m303

The Grace Design m303 is a premium active direct box (DI) built for both live stage and studio use, offering exceptional audio clarity and performance. Its standout feature is a custom-wound Lundahl transformer that ensures superb low-end clarity and high-frequency detail, delivering a pristine, natural sound. The m303 is designed with full galvanic isolation, meaning it effectively eliminates any unwanted noise or interference, making it perfect for critical audio applications. Housed in a robust extruded aluminum chassis, this DI box is built to withstand the rigors of professional use, while its sleek design enhances its visual appeal.

Key features include ultra-low distortion and noise, wide dynamic range, and a 1M Ohm input impedance, making it compatible with a wide variety of line or pickup sources. The m303 is powered via phantom power and includes a peak indicator LED to alert users when the signal is approaching clipping. Its efficient design draws minimal power and offers excellent protection against electrostatic discharge (ESD) and radio frequency interference (RFI), ensuring consistent performance in any environment. Trusted for its transparent and musical audio quality, the m303 is a top choice for professionals seeking durability and high-fidelity sound.
