The Reamp HP is designed to accept the signal from the headphone output jack on your interface, making it incredibly easy to connect on the fly without having to repatch cables or dig around behind your studio desk or equipment rack. Simply assign the track you want to Reamp to the right channel of your headphone output and you're ready to feed guitar, bass, or even vocal tracks through your amplifier to record and experiment with new tones and settings. You can even assign stereo tracks to the Reamp HP and sum them down using the dedicated mono switch on the device.
