450ft (150m) LOS Range and 0.06s Ultra-low Latency

The Mars 4K achieves an incredible LOS range of 450ft (150m) and ultra-low latency of 0.06s. Its upgraded dual-core codec chip is capable of a data rate ranging from 8 Mbps to 20 Mbps, with 12 Mbps as the default.

* The LOS range of 450ft (150m) is based on interference-free laboratory measurements.

* The latency of 0.06s is based on test data when 1080p60 signals are transmitted in a laboratory.

HDMI & SDI Dual Interfaces
The Mars 4K supports HDMI and SDI input and output for expanded connectivity and compatibility. The SDI provides expanded frame rate flexibility for both broadcast and production frame rate (decimal-point frame rate) standards and compatibility through production and postproduction.

Flexible Monitoring Options
The Mars 4K transmitter is compatible with up to two receivers or four mobile devices with the app installed. Up to four mobile devices with the app installed allow a maximum of four parties (such as the director, producer, light control personnel, and audio personnel) on the site to monitor the shooting at the same time.

Operational Efficient Design Form Factor
The Mars 4K is featured with superior corrosion and wear resistance for outstanding durability. With disassembly-free, bullet-styled antennas attached, the well-thought-out design form factor optimizes operational functionality for fast configurations.

Smart Channel Scan and Selection
Channel assignment options allow for interference-free transmission. A stable connection is possible automatically upon startup. Smart channel scan helps determine which ones are occupied and selectable.

Color LCD with an Exclusive Rocker-Styled Button
The Mars 4K features a color LCD with a user-friendly UI design that enables quick configurations and status checks. Its uniquely designed rocker-styled button greatly improves the operational setup experience.

Multiple Power Supply Options
The Mars 4K supports a wide range of DC power options–6V to 16V, NP-F batteries, and USB Type-C chargers.
