Overview

The Radial Engineering EXTC Stereo is an active re-amping device built for a specific and powerful studio technique: routing recorded tracks from your DAW through external guitar and bass effects pedals, then capturing the processed result back into your session. It takes balanced line-level signals and converts them down to the unbalanced instrument-level that effects pedals expect, with a variable output control to dial in the right drive level for each pedal. After the signal passes through your pedal chain, the EXTC Stereo converts it back to balanced line-level for clean return to your audio interface or console.

What sets the EXTC Stereo apart from basic re-amping boxes is its stereo configuration, which allows you to run two independent or stereo-linked effects loops simultaneously. This opens up creative possibilities such as processing a synth pad through two different delay pedals panned left and right, or running a vocal through stereo chorus and reverb pedals to create lush spatial effects that plugins may not replicate with the same character. Radial Engineering's active circuitry ensures minimal noise and signal degradation throughout the conversion process, maintaining the audio quality that professional mixing demands.

Pros & Cons

👍 Pros

  • Enables creative use of guitar and bass effects pedals on any recorded track during mixing
  • Stereo send/return loop preserves stereo imaging when processing through two effects simultaneously
  • Active circuitry from Radial Engineering ensures clean signal conversion between line and instrument levels
  • Compact and straightforward design integrates easily into existing studio patching setups

👎 Cons

  • Requires an external 15V power supply, adding another cable to manage in the studio
  • Limited to re-amping through effects pedals — does not include amp simulation or DI functionality on its own
  • Premium price point compared to passive re-amping boxes that handle basic mono conversion
  • Minimal product documentation from the manufacturer makes setup less intuitive for first-time re-amping users

Frequently Asked Questions

It converts balanced line-level signals from your DAW or mixer down to instrument-level so you can send them through guitar and bass effects pedals, then converts the processed signal back to line-level for return to your DAW — all in stereo.
Yes. While the unit is designed for stereo operation with two send/return loops, you can use it with mono pedals on one or both channels depending on your routing needs.
Yes. It operates on a 15V power supply drawing 300 milliamps. It is a corded electric device and does not run on batteries or phantom power.
The EXTC Stereo is primarily designed for studio recording and mixing workflows where you want to integrate effects pedals into your signal chain via a DAW. It can be used in live settings, but its strength is in controlled studio re-amping applications.
