  • "The JD7 proved to be a real asset during the recording and the best part was that my tone and the guitar's response remained true. I purchased it after we were done!"

  • "The Radial JD7 is phenomenal! I have been looking for something like that since the sixties. The Drag control is very useful in the way it can be used to sweeten the sound and make the input very attack sensitive. A great piece of gear for a guy who likes to use multiple amps."

  • "Before we bought the Radial JD7, each time I added an amp the impedance changed, the level dropped and it messed with my tone. With it, I can run as many amps as I like. The Radial JD7 is phenomenal."

Part No. R800 7000

  • 100% discrete class-A buffers with Jensen Transformer isolation
  • Built-in Radial DI with multi-out Reamping™ capabilities

Radial JD6 Six-Channel Rackmount DI

The Radial JD7 Injector is a guitar signal splitter that is able to drive as many as seven amplifiers at the same time and do so without the noise that often plagues most systems.

It features A or B selectable inputs with Radial's award winning class-A buffering circuit for ultra low distortion. To ensure maximum signal fidelity, Drag Control™ load correction lets you replicate the load on the guitar pickup as if connected to a tube amplifier for the most natural tone. The hi-Z outputs are equipped with high-performance Jensen Transformers for optimal signal transfer. Transformer isolation along with individual ground lifts help eliminate hum and buzz caused by ground loops for cleaner, quieter guitar tracks. 180º polarity reverse ensures all amps play in phase while channels 5 and 6 are equipped with effects loops for greater setup flexibility.

The JD7 is fully equipped for Reamping: a built-in Radial direct box lets you record a dry track while a separate Reamp™ input is ready for re-recording dry tracks when needed. This enables you to move mics around the room, change amps or add effects to optimize the sound of the recording. And Reamping works equally well on bass, voice and other instruments.

Designed to spur on creativity, the JD7 is plug & play easy to use, super quiet, and amazingly natural sounding… a guitarist's dream come true and a producer's very best friend.

JD7 Injector™ - Applications
Using the JD7 as a splitter
The JD7 is equipped with A or B inputs and 6 guitar outs on the front panel plus a tuner out on the rear. Use ch-1 with a properly grounded amp, then add as many as you like. All outputs are isolated to eliminate hum and buzz.

Using the JD7 for Reamping
Start by recording a dry track using the JD7's DI output. Then send the clean track back to the Radial JD7's rear panel XLR input. Adjust the level and you are now set to drive as many amps as you need. Move the mics, change the tone settings.
Using the JD7 with effects
A great way to quiet down noisy guitars is to run all your signals through the JD7. The high performance class-A buffers and Jensen transformer isolated outputs are truly amazing! Channels 5 and 6 are also equipped with effects loops.
