The MIX2:1 is a simple yet highly useful mixer that passively sums two audio channels down to one. This enables you to easily sum the stereo outputs of a console, recording interface, or portable playback device down to mono. You can also combine two separate signals, matching the input levels between them. Inputs can be accessed via XLR or ¼” connectors, allowing you to use balanced or unbalanced sources. The MIX2:1 maintains the integrity of your audio quality, with minimal insertion loss, no phase shift, and completely passive summing.
