The Hollyland Mars 300 Pro Single TX is a standalone wireless video transmitter designed for lightweight mirrorless and DSLR camera rigs.
It is tailored for solo shooters, indie filmmakers, and live-streaming creators who need to beam a high-definition video feed wirelessly without losing their on-camera monitoring layout.
Dual HDMI Interface & Built-In Loopout
The standout physical feature of the Mars 300 Pro TX is its side-mounted dual-port array. It does not actually ingest two separate camera feeds simultaneously; instead, it serves as a signal splitter:
-
HDMI Input: Receives the live uncompressed feed from your camera body.
-
HDMI Loopout: Passes that exact input signal right back out via wire. This lets you connect a local on-camera monitor or electronic viewfinder (EVF) directly to the transmitter, eliminating the need for separate HDMI splitters or specialized cages.
Core Hardware & Signal Strengths
-
300ft Wireless Footprint: Transmits rock-solid video and audio data up to a 300-foot (90-meter) Line-of-Sight (LOS) operational radius.
-
Low Transmission Latency: Achieves a highly responsive latency of roughly 0.1 seconds (100ms). While not ideal for fast-paced focus pulling on cinema lenses, it is perfectly suited for framing, remote directing, client monitoring, and vlogging.
-
Flexible Monitoring Ecosystem: You can monitor the transmission through a physical Mars 300 Pro Receiver or bypass a dedicated hardware box entirely. Using the HollyView App (iOS/Android), the Single TX can broadcast to up to 3 mobile devices (tablets or smartphones) simultaneously.
-
Integrated Screen & Thumbwheel Menu: Features a crisp, side-mounted OLED telemetry display that shows battery levels, frequency channels, and video formats. A multi-functional clickable thumbwheel makes navigating settings quick and easy.
