Decimator Design MC-DMON-9S 9-Channel openGear 3G/HD/SD Multiviewer

Multi-View SDI Signal Monitoring in an openGear Format
The Decimator Design MC-DMON-9S is a 9-channel SDI multi-viewer built into an openGear-compatible form factor, making it a compact and rack-ready solution for signal monitoring in studio, OB, and A/V control environments. This unit allows you to view up to nine separate SDI sources on a single monitor, with each input auto-detecting SD, HD, or 3G-SDI formats. Designed to fit seamlessly into openGear frames, it provides the functionality of a full-featured multi-view processor without the bulk of standalone gear.

Flexible SDI Input Support With Automatic Signal Detection
Each of the nine inputs supports both 3G-SDI level A and B standards, giving it full compatibility across broadcast workflows. Inputs auto-detect signal format and frame rate, allowing for a mix of sources running simultaneously. Whether you’re monitoring camera feeds, recorders, or router outputs, the MC-DMON-9S ensures correct scaling and layout presentation without the need for manual adjustments.

Configurable Layouts With Recallable Presets for Fast Workflows
The unit supports both standard and custom layout modes, giving you control over how sources appear on screen. Custom layouts can be saved and recalled via USB, and multiple built-in viewing presets are also available for fast changes between configurations. This makes the MC-DMON-9S ideal for production workflows that shift between different monitoring needs across events or studio setups.

Per-Window Overlays for UMD, Audio, Format, and Guides
Every channel window can be individually configured with on-screen overlays, including 16-character UMD labels, 16-channel audio meters, signal format status, safe action/title zones, center markers, and audio ID. These visual tools provide fast diagnostic feedback and help operators keep track of key signals in complex routing scenarios. Overlays can be toggled per window, allowing only the information you need.

Fast Input Switching With Selectable Output Formatting
Inputs can be switched quickly to full-screen display mode with input scaling applied. This enables close monitoring of a single source while still using the multi-view processor for all nine feeds. Both multi-view and full-screen modes support selectable output resolutions to match your display or downstream system, providing optimal clarity and performance.

Low-Latency Architecture for Asynchronous Signal Support
Each SDI input includes its own buffer, enabling smooth operation even when input signals are not locked or synchronous. This ensures stable display performance and makes the unit suitable for live broadcast setups where timing across multiple sources may vary. A pass-through mode also allows any input to be routed directly to the SDI output if needed.

openGear Integration With Software Control and USB Interface
As an openGear module, the MC-DMON-9S fits into any standard 2RU openGear chassis and is controllable via DashBoard software for unified signal management. A USB port provides local control and firmware updates, giving you both remote and direct setup options. Its flexibility and integration with existing openGear frames make it an ideal upgrade for professional monitoring systems.
