GRACE DESIGN / m303s

GRACE DESIGN/m303s is an active stereo DI.

■ Stereo Active DI

■ A stereo active DI 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 delivers incredible headroom and dynamic range. Custom-wound Lundahl transformers deliver unprecedented clarity in the low end and detailed high end.

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

Don't be fooled by its elegant appearance; its tough construction is perfectly suited to even the toughest on-site use!
