The iRig 2 is the successor to the original and revolutionary iRig adapter, designed to be plug-and-play with nearly all smart devices. It connects to the device's 1/8" (3.5mm) TRRS headphone jack, providing an input for a standard 1/4" guitar cable and an output for headphones, an amplifier, or a P.A. system. A new feature of the iRig 2 is the addition of a gain control dial, allowing users to dial in the perfect signal level for their instrument and mobile device, optimizing sound quality. It also features a dual-mode switch that lets users select between a processed signal (FX) or a clean "thru" signal, offering flexibility for live use. It comes with access to IK Multimedia's AmpliTube software, turning the mobile device into a powerful guitar amp and effects modeling studio.
