BELDEN 1801B, 24 AWG 1-PAIR SHIELDED PLENUM AUDIO CABLE
BELDEN 1801B is a high-performance, plenum-rated (CMP) balanced audio cable. Featuring a single pair of 24 AWG conductors and professional-grade shielding, it is engineered for critical audio distribution in commercial building plenums, air-handling spaces, and environments where strict fire-safety compliance is required.
Product Description
This cable is designed to deliver pristine audio signals while meeting the most rigorous safety standards:
Precision Conductors: It consists of one pair of 24 AWG stranded (7x32) tinned copper conductors. This ensures the flexibility needed for installation while providing the reliable conductivity required for balanced analog audio lines.
Plenum Fire Safety (CMP): The cable is encased in a Plenum-rated (CMP) Flamarrest® jacket. This advanced material is specifically formulated to be highly flame-retardant and low-smoke-producing, making it fully compliant for installation in drop ceilings and raised floors without the need for additional metal conduit.
Superior Shielding: It features a Beldfoil® shield (aluminum/polyester tape, 100% coverage), which provides complete protection against electromagnetic interference (EMI) and radio frequency interference (RFI). A stranded tinned copper drain wire is included to ensure a consistent, low-impedance ground path.
Audio Integrity: The conductors are insulated with Flamarrest®, which offers excellent dielectric properties. This, combined with the cable's tight-twist geometry, ensures minimal signal degradation and high common-mode rejection—essential for clean, hum-free audio in professional installs.
