Radial Engineering EXTC-Stereo Effects Interface and Reamper
The Radial EXTC-Stereo is a stereo effects interface & reamper that bridges pro audio (line-level) gear and guitar/bass pedals, enabling you to insert stereo pedals or reamp tracks with full gain, wet/dry, and phase control. Balanced I/O connections.
Secret Weapon!
The EXTC-Stereo gives you the ability to connect stereo effects pedals such as reverbs and delays to the line-level inputs and outputs of your console or recording interface. Use it to send drum overheads to a multi-tap delay, or breathe new life into a stale keyboard patch with a flanger or chorus pedal. Try it on vocals, strings, or any prerecorded track to add a new creative element to your mixes and revitalize your old pedal collection.
EXTC-Stereo Applications
- Reamping through stereo effects - The EXTC-Stereo acts as the bridge between your recording interface and your stereo guitar pedals, making it easy to use your favorite pedal effects on any prerecorded audio tracks. The EXTC-Stereo converts the dry audio signal from line-level to instrument level for processing through your pedals, and then brings it back up to line-level to record the results.
- Connecting mono guitar pedals - Mono guitar pedals work equally well with the EXTC-Stereo, and you can connect two sets simultaneously to double your creativity. Connect one pedal chain to the left insert jacks on the EXTC-Stereo, and the other to the right.
- Reamping through one or two amplifiers - The EXTC-Stereo can also be used like other Reamp® boxes that feed your tracks through an amplifier. Connect the send jacks to the inputs of your amps and use a microphone to capture the results.
- Recording direct from a pedalboard - With the EXTC-Stereo you can connect your instrument and pedalboard to the line-level inputs on your recording device. Simply connect your pedalboard to the insert receive jacks and adjust the receive level control as needed.
Features:
- Stereo effects loop (send / receive) to integrate pedal chains into a stereo mix
- Front-panel ¼″ inputs (send) and outputs (receive) for pedals
- Send & Receive level controls to optimize gain staging between line and instrument levels
- Wet / Dry blend (mix) control to dial the amount of effect vs original signal
- Effects Loop bypass (A/B mode) switch to bypass the pedal chain for auditioning
- Phase invert switch to correct phase issues with some pedals
- Balanced I/O: combination XLR / TRS inputs, TRS and XLR outputs for interfacing with pro gear
