4K Zero-Delay Wireless System

Spark 4K is Teradek's latest consumer-level wireless video system capable of transmitting untethered local 4K HDR video up to 500 feet line-of-sight over the unlicensed 5GHz band. It can multicast to up to two Spark 4K receivers simultaneously, features portable power, internal antennas, and a compact design.

What's Included:

• 1x Spark 4K Transmitter/Receiver
• 1x Lightstand Adapter 1/4"-20 (RX)
• 1x Hot Shoe Adapter (TX)
• 1x PSU 30W USB-C Power Adapter (TX)
• 1x PSU 18W AC Adapter 12V DC (Int) – 6ft Cable (RX)
• 1x Ultra Thin HDMI Male Type A (Full) - HDMI

Power and Connect

1. Connect the output from your video source to the HDMI input on the transmitter. Connect the HDMI output from the Spark 4K receiver to the video input on your monitor.
2. Connect power to both the Spark 4K transmitter (USB-C) and receiver (USB-C/DC adapter), then move the power switches on both the transmitter and receiver to the ON ([▶️]) position. Video appears within a few seconds.

? NOTE: Spark 4K transmitters can draw power from the internal battery (if charged), or by using either the included USB-C PD adapter or another USB-C PD source. When the power source is disconnected, and if the transmitter's internal battery has charge, a solid battery icon will display on the front panel. If the battery is depleted, the battery icon will be empty. Spark 4K receivers can use either the included DC adapter, or a USB-C PD source.

Custom/Third Party Power Cables

• Test the power cable polarity with ONLY the power cable connected to Spark 4K. Do not connect video cables.
• Check the power cable for shorts and proper grounding.

Pairing

Spark 4K sets (TX and RX) are paired by default. Devices purchased separately need pairing using Launchpad or the Launchpad App.

Pairing via Launchpad (Desktop)

1. Connect both transmitter and receiver(s) to your computer (Windows/Mac) via USB.
2. Open Launchpad, click the Pairing tab, then tap the Wired Pairing button.
3. Select the devices you want to pair, then click the Pair Devices button. Launchpad will indicate if pairing is successful.

Pairing via the Launchpad App

1. Open the Launchpad App from your iOS or Android device, then tap the Pairing button.
2. Select the transmitter you wish to pair, then tap the Next button.
3. Select the receiver(s) you wish to pair with the transmitter, then tap the Pair! button. The Launchpad App will indicate when the pairing process is completed.

Mounting

Spark 4K devices have a 1/4"-20 threaded hole and two M3 threaded holes on the bottom for mounting the included light stand adapter or other accessories.

• Mount the transmitter onto your camera using the included hot shoe mount adapter, keeping chassis and fan vents clear of obstructions.
• For best results, orient the transmitter for clear line-of-sight to the receiver.

⚠️ CAUTION: DO NOT OVERTIGHTEN SCREWS INSERTED INTO THE 1/4"-20 OR M3 THREADED HOLES. Doing so can damage the transmitter's chassis, voiding the warranty.
