Overview
EN 61603-2:1997/A1:2004 (also published as IEC 61603-2 with CENELEC endorsement) specifies principles and requirements for the transmission of audio wide band and related signals using infra‑red (IR) radiation. Part 2 of the IEC/EN 61603 series focuses on IR transmission systems for wideband audio (analog and related signals). Amendment A1 (2004) updates the original 1997 edition and clarifies the treatment of digital audio (digital audio transmission was removed from this part and is now covered by IEC 61603-8-1).
Key topics and requirements
The standard addresses high‑level technical and regulatory topics relevant to IR audio systems, including:
- System scope and definitions for infra‑red transmission of wideband audio and related analog signals.
- Design and interoperability principles for IR transmitters, receivers and system components to ensure consistent audio performance and reliable link operation.
- Performance and quality considerations such as audio bandwidth and fidelity expectations for wideband audio applications (general guidance rather than prescriptive numeric values in the extract).
- Amendment notes: removal of digital audio subclause (see IEC 61603-8-1 for digital audio).
- Standards governance: European adoption and national implementation timelines (A1 approved 2004-09-01; national implementation by 2005-09-01; conflicting standards withdrawn by 2007-09-01).
Applications
EN 61603-2 is applicable where reliable, short‑range, line‑of‑sight infra‑red audio transmission is preferred or required. Typical use cases:
- Assistive listening systems in theatres, lecture halls and museums (IR hearing assistance).
- In‑room audio distribution for conferencing systems, translation/interpretation services and guided tours.
- Secure or RF‑restricted environments (medical facilities, aircraft cabins, secure meeting rooms) where RF emissions are limited and IR offers an alternative.
- Professional AV installations requiring predictable, low‑interference wideband audio links.
Who should use this standard
- Audio and multimedia equipment manufacturers designing IR transmitters/receivers and accessory components.
- System integrators and AV designers specifying IR audio distribution and assistive listening solutions.
- Test laboratories, certification bodies and regulatory authorities assessing compliance and interoperability.
- Facility operators and procurement teams selecting IR‑based audio systems for public or sensitive spaces.
