The make-up gain stage here runs in a balanced push-pull configuration.\u003c\/p\u003e\n\u003ch3\u003eAn equalizer that adds something even when you boost nothing\u003c\/h3\u003e\n\u003cp\u003eA Pultec works differently from an EQ in a DAW: the filters are passive, so they only subtract, and the lost level is made up by a tube gain stage. It is that stage, not the curve, that adds the characteristic density — which is why the unit changes the sound even with the controls set flat.\u003c\/p\u003e\n\u003ch3\u003eThe trick people buy a Pultec for\u003c\/h3\u003e\n\u003cp\u003eYou can boost and cut the same low band at once. The filters have different curves, so instead of cancelling they leave the very bottom lifted and the mud just above it removed. On kick and bass that gives depth without thickness — an effect a parametric EQ cannot simply reproduce.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMono tube program equalizer\u003c\/li\u003e\n\u003cli\u003ePassive circuit in Pultec EQP-1A topology\u003c\/li\u003e\n\u003cli\u003eBalanced push-pull make-up gain stage\u003c\/li\u003e\n\u003cli\u003eSimultaneous boost and cut on the same low band\u003c\/li\u003e\n\u003cli\u003eAudible character even at flat settings\u003c\/li\u003e\n\u003cli\u003eDesigned and built by Mercury Recording Equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: tube program equalizer, passive filters\u003c\/li\u003e\n\u003cli\u003eChannels: 1 (mono)\u003c\/li\u003e\n\u003cli\u003eReference circuit: Pultec EQP-1A\u003c\/li\u003e\n\u003cli\u003eGain stage: tube, balanced push-pull\u003c\/li\u003e\n\u003cli\u003eRevision: MKIV\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Mercury Recording Equipment","offers":[{"title":"Default Title","offer_id":54828328812881,"sku":"60907","price":3999.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/eu-mercury-eq-p1-mkiv-1.jpg?v=1788991611","url":"https:\/\/wrdtunes.com\/products\/mercury-eq-p1-mkiv","provider":"Wired Tunes","version":"1.0","type":"link"}
