The Radial Engineering ProRMP is a passive reamper built on a single premise: recorded tracks deserve a second chance through a real amplifier, and that process should be sonically transparent. Reamping — sending a previously recorded dry signal back out through an amp, pedal board, or effects chain — has been a studio production tool for decades, but doing it correctly requires proper impedance conversion. Feed a balanced line-level signal directly into a guitar amp's instrument input and you'll hear the problem immediately: it's bright, stiff, and thin, lacking the natural interaction between pickup impedance and amp input that defines guitar tone. The ProRMP uses a transformer-based design to convert your interface's balanced line output to the high-impedance instrument-level signal your amp expects, and the result is a tonally accurate reamp that sounds like the session was tracked that way from the start.
The passive circuit means the ProRMP introduces nothing extraneous to the signal path — no active components, no power supply noise, no gain stage to manage. The unit is built to Radial's standard of transformer and chassis quality: heavy, reliable, and designed to survive years of patching, travel, and session pressure. The bundle adds a 20-foot balanced XLR cable to connect your interface output to the ProRMP's input, covering the practical need of routing across a control room or into an iso space without additional sourcing. The signal path is input XLR to the ProRMP, then TS instrument cable out to the amp — the simple, direct chain that keeps reamping sessions fast and sonically honest.
