Like its original inspiration, favoured by producers and engineers from Chris Lord-Alge to Rick Rubin, the WA-1B delivers that revered “forgiving” musical compression of tube-optical circuitry with speed and control more closely associated with modern dynamics processing. Hand-wired to authentically recreate the sound of a renowned circuit, the WA-1B combines custom large-core transformers from Lundahl Sweden, select tubes from JJ and Tung-Sol, and a premium high-precision optical element for ultra-fast and accurate operation without sacrificing authentic analog warmth.\u003c\/p\u003e \u003ch5\u003eFeatures\u003c\/h5\u003e \u003cul\u003e \u003cli\u003eAccurately recreating world-class Scandinavian compression combining smooth tube-optical warmth with precision controls\u003c\/li\u003e \u003cli\u003eTrue-to-spec 270 volt, 100% discrete analog signal path - handwired with through-hole components\u003c\/li\u003e \u003cli\u003eTransformer-balanced fully floating input and output - Custom-core large transformers from Scandinavian Manufacturer, Lundahl in Sweden\u003c\/li\u003e \u003cli\u003e12AX7 Tung-Sol \u0026amp; JJ 12AU7 tubes\u003c\/li\u003e \u003cli\u003eFrequency response @ -3 dB: 5 Hz to 25 kHz\u003c\/li\u003e \u003cli\u003eSelf-Noise: \u0026lt; -75 dBU @ 30 dB gain\u003c\/li\u003e \u003cli\u003eCMRR: \u0026gt; 60 dB @ 10 kHz\u003c\/li\u003e \u003cli\u003eRatio from 2:1 to 10:1\u003c\/li\u003e \u003cli\u003eVariable Threshold: Off to -40 dBU\u003c\/li\u003e \u003cli\u003eContinuously variable attack and release times: fast-slow\u003c\/li\u003e \u003cli\u003eOutput gain: Off to +30 dBU\u003c\/li\u003e \u003cli\u003eInput impedance: 600Ω\u003c\/li\u003e \u003cli\u003eTwo bus connectors to connect multiple sidechains\u003c\/li\u003e \u003cli\u003eMeter (VU) input, output, or compression amount\u003c\/li\u003e \u003cli\u003eLinear, low-noise power supply with toroidal power transformer\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"manufacturer-site\"\u003e\u003cdiv class=\"container\"\u003e\u003cspan\u003eFor more information, please visit the \u003ca href=\"https:\/\/warmaudio.com\/wa-1b\" target=\"_blank\"\u003emanufacturer's website\u003c\/a\u003e.\u003c\/span\u003e\u003c\/div\u003e\u003c\/div\u003e","brand":"Warm Audio","offers":[{"title":"Default Title","offer_id":41441211842618,"sku":"WAR-WA1B","price":1349.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1764\/4443\/files\/warm-audio-wa1b-tube-opto-compressor-war-wa1b-gsus4-3113126.jpg?v=1780491855","url":"https:\/\/gsus4.com.au\/products\/warm-audio-wa1b-tube-opto-compressor","provider":"Gsus4","version":"1.0","type":"link"}
