Radial Engineering ProRMP Reamp Box – Passive Re-Amplification Interface for Re-Recording and Guitar Amp Signal Processing

The Radial Engineering ProRMP Reamp Box is a professional passive re-amplification interface designed to send previously recorded audio tracks back through guitar amplifiers, pedals, and analog effects chains for creative re-recording and tone shaping.

Built around a high-quality custom transformer, the ProRMP converts balanced line-level signals from a recording interface or DAW into a high-impedance, unbalanced instrument-level signal that behaves exactly like a real guitar output. This allows engineers and musicians to “replay” clean DI recordings through amps and stompboxes as if the instrument were being performed live.

Because it is a fully passive design, the ProRMP requires no power and delivers extremely transparent signal conversion with minimal noise and distortion. The transformer also provides natural isolation, helping eliminate ground loops and ensuring clean operation when connected to studio gear.

A dedicated level control knob allows precise adjustment of output signal strength, making it easy to match the input sensitivity of different amplifiers and effects pedals. This gives full control over how the reamped signal interacts with the gear, from subtle tonal coloration to heavy distortion shaping.

Key Features:

• Passive re-amping interface for studio recording and tone shaping
• Custom Radial transformer for clean signal conversion and isolation
• Converts balanced line-level signal to high-impedance instrument signal
• Level control for precise output adjustment to amps and pedals
• No power required (fully passive operation)
• Eliminates ground loops and reduces noise in reamp setups
• Ideal for guitar, bass, and creative sound design workflows
