RGBlink mini-mx SDI

The RGBlink mini-mx SDI is a compact, professional 10-channel video switcher designed for live streaming, broadcast, and event production. Featuring quad HDMI 2.0, quad 3G-SDI, NDI|HX2, USB-C UVC, integrated PTZ control, chroma key, dynamic overlays, and simultaneous streaming and recording, it delivers powerful production capabilities in a portable form factor.

The mini-mx SDI is a control desk that fits in one bag, for studios, conferences, lectures and sports coverage. One panel combines a ten-input switcher, an eight-channel audio mix, PTZ camera control, recording and streaming, so a single operator can run the whole broadcast.

Ten connectors, eight audio channels

The mini-mx SDI accepts four HDMI 2.0 sources up to 4K60, four 3G-SDI cameras, a USB camera (UVC) and bidirectional NDI | HX2, from which you build six input channels. A 5.5″ touchscreen, six faders, a T-bar and a joystick share one 291 × 223 × 71 mm panel, powered over USB-C PD (12 V / 3.3 A, max. 40 W).

HDMI and 3G-SDI for professional cameras

Four 3G-SDI inputs (up to 1080p60) bring in broadcast cameras over longer distances, and four HDMI 2.0 inputs accept up to 4096 × 2160p60. Complete the six channels with a USB camera or an RGBlink AI mini via UVC and an NDI source from the local network; the NDI-licensed Ethernet port receives and sends at the same time.

Touchscreen and two HDMI outputs

The 5.5″ touchscreen serves for menu control and as a multiview of all inputs. Two separate HDMI outputs feed monitors with the multiview, the program or a test pattern at up to 1080p60. The USB 3.0 output appears on a computer as a webcam (YUY2/MJPEG), so the program goes straight into OBS, Zoom or vMix.

Mixing eight audio channels

Two XLR/6.35 mm combo inputs for microphones (MIC 1 with 48 V phantom power), a 6.35 mm line input, Bluetooth audio and the audio embedded in the HDMI and SDI inputs – up to eight channels in total. Microphones get noise reduction, equalizer, echo, reverb and voice fusion, and the line input can be delayed by up to 8 frames. Outputs: 6.35 mm and 3.5 mm jack.

Layers, graphics and scoreboard

Build a scene from two video layers, a background image and graphics from the media library – logos, titles or pictures. Dynamic text overlays and a scoreboard show names, scores or time right in the broadcast, and picture-in-picture or split screen are set up without a computer.

One-touch chroma key

Key out a presenter in front of a green or blue background right on the switcher and place them in a virtual studio or in front of graphics. Keying settings are saved in the preset scenes together with the other parameters.

16 scenes and 15 transitions

Up to 16 preset scenes store the layer layout, sources, keying and PTZ camera presets; recall them with the panel buttons or let them rotate automatically. Switch between preview and program with a cut, the T-bar or automatically with one of 15 transition effects. VFA (video follows audio) switches the picture according to the active audio input.

PTZ camera control from the panel

The joystick and zoom toggle control PTZ cameras via VISCA or NDI – pan, tilt, zoom and focus, including movement speed. A camera preset also remembers the input, so recalling it switches straight to that camera. An NDI camera connects with a single Ethernet cable for both picture and control.

Streaming, NDI and recording at once

Over Ethernet the mini-mx SDI streams via RTMP(S) to at least four platforms at once while sending NDI at the same time. With RGBlink TAO Cloud you stream to up to 32 platforms and manage the switcher remotely. Meanwhile the program is recorded as MP4 to a USB drive or SSD of up to 2 TB.

Vertical format for phones

A single switch changes the output from landscape to portrait, so a stream for social networks fills the whole phone screen.

A 5.5″ full-color LCD display provides real-time monitoring of all inputs and outputs, while the tactile control surface with illuminated buttons, knobs, joystick, and T-bar allows fast, confident operation. Integrated PTZ camera control via VISCA and NDI|HX2 supports up to four cameras directly from the switcher, eliminating the need for external controllers.

The mini-mx SDI excels in live streaming workflows with USB-C UVC output for direct connection to conferencing and streaming software, NDI|HX2 and IP streaming, and TAO Cloud integration for cloud-based remote streaming to up to 32 platforms. It also supports simultaneous local recording and streaming, recording up to 100 hours of 1080p video to external USB-C storage.

Advanced production tools include chroma key, two video layers, graphic and logo overlays, dynamic text and scoreboard overlays, VFA (Video Follows Audio), and multiple DVE transition effects. Comprehensive audio support with mic, line, and embedded audio, phantom power, delay control, and live mixing ensures broadcast-quality sound.

Portable, robust, and feature-rich, the RGBlink mini-mx SDI is a complete live production hub that reduces system complexity while delivering professional results.
