The Teradek Bolt 6 XT Transmitter sends up to 4K60 10-bit 4:2:2 HDR video over 12G-SDI with zero delay, using Teradek's Zero-Delay chip on the 5 GHz and 6 GHz bands. The 750 and 1500 come with no mount, a Gold Mount or a V-Mount battery plate, and the MAX with a Gold Mount or V-Mount plate.

Range and antennas

Line-of-sight range is up to 750 ft or 1,500 ft, and the MAX can be configured for up to 5,000 ft with the optional Array Antenna and Broadcast Mode. Every version has four external 2 dBi V (vertical) antennas, and the 1500 and MAX are also supplied with two H (horizontal) antennas for difficult RF.

Inputs and picture

It takes 12G-SDI or HDMI 2.0, loops out 12G-SDI and converts HDMI to SDI. Formats run from 720p50 to 4Kp60, and delay is under 0.001 seconds. Two channels of embedded audio travel with the picture, and it sends metadata, timecode and start/stop flags from most camera manufacturers.

Receivers and compatibility

One transmitter feeds up to six receivers over an AES-256 encrypted link with RSA-1024 key exchange. In Broadcast Mode a MAX transmitter feeds an unlimited number of paired Bolt 6 MAX receivers; 750 and 1500 receivers don't link to it in that mode. Up to six sets can work in one location, and it's compatible with the Bolt 4K series on the 5 GHz band, including Bolt 4K, Bolt 4K LT and Bolt 4K Monitor Modules.

Power, size and what's in the box

It runs on 6 to 28 V DC through a locking 2-pin connector and is set up through an on-screen menu with joystick navigation. Without a battery plate it measures 132 x 91 x 27 mm and weighs 344 g. Every version comes with a 2-pin to P-Tap cable, a 30 W AC adapter, four V antennas and a USB-A to USB-C cable. Battery-plate versions add front and rear battery cover plates.
