The m908 offers extensive connectivity to support even the most complex studio setups, including 24-channel AES3 digital I/O, 16-channel analog outputs, 16-channel ADAT Lightpipe inputs, 24-channel USB input, and stereo AES3, S/PDIF, and TOSlink inputs. Expandability ensures long-term value, with optional Dante or DigiLink modules adding 32 channels of I/O, and an optional 8-channel ADC module providing additional analog inputs.
A monitor controller is the centerpiece of any professional recording or post-production setup, providing the accurate reference required for confident mic placement, EQ decisions, and mix balances. After investing in monitors, processors, microphones, and acoustic design, reliable monitoring accuracy is essential. The Grace Design m908 delivers absolute confidence in what you hear, making it a critical component in achieving professional results.
The m908 Monitor Controller is designed for speaker systems up to 24 channels, supporting everything from stereo to Dolby Atmos™, SONY 360RA™, and all immersive formats in between. Built on Grace Design’s legacy of reference-grade audio, the m908 delivers exceptional clarity and detail. Its latest-generation AD/DA converters offer outstanding dynamic range and resolution, while newly designed analog circuitry remains effortlessly transparent and musical.
The m908 system consists of a mainframe audio control unit, a remote control unit, and a dual-redundant universal power supply. The remote control is based on the acclaimed m905 stereo monitor controller, expanded to accommodate increased channel counts and advanced immersive monitoring features.
Designed to adapt to virtually any professional studio configuration, the m908 provides extensive standard I/O with powerful expansion options for future growth.
Up to 24 input channels can be processed simultaneously with support for sample rates up to 192kHz / 24-bit. The m908’s advanced DSP enables extensive room correction EQ, detailed bass management, and precise per-channel delay control, ensuring accurate monitoring in even the most complex immersive environments.
The m908 is a fully self-contained, plug-and-play monitoring controller featuring cue channels, built-in talkback, mono, mute, and dim controls, and comprehensive immersive playback functions. It allows studios to transition to immersive audio workflows with minimal effort and cost.
The latest firmware significantly expands room tuning, networking, and usability features for faster setup and deeper control.
The embedded Web UI allows full system control and configuration from any browser-connected device on the same network. Simply enter the m908’s IP address to access monitoring controls, routing, EQ editing, calibration tools, and system preferences—no software installation required. All changes are instantly synchronized with the remote control unit for seamless operation.
Firmware v2 and later dramatically increase available EQ processing power, supporting up to 12 bands of EQ per channel across all 24 outputs at any sample rate. EQ settings can be copied, pasted, imported, and exported via CSV files, making complex Dolby Atmos room calibration faster, more flexible, and more precise than ever.
