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

- Minimal product documentation from the manufacturer makes setup less intuitive for first-time re-amping users
Frequently Asked Questions
What does the EXTC Stereo actually do in a recording workflow?
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.
Can I use mono effects pedals with the EXTC 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.
Does the EXTC Stereo require external power?
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.
Is this device suitable for live performance or only studio use?
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.
