SRPS EN 300 422-3 V2.1.1:2017

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

Scope

The present document specifies the technical characteristics and methods of measurement for the following types of equipment: 1) Assistive Listening Devices; 2) Radio Microphones; 3) In-ear Monitoring Systems; 4) WMAS (Wireless Multichannel Audio Systems; 5) Tour Guide Systems; with Class C receivers which have significantly 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 C receivers will support the operation of fewer wireless audio channels in a given amount of spectrum than Class A or Class B receivers.
