Active stereo DI with phantom power, custom Lundahl transformers, ultralow noise, wide bandwidth, 1 Megohm inputs, XLR outputs, rugged aluminum chassis.
The Grace Design m303s is a premium phantom-powered active stereo DI box engineered for musicians and audio professionals who demand the cleanest signal path on stage or in the studio. With true galvanic isolation and dual custom-wound Lundahl transformers, it ensures ultraquiet, interference-free operation with outstanding low-end clarity and high-frequency detail.
Delivering an exceptionally wide frequency response (20 Hz " 80 kHz), ultralow distortion (0.007% at 50 Hz), and a 124 dB dynamic range, the m303s preserves every nuance of your performance. The Hi-Z 1/4" inputs accommodate both line-level sources and passive instruments, while thru outputs let you feed an amp or secondary destination. Balanced XLR outputs provide professional-grade connectivity, and a switchable -13 dB input pad manages hot signals.
Built in the USA with a durable extruded aluminum chassis and recessed connectors, the m303s is rugged enough for demanding touring environments while maintaining Grace Design's hallmark sonic transparency.
