  • 93% Braided OFC Shield Rejects RF Interference And Hum On Extended Runs
  • Balanced Signal Design Maintains Clean Audio Even Through Conduit Near Power Lines
  • Flexible Yet Durable Jacket Handles Repeated Terminations And Daily Production Use
  • ProX Limited Lifetime Warranty Covers Every Spool For Long-Term Investment Protection

The ProX XC-MIC300 is a 300-foot bulk spool of balanced microphone cable intended for audio professionals who need to terminate their own lengths for permanent installs, touring systems, broadcast infrastructure, or production truck builds. Rather than working around fixed cable lengths, engineers and integrators can cut exactly what each run demands, eliminating waste and avoiding the signal compromises that come with daisy-chained or undersized cables.

The cable is constructed around 20 AWG oxygen-free copper conductors paired with a 93% braided OFC shield. At extended run lengths, shield coverage becomes critical. The 93% braid is engineered specifically to reject RF interference, hum, and noise pickup that becomes increasingly problematic when cables run alongside power lines, under stage floors, or through conduit in permanent installations. The balanced signal path carries that noise rejection through every foot of the run, which is why this cable is suited for applications where signal integrity at distance is non-negotiable.

The jacket construction balances flexibility with durability, holding up through repeated terminations, recoiling, and the day-to-day handling of active production environments. Whether stocking cable for a rental house, wiring a fixed installation, or preparing a custom snake build, the XC-MIC300 gives technicians full control over the finished product. Every spool is backed by the ProX Limited Lifetime Warranty.
