ETSI EN 300 422-3

ETSI EN 300 422-3 specifies the technical characteristics and methods of measurement for the following types ofequipment:

• 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, adjacentchannel selectivity, and receiver blocking compared to those with Class A receivers. It does not necessarily include allthe characteristics that may be required by a user, nor does it necessarily represent the optimum performanceachievable. Equipment with Class C receivers will support the operation of fewer wireless audio channels in a givenamount of spectrum than Class A or Class B receivers.
