EarthQuaker
Four to One Mixer
Utility
Four-input passive mixer combining multiple sources into one output. No power, no noise, just signal summing.
EarthQuaker Devices built this utility mixer for combining multiple signal sources. Four inputs sum to one output.
Passive design means no power required. Each input has independent level control. Use it to combine multiple instruments, blend parallel effect chains, or sum stereo to mono.
Simple operation: plug in up to four sources, adjust levels, take the summed output. No frequency response changes or buffering. What goes in comes out, combined.
Basic utility for studios and complex pedalboard setups.
