System consisting of transmitter and receiver capable of sending a 4K video signal at 30 fps over a distance of 150 m with a latency of only 60 ms. Mars 4K is designed to offer the best synergy between high performance, compatibility and reliability and extends the already well-known family of Hollyland wireless transmitters and receivers with a product with unique features. The unit obviously also supports FHD and HD formats with variable frame rates: 24p, 30p and 60p. The performance of the new dual-core codec chip, capable of achieving a data transfer rate of 12 Mbps, also contributes to the range of 150 m (LOS) and the ultra-low latency of only 0.06 s. Channel assignments options enable interference-free transmission; intelligent channel scanning helps you to determine which ones are busy and select which ones are free. Mars 4K also allows HDMI and SDI inputs and outputs for extended connectivity and compatibility. SDI offers greater frame rate flexibility for both broadcast and production standards, another of the standout features of the system. The transmitter is compatible with up to two receivers or four mobile devices with the proper App installed. Four mobile devices allow as many people (such as the director, the producer, the lighting manager and the sound engineer) to monitor the footage at the same time. Mars 4K features the proverbial corrosion and wear resistance that Hollyland customers already know, for exceptional durability. Additional features are the "bullet-style" antennas, the color LCD display and its multiple DC power options: 6V to 16V, with NP-F batteries and USB type C charger.
