The Radial JDV is more than a direct box. It is a dual input DI box, mic preamp, two-channel 

mixer and phase adjustment tool all in one. This means it can be used for all types of instru-

ments including:

What is particularly cool about the JDV is that it packs all of this in a relatively small box. 

This means that you have to start by understanding the many features and then apply them 

according to how you intend to use it. 

There are two inputs and one output. You can set each input to suit a particular instrument 

and then send the unbalanced output to a stage amp, while sending the balanced signal to a 

recording workstation or PA system. You can switch between the inputs using the front panel 

switch or via an optional remote footswitch. You also have the option of blending both chan-

nels together so that they play simultaneously. 

•  Passive electric bass with magnetic pickup

•  Active electric bass with built-in preamp

•  Acoustic guitar with built-in preamp

•  Piezo equipped upright bass

•  As a microphone preamp for an instrument mounted mic

•  For direct recording or live performance

•  Any combination thereof
