The Bolt 4K LT MAX TX is a real-time wireless video transmitter that supports video signals up to 4Kp30 via HDMI, and 1080p60 via SDI, at a distance of up to 5000+ ft line-of-sight, with less than 1ms of delay. Key features include increased range with faster reconnection times, easier setup with Bluetooth App for iOS or Android, and unlimited receivers using broadcast mode. These devices are cross-compatible with the entire Bolt 4K Family.
Real-Time 4K Wireless Video
Transmit uncompressed video in 1080p and 2160p at 60FPS with less than 1ms of delay. Up to and beyond 5000 feet of range.
True HDR Color
Supports 10-Bit 4:2:2
Improved Wireless Performance
Reliable signal transmission over 13x 40MHz frequencies, with upgraded hardware and less image break-up than previous Bolt generations. Faster reconnection times, automatic signal quality switching, and a more robust frequency hopping algorithm. An additional 5GHz radio frequency link is available for high-traffic locations with excessive interference from other wireless devices.
Bolt 4K features 8x the wireless performance of previous Bolt generations, ensuring video is delivered in even the toughest of RF environments.
Send signal to any Bolt 4K series RX device for expanding workflow requirements.
Supports Broadcast Mode which means you can connect unlimited receivers simultaneously. Broadcast mode also can increase your wireless video range to 5000 feet and beyond with the next-generation Array 4K Panel Antenna.
Input: 1x HDMI 2.0 (up to 4Kp30), 1x 3G-SDI (up to 1080p60)
Output: 1x 3G-SDI (up to 1080p60)
Send start / stop flags, timecode, and other ancillary data over the wireless link. On the receiver side, upload and apply custom 3D LUTs to monitor each take with the look you’re after.

If you would like to return any item(s), please contact us by either emailing firstname.lastname@example.org or calling (+372) 5556 0057. We will share with you a Return Merchandise Authorization (RMA) code and ask that you clearly mark this code outside of your shipping box as you ship your item(s) back for a refund.
You will be liable for the shipping and any applicable customs/duty fees returning the item(s).
If the return is made due to a faulty product, or an incorrectly shipped product, or if you are returning the item(s) due to a defect, or functionality issue, or because it is not the item you have ordered, we will gladly email or mail a return shipping label covering all shipping related expenses. In order to determine whether the return is initiated due to a technical problem, we may ask for you to provide visual support like images or a video on the item(s).
Returned merchandise must be in its original packaging, and placed in a decent shipping box, e.g. the same box that we shipped the items to you in. Please make sure to clearly mark the RMA code you have received from us outside on the box.
Do not forget to cover or peel off any existing shipping labels on the box.

Customs, duties & taxes
There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
