Hollyland - Mars 300 PRO HDMI Wireless Video Transmitter/Receiver Set (Enhanced)

External Antenna for a compact and sleek look
Featuring an external antenna design, the Hollyland MARS 300 PRO wireless video transmitter set can be stored away neatly. In addition, the installation is made easier by the front mounting holes, and the heat dissipation is optimized by the side heat dissipation holes. The compact devices include many thoughtful designs to let you store, install, and use them without hassles.

One-for-All Thumbwheel Switch
The function menu is operated by a thumbwheel switch. You can choose the desired function or channel by turning the thumbwheel switch. The thumbwheel switch is used to configure all settings, which effectively reduces the number of buttons on each device, making it more elegant and integrated.

All Key Info at A Glance
The high-definition side OLED display clearly shows all necessary info including signal strength, remaining battery power, and channel. Whether the device is installed vertically or horizontally, the screen will face you, and you can see what is displayed without lowering the device.

Quick & Easy Firmware Upgrade via App
Once you have connected to the device using the mobile app, you can start the firmware upgrade by tapping a single button. It's so simple that even a newbie can easily complete the upgrade.

Broader Coverage, Less Latency
The 120m transmission distance supports a larger working range. The 0.1s ultra-low latency ensures instant transmission, allowing the cameraman to collaborate more efficiently with the director, lighting technician, etc. in the shooting or live streaming team.

Unstoppable Power Supply
The Hollyland MARS 300 PRO wireless video transmitter set can be charged via a power bank (via USB Type-C port), DC adapter, or NP-F battery, and you can switch to a different power supply at any time. Multiple power supply options give you more power assurance.

Dual HDMI ports and loop out support
To allow you to connect more devices, both the receiver and transmitter provide two HDMI ports, which support simultaneous input and output. One of the HDMI ports on the transmitters is a loopout, which can output video to a small monitor on the camera, and allow the cameraman to clearly see the shots.

Your Phone Is Your Monitor
You can monitor the shots with an app installed on your phone or tablet. The app provides additional functions including 3D LUTS, focus peaking, zebra, and zooming. By turning phones into monitors, multiple team members can collaborate at zero cost.
