The ProRMP from Radial Engineering is a passive re-amping device that allows an engineer or producer to take a pre-recorded guitar track that would typically be at line level, and output a guitar level signal that can then be sent back to an amplifier/speaker or an effects box. This opens the door to explore new musical sounds and spur on the creative process since the unit will drive a guitar amplifier as if the player was still plugged into it.
Operation of the unit is easy. Once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. The dry recorded track is fed into the ProRMP and the output returned to a guitar amplifier or effects pedal. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording.
For the live performer, the unit provides the impetus to record a second, dry track for future editing. Fixing an effects laden track is near impossible even in the best editors, while fixing a dry signal is easy. The edit is then re-amped through the original guitar/effects chain and dropped back into the original track.
