It bundles the server, receivers and listening accessories a venue needs to meet an ADA assistive listening obligation over its existing wireless network, rather than requiring a separate RF or infrared distribution layer. The 4-receiver count suits a venue sizing its fleet against seat count. Specifying a system rather than assembling components removes the risk of a missing accessory at commissioning.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eAssistive listening obligations are usually expressed as a receiver count derived from seating capacity, which is why Listen packages these systems by receiver quantity rather than by room type.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/LWS-4_System-Composite_2023-WEB-T.png?v=1787627392\" alt=\"Listen Technologies LWS-04B-W1 ListenWIFI system with 4 receivers\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003cp\u003eThis configuration provides two audio channels and 4 LWR-1050 receivers.
