Matrox Monarch HDX is a compact, easy-to-use, dual-channel H.264 encoding appliance. Designed for complete workflow flexibility, Monarch HDX features 3G-SDI and HDMI inputs with frame synchronization to compensate for unstable sources.

Two independent H.264 encoders provide redundancy or can be set to stream and/or record at individual settings. From any SDI or HDMI input source such as a camera or switcher, Matrox Monarch HDX generates two H.264-encoded video streams at bitrates from 200 Kbps to 30 Mbps. Monarch HDX is packed with features that make it ideal for broadcasters, event producers, medical facilities, CDNs, educational institutions, houses of worship, corporate communicators and legal videographers.

  • SDI Video Output: 0 frame latency passthrough of Input signal. Output is a clean distribution of SDI incoming signal. Hardware bypass relay present in SDI signal path is "closed" on power failure.
  • Audio Input:
    • Processes the first two channels of audio embedded in HDMI or SDI input signals.
    • Unbalanced analog stereo input via 1/8” (3.5mm) jack.
    • Line Level
  • Audio Output:
    • Passthrough of 8 channel of embedded audio channels in HDMI and SDI signals.
    • Unbalanced analog stereo output via 1/8” (3.5mm) jack—passthrough of input.
    • Line Level
  • Note that all outputs are active regardless of audio and video input selection.
  • Extra features:
    • Video Input Format is Auto-Detected in SDI and HDMI.
    • All outputs are active regardless of audio and video input selection.


Frame Synchronization

  • Frame Synchronization: The Monarch HDX contains frame synchronization circuitry designed to compensate for disruptions of the input signal. This circuitry is in place for both SDI and HDMI inputs. Streaming and recording operations will proceed cleanly with repeated or dropped frames.

  • Recording Lengths: Maximum file length of 300 minutes—irrespective of storage type used. File splitting feature allows a user to record continuously for long periods by defining file segment sizes. The Monarch HDX will create these sequential file segments over the course of the recording operation without losing a single frame of video. File segment can have a length of 1 to 300 minutes.


Network Interfaces

  • Connector: RJ45 providing 10/100/1000 Base-T Ethernet with Static or DHCP addressing

Storage Types for File Recording

  • 2 x USB 2.0:
    • Support for NTFS (3.1) and FAT32 file system
    • The Monarch HDX will support writing to USB3 devices at USB2 speeds. Also note, there is a very high variability in the performance capabilities of “thumb” drives (even USB3 versions). Many are optimized for “read” operations while the Monarch HDX requires sustained “write” capabilities. For best results, Matrox recommends using powered USB drives. If small portable media is required, SD cards may be more suitable.
  • 1 x SD card Slot: Supports SD and SDHC cards. Only NTFS formatted SDXC cards are supported. (Class 10 highly recommended).
  • Network Mapped Drive: Support for writing to shared folders in computers found on a network using Windows Share protocols (suitable for Windows system) as well as NFS protocols (suitable for Mac and Linux systems).
