Radial Passive Reamper with Custom Transformer and Level Control

The Radial ProRMP Reamp Box is a transformer-coupled passive device designed to convert balanced line-level signals to match the high input impedance of a guitar amplifier. Ideal for reamping and warming the balanced output of a wireless system, the ProRMP ensures excellent performance with low distortion and a wide frequency response. Its passive design means it requires no external power, making it a convenient and reliable tool for studio and live applications.
