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.
