ASK 4 carries HDMI video at up to 4K@30Hz from a transmitter to a receiver without cables. Line-of-sight range is up to 1500 ft (450 m), and 20 frequency channels can be selected. A 1.47-inch display on the unit shows the signal status in real time. A single transmitter can feed up to five receivers, so several people can monitor the same source.
The receiver has an HDMI output and a UVC output of up to 1080p60. UVC lets the signal appear as a webcam-type source in OBS and other streaming or conferencing software, so a separate capture device is often not needed. A 3.5 mm audio output is also provided.
For mobile use, the units run from NP-F970 or NP-F550 series batteries or from a USB-C power input. The system is offered as a 1TX+1RX set or as an additional 2RX pack. Documentation includes a specification sheet, quick start guide, user manual and brochure.
