Overview
EN 60268-12:1995/A2:1995 (CLC adoption of the IEC amendment) updates Part 12 of the IEC 60268 series: application of connectors for broadcast and similar use. This amendment clarifies contact designation, adds a dedicated section for high-level connectors, and reorganizes connection and polarity clauses to improve interoperability in studio and broadcast audio systems.
The document is intended for manufacturers, system integrators and audio engineers working with connector selection, wiring and on-site installation of amplifier–loudspeaker and low-level signal circuits.
Key Topics
- Section reorganization and clause changes: the amendment inserts a new title for clause 8 (Connection data), renumbers the existing polarity clause, and adds Section 3 covering high-level connectors.
- Low-level connectors: tables define contact arrangements and applications for low-level circular and concentric connectors, plus associated contact designation conventions.
- High-level connectors: new Section 3 (clauses 10 and 11) specifies types and applications for connectors used between amplifiers and loudspeakers (see Table V) and provides connection data for multi-amp configurations (see Table VI).
- Polarity and connection data: polarity clause was renumbered (former clause 8 → now clause 9) and connection data tables were reworked to reference the updated sections.
- Cordset guidance: the amendment notes that cordsets (except permanent installations) should either have conductors matching the connector contact count (commonly four or eight) or be marked to indicate which contacts are connected.
Applications
This amendment is directly applicable to:
- Broadcast studios and OB (outside-broadcast) equipment where standard connector assignment and polarity are critical.
- Amplifier-to-loudspeaker wiring schemes including bi-amp, tri-amp and multi-amp loudspeaker systems - Table VI provides contact mappings and return/signal allocations for these configurations.
- Equipment manufacturers specifying connector types, contact designation and cordset requirements to ensure interoperability across products and installations.
Practical benefits include clearer installation guidance, reduced wiring errors, consistent polarity handling and simplified cross-vendor compatibility.
Related Standards
- IEC 60268 series (general sound system equipment standards) - Part 12 complements other parts by focusing on connectors and application guidance.
- Relevant connector specifications under IEC SC 48B (referenced for IEC type designations used in Table V).
For implementers, this amendment is a focused update that improves clarity on connector application, wiring and contact designation for professional broadcast and studio audio environments. Consult the full EN/IEC text and the referenced tables (I–VI) for specific contact arrangements and connection assignments.
