EarthQuaker Devices Four to One Mixer

The Four to One Mixer is a simple and compact 4 channel mixer with independent level controls and selectable phase for each channel.

This 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 Four to One Mixer 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!

Phase: Use this to select the output phase of the channel. Sometimes other pedals and various instruments will invert the phase of the signal which causes major problems when mixing with other non-inverted signals. If you have a signal that is inverted, flip the phase switch to “–” and the polarity will be corrected. In most cases this switch should stay in the “+” position.

Level: Adjusts the output volume of the channel.

Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs

Current Draw: 50 mA

Input Impedance: 1 MΩ

Output Impedance: 100 Ω

Power: 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!
