■ Stereo Active DI

■ A stereo active DI box with next-generation sound quality.

The m303s is a completely new and innovative ""active/fully isolated"" stereo DI box. It delivers next-generation audio performance for all live stage and studio applications.

GRACE design's unique high-end power supply design provides incredible headroom and dynamic range. Custom-wound Lundahl transformers enable the clearest bass and most delicate treble output ever.

All of this performance is housed in a beautifully robust 1/4-inch extruded aluminum chassis.

Don't be fooled by its elegant appearance; it's built tough enough to withstand even the most demanding field use!
