The MultiMix 4 USB FX from Alesis is a compact, four-channel desktop mixer with a USB digital audio interface and built-in effects. This portable mixer is packed with features so you can mix an outstanding performance anywhere, making it the ideal addition to any home studio, smaller live performances, portable podcast applications, and even video editing and larger production studio environments. The MultiMix 4 USB FX comes with Alesis DSP effects (such as reverbs, delays, and phasers), while built-in effects processors make it possible to add depth to live sound and enhance recordings alike.
Whether you’re manipulating your sound live or polishing the final product in a recording studio, the MultiMix 4 USB FX is outfitted to give you ultimate control over your audio. It boasts a 2-channel, 5-stage, multicolor LED meter that gives you at-a-glance visual updates of the mixer’s main output level.
- Channels 1 and 2 offer switchable high-pass filtering (at 75Hz), allowing you to manually reduce low-frequency rumbling, handling, and wind noise. Channels 1 and 2 also offer high- and low-shelving EQs, independent gain trims, and independent pan controls, so you can instantly adjust your mix on the fly.
- Channels 3 and 4 are configured as a stereo pair at the level, EQ, and pan controls, letting you easily achieve stereo sound in your live mixes and recordings. Bidirectional stereo playback lets you record the stereo Main output into your computer and listen back, using the mixer to interface software to headphones or monitoring speakers.
Enhance your mix with the MultiMix 4 USB FX’s included bundle of professional software, including the AIR Mini Grand virtual piano, DB-33 virtual organ, and Eleven Lite (which features over 20 premium guitar, amp, and effect models).
Record directly onto your computer using the comprehensive USB recording interface. Simply use the included USB connection to plug the mixer into your Mac or PC to get started—no need to install software drivers. Alternately, you can record stereo audio to your iPad using an Apple iPad Camera Connection Kit (sold separately) for an even more streamlined mixing workflow.
Incorporate this mixer into any setup with its expanded connectivity options. Its 4 line-level input channels allow you to plug in XLR mics (into Channels 1 and 2), while its selectable 48V-phantom power supply makes condenser mics equally easy to connect. Channel 2 lets you directly connect a guitar or bass. Rounding out the I/O is a stereo, ¼” headphone output with independent level control.
