Wireless Microphones - Audio PMSE up to 3 GHz - Part 1: Class A Receivers - Harmonised Standard covering the essential requirements of article 3.2 of Directive 2014/53/EU

REN/ERM-TG17-18-C1

Brezžični mikrofoni - Avdio PMSE na frekvencah do 3 GHz - 1. del: Sprejemniki razreda A - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU

Ta dokument zajema minimalne lastnosti, ki so potrebne za čim učinkovitejšo uporabo frekvenčnega spektra, ki je na voljo za avdio PMSE in podporne slušne pripomočke (ALD).
Ta dokument določa minimalne zahtevane lastnosti in merilne metode podpornih slušnih pripomočkov, radijskih mikrofonov in slušno-monitornih sistemov. Ne vključuje nujno vseh lastnosti, ki bi jih lahko potreboval uporabnik, in ne predstavlja nujno najboljšega mogočega delovanja.
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 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.8] ter odločbah ECC [i.10] in ES [i.9] glede nekdanjega pasu ERMES (od 169,4 MHz do 169,8125 MHz), kjer je opredeljena moč 500 mW.
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.10];
• odločbe ECC/DEC/(05)02 [i.11];
• odločbe ES SRD [i.9] ali
• dodatka 10 k priporočilu CEPT/ERC/REC 70-03 [i.7] (glej http://www.erodocdb.dk/);
• odločbe ES 2014/641/EU [i.13].
Za radijske mikrofone so morda potrebne posebne licence, razen če je določeno drugače v odločbi ES SRD, odločbi ECC ali nacionalnih vmesnikih.
Ta dokument zajema naslednje vrste opreme:
• slušno-monitorne sisteme;
• radijske mikrofone;
• brezžične večkanalske zvočne sisteme (WMAS);
• sisteme za vodene oglede.
