This stereo isolation transformer removes ground loops and DC paths between two pieces of audio gear, reducing hum and noise before it reaches your mixer or amplifier.\u003c\/p\u003e\u003cp\u003eComputer grounds are often full of noise from disk activity and data transmission, and many audio cards share that ground with the audio signal. Inserted between the sound card and your studio equipment, Pureformer completely isolates the two grounds and passes only the audio, using high-quality, low-distortion 600 ohm transformers with a flat 20 Hz - 20 kHz response.\u003c\/p\u003e\u003cp\u003eIt is fully passive, needing no AC or battery power. Keep in mind that Pureformer cannot remove noise already mixed into the audio signal, so it is best used to treat ground-related problems at their source.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStereo isolation transformer for sound cards and audio equipment\u003c\/li\u003e\n\u003cli\u003eRemoves ground loops and DC paths that cause hum and signal breakup\u003c\/li\u003e\n\u003cli\u003eHigh-quality, low-distortion 600 ohm audio transformers\u003c\/li\u003e\n\u003cli\u003eRCA line input and output\u003c\/li\u003e\n\u003cli\u003ePassive, no AC or battery power needed\u003c\/li\u003e\n\u003cli\u003eMade in America\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLine In: RCA, 600 ohms, -10 dBu nom\u003c\/li\u003e\n\u003cli\u003eLine Out: RCA, 600 ohms, -10 dBu nom\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 20 Hz - 20 kHz, +\/- 0.1 dB\u003c\/li\u003e\n\u003cli\u003eInsertion Loss: 0.8 dB\u003c\/li\u003e\n\u003cli\u003eSize: 3.6 x 1.8 x 1.3 in (9.2 x 4.6 x 3.3 cm)\u003c\/li\u003e\n\u003cli\u003eWeight: 5 oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JK Audio","offers":[{"title":"Default Title","offer_id":50539914264773,"sku":"JKA-PUR","price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/1-jk-audio-pur_d82ae3da-7ae7-454b-997b-6e407011fe45.jpg?v=1790268515","url":"https:\/\/avlgear.com\/products\/jk-audio-pur-pureformer-stereo-rca-isolation-transformer-hum-eliminator","provider":"AVLGEAR","version":"1.0","type":"link"}
