Four inputs for flexible production

Two HDMI and two 3G-SDI inputs accept multiple formats up to 1080p60. The switcher detects the incoming signal automatically and can scale the output to the selected production format.

Program, Multiview and configurable AUX

Three HDMI outputs are assigned as two program feeds and one Multiview by default. Each can also be configured as an AUX carrying an input, preview, program, clean PGM, colour bars or Multiview.

Streaming over Ethernet and USB

Shark S4 streams directly through the LAN port using RTMP, RTMPS and SRT. The USB-C output operates as a UVC/UAC device for OBS, vMix, Zoom, Teams and other software without a special driver.

Recording to two common media types

The production can be recorded to an SD card or USB drive. The unit supports 2–32Mbps bitrate, CBR/VBR rate control, selectable file segment duration and FAT32, exFAT and NTFS file systems.

Professional keying and composition

Built-in Luma Key, Chroma Key, two PIP layers, POP, downstream key and logo overlay make it possible to build a complete programme without an external graphics system. The media library provides 39 preset patterns and space for 16 imported and 16 captured images.

Audio mixer with delay

The final mix can include embedded audio from two HDMI and two SDI inputs plus two analogue stereo MIC/Line inputs. Audio Follow Video and adjustable 0–500ms delay help keep sound and pictures synchronised.

Fast live-production control

Dedicated PGM and PVW buttons, T-bar, CUT, AUTO, FTB, Mute, Still and two transition-speed presets give the operator immediate control. Production status, audio meters, previews and technical information are available on an external Multiview monitor.
