Earthquaker Devices Four to One Mixer

The EarthQuaker Devices Four to One Mixer is a compact and powerful 4-channel utility that lets you blend four separate signals into a single output with ease. Each channel features its own level control and selectable phase switch, giving you total control over your mix. With a high 1 MOhm input impedance and a low 100 Ohm output impedance, it preserves your tone with crystal clarity—even across long cable runs.

Originally designed to pair with the One to Four Splitter for parallel routing, this versatile mixer fits perfectly in any setup where multiple sources need to come together. Whether you're combining instruments, effects, or parallel signals, the Four to One Mixer ensures your sound stays clean, cohesive, and perfectly in phase.

• Four independent input channels with individual level controls and phase switches
• High 1 MOhm input impedance and low 100 Ohm output impedance
• Compact design ideal for pedalboards and studio setups
• Selectable phase (+/-) on each channel to correct polarity issues
• Preserves tonal clarity across long cable runs
• Designed to pair perfectly with the EarthQuaker One to Four Splitter
• Passive mixing circuit with active impedance buffering for signal integrity
• Current Draw: 50 mA
• Input Impedance: 1 MΩ
• Output Impedance: 100 Ω

Please note: This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES.
