{"product_id":"pultec-eqm-1a3-program-equalizer","title":"Pultec EQM-1A3 Program Equalizer","description":"\u003cdiv lang=\"en\"\u003e\n\u003cp\u003e\u003cstrong\u003ePultec EQM-1A3 Program Equalizer\u003c\/strong\u003e in its mastering version puts the EQP-1A3 curves and fully stepped controls into a 2U chassis. The boost and attenuation potentiometers give way to 21-position ELMA switches, bandwidth moves to an 11-position switch, and every step is loaded with precision metal film resistors. The signal path stays passive, with a tube line amp on 12AU7, 12AX7 and 6X4 restoring the level.\u003c\/p\u003e\n\u003ch3\u003eA stereo bus pair in four rack units\u003c\/h3\u003e\n\u003cp\u003eEqualizing a stereo bus takes two units, and with 3U models that means six rack units spent on one band of equalization. The 2U version brings that down to four, which in a built-out mastering position decides whether the pair fits alongside the compressor, converters and monitor controller at all. Curves, components and specifications are identical to the 3U EQM-1A, so the difference shows up only in rack inches and in how the panel looks.\u003c\/p\u003e\n\u003ch3\u003eFine steps early, full range at the end\u003c\/h3\u003e\n\u003cp\u003eThe full-range progressive taper gives 0.5 dB per step through the first half of rotation, and beyond 50% the steps grow to 1 or 2 dB. That solves a specific conflict: mastering asks for half-decibel moves while work on a single track needs the full 18-20 dB, and one scale has to serve both. Worth remembering is that in a Pultec the low boost and attenuation sections interact, so with simultaneous lift and cut the effective step size shifts away from its nominal value. Which is precisely why a repeatable setting described by a number is worth more here than on an equalizer with independent bands.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEQP-1A3 curves and signal path in a 2U chassis\u003c\/li\u003e\n\u003cli\u003e21-position ELMA switches in place of boost and attenuation potentiometers\u003c\/li\u003e\n\u003cli\u003e11-position bandwidth switch\u003c\/li\u003e\n\u003cli\u003ePrecision metal film resistors giving each control its own taper\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\u003eA stereo bus pair occupies 4U instead of the 6U needed by 3U models\u003c\/li\u003e\n\u003cli\u003eSetting-for-setting matching between units in stereo work\u003c\/li\u003e\n\u003cli\u003eSimultaneous low-frequency boost and attenuation at the same frequency\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: 20, 30, 60, 100 Hz, 0-13.5 dB\u003c\/li\u003e\n\u003cli\u003eLow shelf attenuation: 20, 30, 60, 100 Hz, 0-17.5 dB\u003c\/li\u003e\n\u003cli\u003eHigh peak boost: 3, 4, 5, 8, 10, 12, 16 kHz, 0-18 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\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 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: 2U (3.5 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Pultec","offers":[{"title":"Default Title","offer_id":54598605013329,"sku":"28530","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQM-1A3ProgramEqualizer-MasteringVersion1.jpg?v=1786975281","url":"https:\/\/wrdtunes.com\/de\/products\/pultec-eqm-1a3-program-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
