$ 129.99 $ 156.00
Passive Direct Box
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.
- Compact passive direct box for stage and studio
- Able to handle huge transients without distortion
- Transformer isolation eliminates noisy ground loops
- Plug and play easy to use feature set – on stage or in the studio
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.
