A Great New Creative Tool Designed to Simpify Re-amping

The Radial X-Amp is an active re-amping device that lets you use a a pre-recorded track from a line level device to drive two guitar amplifiers or effect pedals simultaneously. This opens the door to explore new musical sounds and spur on the creative process. Re-amping is one of those producer's tricks for bringing new sounds and textures to already recorded tracks, and the X-Amp is designed to to the job well. This active re-amping device features a Class-A signal path, an input level overload indicator, an isolated output to get rid of ground loops, and a variable output level control. Add a new wrinkle to your recordings with the X-Amp!

Radial X-Amp at a Glance:
  • Active re-amping device
  • 100% Class-A signal path
  • Two outputs to drive two amps
  • Input level overload LED indicator
  • Isolated output eliminates ground loops
  • Variable output level control
Active re-amping device

With the X-Amp, you could for instance take a pre-recorded guitar track, and send it through a second distortion pedal and amplifier and then slightly delay the track to add a thick doubling effect. You could also use the X-Amp from a voice track to a distortion pedal to ad some grit to a performance. Another popular use would be to go back and fix a track should an error or glitch somehow appear.

100% Class-A Signal Path

The X-Amp employs a unique Class-A circuit design that has been optimized for use with guitars. Using the X-Amp is easy: One would, for instance, record a dry track using a high quality direct box, then send this track from the recorder to the X-Amp and then to either guitar amps, effect pedals or combinations thereof.

Creative Advantages

Recording using the X-Amp has many benefits: Once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording. Furthermore, by driving two amps at the same time, new sounds and textures can be created allowing the engineer - producer to make artistic decisions as the recording progresses.

Input Control and Noise-free Output

X-Amp features include balanced line level input with LED peak indicator and level control, Class-A circuit topology for optimal reach and frequency response, direct and isolated guitar amplifier outputs, 180-degree polarity reverse to bring both amps into phase, and dual ground lift options for noise-free operation.

Solid Construction:
As with all Radial products, the X-Amp is built like a tank to provide years of trouble-free performance. A welded I-beam internal skeleton provides a separate housing for maximum protection against external forces, which may cause stress on the PC board assembly while the outside bookend cover provides a protective zone for the switches, potentiometer and connectors. A full bottom no-slip pad performs double duty by keeping the X-Amp from sliding around when placed on a vibrating amplifier while also providing electrical and mechanical isolation.

Radial X-Amp Features:
  • 14-Gauge steel welded I-beam construction makes it impossible to torque the PC board.
  • Class-A active circuit for transparency and lowest possible noise.
  • Ground lift switch - recessed to prevent accidental use.
  • Audio Transformer provides 100% isolation to eliminate hum and noise caused by ground loops.
  • Heavy duty connectors and switches - high cycle for reliable performance.
  • Military spec PC board with full surface ground plane to reduce RF noise susceptibility.
  • INPUT - Balanced LINE LEVEL XLR input connector, normally connected to recorder output. A dry guitar track would be a typical source signal.
  • GROUND - INPUT SIDE lifts pin-1 ground at the XLR-in to help eliminate ground loops that can cause buzz and hum in a sound system.
  • POWER - X-Amp comes equipped with a 15VDC 400mA power supply. Optional 100V, 110V, 220V and 240V PSUs are available.
  • Full bottom rubber pad - provides plenty of stay-put wherever you place the X-Amp. Also electrical isolation from amp handles etc.
  • Book-cover design creates a protective zone around switches & connectors - Indestructible 14-gauge steel construction with baked enamel finish.
  • Power LED - lets you know the X-amp is on and ready to use.
  • LEVEL control - adjusts the X-Amp level going to your amp or effects to match that of your guitar; get the exact sound as plugging directly in!
  • CLIP LED - provides visual cue of input signal overload.
  • OUT-1-1/4" DIRECT feed from the X-Amp's Class-A circuit. This output should always be used to ensure proper grounding.
  • POLARITY - 180-degree reverse on the isolated OUT-2 to correct the phase with an amp or device connected on OUT-1.
  • OUT-2 - 1/4" ISOLATED 2nd output to another amp or effect(s). Transformer isolation eliminates the hum and buzz caused by ground loops.
  • Ground Lift switch on output - lifts ground between OUT-2 and OUT-1. Side mounted switch is recessed to prevent accidental use.
The Radial X-Amp is easy to use, loaded with features, and designed to make re-amping simple!

Works Great!

It does what it is supposed to do, and it does it very well. Having two outputs is also a nice bonus. I wish that there was an on/off switch (so that I could leave it plugged in all the time), but meh. Not a big deal.


Excellent product. Does what it says it will do.

A must have for distortion pedals for keyboards

I like to add analog grit to my synthesizers, and guitar distortion pedals can provide great sounding distortion that is much better than digital plug-ins' distortion and for reasonable costs. However, I learned that the impedance that guitar levels and keyboard line levels use do not match, so this box does the trick to match the impedance. It really sounds great, no noise, no attenuation, just free flowing signal.

A must have

A great tool for total control of your guitar sound or sound of clients that come to your studio..!! Couldnt be without it now ...!!$

Great Product.

I haven't even begun to use all the features. I'm using this straight up for Reamping and I love how I can dial in the gain of the signal before it gets to the amp in order to push the amp the way a typical guitar would. Sounds super clean and is virtually noiseless.
