Hollyland Cosmo C2 2TX & 1RX
€1,149.00
The Hollyland Cosmo C2 2TX & 1RX wireless video transmission system is engineered to meet the rigorous demands of professional multi-camera...
Teradek Bolt 6 LT 750 Int Ant TX/RX Set delivers zero-delay wireless video over 6 GHz + 5 GHz with a clear-line range of 750 ft (≈228 m). Internal omnidirectional antennas keep rigs compact while maintaining strong links in crowded RF spaces. The set pairs one transmitter and one receiver in a rugged, milled-aluminium chassis built for field use, ideal for studio, OB and live production workflows where cabling is impractical.
Carry full-fidelity pictures: 3G-SDI and HDMI I/O support 10-bit 4:2:2 HDR monitoring up to 1080p60 via SDI and 4K30 via HDMI, with <0.001 s end-to-end latency. SDI timecode, start/stop flags and camera metadata pass through. HDMI-to-SDI cross-conversion keeps village and on-camera monitors in sync, while the receiver outputs 4K HDMI and 1080p SDI simultaneously when appropriate.
Link stability is reinforced by DFS-compliant 5 GHz plus UNII-5/6 6 GHz channels, AES-256 encryption with RSA-1024 key exchange, manual/auto channel selection and robust noise rejection that coexists with Wi-Fi. One TX can feed up to six RX units in unicast/multicast modes. Setup and diagnostics run through the Bolt App (Bluetooth) and Bolt Manager, including on-device OSD, spectrum analysis and an integrated test pattern.
Hardware is compact and power-friendly: TX 7.5 oz (212 g), RX 10.7 oz (304 g), 6–28 VDC locking 2-pin input, typical draw 9–11 W. Multiple 1/4-20 and 3/8-16 mounts suit cages or stands; operating temp 0–40 °C. The set inter-operates with Bolt 4K LT/XT ecosystems (link range limited by the shortest device). In-box: TX, RX, SDI/HDMI cables, 2-pin power leads, cold-shoe and light-stand adapters, and a USB cable for firmware updates. Suits cinema cameras, ENG, multicam stages and broadcast, speeding rigging and keeping village monitoring cable-free.
