Reamping made simple. The Radial ProRMP Studio Reamper is a 100% passive Reamper and does not require any external powering. The magic behind the ProRMPs great tone is a custom wound transformer that converts the balanced line level source to a hi-z output for your amp whilst acting as an electrical isolator- eliminating troublesome ground loops that can often cause buzz and hum in the sound. Extremely easy to use the ProRMP connects from the recorder to your amp and effects units performing all required impedance matching for you. Just adjust the level to suit! The ProRMP is built tough encased in 14 gauge steel housing with a I-beam frame that protects all internal circuitry from damage. A full-bottom no-slip pad provides plenty of stay put while also electrically isolating further reducing any unwanted noise caused by ground caused by ground loops.
