Independent shopping perspective
The Korena take
Four to One Mixer brings four signals together at one output, with a dedicated level control and selectable positive/negative phase switch for every channel. That makes it a practical routing hub when balancing multiple instruments or parallel paths into one destination. The compact metal chassis measures 4.75 by 2.5 by 1.5 inches, so it can sit in a pedalboard or studio routing setup without taking much room. It runs on external 9V DC power.
Strong match
Who this is for
- Blending up to four instrument or signal paths into one output with individual level adjustment.
- Parallel routing setups where each incoming channel needs its own selectable phase setting.
Consider the trade-offs
When to look elsewhere
- Rigs needing more than four inputs or more than one output from this unit.
