The Grace Design M905 is our second generation stereo monitor controller, engineered from the ground up to provide unrivaled audio playback performance with a comprehensive and intuitive feature set.

Included are all requisite professional audio inputs and outputs, both analog and digital, with an asynchronous USB input for jitter free 24/192 computer playback. Outputs include 3 stereo speaker sets, two subwoofer, and our reference headphone amplifier.

The remote is powerful, clean and ergonomic. It includes a headphone output, talkback microphone, and dedicated real time SPL meter. Controls are designed so that anyone unfamiliar with the system can operate it immediately and intuitively, then with a minimal time investment advanced setup and calibration features are accessed and programmed with ease.

The m905 offers more monitoring management features than any current monitor controller. But its true essence is as the most sonically reliable and innate centerpiece available for your studio – homebase for your ears, eyes and hands.

m905 key features
