Hollyland Cosmo C2 2 Transmitters/1 Receiver Kit

Seamless wireless multi-camera 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 the cabling, synchronization delays and spatial limitations typically found in traditional setups.

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

Unrivaled wireless transmission performance

• 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 60 ms installations, ensuring precise audio and video synchronization - crucial for LED displays 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 video and audio features

Full HD transmission: Supports 1080p60, 1080p50, 1080p30 and other frame rates without frame loss.

• Frame Rate Compensation Algorithm: Equalizes low frame rate inputs to 60P, ensuring fluid motion in fast-paced environments.
• Lossless Audio Transmission: Delivers embedded 2-channel 48 kHz 24-bit audio, preserving audio quality for broadcast and post-production workflows.

Flexible connectivity and 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 switches.
