Teradek Bolt 6 XT MAX TX/RX Set Gold-Mount delivers zero-delay (<1 ms) 4K wireless monitoring over 6 GHz + 5 GHz. Both units carry 12G-SDI and HDMI with HDR 10-bit 4:2:2 and AES-256 + RSA-1024 link security. MAX radios reach 5000 ft (1524 m) line-of-sight; an optional Array Antenna concentrates RF for crowded venues. Gold-Mount plates with pass-through keep rigs compact, while 2-pin DC (6–28 V) accepts common on-set power. Pair and manage via the Bolt Manager app (Bluetooth LE), run a spectrum scan, and use the OLED for channel and pairing control. The app also manages LUT output.
The TX ingests up to DCI/UHD 4K60 on 12G-SDI or HDMI; the RX outputs the same over 12G-SDI/HDMI with timecode and metadata carriage. MAX supports Broadcast Mode, raising receiver counts beyond the standard six for multi-monitor distribution. Inter-series compatibility links with Bolt 4K and Bolt 6 (range limited by the shortest unit), easing rental swaps and mixed fleets. An SDI eye-pattern tool checks cable integrity; long-range mode stabilizes picture at the edge of coverage without adding frames.
Hardware is field-ready: replaceable antennas, quiet thermals, and a rugged chassis with locking power. RF channels include U-NII-5 where permitted, reducing interference near Wi-Fi and intercom. Integrated 5-pin USB on the TX enables wireless camera control with SmallHD Smart 7/Ultra (license/cables required), so start/stop and key parameters travel with the link. For carts and studios, the set supports stand or rack mounting with included adapters and cabling.
For live production, ENG, OB and narrative sets, Teradek Bolt 6 XT MAX TX/RX Set Gold-Mount pairs long-range 4K, hardened security, and workflow flexibility with cross-compatibility, Broadcast Mode, and Gold-Mount power—without touching latency.
