{"product_id":"atlasied-tsd-rl21","title":"AtlasIED TSD-RL21 Two Channel Mic Line Mixer for Paging and BGM","description":"\u003cp\u003eThe AtlasIED TSD-RL21 is a compact 2x1 mic\/line mixer designed for system integrators and AV installers who need reliable multi-source mix control in permanent installed sound environments. Channel one is dipswitch-configurable at the rear panel for mic or line level input, while channel two provides a stereo summing RCA input suited for background music sources. Both inputs are controlled via front-panel knobs with optional security covers, allowing the unit to be deployed in publicly accessible locations such as retail spaces, hospitality venues, conference centers, football stadiums, and gymnasiums without risk of unauthorized adjustment.\u003c\/p\u003e\u003cp\u003eWhere the TSD-RL21 separates itself from generic small-format mixers is its remote level control capability. By pairing with an AtlasIED AAVC-10K decorative wall plate or equivalent, installers can assign remote control to either the entire mix bus or the RCA input independently — giving facility operators intuitive zone-level management without touching the rack. The high-gain balanced mono output is designed to drive long cable runs common in installed AV infrastructure, and the removable Phoenix-style I\/O connectors streamline field termination. As part of the AtlasIED Time Saving Devices ecosystem, a single 24VDC power supply can power multiple TSD units simultaneously, reducing infrastructure cost and rack space. Power supply is sold separately; the TSD Power Calculator should be used to size multi-unit installations correctly.\u003c\/p\u003e","brand":"Atlas Sound, L.P. - Mitek","offers":[{"title":"Default Title","offer_id":52445851123896,"sku":"20022","price":287.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/20022_ATLAS-TSD-RL21_ALT03sqr.jpg?v=1783458102","url":"https:\/\/soundpro.com\/products\/atlasied-tsd-rl21","provider":"SoundPro","version":"1.0","type":"link"}
