The Radial EXTC-SA is a stand-alone audio interface that lets you incorporate guitar effects into the realm of pro-audio recording. Just imagine… add a touch of grit to a vocal track, some wah on a kick drum, maybe flange a violin…The EXTC is a creative tool made for your esoteric-inventive side, ready to unleash fresh new sounds that will make your recordings stand out from the crowd.

And it's super easy to use: connect a line level signal from the recording system. The EXTC-SA unbalances the signal and converts it to high impedance where guitar pedals can be inserted at will. Simply plug in, turn the track on, set your levels and adjust the blend for just the right amount of magic. Be prepared for instant amazement. Legalized ecstasy.

Features include Radial's award winning 100% discrete class-A guitar buffering for ultimate audio integrity, transformer isolation to eliminate buzz and hum caused by ground loops, 180º polarity reverse to keep effects and balanced signals in phase, and two loops that can let you compare signal paths or combine them to create your magical masterpiece.

The Radial EXTC-SA is without a doubt one of the most innovative effect manipulating devices ever made. And it opens the door to new sounds by taking Reamping technology to an all new level.
