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 the 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!

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.
