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.
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 140k? 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.
