Overview

SIST EN 300 422-2 V1.4.1:2015 is a harmonized European standard developed by the Slovenian Institute for Standardization (SIST), based on the ETSI EN 300 422-2 V1.4.1. The standard focuses on electromagnetic compatibility (EMC) and radio spectrum matters for wireless microphones operating within the 25 MHz to 3 GHz frequency range. It addresses compliance with the essential requirements of Article 3.2 of the R&TTE Directive 1999/5/EC, ensuring efficient spectrum use and the avoidance of harmful interference.

This standard applies to a variety of wireless audio transmission equipment, including:

• Professional Wireless Microphone Systems (PWMS)
• In-ear monitoring systems
• Consumer radio microphones
• Tour guide systems
• Assistive Listening Devices (ALDs), covering both personal and public hearing aids

It covers equipment using analogue, digital, and hybrid modulation methods and sets maximum power recommendations for devices, promoting coexistence and regulatory compliance in the increasingly crowded radio spectrum.

Key Topics

1. Frequency Range and Modulation

• Defines the applicable frequency range: 25 MHz to 3 GHz
• Includes support for analogue, digital, and hybrid (analogue/digital) modulation

2. Equipment Types

• Encompasses professional and consumer wireless microphone solutions
• Targets applications for live performance, broadcast, education, and accessibility

3. Power Output Recommendations

• Maximum for radio microphones: 250 mW
• Maximum for public hearing aids (in 169.4 MHz to 169.8125 MHz band): 500 mW
• Special category for the 863-865 MHz band: maximum 10 mW

4. Technical Requirements

• Frequency stability and output power limits
• Control of necessary bandwidth for efficient spectrum use
• Restrictions and limits on spurious emissions to minimize interference
• Standardized test methods for compliance assessment

5. Harmonization with the R&TTE Directive

• Aligns with Article 3.2 to support efficient and interference-free use of terrestrial and space communications resources

Applications

SIST EN 300 422-2 V1.4.1:2015 is crucial for manufacturers, system integrators, and service providers operating or deploying wireless audio solutions in Europe. Practical applications include:

• Live Events and Broadcast: Ensures wireless microphones and in-ear monitors used by performers, speakers, and crew meet legal requirements, prevent interference, and deliver reliable audio transmission.
• Education and Conferencing: Facilitates compliant tour guide and lecture systems, supporting clear audio in classrooms, auditoriums, and guided tours.
• Accessibility: Guarantees that assistive listening devices, including public hearing aids, operate within regulated spectrum and power limits, supporting users with hearing impairments.
• Consumer Devices: Ensures consumer-grade wireless microphones are safe and compatible with other wireless equipment.

Through compliance, organizations can achieve:

• Regulatory approval and market entry in EU countries
• Reduced risk of harmful interference
• Protection for end-users and professional operations

Related Standards

For comprehensive compliance and system design, the following standards are relevant:

• EN 300 422-1: Technical characteristics and testing methods for wireless microphones in the same frequency range
• Directive 1999/5/EC (R&TTE Directive): Core EU legislation on radio and telecommunications terminal equipment, now replaced by the RED Directive
• ETSI EG 201 399: Guidance on harmonized standards under the R&TTE Directive
• ETSI TR 100 028 and ETSI TR 102 215: Address measurement uncertainties for RF characteristics

Keywords: wireless microphones, electromagnetic compatibility, radio spectrum, R&TTE Directive, professional audio, in-ear monitors, assistive listening devices, spectrum efficiency, EMC compliance, spectrum regulation.

Adhering to SIST EN 300 422-2 V1.4.1:2015 ensures reliable, high-quality wireless audio experiences, protects spectrum resources, and supports legal market access across Europe.
