SIST EN 300 422-2 V2.1.1:2017
(Main)The present document specifies the technical characteristics and methods of measurement for the following types of
equipment:
a) Assistive Listening Devices (ALDs);
b) Radio Microphones;
c) In-Ear Monitoring Systems;
d) Wireless Multichannel Audio Systems (WMAS);
e) Tour Guide Systems;
with Class B receivers which have reduced performance requirements with respect to sensitivity, adjacent channel
selectivity, and receiver blocking compared to those with Class A receivers. It does not necessarily include all the
characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.
Equipment with Class B receivers will support the operation of fewer wireless audio channels in a given amount of
spectrum than Class A receivers.
The present document applies to equipment operating on radio frequencies up to 3 GHz (as shown in table 1) using
analogue, digital and hybrid (using both analogue and digital) modulation.
The maximum power recommended for equipment covered by this multi-part deliverable is 250 mW for radio
microphones and 10 mW for ALDs.
An exception to this are the Public Hearing Aids defined in the CEPT Report 004 [i.7] and subsequent EC Decision
2005/928/EC [i.9] and EC Decision 2006/771/EC [i.8] on the ex ERMES band (169,4 MHz to 169,8125 MHz) where
500 mW is defined.
The present document covers the essential requirements of Article 3.2 of Directive 2014/53/EU under the conditions
identified in annex A. The present document also covers radio microphones used in the 863 MHz to 865 MHz band,
with a maximum power of 10 mW.
Electromagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-9 [i.4].
National regulations on:
1) maximum power output;
2) licensing status;
will take precedence or those detailed in the latest version of:
• EC Decision 2005/928/EC [i.9];
• ECC/DEC/(05)02 [i.10];
• the EC SRD Decision [i.8]; or
• CEPT/ERC/REC 70-03 [i.6], annex 10 (see http://www.erodocdb.dk/);
• EC Decision 2014/641/EU [i.11].
Unless otherwise stated in the EC SRD Decision, ECC Decision or National Interfaces, Radio Microphones can be
subject to individual licence.
Brezžični mikrofoni - Avdio PMSE na frekvencah do 3 GHz - 2. del: Sprejemniki razreda B - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
Ta dokument določa tehnične karakteristike in merilne metode za naslednje vrste opreme:
a) podporne slušne pripomočke (ALD);
b) radijske mikrofone;
c) slušno-monitorne sisteme;
d) brezžične večkanalske zvočne sisteme (WMAS);
e) sisteme za vodene oglede;
s sprejemniki razreda B, ki imajo zmanjšane zahteve glede učinkovitosti v zvezi z občutljivostjo, selektivnostjo sosednjega kanala in blokiranjem sprejemnika v primerjavi s sprejemniki razreda A. Ne vključuje nujno vseh lastnosti, ki bi jih lahko potreboval uporabnik, in ne predstavlja nujno najboljšega mogočega delovanja.
Oprema s sprejemniki razreda B bo podpirala delovanje manjšega števila brezžičnih avdio kanalov v danem spektru kot sprejemniki razreda A.
Ta dokument se uporablja za opremo, ki deluje na radijskih frekvencah do 3 GHz (kot je prikazano v preglednici 1), z uporabo analogne in digitalne modulacije ter hibridne modulacije, ki uporablja tako analogno kot digitalno modulacijo.
Priporočena največja moč za opremo, ki je zajeta v tem večdelnem dokumentu, je 250 mW za radijske mikrofone in 10 mW za podporne slušne pripomočke.
Izjema so javni slušni aparati, opredeljeni v poročilu CEPT 004 [i.7] ter odločbah ES 2005/928/ES [i.9] in 2006/771/ES [i.8] glede nekdanjega pasu ERMES (od 169,4 MHz do 169,8125 MHz), kjer je opredeljena moč 500 mW.
Ta dokument zajema bistvene zahteve člena 3.2 direktive 2014/53/EU pod pogoji iz dodatka A. Ta dokument zajema tudi radijske mikrofone, ki se uporabljajo v pasu od 863 MHz do 865 MHz z največjo močjo 10 mW.
Zahteve za elektromagnetno združljivost (EMC) obravnava dokument ETSI EN 301 489-9 [i.4].
Nacionalni predpisi, ki zajemajo:
1) največjo izhodno moč;
2) licenčni status;
imajo prednost, ali tisti predpisi, ki so vključeni v najnovejše različice:
• odločbe ES 2005/928/ES [i.9];
• odločbe ECC/DEC/(05)02 [i.10];
• odločbe ES SRD [i.8] ali
• dodatka 10 k priporočilu CEPT/ERC/REC 70-03 [i.6] (glej http://www.erodocdb.dk/);
• odločbe ES 2014/641/EU [i.11].
Za radijske mikrofone so morda potrebne posebne licence, razen če je določeno drugače v odločbi ES SRD, odločbi ECC ali nacionalnih vmesnikih.
