Product details

The Bolt 4K LT 3G-SDI TX is a real time wireless video transmitter that supports video signals up to 4Kp30 via HDMI at a line-of-sight distance of up to 1500ft (457m) with no image delay. Key features include increased range, faster reconnection times, easier setup with Bluetooth App for iOS or Android, and more stable connectivity. These devices are cross-compatible with the entire Bolt 4K Family. 

Zero-Delay 4K Wireless Video
Transmit images up to 4Kp30 via HDMI at a line-of-sight distance of up to 1500ft (457m) with no image delay (>0.001sec).

Input: 1x HDMI 2.0 (up to 4Kp30), 1x 3G-SDI (up to 1080p60)
Output: 1x 3G-SDI (up to 1080p60)

True HDR
Supports Rec 2020 HDR in 10-bit 4:2:2 color gamut. Send Log-enabled camera signals with wide dynamic range in order to monitor and achieve balanced highlight and lowlight regions with accurate color reproduction.

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.

Send Signal up to 6 Receivers
Link up to 6 RX receivers to any 1 TX transmitter to enable multiple points of viewing.
