Chauvet DJ D-Fi USB 2×4
The D-Fi USB 2x4 is a four-pack of CHAUVET DJ's improved proprietary USB wireless DMX transceiver, designed to streamline any lighting setup by eliminating the need for DMX cables. Each finger-sized unit plugs directly into the USB port of a CHAUVET DJ lighting fixture, drawing power straight from the fixture itself with no external power supply required. New LED indicators simplify channel selection, and the single-material plastic housing is built sleek and purpose-made for reliable signal transmission. Whether managing a small rig or a larger wireless network of fixtures, this easy-to-use D-Fi solution makes setup time a breeze — turning what could be a tangle of cabling into a clean, wireless connection between devices.

Simplified Channel Selection
One of the standout upgrades in this version of the D-Fi USB is the addition of new LED indicators that simplify channel selection. Gone are the dipswitches of older setups — this transceiver makes assigning channels easier and more intuitive, while remaining compatible with D-Fi XLR systems. This means lighting techs and DJs can get their wireless network configured quickly, without fumbling through manual switch settings during setup or between shows.
Wireless Signal Transmission
At its core, the D-Fi USB 2x4 provides instant wireless communication between compatible fixtures. It transfers DMX and ILS signals, as well as master/slave signals, between similar devices — all without a single DMX cable. It plugs directly into USB and ILS-compatible devices, drawing power from that connection alone. This wireless approach reduces clutter and setup complexity, especially valuable in venues or events where cable runs are impractical or time is limited.
Compact, Compliant Design
Practicality extends to the physical design and certifications of the device. Its sleek, single-material plastic housing is finger-sized and lightweight at just 0.7 oz (20 g), with compact dimensions of 3.2 x 0.9 x 0.55 in (81.5 x 25 x 14.2 mm). The unit is fully FCC/RED compliant, and also carries CE, UKCA, and RoHS approvals, making it suitable for use across multiple regions with confidence in its regulatory compliance.
Why We Love This
Our gear experts appreciate the D-Fi USB 2x4 because it removes the hassle of DMX cabling from their setup, letting them focus on the show instead of wiring. Its finger-sized, USB-powered design means no external power supply is needed, and the simplified LED-based channel selection eliminates fiddly dipswitches. For touring acts and DJs who value quick load-ins and reliable wireless signal transmission, this compact, compliant transceiver makes lighting setup faster, cleaner, and far less stressful.
