The Radial Engineering ProRMP is a 100% passive Reamper. This means it does not require any external powering. The magic behind the Radial Engineering ProRMP's great tone is a custom wound transformer that at once converts the balanced line level source to a hi-z output for your amp while also acting as an electrical isolator to eliminate troublesome ground loops that can often cause buzz and hum in the sound.

Plug and play easy to use, the Radial Engineering ProRMP connects from the recorder to your amp and effects units and does all the impedance matching for you. Just adjust the level to suit!

Like all Radial products, the Radial Engineering ProRMP is built tough! Encased in 14 gauge steel, the ProRMP employs a unique book-end™ design with a tough I-beam frame that protects it from damage and assures the PC board and solder points will not be stressed.A full-bottom no-slip pad works double duty by providing plenty of stay put while also eliminating electrical contact points from guitar amp chassis bolts that could cause ground loops.
