Sidus Four CRMX Transmitter

The Aputure Sidus Four is a professional four-universe CRMX transmitter and DMX node with a built-in wireless router. It supports multiple lighting control protocols and delivers reliable wireless and wired connectivity for productions of every size. With expandable networking, long-range wireless communication, rugged IP65 protection, and flexible power options, Sidus Four serves as the central hub for modern lighting control systems.

Eight Universes of Control

Sidus Four supports up to four wireless CRMX universes and four wired DMX universes simultaneously, allowing you to transmit up to eight DMX universes at the same time. It works with CRMX, DMX, Art-Net, sACN over EtherCon, and Sidus Bluetooth for flexible lighting network integration.

Expandable Lighting Network

Connect multiple Sidus Four units together through Ethernet to expand your lighting network without practical limits. Grow from four universes to eight, sixteen, or more while maintaining centralized control for productions ranging from small studios to large event venues.

Large TFT Status Display

A bright, color-coded TFT display provides a clear overview of your entire lighting network. The interface makes setup, monitoring, and troubleshooting fast and intuitive while avoiding the panel burn-in issues associated with OLED and LCD display technologies.

Built for Any Environment

The IP65-rated enclosure protects the Sidus Four against dust and water, making it suitable for demanding indoor and outdoor productions. This durable design offers greater environmental protection than transmitters with IP20 ratings.

Flexible Power Backup

Sidus Four operates from AC power and includes a built-in V-mount battery plate for mobile power. An integrated backup battery provides up to 80 minutes of operation, helping keep your lighting network online during unexpected power interruptions.

Reliable Long-Range Wireless Performance

Five dual-band antennas support both CRMX and WiFi communications with a wireless range of up to 800 meters (2,625 feet). Separate operating frequencies of 2.4GHz for CRMX and 5.8GHz for WiFi help reduce interference and improve network reliability.
