Setup
Powering the Device
The A1X FOUR can be powered by four AA batteries or an optional AC adapter (Zoom AD-16). For optimal performance and extended use, an AC adapter is recommended. When using batteries, ensure they are correctly inserted according to the polarity markings in the battery compartment.
Connecting Your Instrument and Amplifier
- Connect your acoustic instrument to the A1X FOUR's input jack using a standard 1/4-inch instrument cable.
- Connect the A1X FOUR's output jack to your amplifier, PA system, or audio interface using another 1/4-inch instrument cable.
- If using a microphone, connect it to the MAA-1 mic adapter (if included with your model) and then connect the MAA-1 to the A1X FOUR's input.

Operating the A1X FOUR
Navigating Patches and Effects
The A1X FOUR features numerous preset patches and allows for user-created patches. Use the footswitches to scroll through patches or engage/disengage individual effects within a patch. The control knobs below the display allow for parameter adjustments of the selected effect.
