- [What’s NEW? 70ms Ultra-Low Latency, 450ft Transmission Range] Compared to the Mars 400S Pro, the Mars 400S Pro II reduces the latency by 30% and extends the LOS range by 50ft, offering an ultra-low 70ms latency and a stable line-of-sight signal transmission of up to 450ft (150m). Whether you require real-time shooting or high-speed transmission, Mars 400S Pro II meets your needs. Farther & Faster!
- [SDI+HDMI Dual Interfaces, 4 APP Monitoring] Equipped with both SDI and HDMI interfaces, Mars 400S Pro II offers wide compatibility for various equipment, whether it’s a DSLR camera or a professional film camera. Whether you choose SDI or HDMI for input, both SDI and HDMI OUT ports support video output at the same time. The TX supports 2 RXs, 1 RX & 2 Apps, or 4 devices monitoring through the Hollyview App.
- [Up to 1080p, 12Mbps Data Rate, 3 Scene Modes] Mars 400S Pro supports input/output video format of up to 1080p via SDI or HDMI interfaces. The system comes with three scene modes (speed, balance, HD), and the data rate is raised from 6Mbps to 12Mbps for HD monitoring quality. At 12Mbps data rate, it enables 1080p high-definition video transmission, delivering clear, refined image quality with rich details.
- [Smart Channel Scan, Direct Live Streaming] Upon startup, Mars 400S Pro II automatically selects the best frequency channels. You can manually select the channels using the RX or the Hollyview App with a visual representation of signal interference levels at each frequency. Mars 400S Pro II supports direct video feed from RX to your PC for live streaming on OBS, vMix, or VLC without a video capture device.
- [Multiple Power Supply and Fan Control Modes] Mars 400S Pro II supports NP-F battery (NOT included), 6~16V DC power, and 5-12V USB Type-C wide voltage power supply options. Equipped with 3 fan speed adjustment modes (Off, Low Speed, Auto), its intelligent cooling design allows it to perform optimally in various usage scenarios, greatly reducing device temperature while ensuring stable signal transmission.
Coming from the 400s to the 400s PRO II has been a seamless, pain-free process. I am a fan of the 400s Pro II! Particularly the exceptional build quality and versatile power options offered. While minimal delay could potentially pose a challenge for live broadcasts or pulling focus, it’s inconsequential for my purposes as a Gaffer. I would highly recommended for its outstanding performance and flexible power choices. The seamless ecosystem integration enhances user experience, delivering top-notch video quality with minimal latency. The system is not only customizable but also offers great value, proving accurate ranges and excellent indoor performance. A perfect addition to your kit if you are already in the hollyland ecosystem, or a great place to dip you toes and start your experience.
Very impressed with Hollyland so far. I also bought the M1 enhanced monitor. We’re using this for the directors and 1st Ac monitor. Build quality is top notch. It’s able to take multiple power sources which is a huge plus. It was cheaper for me to buy this than to rent a teradek system and I am not disappointed. There is about a frame or two of delay which I could see being a problem for someone doing live broadcast but for pulling focus it’s a non issue. Highly recommend.
This is actually my 4th set of Hollyland transmitters (I own a pair of 300s, The Mars M1 Enhanced Monitor, The original 400s and now 400s Pro II).The fact that the whole eco-system works so well with eachother is a huge plus. Depending on the requirements, I have found that each of these has a usecase and the flexiblity is very welcomed.I sold my 400s Pro Is mostly because I thought the quality output vs the 300s wasn’t a big enough difference to keep. Enter the 400s Version II. With previous transmitters I struggled with audio and video syncing for talking head situations such as podcasts. There are plenty of tools in my audio and video mixer to correct this, but the lower latency the more I could trust my hardware in providing a usable audio/video sync in certain situations.I can say that both the video quality and latency work very well! This has made my podcasting and recording environments much easier and convenient to work in. It does what it says on the tin and does it very well so I am very happy with these units. Definitely keeping these unlike the version Is.If I needed 4k for my workflow I might spend the extra money for the 4k transmitters, but haven’t needed them yet.
This works really well, but please specify which batteries are supported. The answers to all of the questions say “standard NPF Sony batteries”.So I bought Sony NPFZ100 BUT despite it having NPF in its model name, it does NOT fit. It is smaller than most other NPF batteries.Unfortunately for me, since I bought the batteries at Best Buy, I can’t it since they don’t accept returns on batteries.Another thing I noticed that if you are not supplying the unit without enough power (i.e. plugging it into a USB power bank that is too weak), you will hear the unit start to make a squeaking sound and it also may just shut off on its own.Other than that, this thing is really solid and is really just plug and play. I tested having the receiver inside the house and then walked outside at the backyard with the doors closed and there weren’t any hiccups at all.
Great tool, recommended.
