Grace Design m908

The m908 Monitor Controller is designed for speaker systems up to 24 channels, from stereo to Dolby Atmos™, SONY 360RA™ or any format in between. Built on our legacy of reference audio design, the m908’s audio performance delivers impeccable clarity and detail. Our latest generation AD / DA converters provide incredible dynamic range and resolution, while all new analog circuitry is designed to be effortlessly transparent and musical.

Room Tuning Enhancements

  • Speaker EQ section now includes a familiar frequency/gain style graphical window area which allows quick ‘click and drag’ EQ curve editing. Specific frequency, gain and Q can still be manually entered.
  • High and Low Shelving filters now include slope controls
  • Bass Management LPF’s now include an offset trim amount
  • Channel Delay settings now operate with 1 sample resolution

Network Connectivity

We have added a ‘Link-Local’ network connection, which provides simple direct access to the m908 Web UI from any computer via an ethernet cable.

The All in One Solution

The m908 system consists of a mainframe audio control unit, remote control unit, and a power supply with dual-redundant universal input power modules. The remote control is based on our m905 stereo monitor controller, but scaled up to accommodate added features and playback channel count.

Full Featured

Standard features include a total of 68 digital input channels via AES3, TOSLINK, S/PDIF, ADAT Lightpipe, and USB2. Outputs include 16 balanced analog output channels and 24 digital output channels. Up to 16 channels of analog inputs are available with the addition of the optional 8 channel ADC modules, and an additional option module slot provides up to 32 additional digital I/O channels via Dante™, DigiLink™ and Ravenna / AES67 / st2110.

Powerful DSP

Up to 24 input channels can be received simultaneously and routed to the 24 channel processor, and sample rates of up to 192kHz / 24bit are supported. A powerful DSP section allows for 12 bands of parametric room correction EQ on every channel (or variable numbers of bands per channel totaling up to 85), comprehensive bass management features and individual channel delay.

Plug and Play Simplicity

The m908 is a fully self-contained plug and play monitor controller, with a full complement of monitoring features including cue channels, built-in talkback mic, mono, mute and dim controls, and an exhaustive list of functions relating to surround and immersive playback systems. It is designed to enable professionals and facilities to update their workflows for immersive audio playback with a minimum of effort and cost.

Web UI for Control and Setup

The all-new embedded web control and setup platform allows you to control all monitoring features, and edit, load and store all system parameters. The interface works on any desktop or device browser that is connected to the same LAN as the m908.

Using this platform is as simple as entering the IP address of your m908 into a browser. The m908 will automatically load the control platform and work from there. There is nothing to download or install and it is completely agnostic to the desktop or device OS. This allows complete control and editing of all m908 system parameters from your screen without having to navigate the m908 RCU setup menus. This significantly increases the simplicity and efficiency of operating the m908!

The main monitor control screen provides all the monitoring controls, laid out in a simple, graphical work environment. Any changes made by the web control software are instantly synchronized with the m908 RCU.

The system setup menus on the left provide easy navigation access to every m908 configuration setting, with simple sliders, menus, buttons and text fields for making system setup and calibration changes.

Room correction EQ is as simple as entering values or clicking and dragging EQ points on the screen. Any individual EQ band can be copied and pasted or an entire channel of multiple EQs can be copied and pasted.

Complex solo / mute speaker groupings can be made by simply selecting a specific solo / mute switch and adding or subtracting individual speakers to create the grouping.

System I/O routing in the Web UI can be done in the matrix routing window, which allows you to quickly and easily assign any input channel to any speaker channel. This greatly streamlines any setup process.

The settings panel allows users to enter a browser tab name for the m908, select dark or light theme, activate confirmation dialogs, select list or tile view for the room EQ, and enable a lockout for the home screen controls.

Powerful Room Correction EQ Capability

Firmware v.2 and up provides a significant increase in the amount of total available EQ bands. Since the m908’s original release, one thing has become clear: Dolby ATMOS Room calibration can require very large amounts of room correction EQ. With this release, the m908 can now run 12 bands of EQ per channel on all 24 outputs, at any sample rate (288 bands available).

With the new control and setup software, EQ settings can be copy/pasted between individual speakers or speaker systems. Also, entire room EQ settings can now be imported and exported directly to the m908 imported via .csv files.
