Re-amp your tracks with Radial!

The Radial ProRMP is a passive box that allows for re-amping of the signal. Re-amping has been the 'secret weapon' for countless recordings by the biggest names in the business and the process is often used on guitars, bass, keyboards, percussion and even voice to create new textures! The ProRMP is a 100% passive re-amplifier that lets you to take a pre-recorded track and re-amplify it through a guitar amp or effects pedals to create new and exciting tones. Dive into the creative possibilities of re-amping with the ProRMP.

  • Built tough
  • In use

Easy to use
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!

Custom-wound transformer
The magic behind the ProRMP's great tone is a custom wound transformer that at once converts the balanced low-z source to a hi-z input 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.

Built tough
Like all Radial products, the ProRMP is built tough! Encased in a 14-gauge steel, the ProRMP employs a unique book-end design with a welded I-beam frame that protects it from damage and assures the PC board and solder points will not be stressed, adding durability. A full-bottom no-slip pad works double duty by providing plenty of stay put while also eliminating electrical contact points from guitar amp chassis bolts that could cause ground loops.

In use
Plug a standard balanced cable from your recorder or mixer output to the ProRMP's XLR input. Connect the 1/4" ProRMP output to your instrument amp. Adjust the ProRMP's output level control as required to match the amp input and engage the ground lift switch to eliminate any hum and buzz caused by ground loops.

Does the job perfectly

Once again TJ came through with a solution for me. I like to practice bass with headphones (thx TJ) on, while listening to tracks from my iPhone, mixed through my Allen & Heath mixer (thx again TJ) with an XLR Bluetooth receiver picking up the iPhone signal (thx again TJ). But…sometimes I like to practice with the phones off. The ReAmp sends a noiseless signal from the mixer to my bass amp so I can hear everything from the mix in the room. Stellar service from Sweetwater once again!
by Stan from St. Augustine FL on

fun for even drummers!

Took a few to get the routing correct, but thanks to Roq who helped via many emails and phone calls, this reamp box helped link up some pedals to effect some prerecorded drums. Roq was super patient and extremely helpful, and now my studio has a whole additional level of vibes.

Great Little Re-Amper

It does the job it's designed to do, sounds great and isn't overly expensive. What's not to like?
by Lester Holman from Memphis, TN on

Perfect tool for the job.

This thing is small, simple, and weighs about what a brick does. I got it, plugged it in with a TRS to Male XLR cable (don't forget the cables), patched it through to my interface on one side and out to a TC Electronic Plethora x5, then back into my interface. My DAW of choice is Studio One, so I dropped Pipeline XT (the outboard FX sync plugin native to Studio One), synced it up and started recording. I only have one of the Reamp boxes so far so I'm going into the Plethora x5 Mono and coming out Stereo.

I recorded a pair of tracks through the Helix Phaser, a pair through the Mimiq Doubler, then a pair through an insane reverb (all effects in the TC Plethora), then mixed the resulting tracks in the DAW. I know this sounds like a review of the Plethora, and in a sense it is (get one), but the tool that made it easy to use my effects pedal outboard with my DAW is the Radial PRO-RMP. Without it I'm limited to plugin's in the DAW and line level outboard tools like compressors and EQ's. This is the coolest. Being able to dial in a sound and record is like live recording. Granted, I can dial it back in the mix by mixing with the original track, but there's something really awesome about being able to touch a real knob and get an effect the way I want, then lock it in.

Whether you are going out to an amp or effects, this is a great tool. The signal is clean. The box is solid steel (I seriously think I could drive a truck over it and never lose signal). and the setup couldn't be more simple. I'm getting another one so I can go out stereo as needed.

Now, for the other thing. I don't do this often, but it's time for me to address the elephant in the room. I love this tool, but I likely would have waited a while to get one if I had been dealing with any other store than Sweetwater. These are the guys I call when I think I'm on the right path, but I'm not sure. They always have good advice, and have never steered me wrong. This is a great tool for me. If you're still not sure, call your Sweetwater rep and see what he or she has to say. You may have an interface that can't take instrument level back in and you'll need one of the active boxes. No worries; talk to your rep. Either way, if you're looking for a reamp box, you can't go wrong with Radial and Sweetwater.

Perfect solution

I got this reamping box in a pinch, during a session. It saved my behind! My guitar recordings have come out so much better, not that I can take the time to perform a clean direct performance, at any hour of the day. I can test multiple amps on multiple takes, I could go on listing the benefits. If you don't have a reamping box, you should definitely look into it as a guitarist/bassist !!
