4-Play

Four DI Outputs in One Box
Switch between four balanced XLR outputs from a single instrument input which is ideal for multi-instrument setups.

One Cable, Multiple Channels
Eliminates the need for multiple DI boxes and cables on stage by routing one input to four different channels in the PA system.

Footswitch Output Selection
Use the footswitch to toggle through enabled outputs; bright LEDs show which channel is active.

Dedicated Mute Switch
Silences all outputs instantly which is perfect for quiet instrument changeovers or tuning between songs.

Assignable Tuner Output
Connects to a tuner pedal and can be set to always-on or active only during mute, keeping your signal clean and convenient.

Ground Lift on Every Output
Each XLR output includes a ground lift switch to eliminate hum and buzz caused by ground loops.

Use Cases for Performers
Perfect for switching between basses, acoustic guitars, mandolins, or even using multiple DI channels for tonal variety with a single instrument.

Compact and Road-Ready
Built with a tough 14-gauge steel chassis, sized to fit on pedalboards, and powered by standard 9V pedal power.
