Radial ProRMP Passive Reamper with Custom Transformer

Studio Reamper

For years, Reamping has been the secret weapon for countless recordings by the biggest names in the business! Few realize that recording engineers not only Reamp guitars, but often Reamp bass, keyboards, drums, and even voice as a means to bring creative new tones and sonic signatures to their music.

Reamping for every studio

The Radial ProRMP is a 100% passive Reamper. This means it does not require any external powering. The magic behind the ProRMP's great tone is a custom wound transformer that at once converts the balanced line level source to a hi-z output for your amp while also acting as an electrical isolator to eliminate troublesome ground loops that can often cause buzz and hum in the sound. Plug and play easy to use, the ProRMP connects from the recorder to your amp and effects units and does all the impedance matching for you. Just adjust the level to suit!

Reamping Step-1

Record the guitar track using a Radial direct box like the Pro48. This splits the signal so that the guitar player can hear his amp while you capture the clean (dry) performance.

Reamping Step-2

Send the dry track from your recording system to the ProRMP. This then feeds your guitar amp and pedals. Adjust the tone and move the mics until you get the sound you want.

Using the ProRMP with a wireless system

Most wireless systems simply do not sound all that good. Take the balanced output from the wireless and send it through the ProRMP. You will be amazed at the warmth!

Play pre-recorded tracks through amps and pedals.

On board level control for fine tuning amp level.
