Lighting Accessories

by Alexandra ThompsonAugust 13^th, 2024

Aputure has added the Sidus Four to their lineup of lighting control accessories that connect complex lighting setups within professional environments. Sidus Four supports up to eight DMX universes: four wireless (CRMX) and four wired (DMX). It can connect via CRMX, DMX, Art-Net, and sACN over EtherCon and WiFi. Let’s look at the details.

Aputure has brought us a variety of innovative lighting, such as the Aputure INFINIBAR 4-Light Kits and the Aputure INFINIMAT RGB Light Mats. Aputure also introduced the Sidus One, a wireless DMX networking node with a built-in wireless router capable of connecting DMX, CRMX, sACN, Art-Net, and Bluetooth Mesh in a rechargeable box. The Sidus One could be linked with up to three additional transceivers to create four more universes. Now, with the introduction of the Sidus Four, users can link as many units together as they need via Ethernet.

Key features

• 4 wireless universes, 4 wired universes – control over up to 8 CRMX/DMX lighting universes (and more when linked together)
• Large TFT display
• 80-minute built-in backup battery, plus V-mount battery plate, for reliable power continuity
• IP65 weather rating to withstand the elements

The following video from Aputure provides an extensive walkthrough for the Sidus Four:

Technical aspects

• Four Universe CMRX transmitter
• Built-in 4 port Ethernet node
• Simple/Informative Display
• Built-in Ethernet Switch
• 5.8GHz Wi-Fi Router
• 3/8″ anti-twist screw mount
• Built-in V-mount Battery Plate
• 80-minute Internal Backup Battery
• IP65 Dust and Water Resistance
• Front-facing USB-C port
• Remote management with Sidus Link Pro

A clear, easy-to-read display

The Sidus Four’s 5-inch, color-coded TFT display is quite large and can be read very clearly. It provides users with information and a simple way to gauge the diagnostics (color coding: green is good, red is bad) on the status of their entire lighting network. In addition, the TFT panel avoids the panel burn-in issue sometimes found in OLED and LCD displays. The Sidus Four is designed to work via the Sidus Link app.

Long-range signal reach

Sidus Four features five dual-band antennas that provide coverage for both WiFi and CRMX signals, with a wireless range extending up to 800 meters (2,625 feet). By operating on separate frequencies—2.4GHz for CRMX and 5.8GHz for WiFi—Sidus Four effectively minimizes the potential for network interference due to frequency overlap. This result should provide a much more reliable lighting network.

Power options

Sidus Four features a V-mount battery plate and an 80-minute internal battery for backup power, which should ensure uninterrupted operation in case of power loss. There is also a 3/8″ anti-twist screw mount so the unit can be positioned to where it is easy to read.

Price and availability

The Sidus Four transmitter comes with four male-to-male DMX adapters, five antennas for CRMX and WiFi, a 1-3/8″ baby pin receiver with an anti-twist screw, and a universal power adapter – all in a rugged case. The Aputure Sidus Four is priced at $2,490. For more information, please see their website.
