Teradek Spark 4K TX
Built on award-winning tech. Built for reliability. Built with your A/V needs in mind.
Spark 4K TX is a wireless transmitter that sends video signals up to 4Kp30 via HDMI, at a distance of up to 500 ft line-of-sight, with less than 1ms of delay.* Transport your 4K HDR video from source to screen with no perceivable delay.
Unleash high-quality, zero-delay wireless A/V transmission for conferences, live events, worship services, sports, and more.
Key features include dual-powering options for backup battery redundancy, lightweight design, signal status and pairing with the Launchpad desktop and mobile app, and multicast transmission.
Zero-Delay Signal Integrity
Transmit video with less than 1ms of delay.
Mobility
Get wireless coverage for up to 500 feet of range. Now, your computers, cameras, switchers, and gimbals are all within range with robust wireless connectivity.
4K HDR Color
Maintain premium video quality at 10-Bit 4:2:2 color sampling.
Smart Transmission
Transmit in crowded areas with confidence. Spark 4K uses the 5GHz frequency for less sensitivity to line-of-sight obstructions, and smart frequency hopping to automatically find a clear channel.
Lighter than lightweight
Spark TX weighs just 5.6oz, perfect for on-the-move camera work.
Video Processing
Visually Lossless
Audio Processing
48kHz 24-bit PCM
TX Internal Battery Life
Up to 2 hours.
Transmitter tested at 125 mins when transmitting at 1080i59, 104 mins when transmitting at 4Kp30.
