Overview
Blackmagic Design builds this converter for patching one HDMI device into another run of equipment. A single HDMI port carries the signal in or out, and the box is sized to sit on a desk or rack shelf while it works. The housing is black and the unit weighs several pounds, which holds it planted once placed.
Buyers reach for a compact converter when a source and a display or switcher will not talk over the same cable type. One HDMI port means the box handles a single link at a time, so a setup with several sources needs several units or a switcher. The listing leaves the signal formats and the conversion direction unstated, and those are the two facts that decide whether it works in a given chain.
Who it's for
A desk or rack setup with one HDMI device that has to feed another piece of equipment is where this unit belongs. Buyers who need to convert several signals in parallel, or who need the direction and format spelled out on the box, should look elsewhere.
Pros and cons
- Single HDMI port simplifies the wiring
- Blackmagic Design converter housing
- Compact footprint for a desk or shelf
- Black finish blends into a rack
- Input and output signals not listed
- Conversion direction not stated
- Maximum resolution not listed
- No cables or accessories listed
Performance notes
The conversion happens inside the housing, so the result depends on the format the incoming HDMI signal uses and what the receiving device accepts. Because the port count is one, the box can only serve a single link at a time, and any chain that needs simultaneous feeds will not work through it alone.

Frequently asked questions
How do I keep the Blackmagic Design CONVCMIC/SH converter working over time?
Keep the single HDMI port free of dust and seat the cable fully, since the listing shows one port and no spare connection. Set the unit on a flat surface that carries its weight rather than hanging it by the cable, and check the connector for strain if the signal drops.
What is included with the Blackmagic Design CONVCMIC/SH converter?
The listing covers the converter itself, with a black housing, one HDMI port and a stated weight and footprint. No cables, power supply or mounting parts appear in the bullet points or specs, so plan to supply those separately.
Which devices can I connect to the Blackmagic Design CONVCMIC/SH?
Any device with an HDMI connection can be cabled to the single port. The listing does not name the signal formats, the resolution or the conversion direction, so check those against your source and display before buying.
