RGBlink mini-ISO-4S

The RGBlink mini-ISO-4S is a compact, portable 10-channel video switcher in a case, designed for professional multicam production and hybrid streaming. Featuring 4K HDMI and SDI inputs, an HDMI program output, USB recording and UVC webcam output, integrated PTZ control, RTMP streaming, a built-in 14″ monitor and wireless phone charging, it delivers a complete turnkey solution for events, live productions and mobile broadcasting.

The mini-ISO-4S is the mini-ISO switcher built into a rugged case with a 14″ monitor, cooling and connectors routed to the side. Open the lid, plug in the cables and the broadcast can start – whether it is an open-air concert, a garden wedding, a sports match or a corporate event.

A complete control room in a carry case

A rugged case of high-strength PP houses the mini-ISO switcher, a 14″ IPS monitor with 1920 × 1080 resolution and 220 cd/m² brightness in the lid, and a hydraulic rod that holds the lid open. Powerful air cooling is designed for outdoor use; power comes from 100–240 V mains via an IP65 connector. The case measures 360 × 308 × 177 mm.

Wireless phone charging

The mini-ISO-4S has a magnetic wireless charging pad next to the switcher that charges a phone at 15 W, so it stays charged throughout the broadcast. Only phones that support wireless charging can be charged.

Connectors on the side of the case

The switcher inputs and outputs are routed to a panel of rugged aviation connectors – four SDI, four HDMI, network, HDMI program output, recording, webcam output and audio inputs and output. Cables plug into the case without touching the switcher itself.

Touchscreen, T-bar and 15 transitions

The 3.5″ touchscreen shows the menu, signal preview and broadcast status. Preview and program sources are selected with buttons 1–5, and you switch with a cut (CUT), automatically (AUTO) or with the T-bar using one of 15 transition effects. The multiview on the monitor shows all channels with audio, the recording status and the saved scenes.

Chroma key without a computer

Pick the key colour – green or blue – right on the switcher display, without an app, and place a presenter in front of a virtual background or graphics. Luma key and picture-in-picture are also available.

Eight saved scenes

A finished setup – picture-in-picture, keying, selected sources and saved PTZ camera positions – is stored in one of eight scenes (VIEWS 1–8) and recalled later with a single tap. Handy for recurring shows, lectures or changing speakers.

PTZ camera control

The five-way joystick and zoom toggle control up to five networked PTZ cameras via the IP VISCA protocol – pan, tilt, zoom and focus. Camera positions are saved as presets and recalled with a single press.

Streaming, recording and webcam

Over Ethernet the mini-ISO streams via RTMP(S) to up to four platforms at once, and it can also be controlled through RGBlink TAO Cloud from a phone or computer. One button records the program to a USB drive as MP4 (up to 16 Mb/s, FAT32 or exFAT); separate recording of individual inputs (ISO) is not supported. The USB output appears on a computer as a webcam (YUY2/MJPEG).
