What is this BS EN 61603-2 - Transmission systems for audio wideband and related signals about?
BS EN 61603-2 discusses transmission systems for audio and/or video and related signals using infra-red radiation with a focus on transmission systems for audio wideband and related signals.
BS EN 61603-2 is the second part of the BS EN 61603 multi-series on transmission systems for audio and/or video and related signals that give methods for measuring and specifying those characteristics of wideband audio IR transmission systems. Interface (matching) values and other system characteristics are also covered.
BS EN 61603-2 replaces Chapter 1 of IEC 60764, which covers only two carrier frequencies for analogue audio signals, and which does not cover digital audio.
Who is BS EN 61603-2 - Transmission systems for audio wideband and related signals for?
BS EN 61603-2 on transmission systems for audio wideband and related signals is useful for:
- Manufacturers of products that provide audio output (televisions, phones)
- Audio equipment manufactures
- Audio programmers
- Music producers
- Sound technicians
- Recording and dubbing studios
Why should you use BS EN 61603-2 - Transmission systems for audio wideband and related signals?
New designs of audio wideband systems for analogue transmission by frequency modulation are use the subcarrier frequency ranges 0 MHz (formally) to 1 MHz and 2 MHz to 6 MHz. The transmitter and radiator form a small unit, sometimes further combined with a microphone to form a single unit.
BS EN 61603-2 allows systems that make different economic use of the available bandwidth to be described in order that conclusions regarding interference and compatibility can be drawn.
BS EN 61603-2 discusses an explanation of terms and general information, transmitter, system considerations, general conditions for measurements, characteristics to be specified, and their methods of measurement, interface (matching) values, performance requirements, and recommendations.
Overall, the guidelines of BS EN 61603-2 help you to identify the characteristics of transmission systems for audio wideband and related signals and evaluate their performance.
