Radial JD6

• 6 discrete Radial JDI DI's in a one RU 19" unit 

• Jensen® transformer equipped • Exceptionally low distortion 

• High level handling 

• Front and back connections 

• Optional hook-up extension panels The Radial JD6 6 channel direct box has been optimized for use in professional touring applications. Featuring the same highly acclaimed Jensen® transformer equipped circuit as used in the renowned Radial JDI direct box, the JD6 contains 6 completely independent audio channels for 100% isolation, minimal crosstalk and low noise. 

The Radial JD6 is ideally suited for keyboards, electronic drums and audio-visual systems in both live touring and recording environments.

Featuring the same highly acclaimed Jensen® transformer equipped circuit as used in the renowned Radial JDI direct box, the JD6 contains 6 completely independent audio channels for 100% isolation, minimal crosstalk and low noise. The Radial JD6 is ideally suited for keyboards, electronic drums and audio-visual systems in both live touring and recording environments.


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 true linear performance from 20Hz up.

In an effort to keep the front of the rack clear of obstructions, all primary connections are done on the rear panel. The Radial JD6 rear panel is ‘maxed out’ with ¼” input & thru-put connectors; XLR output for each channel; and individual channel identification. 
A choice of extension panels is also available from Radial that can bring ¼” and XLR connectors to the front or back of dual-rail 19” rack enclosures. Radial offers a choice of multi-pin quick-disconnect connectors for touring professionals. These may be configured to mate directly to Radial concert snake systems or to other manufactuer's snakes by contacting the Radial Custom Shop.
The front panel RCA jacks are also mounted adjacent to each other so that when in use, cables are brought to a single point. This keeps front panel controls clear from obstructions and makes trouble shooting and system set-ups easy.

A well-grounded individual
In today’s complex touring environments, noise is an ever-present problem. This is amplified with the fan’s expectations for quality and the improved fidelity of the sound systems in general.

To eliminate noise, every precaution has been designed in to the JD6. Take off the cover and one immediately notices the full metal shielded transformers and full-surface ground planes across the dual-sided PC board. This technology guides stray magnetic fields and radio frequencies away from the audio path.

The JD6 employs six Jensen Transformers in a floating configuration with insulated connectors for 100% isolation. A series of internal switches allow the engineer to connect each ground to the JD6 chassis for alternate ground schemes. These may then be grounded to the rack rail via a rear-panel ground lug. For those that prefer a common ground to a single channel, a side-access ground switch connects the chassis to channel-1 ground.

Built like a tank
As with all Radial products, the JD6 is built to handle the abuses of the road. A durable baked enamel finish protects the exterior and welded 14-guage steel chassis reduces opportunity for stress on the PC board and avoids the potential for cold solder joints, the No.1 cause of system failure. Radial stands behind each JD6 with a 3 year limited warrany.
