Earthquaker Devices One to Four Signal Splitter

The EarthQuaker Devices One to Four Signal Splitter is your gateway to expansive, high-fidelity signal routing. With a single input feeding four individually buffered outputs, this compact powerhouse ensures your tone stays strong, clear, and punchy—no matter where it’s going. Each output features a unity gain buffer with a flat frequency response, high 1MOhm input impedance, and ultra-low 100 Ohm output impedance, preserving your tone’s integrity even across long cable runs. Whether you're splitting signals to multiple amps, pedals, or recording chains, the One to Four makes sure your sound arrives exactly how you intended. Four individually buffered outputs for pristine signal splitting Unity gain buffers maintain original tone and clarity High 1MOhm input impedance and low 100 Ohm output impedance Flat frequency response ensures no tonal coloration Ideal for routing to multiple amps, pedals, or recording paths Compact and road-ready design Maintains full signal integrity over long cable runs Current Draw: 15 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.
