Wireless Microphones - Audio PMSE up to 3 GHz - Part 1: Audio PMSE Equipment up to 3 GHz - Harmonised Standard for access to radio spectrum
The present document specifies technical characteristics and methods of measurements for audio PMSE equipment operating with up to 250 mW output power on radio frequencies up to 3 GHz (see note 1). NOTE 1: For RF power levels above this, refer to ETSI EN 300 454-1 [i.3]. Audio Programme Making and Special Events (PMSE) equipment within the scope of the present document is used in wireless applications for audio transmission purposes including, but not limited to equipment such as wireless microphones, in-ear monitoring systems, conference systems, talkback systems, tour guide systems, Cognitive PMSE (C-PMSE), Wireless Multichannel Audio Systems (WMAS), and assistive listening devices.
Brezžični mikrofoni - Avdio PMSE na frekvencah do 3 GHz - 1. del: Avdio PMSE oprema na frekvencah do 3 GHz - Harmonizirani standard za dostop do radijskega spektra
Ta dokument določa tehnične lastnosti in merilne metode za avdio PMSE opremo, ki deluje z izhodno močjo do 250 mW na radijskih frekvencah do 3 GHz (glej opombo 1). OPOMBA 1: Za stopnje radiofrekvenčne moči nad to vrednostjo glej standard ETSI EN 300 454-1 [i.3]. Avdiooprema za izdelavo programov in posebne dogodke (PMSE) na področju uporabe tega dokumenta se uporablja v brezžičnih aplikacijah za namene prenosa zvoka, kar med drugim vključuje opremo, kot so brezžični mikrofoni, slušno-monitorni sistemi, konferenčni sistemi, povratnogovorni sistemi, sistemi za turistično vodenje, kognitivna avdiooprema za izdelavo programov in posebne dogodke (C-PMSE), brezžični večkanalski zvočni sistemi (WMAS) in pomožni slušni aparati.
