Grace Design m905 Stereo Reference Monitor Controller (Silver)

All main audio and power supply circuitry is housed in a 2U rack mount mainframe, while system control is managed by a sleek, ergonomic remote control unit. This new RCU is a combination of dedicated hardware and a color graphical LCD display. All primary monitoring features are accessed via hardware switches and a rotary encoder, while all system information is presented by the graphic LCD and illuminated switches. This hybrid design allows for the solid feel and function of traditional hardware with the added power and functionality of a graphical user interface.

With stunning sonic performance and timeless design, the m905 is a mark of genuine progress in the pursuit of high quality audio production. Intuitive, reliable and beautiful, it is the perfect studio centerpiece – home base for your ears, eyes and hands.
