Description

The Radial EXTC Stereo bridges the gap between guitar-pedal effects and professional line-level gear, letting you wire stompboxes directly into your mixing console or recording interface. Instead of effects being limited to instrument-level signals, this box handles the level conversion both ways, so pedals built for guitars can process any signal in your session.

Mix engineers use it as a workaround for expensive rack effects: run drum overheads through a multi-tap delay pedal, drop a chorus or flanger on a flat-sounding keyboard part, or send vocals and strings through a reverb stomp box for texture you won’t get from plugins. Because it’s stereo, both channels stay linked for effects like ping-pong delays or stereo modulation, keeping the width and imaging intact.

Connects stereo guitar pedals to balanced, line-level recording equipment
Front-panel 1/4″ inputs and outputs make patching pedals in and out fast
Send and Receive controls let you dial in proper gain staging on each side
Gives dormant pedal collections a real job in the mix, not just on the guitar rig

If you’ve got a box of pedals gathering dust, the EXTC Stereo is the missing link that puts them back to work behind the console.
