It streams to up to 500 concurrent listening devices from a single 1RU rack unit, whether those are ListenWIFI receivers or patrons' own phones. Eight balanced analog inputs on rear terminal blocks take feeds directly from a mixer or DSP. For a commercial assistive listening system in a building with managed Wi-Fi, this replaces the transmitter and antenna infrastructure an RF deployment would need.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eChannel count is the first specification decision. Eight mono channels, or four stereo, covers a main programme feed plus interpretation, audio description or overflow room feeds without a second server.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/LW-210-08_Front_2023-WEB-W.jpg?v=1787627391\" alt=\"Listen Technologies LW-215-08-MH-09 8-channel Wi-Fi audio server\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003cp\u003eInputs are balanced at +4 dBu nominal on one terminal block connector per channel, mounted on the rear panel. Audio is carried at 48 kHz and 16 bits. The network side is a single RJ-45 at 10\/100\/1000 Mbps, with each listening device consuming 125 kbps of audio bandwidth. That figure is the one to take to the network team: 500 concurrent listeners is roughly 62 Mbps of sustained multicast-adjacent traffic, and the wireless design has to carry it.\u003c\/p\u003e\u003cp\u003eThe chassis is 1RU with rack ears included, 45 x 483 x 117 mm, in powder coated stainless steel. Power comes in over USB-C from a 100-240 VAC supply delivering 5 VDC at 2.4 A. Operating range is -10 ºC to +40 ºC, and the unit carries UL, FCC, CE, ROHS and UKCA approvals with a 2 year warranty.\u003c\/p\u003e\u003cp\u003eReceivers are ordered separately: the \u003ca href=\"https:\/\/creationnetworks.net\/products\/listen-technologies-lwr-1050-w0-listenwifi-wi-fi-audio-receiver\"\u003eLWR-1050 ListenWIFI receiver\u003c\/a\u003e or the \u003ca href=\"https:\/\/creationnetworks.net\/products\/listen-technologies-lwr-1050-mh-meetinghouse-wi-fi-audio-receiver\"\u003eMeetinghouse variant\u003c\/a\u003e for venues on that platform.
