Radial Engineering JD7

The Radial JD7 Injector is a class-A guitar distro/splitter with built-in Radial DI and Reamp that can drive up to seven amps or pedal chains simultaneously.

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.
