The Alesis MultiMix 8 USB FX is a compact 8-channel mixer offering versatile I/O and built-in digital effects, making it well suited for live sound reinforcement and music/podcast recording. It features four mono channels with 3-band EQ, selectable high-pass filters, and peak LEDs, plus two stereo channels with 2-band EQ. The mono channels can be fed via XLR mic inputs with globally selectable phantom power or via 1/4″ line inputs—the second channel incorporates a switch to accommodate a Hi-Z instrument. Independent aux send knobs allow you to send any channel to your favorite outboard time-based processor or to the built-in effects processor, which provides a variety of reverb, delay, and modulation effects.
Connect a media player to the RCA inputs, and plug the RCA outputs to an external audio recorder. The mixer’s onboard USB audio interface enables direct connectivity with a Mac or Windows computer, should you need to integrate a DAW into your setup. The 1/4″ main, monitor, and headphone outputs have separate level controls enabling convenient routing to multiple monitoring systems. The MultiMix 8 USB FX includes a USB cable and the required power supply.
