34、ntial, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (https:/ipr.etsi.org/). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

Foreword This European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatib
36、ility and Radio spectrum Matters (ERM). The present document has been prepared under the Commissions standardisation request C(2015) 5376 final i.18 to provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation of the laws of the Member State
37、s relating to the making available on the market of radio equipment and repealing Directive 1999/5/EC i.14. Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with the normative clauses of the present document given in table A.1 confers,
38、 within the limits of the scope of the present document, a presumption of conformity with the corresponding essential requirements of that Directive and associated EFTA regulations. The present document is part 1 of a multi-part deliverable covering Wireless Microphones, Audio PMSE, and ALDs up to 3
39、 GHz, as identified below: Part 1: “Class A Receivers; Harmonised Standard covering the essential requirements of article 3.2 of Directive 2014/53/EU“; Part 2: “Class B Receivers; Harmonised Standard covering the essential requirements of article 3.2 of Directive 2014/53/EU“; Part 3: “Class C Receiv

41、ential requirements of article 3.2 of Directive 2014/53/EU“.

43、s (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Executive summary With the introduction of Directive 2014/53/EU i.14, the present multi-part deliverable has been reformatted into multiple parts to acco
44、mmodate the different types of equipment represented, i.e. different receivers for audio Programme Making and Special Events (PMSE) and Assistive Listening Devices (ALD). Part 1 covers Class A receivers. The present document seeks to improve spectrum efficiency and has introduced new technology to a
45、ssist in maximizing the use of available spectrum. The present document seeks to provide a platform for Wideband Multichannel Audio Systems (WMAS). Although the present document covers spectrum up to 3 GHz, it should be emphasized that multi-channel audio PMSE systems used in professional production
46、s are best suited to spectrum under 2 GHz for reasons of propagation and body interaction. Further information on audio PMSE is available in ECC Report 204 i.15. Introduction With the introduction of Directive 2014/53/EU i.14, receiver parameters are now included and the removal of the 9 kHz lower l
47、imit has brought inductive loop systems and receivers into the present document. Inductive loop transmitters are covered within ETSI EN 303 340 i.19 along with test receivers; hearing aids containing inductive loop receivers (often referred to as T coil) are now covered in the present document. The
48、frequency range of the present document has been reduced to accommodate inductive loop receivers. The present document is a testing standard based on spectrum utilization parameters and does not include performance characteristics that may be required by the user nor requirements for interfacing equ
49、ipment. ETSI EN 300 422 was originated in 1991 when Assistive Listening Devices (ALD) were a very small part of the Radio Microphone Industry; in recent years major advances in both the volume and functionality of ALDs has caused a rethink in how to best present the testing regime in a clear and concise manner. After a number of discussions the present document covers audio PMSE as Parts 2 i.20, and 3 i.21, and ALDs as Part 4 i.22.
