Setup
Live Performance Setup
For live performance, connect the Amp Academy to a mixer or PA system using the XLR DI OUT for a balanced signal. You can also use the 1/4" OUT to connect to a powered FRFR (Full Range, Flat Response) speaker for a personal on-stage monitor. Integrate time-based effects (like modulation or delay) into the INSERT loop using the provided Y-cable.

Recording Setup
Connect the Amp Academy directly to a recording interface via USB-C or XLR DI OUT for instant, high-quality guitar tone without needing an amplifier or microphones. The USB-C connection allows for direct audio streaming to your computer. Ensure IR OUT switches are in the UP position if you wish to use the IR signal for 1/4" out. For DI OUT, hold A/B footswitch and power the pedal to toggle IR signal (A/B indicators flash 3 times for IR ON, no flash for IR OFF).

Silent Practice Setup
For immersive silent practice, connect headphones or monitors directly to the 1/8" PHONE OUT. You can also connect an external audio source to the AUX IN for backing tracks.

Effects Loop Setup
The Amp Academy features a send/return effects loop for integrating external time-based effects. Use the included TRS Y-cable to connect your external pedal(s) to the INSERT jack. The tip of the TRS connector is typically Send, and the ring is Return.
