ElectroMagnetic Compatibility and Radio Spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) Standard for Radio Equipment and Services; Part 9: Specific Conditions For Wireless Microphones, Similar Radio Frequency (RF) Audio Link Equipment, Cordless Audio and In-Ear Monitoring Devices
|Publication Date:||1 July 2001|
The present document, together with EN 301 489-1 , covers the assessment of wireless microphones, similar RF audio link equipment, cordless audio and in-ear monitoring, intended for the transmission of music and speech, and associated ancillary equipment, in respect of Electro Magnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of wireless microphones, similar RF audio link equipment, cordless audio and in-ear monitoring are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum.
The present document specifies the applicable EMC tests, the test methods, the limits and the performance criteria for wireless microphones, similar RF audio link equipment, cordless audio, in-ear monitoring and associated ancillary equipment. This equipment can use analogue or digital modulation techniques.
Examples of equipment types covered by the present document are given in annex A.
Other types of transmitters or receivers, which are intended for combined use, with either wireless radio microphones, RF audio link equipment, cordless audio and in-ear monitoring shall be tested to their appropriate EMC standard.
Low quality speech applications as toy microphone, baby phones etc. operating at frequencies below 50 MHZ, occupied bandwidth <25 kHz and operating according CEPT ERC/REC 70-3, annex 1  are excluded from the present document and have to be tested according to EN 301 489-3 .
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 , the provisions of the present document take precedence.
The environmental classification and the emission and immunity requirements used in the present document are as stated in En 301 489-1 , except for any special conditions included in the present document.
