Signal loss, hum, and crosstalk in audio runs kill sound quality — especially in live sound rigs and broadcast studios where cable runs are long and EMI is everywhere. Choosing the wrong mic cable means re-recording, feedback loops, and downtime on set.The Belden 2221 is a 2-pair shielded audio/microphone cable built for professional analog and digital audio transmission. It uses 22 AWG stranded copper conductors with an overall foil shield plus individual pair shielding. Low capacitance per foot keeps high-frequency detail intact over extended runs. Made in the USA to Belden’s manufacturing tolerances — this is not a commodity cable.Core Specifications

Why Belden 2221 Stands Up in Demanding Setups
- Dual-layer shielding handles real-world EMI. In live sound environments near dimmer racks, wireless transmitters, or motorized rigging, the foil-plus-braid shield blocks RF interference that single-shield cables let through.
- Stranded copper resists fatigue from constant coiling and uncoiling. Road crews and touring techs wrap and unwrap mic cables daily — solid conductors crack over time. The 22 AWG stranded build survives hundreds of flex cycles without signal degradation.
- Low capacitance preserves tone on long runs. Running 100+ feet from stage snake to FOH console? At 16 pF/ft, the 2221 maintains flat frequency response where standard mic cable starts rolling off treble.
- PVC jacket stays flexible in cold venues. Outdoor festivals, unheated church basements, winter touring — the jacket does not stiffen or crack at low temperatures, unlike cheaper thermoplastic alternatives.
