Radial ProDI Passive Mono Direct Box Features Full-range, passive direct box. Used On Bass Pedal Board For A While. Lift switch lifts the ground to pin-1 on both channels. -15dB pad reduces the level going in from loud sources that could overload the circuit and cause distortion.
Radial's most popular direct boxes are known for their tremendous headroom, and the ProDI is no exception. Made to handle active electric guitars, basses, and other high-input instruments, you can count on the ProDI to withstand huge signal levels without distortion. At the core of its passive design are two high-performance Eclipse ET-DB2 transformers, which deliver a wide frequency range without distortion, even in the critical bass and mid regions. Unlike active circuits that overload when the signal gets too hot, transformers saturate the sound, creating a pleasing effect that rounds the tone and acts like a subtle limiter. The sound is further improved upon with the internal MuMETAL shield to protect against electromagnetic fields that would otherwise distort the sound. If you're a musician with a hot sound that needs to be reigned in, the ProDI will have your signal perfect for any mixing board you come across.
