Radial Engineering

The X-Amp from Radial Engineering is an active re-amping device that allows an engineer or producer to take a pre-recorded guitar track that would be typically 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.

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. This 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 or producer to make artistic decisions as the recording progresses.

The X-Amp employs a Class-A circuit design that has been optimized for use with guitars. Features include balanced line level input with LED peak indicator and level control, direct and isolated guitar amplifier outputs, 180° polarity reverse to bring both amps into phase and dual ground lift options for noise-free operation. 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.
