Balanced interface for guitar effects pedals
With the Radial EXTC, you can easily tap into the wild world of effects pedals at any phase of the recording process, while maintaining the signal quality your professional recording rig demands. Just connect a line-level audio signal, then let the EXTC work its magic. The EXTC will convert to a hi-Z signal, so you can patch in any stompboxes you want via 1/4" send and receive connectors on the front panel. Send and Receive knobs are there for setting levels, while a blend control lets you attain just the right amount of the effect.

Optimized signal path preserves your sound quality
Radial built the EXTC with signal integrity chiefly in mind, opening up the doors to creative stompbox use beyond just lo-fi applications. The EXTC includes Radial’s award-winning, fully discrete Class A guitar buffering as well as transformer isolation to eliminate ground loop buzz and hum. There’s also a 180º polarity reverse to keep your effects and balanced signals in phase.

Convenient 500 Series format
Canada-based Radial Engineering has embraced the 500 Series format, contributing a range of excellent-sounding (and exceptionally made) tonal tools and sonic options to the popular modular format. The EXTC is another fine example of Radial at its best, ready to go in any 500 Series compatible rack.
