Looking for a simple A/V solution for zero-delay wireless transmission that’ll wow your audience?


Introducing Spark 4K TX. Spark 4K TX is a wireless transmitter that transports your 4K HDR video from source to screen via HDMI in 0.001 seconds.¹ With zero-delay IMAG projection, you can finally give your entire audience a first-row seat of the speaker on stage without the distracting delay.

Spark 4K boasts a wireless coverage of up to 500 feet of range – so your equipment and display screens are all within range with robust wireless connectivity.
