Polycom 2457-29051-001 50 ft HDX Microphone Array Cable

The Polycom 2457‑29051‑001 is a professional-grade 50 ft (15.24 m) CLink 2 cable, designed to connect Polycom/HP HDX or Group Series microphone arrays (e.g. HDX tabletop array or SoundStation IP 7000) to the codec or SoundStructure input. Featuring Walta‑style audio connectors (Walta male to Walta female) on both ends, it supports full proprietary signaling used in HDX platforms. The cable is shielded copper, built to maintain audio integrity in conferencing environments. Its generous length is ideal for flexible microphone placement in medium to large rooms. While Poly no longer manufactures this exact part, it remains the standard OEM cable for first-array connections. Packaged estimations include a small retail box containing the coiled cable. At ~2 lbs shipping weight and roughly 10 × 6 × 6 inches packaging, it balances robust build with manageable portability. It’s an essential replacement or extra for AV integrators deploying legacy Polycom codecs with extended mic layouts.
