Radial's most popular direct boxes are known for their tremendous headroom, and the ProD2 is no exception. Made to handle electric keyboards and other high-input instruments, you can count on the ProD2 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. When paired with digital pianos and drum machines that produce excessive dynamics, that feature is key to always producing the perfect tone. They also also adept at eliminating hum and buzz caused by ground loops.If you're a musician with a hot sound that needs to be reigned in, the ProD2 will have your signal perfect for any mixing board you come across.
