Next-Level Wireless Video Transmission for Multi-Camera Productions

Seamless Multi-Camera Wireless Workflow

The Hollyland Cosmo C2 2TX & 1RX Kit is designed to revolutionize multi-camera live streaming, electronic field production (EFP), and professional broadcasting. With its dual-transmitter to single-receiver configuration, this system eliminates cabling clutter, synchronization delays, and spatial constraints commonly faced in traditional setups.

By allowing two transmitters to send video signals to a single receiver, the Cosmo C2 ensures flawless synchronization between camera feeds, reducing setup time and increasing efficiency for live event coverage, filmmaking, and commercial productions.

Unrivaled Wireless Transmission Performance

  • Superior Range & Stability: The Cosmo C2 offers a wireless transmission range of up to 1,000 meters (line-of-sight) and a back-to-back transmission distance of over 300 meters.
  • Ultra-Low Latency: With a latency as low as 33 milliseconds, the system outperforms conventional 60ms setups, ensuring precise audio-video synchronization - critical for LED screens and live productions.
  • Advanced HEVO 2.0 Technology: This system automatically detects interference and seamlessly switches to a clean channel, eliminating video stuttering, dropped frames, or signal loss in high-traffic RF environments.

Professional-Grade Video & Audio Capabilities

  • Full HD Transmission: Supports 1080p60, 1080p50, 1080p30, and other frame rates with zero image degradation.
  • Frame Rate Compensation Algorithm: Smooths out low frame rate inputs to 60P, ensuring fluid motion in fast-paced environments.
  • Lossless Audio Transmission: Delivers embedded 2-channel 48kHz 24-bit audio, preserving high-fidelity sound quality for broadcast and post-production workflows.

Versatile Connectivity & Seamless Integration

  • Dual HDMI & SDI Support: The system accommodates both HDMI and SDI connections, making it compatible with a wide range of professional cameras, monitors, and switchers.
  • Comprehensive I/O Ports:
    • Transmitter (TX): HDMI Input, SDI Input, SDI Loopout
    • Receiver (RX): HDMI Output, Dual SDI Outputs
  • Plug-and-Play Streaming:
    • NDI Support for seamless local area network (LAN) streaming without additional converters.
    • UVC Support via USB-C for direct computer streaming—no capture card needed.
    • RTMP Output for instant cloud-based streaming, bypassing external encoders.

Built for Field & Studio Productions

  • Rugged & Lightweight Design: Compact yet durable metal chassis withstands demanding production environments.
  • Flexible Power Options:
    • Transmitters: Support both DC power and NP-F batteries.
    • Receiver: Compatible with DC power and V-Mount batteries.
  • Intelligent Power Management: Ensures long-lasting operation for extended shooting sessions.
