Radial Engineering ProRMP 1-Channel Passive Reamper - Studio Tone Sculpting

The Radial Engineering ProRMP is a compact, passive reamper that transforms pre-recorded tracks into fresh tones by sending balanced line-level signals through guitar amps, effects pedals, or other gear. Featuring a custom-wound transformer, it converts low-impedance line signals to high-impedance instrument level while eliminating ground loops and hum, preserving pristine audio without amplification or batteries. Ideal for exploring reamping techniques, the ProRMP delivers smooth, natural sound with minimal phase distortion, making it a studio staple for producers seeking creative textures and tones.

Custom Transformer Performance

The ProRMP's custom-wound transformer acts as both a signal converter and isolator, providing ruler-flat frequency response and low distortion for accurate reamping. It handles professional +4 dB line levels, smoothing transients while retaining the source's character, perfect for guitars, bass, keyboards, and percussion in DAW-based workflows.
