Radial JDV 500-Series Active Direct Box

The Radial JDV 500-Series Active Direct Box is a 100% discreet class-A instrument direct box with a unique feed-forward design that does not employ any form of traditional negative feedback phase cancellation techniques whatsoever to stabilize the input circuit. This innovative design captures the very essence of instrument and delivers the natural tone without artifact.

The Radial JDV 500-Series Active Direct Box is equipped with instrument input plus a buffered thru-put that can be used to drive 50 feet of high-Z cable to the amplifier. Radial's innovative Drag Control load correction allows the user to apply the desired load on the pickup for the most natural rendering. This can be bypassed for a 4 meg-ohm input for finicky piezo pickups.

The Radial JDV is augmented with an adjustable high-pass filter designed to remove low-end resonance to help clean up the mix. The Radial JDV Omniport is set up as a hi-Z output to drive a tuner, a second amplifier or effects.

This makes the Radial JDV the ideal front end interface for bass guitar, acoustics and any other direct to recorder instrument you may encounter.
