Fully Isolated Active DI
The New DI in Town
The new Grace Design m303 and m303s (stereo) are active, galvanically isolated DI boxes, delivering next-generation audio performance for all stage and studio applications. Our advanced power supply design provides incredible headroom and dynamic range, while the custom-wound Lundahl transformer outputs amazing low-end clarity and high frequency detail. All of this performance is packaged in beautiful and rugged ¼” extruded aluminum chassis. Don’t let the elegant exterior fool you, these things are built.
