The AXR4 is targeted at professional sound producers and audio engineers. The AXR4 is a pro-level interface available with Thunderbolt 2 connectivity (AXR4T) or USB 3.0 connectivity (AXR4U). These are generally reserved for high-throughput professional studios and are generally more expensive. The final type of connection is PCIe which involves installing the interface into your computer’s motherboard. Most interfaces connect to a workstation via a USB cable (Windows) or via FireWire (for recording on Apple Mac and iOS devices like iPads). Like inputs, you’ll want to pay attention to what format the outputs are and whether this matches your equipment and needs. The connection format is also important depending on your needs (e.g. Line inputs take line-level (high-power) signals from powered equipment like a synth, whereas instrument inputs are designed for things like mics and guitars that produce a low-voltage signal (this is where preamps help by raising the signal to line-level). Depending on the audio interface, it may have line inputs and instrument inputs.
