Grace Design m308: 8-channel active DI box for professional studio and live use

The Grace Design m308 is an 8-channel active direct box designed to deliver the highest level of audio performance in studio, live and professional installations. With full galvanic isolation and an advanced power supply design, it ensures a clean, stable and interference-free signal even in the most demanding settings.

Lundahl transformers and uncompromising sound quality

The sonic heart of the m308 is the custom-wound Lundahl transformers, which ensure extremely detailed output across the entire frequency spectrum.

Defined bass and crystal-clear high frequencies

Frequency response is wide and precise, with solid, controlled low frequencies and extremely transparent highs, ideal for electronic instruments, guitars, synths and line-level signals.

High performance through superior headroom and dynamics

The advanced 48V phantom power supply system offers exceptional headroom and wide dynamic range, allowing even very loud signals to be handled without distortion.

Total signal control

Each channel is equipped with -13dB pads to attenuate signals that are too loud, peak LED that activates at -3dB from clipping, and Iso/Gnd switches to resolve any ground problems.

Maximum versatility for studio, stage and installations

With its 8 channels and 19" rack mount format, the m308 is perfect for multichannel applications, whether in the studio, live settings or fixed installations.

Universal compatibility

The 1 MΩ input impedance allows you to connect any source, from passive pickups to line-level signals, while maintaining maximum sonic integrity at all times.

Rugged construction and professional reliability

Built in a solid 1U extruded aluminum chassis, the m308 is designed to withstand heavy use. The design also allows rack ears to be mounted on either side for added flexibility.

Made-in-the-USA build quality

Made in the USA and backed by a 5-year warranty, it is a reliable and durable solution for audio professionals.
