EarthQuaker Four to One Mixer 4-Channel Audio Combiner with Independent Volume and Phase Switches

The Four to One mixer is a simple and compact 4 channel mixer with independent level controls and selectable phase for each channel. This was primarily designed to be used with our One to Four Splitter to create 4 parallel signal paths, but it can be used just about anywhere you need to mix four different sources into a single output with your unique sound! 

High Headroom Device with Broad Compatibility

This high headroom device features a high 1 Mohm input impedance and a low 100 ohm output impedance ensuring all signals maintain their sonic integrity throughout their journey, even on long cable runs. The high headroom input impedance of this device allows it to accept a variety of instruments without distortion or clipping. This was built to handle just about anything, including guitars, basses, synthesizers, drum machines, and more!

Phase Selector Switches for Each Channel

Phase selector switches for each channel will make sure to correct any issues you might have from mixing multiple different signals with opposing polarities. Sometimes mixes can sound out-of-phase, leaving the resulting signal sounding thin or tinnier. Adjusting the Phase on the Four to One Mixer will help you avoid these issues. When used in conjunction with the Four to One Splitter and our Flexi Loops, you can create wild parallel signal paths at the flip of a switch! Use it to mix 4 instruments into one amp! Run four synths into a single channel! Put the whole band through your wall of amps! The possibilities are still nearly endless.
