Signal interference and cable failure in live sound and broadcast setups cost time, money, and reputation. cheap audio cables pick up hum, crackle under movement, and degrade fast in demanding environments. Belden 8723 solves this — it is a purpose-built 2-pair 22AWG shielded signal cable designed for microphone and line-level audio where reliability matters.What Is Belden 8723?Belden 8723 is a 2-pair (2PR) 22AWG stranded shielded cable built for balanced audio signal transmission. Each pair is individually shielded with an overall braid, minimizing crosstalk and EMI pickup. The flexible PVC jacket handles frequent coiling, dragging across stages, and routing through tight conduit — typical in touring, installation, and permanent build-outs.Core Specifications

Why Engineers Choose Belden 8723
- Low noise floor in high-EMI environments. The dual-layer shield (pair + overall) keeps RF interference and hum out of mic-level signals — critical on stages near dimmers, wireless transmitters, and power cables.
- Flexible enough for touring, tough enough for install. The 22AWG stranded construction and PVC jacket survive repeated bending, cable drops, and floor rolls without conductor fatigue or shield breakage.
- Consistent impedance and capacitance across runs. Matched pair construction ensures balanced audio performance over long cable runs (100ft+), reducing phase issues in multi-mic setups and snake cables.
- Belden quality control, not generic specs. Every spool is tested for continuity, shielding effectiveness, and jacket integrity — no surprises when you pull it on a live show or in a studio session.
Typical Applications & Industries
- Live sound reinforcement and stage touring
- Broadcast studios and OB van audio
- Conference room and house of worship AV installation
- Theater and performing arts venues
- Permanent commercial AV build-outs (hotels, arenas, campuses)
