300 Ft. High Performance DMX Male 3-Pin Bulk Spool Cable

Overview

Featuring the ProX XC-DMX300 300 Ft. High Performance DMX 3-Pin Bulk Spool Cable, a professional-grade raw DMX cable designed for installation professionals, integrators, production companies, and touring operations who need to run custom-length DMX feeds without buying pre-terminated cables that do not fit their rig. Three hundred feet of the same high-performance twisted quad data cable used across the entire ProX DMX line, wound on a spool and ready to cut, route, and terminate exactly where you need it. If your work involves building permanent venue installs, wiring up a touring show from scratch, or stocking a cable shop that produces finished DMX runs to spec, the ProX XC-DMX300 gives you the material to do it right.

A Different Kind of DMX Cable

The ProX XC-DMX300 is not a finished patch cable. It is the raw cable stock that finished cables are made from. There are no connectors on the ends. What you get is 300 feet of precision-spec DMX cable on a spool, ready for field termination with the 3-pin XLR-style DMX connectors of your choice. This is the product for technicians who build their own cables, installers who route cable through conduit and terminate in place, and production companies that need a reliable, consistent cable stock to pull from when building a custom rig.

Construction and Signal Path

The ProX XC-DMX300 is built on a twisted quad data cable design with polyethylene insulation on each conductor. The nominal characteristic impedance is 110 ohms throughout, matched precisely to the EIA-485 / DMX512 standard. At 300 feet of raw stock, the electrical consistency of the cable matters as much as it does in any finished run. Whether you cut 10-foot drops or 100-foot universe runs from this spool, every section carries the same verified specs. Duofoil shielding provides 100% coverage across the full length, and a tinned copper braid adds 85% coverage on top. Both shield layers are continuous through every foot of the spool.

Conductors and Transfer Quality

Conductors are 22 AWG tinned copper. Nominal capacitance from conductor to conductor at 1 kHz is 12.8 pF/ft, with conductor-to-shield capacitance at 23 pF/ft. Nominal propagation velocity is 66%, with a nominal delay of 1.6 nanoseconds per foot. Nominal conductor DC resistance is 24 ohms per 1000 ft at 20 degrees C, and outer shield resistance is 3.4 ohms per 1000 ft under the same conditions. Nominal attenuation is 0.6 dB per 100 ft at 1 MHz. Maximum recommended current is 2.1 amps per conductor at 25 degrees C. These numbers are consistent with every other cable in the ProX DMX family, which means any finished run you terminate from this spool meets the same electrical standard as a ProX pre-terminated cable.

Jacket

The flexible PVC outer jacket is rated for an operating temperature range of -30 degrees C to +75 degrees C. It routes cleanly through conduit, pulls through cable trays, and does not stiffen up in cold outdoor environments. At 300 feet on a spool, the jacket needs to be cooperative during a long pull, and it is.

Who This Cable Is For

Venue installers building permanent lighting infrastructure, production companies putting together a touring show from the ground up, cable shops stocking pro-spec DMX raw cable, and technicians who simply prefer to terminate their own runs to exact length will find the ProX XC-DMX300 is the right starting point. Three hundred feet of consistently spec'd, dual-shielded, DMX512-rated cable stock at a professional level.

Designed by Professionals. Built for Performers. Backed by 40 Years of Excellence.

ProX products are designed by a team of seasoned industry professionals who know firsthand what it means when power fails mid-show. Since 1984, ProX has built its reputation on one principle: every product must perform as hard as the professionals who depend on it. We listen to our customers, and their real-world feedback directly shapes the products we bring to market. The ProX XC-DMX300 is a direct result of that collaboration. When you choose ProX, you are investing in four decades of hands-on expertise and a brand that has never stopped raising the standard for live performance gear.
