The balanced bridging input (100 kΩ) can be wired unbalanced, and the 150 Ω balanced output drives balanced or unbalanced lines of 150 Ω or higher at +4 dBu nominal. A peak overload LED shows excessive pre- or post-EQ levels during setup. The module draws 25 mA from a ground-referenced 24 Vdc supply; RDL recommends the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX power supply\u003c\/a\u003e (international) or PS-24AS (USA).\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-band EQ\u003c\/strong\u003e — Separate low, mid and high controls tailor system response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoice or music shaping\u003c\/strong\u003e — Settings can pass voice-band audio or create a smile curve for music.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridging input\u003c\/strong\u003e — The 100 kΩ input connects balanced or unbalanced.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak overload LED\u003c\/strong\u003e — The LED flags excessive levels before or after EQ.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow noise and distortion\u003c\/strong\u003e — Active circuitry provides clean equalization.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025796165868,"sku":"ST-EQ3","price":142.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/st-eq3.jpg?v=1793583901","url":"https:\/\/creationnetworks.net\/products\/rdl-st-eq3","provider":"Creation Networks","version":"1.0","type":"link"}
