The \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-rc4st\"\u003eD-RC4ST remote control\u003c\/a\u003e provides four-button wall selection. All switching is solid state, with off-channel attenuation above 85 dB at 1 kHz and 15 Hz to 40 kHz (±0.5 dB) response. A SLAVE output drives a second ST-SX4 for stereo, and the module draws 45 mA from a ground-referenced 24 Vdc supply such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX power supply\u003c\/a\u003e or PS-24AS (USA).\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-input selection\u003c\/strong\u003e — One of four unbalanced sources feeds the output, or all can be off.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-pair remote control\u003c\/strong\u003e — Selection runs over one control terminal and ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid-state switching\u003c\/strong\u003e — All-electronic switching gives more than 85 dB off-channel attenuation at 1 kHz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStereo slave capability\u003c\/strong\u003e — A SLAVE output links a second switcher for stereo.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistors supplied\u003c\/strong\u003e — The control resistors needed for selection come with the module.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025797378284,"sku":"ST-SX4","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/st-sx4.jpg?v=1793583960","url":"https:\/\/creationnetworks.net\/products\/rdl-st-sx4","provider":"Creation Networks","version":"1.0","type":"link"}
