BELDEN 9451P, 22 AWG 1-PAIR SHIELDED PLENUM AUDIO CABLE
BELDEN 9451P is a plenum-rated (CMP) version of the industry-standard 9451 balanced audio cable. It features a single pair of 22 AWG stranded conductors with high-quality shielding, specifically designed for professional audio, intercom, and line-level control systems in building areas requiring advanced fire safety compliance.
Product Description
Built to provide the same trusted electrical performance as the classic 9451 while meeting strict building codes for air-handling spaces:
Reliable Conductors: It utilizes one pair of 22 AWG stranded (7x30) tinned copper conductors. This gauge is the professional standard for balanced audio, offering a perfect balance of conductivity, flexibility, and termination ease for XLR and TRS connectors.
Plenum Compliance (CMP): Encased in a Plenum-rated (CMP) Flamarrest® jacket, the cable is engineered for maximum flame resistance and minimal smoke generation. This allows for safe, code-compliant installation in ceiling plenums and raised floors without requiring metal conduit.
Superior Interference Shielding: The cable is protected by a Beldfoil® shield (100% coverage aluminum/polyester tape) and a 22 AWG stranded tinned copper drain wire. This ensures excellent common-mode rejection and total immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) in high-density rack environments.
Ease of Installation: Despite its plenum rating, the cable remains flexible and easy to pull through conduits or tray systems. The pair is twisted to maintain signal balance, helping to keep audio runs hum-free and transparent over long distances.
