Radial ProDI Passive Direct Box

The ProDI™ is a passive direct box that combines exceptional audio performance with solid dependable construction, making it the ideal general duty direct box for stage and studio.

The ProDI is a passive direct box designed for use on stage or in home recording studios, with the ability to handle high output instruments without distortion, and a transformer-isolated output to eliminate noise from ground loops.

Following the footsteps of the Radial JDI, the ProDI is a high-quality ultra-compact passive direct  box  that  has  been  specifically  developed  to  allow  regional  sound  companies  and project studios to enjoy the quality of a Radial direct box at a more affordable price point. The  ProDI  features  a  custom-made  transformer  that  is  able  to  handle  high  levels  without saturation.

World class DI

The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140kΩ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal MuMETAL® shield to protect against electromagnetic fields that can cause unshielded transformers to distort.

This   high-performance   transformer   has   an   exceptionally   linear   frequency response from 20Hz to 18kHz, making it ideal for electronic musical instruments and audio equipment.  The  ProDI  also  features  a  -15dB  PAD  for  high  output  sources  and  ground  lift switch  to  troubleshoot  noise  from  ground  loops. The  ProDI  is  a  great  choice  for  bass  and acoustic guitar.

ProD2 stereo version is also available. The ProD2 is essentially two ProDI’s in one compact enclosure  designed  for  stereo  keyboards,  DJ  equipment  and  consumer  hi-fi   systems. The ProDI and ProD2 are housed in an extremely rugged two piece 14 gauge steel enclosure with a book-end-designed outer shell that prevents damage to the switches.

Pro DI Applications:

ProDI with electric bass

The ProDI works great for high output devices like active bass guitars. It's able to handle the huge signal levels from active pickups without distortion and the transformer isolation prevents ground loop hum. The ProDI sends the pure sound of the bass to the PA and to the player's amp

ProDI with acoustic guitar

Acoustic guitars can sometimes have sharp sounding active preamps. The ProDI naturally smoothes out the transients for a warmer tone. And because the ProDI is able to handle loud signals from active pickups, it will not distort. This makes it a great direct box for acoustic guitars.
