Hollyland COSMO C1

Introduction

The Hollyland COSMO C1 is a wireless video transmission system designed for professional video production. This guide provides essential information for setup, operation, and support.

Typical Setup

The typical setup involves connecting a video source (camera) to the transmitter via HDMI/SDI IN, and connecting the receiver to a monitor via HDMI/SDI OUT. The system uses antennas for wireless transmission.

Diagram Description: A visual representation shows a camera connected to a transmitter unit, which then wirelessly transmits to a receiver unit connected to a monitor. Arrows indicate signal flow (HDMI/SDI IN to transmitter, HDMI/SDI OUT from receiver).

Note: For improved transmission stability, especially when there's a significant height difference between the transmitter and receiver, it is recommended to use Hollyland mushroom antennas on the transmitter. ?
