ACCSOON - CineView Master 4K Lite (TX Only)

This AV transmitter is part of the CineView Master 4K Lite wireless transmission system, offering DCI 4K video quality at 60 fps (using the HDMI input), making it ideal for monitoring, recording, live streaming, and other video production. It uses 2.4 and 5 GHz dual-band transmission technology with DFS to ensure a stable and robust connection with a latency of approximately 35 ms from input to output at 1080p 60 (< 65 ms at 4K 60). Based on the proprietary RTMS 4.0 protocol developed by Accsoon, this technology enables intelligent dynamic adjustment of audio and video data across the two bands, promising greater stability, fast connection times, and the ability to easily handle multiple connections.

Thanks to both dual-band transmission technology and innovative hardware design, CineView Master 4K Lite TX can transmit video up to 350 meters, making it suitable for professional productions on set, in events, and on the move. Not only does it operate over long distances, it does so with great stability. It also supports multiple streaming connections, allowing you to connect up to four wireless devices and one wired device simultaneously via the new USB-C video output at up to 4K 60, which enables wired monitoring on mobile devices with simultaneous power supply.

The CineView Master 4K Lite features clean lines and a modern design, built to withstand heavy production use. It is also optimized for heat dissipation, with the option to reduce fan speed or even turn it off for audio-critical scenarios. Finally, it can be powered via NP-F batteries or a 12 V_DC connector.

In terms of connections, it offers a 3G SDI input, HDMI up to DCI 4K 60 fps, an HDMI loop-out, and a USB-C video output for mobile devices. It also supports cross-conversion: an SDI input can be converted to HDMI on the receiver, while an HDMI input can be converted to SDI output. Accsoon has created a V-Lock adapter so the transmitter itself can be mounted on the back of virtually any camera.

N.B. The battery and power supply are not included.
