Reamp and mix through your guitar pedals

The EXTC-500 is a 500 series module that allows you to get creative with your effects pedals, using them in your mix on any recorded track. Add a touch of distortion or chorus to a lead vocal, flange on a violin, or fuzz on piano – the possibilities are endless. The EXTC-500 takes the line-level balanced output of your recording interface and converts it so an instrument-level high-Z output optimized for guitar effects pedals, so you can Reamp any track through your pedalboard with ease. Once you’ve run the signal through your pedals, connect the output back into the EXTC and it will boost it up to a balanced line-level so you can connect directly to the input of your recording interface. The EXTC features Radial’s class-A buffer for the best audio quality and transformer isolation to eliminate any buzz or hum – so you can focus your attention on using your pedals in new and exciting applications.

The EXTC is a guitar effects interface designed for use inside the Radial Workhorse and other API compatible rack 500 series systems. It features a balanced line level input with variable guitar level send & receive controls for hi-impedance guitar effects. Transformer isolation combined with class-A discreet electronics assures optimal signal transfer. This makes the EXTC the perfect interface for all kinds of effects that otherwise are difficult to use, cause noise or create unbearable hum.
