What separates it from the related EQ-P1 is the make-up gain stage: here it runs single-ended, which you hear as a different, more forward kind of saturation.\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\u003eSingle-ended instead of push-pull, and what follows from it\u003c\/h3\u003e\n\u003cp\u003eA single-ended stage does not cancel even harmonics the way a balanced push-pull does. In practice that means more audible colour and less neutrality — exactly what you reach for a tube for on vocal midrange, on guitars and on a parallel mix bus. If you already own the EQ-P1, the EQ-H1 complements it rather than replacing it.\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 EQH topology\u003c\/li\u003e\n\u003cli\u003eSingle-ended gain stage\u003c\/li\u003e\n\u003cli\u003eMore pronounced colour than the push-pull version\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 EQH\u003c\/li\u003e\n\u003cli\u003eGain stage: tube, single-ended\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":54828328780113,"sku":"60906","price":3399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/eu-mercury-eq-h1-mkiv-1.jpg?v=1788991611","url":"https:\/\/wrdtunes.com\/fr\/products\/mercury-eq-h1-mkiv","provider":"Wired Tunes","version":"1.0","type":"link"}
