Liberty AV Solutions 22-1P-EZ-BLK 22 AWG 1-Pair Shielded Broadcast Audio Cable — 1000 ft Reel

The Liberty AV Solutions 22-1P-EZ-BLK is a high-performance 22 AWG, 1-pair shielded broadcast audio cable engineered for general-purpose line-level balanced audio, low-voltage control wiring, and RS-232C signaling in professional AV and broadcast installations. Rated NEC CMR and CEC CMG FT4, it supports balanced audio runs up to 450 feet (assuming 600 Ω source impedance) and ships on a 1,000-foot reel ready for large-scale deployment.

For AV integrators sourcing the best 22 AWG shielded cable for broadcast audio or bulk shielded audio cable for studio installation, the 22-1P-EZ-BLK delivers a decisive workflow advantage: the foil shield is bonded directly to the jacket, enabling clean, consistent EZ-Strip terminations without the frustration of stray shield material. This design eliminates a common source of installation errors and accelerates cable prep on high-count installs — a critical benefit for integrators working against tight project schedules.

The 22-1P-EZ-BLK is manufactured to UL444 standards and complies with NEC Articles 725 and 800, making it a code-compliant choice for in-wall and plenum-adjacent runs where CMR-rated cable is required. Its 100% aluminum/polyester foil shield paired with a 22 AWG tinned copper drain wire delivers reliable interference rejection across the full reel, while the RoHS-compliant construction satisfies environmental compliance requirements for commercial and institutional projects.

Key Features of the Liberty AV 22-1P-EZ-BLK Shielded Audio Cable

• EZ-Strip Shield Design: The foil shield is bonded directly to the PVC jacket, enabling fast, clean terminations and reducing installation time on high-density cable runs.
• 22 AWG 7-Strand Tinned Annealed Copper Conductors: Delivers consistent conductivity and long-term corrosion resistance — essential for permanent in-wall and rack room installations.
• 100% Aluminum/Polyester Foil Shield + Tinned Copper Drain: Provides complete coverage against electromagnetic interference, preserving signal integrity across full 450-foot balanced audio runs.
• NEC CMR / CEC CMG FT4 Rated: Meets NEC Articles 725 and 800 for in-wall riser installations, satisfying code requirements without requiring conduit on most commercial projects.
• RoHS Compliant: Meets EU RoHS Directive 2002/95/EC environmental requirements for use in commercial, institutional, and government installations worldwide.
• Tightly Twisted Pair Construction: Six twists per foot with a 2.0-inch pair lay length minimize crosstalk and optimize noise rejection for clean, hum-free line-level audio.
• 1,000-Foot Reel Format: Ships on a full 1,000-foot reel, enabling efficient bulk pulls on large-scale AV integration projects without mid-run splices.
