Beyond the controls, Pulse Techniques made one change to the curves themselves: the 6 kHz peak centre gives way to the 16 kHz centre familiar from the 1A family. The result is the only Pultec that combines a 16 kHz air band with full 5 and 10 kHz shelf boost in one chassis.\u003c\/p\u003e\n\u003ch3\u003eAir and shelf without choosing between them\u003c\/h3\u003e\n\u003cp\u003eThe 1A family has the 16 kHz peak but no high-frequency shelf boost. The 1S family has the 5 and 10 kHz shelf but originally carried a 6 kHz centre where the 16 kHz would be. For mastering that forced a choice between two ways of opening the top: a gentle tilt across the whole band, or air added above the material. The EQM-1S has both on the same panel, and both sections work at once, so you can raise the shelf by half a decibel across the top and add 16 kHz separately wherever the mix reads dark.\u003c\/p\u003e\n\u003ch3\u003eHalf a decibel you can repeat in both channels\u003c\/h3\u003e\n\u003cp\u003eThe switches give 0.5 dB per step through the first half of rotation, with step size growing beyond 50%, so the full 16-20 dB range stays available for more aggressive track work. In mastering, though, what counts most is that a setting is a number: you can write it down, return to it after checking a reference, and dial it identically into the second unit of a pair. With nine peak centres, two shelf corners and a separate attenuator, the number of combinations is large enough that working on potentiometers without documentation stops being repeatable after the first day.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMastering version of the EQP-1S in a 3U chassis\u003c\/li\u003e\n\u003cli\u003e16 kHz peak centre in place of the original 6 kHz\u003c\/li\u003e\n\u003cli\u003e5 and 10 kHz high shelf boost available alongside the 16 kHz peak\u003c\/li\u003e\n\u003cli\u003e21-position ELMA switches instead of potentiometers, 11-position bandwidth switch\u003c\/li\u003e\n\u003cli\u003eFull-range progressive taper: 0.5 dB per step across the 0-5 dB range\u003c\/li\u003e\n\u003cli\u003eNine high-frequency peak centres, including 1 and 2 kHz\u003c\/li\u003e\n\u003cli\u003eLow curves at 30, 40, 70 and 100 Hz with simultaneous boost and cut\u003c\/li\u003e\n\u003cli\u003eRepeatable settings and unit-to-unit matching for stereo work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: passive program equalizer with tube line amplifier, stepped controls\u003c\/li\u003e\n\u003cli\u003eLow shelf boost: 30, 40, 70, 100 Hz, 0-13.5 dB\u003c\/li\u003e\n\u003cli\u003eLow shelf attenuation: 30, 40, 70, 100 Hz, 0-17.5 dB\u003c\/li\u003e\n\u003cli\u003eHigh peak boost: 1, 2, 3, 4, 5, 8, 10, 12, 16 kHz, 0-18 dB\u003c\/li\u003e\n\u003cli\u003eHigh shelf boost: 5, 10 kHz, 0-14.5 dB\u003c\/li\u003e\n\u003cli\u003eHigh shelf attenuation: 5, 10, 20 kHz, 0-16 dB\u003c\/li\u003e\n\u003cli\u003eControls: 21-position switches, 11-position bandwidth switch\u003c\/li\u003e\n\u003cli\u003eInput impedance: approx. 600 Ohms, output approx. 50 Ohms\u003c\/li\u003e\n\u003cli\u003eNoise: 92 dB below +10 dBm\u003c\/li\u003e\n\u003cli\u003eDistortion: 0.15% max at +10 dBm into 600 Ohms\u003c\/li\u003e\n\u003cli\u003eAmplifier response: 20 Hz to 20 kHz, +\/- 0.5 dB\u003c\/li\u003e\n\u003cli\u003eTubes: 12AU7, 12AX7, 6X4 (one each)\u003c\/li\u003e\n\u003cli\u003eHeight: 3U (5.25 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Pultec","offers":[{"title":"Default Title","offer_id":54598607667537,"sku":"44326","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQM-1SMasteringEqualizer1.jpg?v=1786975124","url":"https:\/\/wrdtunes.com\/de\/products\/pultec-eqm-1s-mastering-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
