Matrox Monarch HDX - HDMI and SDI Streaming Encoder/Recorder

Matrox Monarch HDX - HDMI and SDI Streaming Encoder/Recorder


The Matrox Monarch HDX allows you to simultaneously stream and record video from SDI and HDMI sources. It is a professional H.264 video streaming encoder/recorder that extends the inputs of the Monarch HD by adding SDI I/O and dual-channel operation, with independent H.264 encoders. It is suitable for streaming and professional workflows that require streaming and recording of content.

Having independent encoders allows each channel to operate separately. You can stream to two different locations, record proxy and master files from the same input or record two inputs simultaneously. One encoder can be used to stream live video while the other encoder records a high quality copy for playback after the live stream. Whether used for live streaming or recording, the Monarch HDX can be integrated into SD or HD productions.

A simple and versatile video encoding appliance specifically designed for broadcasters and webcasters. The Matrox Monarch HDX is for who need a flexible solution that is powerful enough to take on today’s demanding webcasting and recording workflows.

Monarch HDX offers 3G-SDI and HDMI inputs with frame-synchronization to correct any discontinuity at the input, and two independent H.264 encoders that can be assigned to individual tasks. Webcasting to YouTube and Facebook Live is made easy through its simplified set up for these popular platforms.

All that’s needed is to pair the device once with these accounts and it’s automatically retained for subsequent streams. The Monarch HDX can share 30Mb/s of encoding capacity across the two channels. Each channel benefits from a powerful scaling, de-interlacing, and noise reduction engine to ensure only pristine images are sent to be encoded.

The quality of your VOD downloads need never be dictated by the available upload bandwidth. Monarch HDX dual encoders can broadcast a live webstream at one bitrate while simultaneously recording mastering quality H.264 files for immediate availability, such as post event VOD or editing with your NLE of choice.

Compliant with SMPTE 259M/292M/424M (Level A) / 425M

Closed Captioning embedded in VANC of SD or HD SDI signals per SMPTE 334-1 or Captions found in Line 21 of SD signals per EIA-608 are embedded in the essence of H.264 as SEI NAL Units (CEA-608) as per SCTE 128-1 specification.


Video Output




Video Output Resolutions


Preview output of video input signal. Preview output is available when source is SDI or HDMI.

0 frame latency passthrough of SDI Input signal. Output is a clean distribution of SDI incoming signal. Hardware bypass relay present in SDI signal path is "closed" on power failure.

When input is an SD-SDI resolution, the HDMI preview output will show video window boxed on an HD output.


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.

Network mapped drive***

* Support for NTFS (3.1) and FAT32 file system. The Monarch HD 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 HD 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.

** Supports SD and SDHC cards. Only NTFS formatted SDXC cards are supported. (Class 10 highly recommended).

*** 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).


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 appliance 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.


Full Frame Rate


Encode frame rates selection includes;
60/50, 30/25/24 and 15/12.5
