ProCo Sound EC9 Siamese Twin Audio/Power Cable | 25 ft

The ProCo Sound EC9 Siamese Twin is engineered for live sound engineers and production crews who need to deliver both AC power and balanced audio to the same destination without doubling their cable runs. By bonding an IEC-to-Edison power channel with an XLR female-to-male AES/EBU audio channel into one flexible assembly, it dramatically reduces stage clutter and speeds up both setup and teardown on touring and installed systems.

The composite construction uses shielded AC and double-shielded audio conductors to suppress hum and interference across all frequencies under 100 kHz — a critical requirement when running power and audio parallel over longer distances. The rugged yet flexible jacket holds up to repeated coiling and uncoiling in demanding production environments without the stiffness that plagues heavier dual-cable workarounds.

For system techs managing speaker stacks, powered displays, or remote processing racks that require both signal and mains, the EC9 replaces two independent cable runs with a single, manageable assembly. It is the practical choice over running separate power and audio snakes when clean cable management and fast changeovers are operational priorities.
