse transformers for maximum headroom and low phase distortion to render the most
natural sound. This is of particular importance for digital pianos that are both extremely dynamic
and have tremendous harmonic content.
All standard controls are front-panel mounted for easy access, and include pad, polarity reverse
and ground lifts. Channels 1 & 2 are further equipped with switching jacks that provide front
panel priority over the paralleled rear connectors, providing studio patch-bay functionality. An
innovative stereo to mono merge function with ¼” and RCA connectors to enhance connectivity ,
while passive fi lters may be used to reduce noise. Inside, a second series of grounding switches
allow the system designer to adapt the JD6 to suit his specifi c grounding scheme.
In an effort to eliminate hum & buzz caused by ground loops, all six channels are completely
independent and transformer-isolated, making the JD6 a wonderful problem-solver for the most
demanding professional applications.
