Before connecting, visit the official Audient website to download and install the latest drivers and the EVO Control software for your operating system (Windows/macOS). The EVO Control software provides a customizable mixer and advanced settings for your interface.
2.3 Connecting Microphones and Instruments
The EVO 8 features four combo XLR/TRS inputs on the rear panel for microphones and line-level instruments, and two dedicated JFET instrument inputs on the front. Use the included XLR cable for microphones and the instrument cable for guitars or basses.

This is particularly useful for live streaming, podcasting, or creating content that incorporates computer audio.
