A small push-button switch, located above the left footswitch, allows the user to change the functionality of this footswitch to perform various Stop, Stutter and Octave Shift effects. A TRS remote jack allows these special features to be triggered by an external switch. Undo / Redo functionality can also be assigned to the left footswitch, allowing the musician to remove previous overdubs and add them back as desired.

In addition to a dedicated knob for loop Volume, the Infinity 2 also features a Decay knob that causes loop audio to fade out progressively during overdub. With the Decay knob set fully clockwise, the layers pile up at full volume. With the Decay knob set fully counter-clockwise, each overdub lasts for only one loop cycle. With the Decay knob set anywhere in-between those extremes, overdubbing on the Infinity 2 creates constantly evolving loop textures that can be instantly snapped back to a previous state using the Undo function.

The Infinity 2’s full-range, high-headroom audio inputs will accept mono or stereo instruments as well as line-level signals. The dual outputs of the Infinity 2 can be routed for stereo output with pass-through and loop audio mixed together, or they can be configured for discrete Wet / Dry operation—where the loop audio is summed to one output, and pass-through audio is sent to the other.
