Teradek Bolt 6 XT 750 TX/RX Deluxe Set V-Mount is a zero-delay wireless video link operating in 6 GHz and 5 GHz to reduce congestion on set. The 750 model carries 4K signals up to 750 ft (228.6m) line-of-sight, cross-compatible with Bolt 6 in 6 GHz and Bolt 4K over 5 GHz. Latency stays under 1 ms, maintaining precise camera-to-monitor timing for focus, HDR look evaluation & live switching. The Deluxe Set adds V-Mount power accessories and a hard case for field deployment.
I/O covers 12G-SDI (in + loop on TX, out on RX) and HDMI 2.0 (in on TX, out on RX) with uncompressed transport and 10-bit 4:2:2 up to DCI/UHD 4K60. Ancillary features include timecode and start/stop pass-through, HDR (Rec. 2020) pipeline compatibility, and an SDI Eye Pattern Tool to verify cable integrity. Embedded audio carries 2-channel 24-bit/48 kHz LPCM for confidence monitoring.
RF performance uses efficient 20/40 MHz channel bandwidths plus app-based spectrum analyzer and channel selection via Bluetooth. Link security relies on AES-256 encryption with RSA-1024 pairing. One transmitter can feed up to six receivers, keeping director, 1st AC, DIT and video village in sync. The 750 kit ships with V-antennas and robust RP-SMA connectors for serviceability.
Power and rigging suit broadcast carts and handheld rigs alike. The RX integrates a V-Mount plate for on-monitor builds; both units accept 2-pin LEMO DC from D-Tap sources. Typical draw: 20 W (TX) and 18 W (RX). Compact housings (TX 132×91×27 mm / 344 g; RX 138×112×27 mm / 430 g) fit cages or monitors using 1/4-20 and 3/8-16 points.
