Installed between a computer or media player and a grounded amplifier, it cleans up audio in conference rooms, classrooms and AV racks.\u003c\/p\u003e\n\u003ch2\u003eHow does it work?\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ez-hk1.jpg\" alt=\"RDL EZ-HK1 Stereo Audio Hum Killer Isolation Module\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003eInputs and outputs are provided on gold-plated RCA jacks and stereo mini-jacks, so the module also converts between mini-jack and RCA formats. The shield of each input jack is electrically isolated from the case and from the output ground. The output shields connect to the case through a rear-panel ground-lift switch for added flexibility. RDL specifies unity gain, 20 Hz to 20 kHz (±1 dB) frequency response and less than 0.05% THD at 1 kHz.\u003c\/p\u003e\n\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround-loop hum elimination\u003c\/strong\u003e — Transformer isolation removes hum caused by ground loops between the source and a grounded amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA and mini-jack connections\u003c\/strong\u003e — Stereo inputs and outputs on both RCA and mini-jacks also allow conversion between the two formats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch-selectable ground lift\u003c\/strong\u003e — A rear-panel switch lifts the output jack shields from the case when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassive unity-gain circuit\u003c\/strong\u003e — The passive design passes -10 dBV signals at unity gain without a power supply.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePortable or installed\u003c\/strong\u003e — The compact case, sized at 1\/6 rack width, works for portable use or permanent installation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025743409388,"sku":"EZ-HK1","price":125.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/ez-hk1.jpg?v=1793583067","url":"https:\/\/creationnetworks.net\/products\/rdl-ez-hk1","provider":"Creation Networks","version":"1.0","type":"link"}
