Overview

SIST EN 300 422-2 V1.3.1:2011 specifies essential requirements for electromagnetic compatibility and radio spectrum management for wireless microphones, including equipment operating within 25 MHz to 3 GHz. This harmonized European Standard ensures wireless audio equipment complies with Article 3.2 of the R&TTE Directive (1999/5/EC), focusing on effective use of the allocated spectrum and minimizing harmful interference. The standard applies to several types of radio equipment that utilize analogue, digital, or hybrid modulation.

Key equipment covered:

• Professional wireless microphone systems (PWMS)
• In ear monitoring systems
• Consumer wireless microphones
• Tour guide systems
• Assistive Listening Devices (personal and public hearing aid systems)

Key Topics

Electromagnetic Compatibility (EMC) and Radio Spectrum Matters (ERM):

• Ensures products minimize electromagnetic interference with other devices, especially in environments with dense radio spectrum use.

Frequency Range:

• Applies to devices operating from 25 MHz to 3 GHz, essential for broad compatibility and regulatory compliance in various European countries.

Transmit Power Limits:

• Maximum output of 250 mW for radio microphones and 500 mW for public hearing aids (in select bands).
• Radio microphones in the 863–865 MHz band are limited to 10 mW.

Equipment Types:

• Encompasses both professional and consumer devices, ensuring all wireless microphones and assistive listening devices meet consistent technical standards.

Testing and Conformance:

• Outlines testing procedures for frequency stability, rated power output, bandwidth usage, and spurious emissions.
• Ensures devices are durable across realistic environmental profiles.

Essential Requirements:

• All equipment must use the allocated spectrum efficiently and avoid causing harmful interference to other users.

Applications

Wireless Microphone Compliance:

• Broadcasters, event organizers, and entertainment venues can confidently deploy devices that meet European regulatory requirements, ensuring high-quality, interference-free performance.

Assistive Listening Solutions:

• Promotes accessibility for individuals with hearing loss, guaranteeing assistive devices operate reliably and do not interfere with other radio-based services.

Tourism and Education:

• Tour guide systems benefit from assured spectrum compatibility, enabling clear communication in museums, historical sites, and guided tours.

Consumer Electronics:

• Manufacturers of consumer-grade wireless microphones and monitoring systems can access the European market by aligning with the harmonized requirements set forth in this standard.

Regulatory Approval:

• Compliance with SIST EN 300 422-2 V1.3.1:2011 supports CE marking and national regulatory approvals within the European Economic Area.

Related Standards

For comprehensive compliance and best practices, consider these related standards:

• EN 300 422-1: Technical characteristics and measurement methods for wireless microphones in the same frequency range.
• ETSI EG 201 399: Guidance on producing harmonized standards for the R&TTE Directive.
• ETSI TR 100 028 & TR 102 215: Recommendations on measurement uncertainties for radio equipment testing.
• Directive 1999/5/EC (R&TTE Directive): Legal framework for placing radio equipment on the European market.

---

By adhering to SIST EN 300 422-2 V1.3.1:2011, manufacturers, distributors, and users ensure wireless audio and assistive devices provide reliable service, minimize interference, and meet essential legal requirements in the radio spectrum. This promotes compatibility, safety, and market access throughout Europe.

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive [i.1]. The
modular structure is shown in EG 201 399 [i.3].

1 Scope
The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz, using
analogue, digital and hybrid (using both analogue and digital modulation) modulation.
The present document applies to the following radio equipment types:
• Professional Wireless Microphone Systems (PWMS);
• in ear monitoring systems;
• consumer radio microphones;
• tour guide systems; and
• Assistive Listening Devices (Aids for the handicapped) comprising personal and public hearing aid systems.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphones
and 500 mW for public hearing aids in the 169,4 MHz to 169,8125 MHz band (erp below 1 GHz and eirp above
1 GHz).
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum power
of 10 mW.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive):
Article 3.2, which states that "…. radio equipment shall be so constructed that it effectively uses the spectrum allocated
to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
