In 1971 Gene Shenk and Ollie Summerlin rearranged the controls and components of the 3U model to fit a chassis a third shorter without altering the circuit. The original brochures said it outright: same parts, same specs. This was the first model Pulse Techniques put back into production.\u003c\/p\u003e\n\u003ch3\u003eEight channels of Pultec where six used to fit\u003c\/h3\u003e\n\u003cp\u003eThe difference between 3U and 2U stops being cosmetic the moment you count rack space. A room that wants passive equalization on every bus channel fits a third more units into the same rack at 3.5 inches of height. That matters for stereo work, where every band needs a matched pair, and it matters when the equalizer lives permanently in one bus insert. The circuit and the 12AU7, 12AX7 and 6X4 tube complement are identical to the EQP-1A, so the choice comes down to space and which panel you prefer looking at.\u003c\/p\u003e\n\u003ch3\u003eCurves that do not fight each other\u003c\/h3\u003e\n\u003cp\u003eThe low section boosts and attenuates at the same frequency, and most of what this equalizer is used for rests on that behaviour. Up to 13.5 dB of boost at 60 or 100 Hz against up to 17.5 dB of cut leaves a bottom end with mass and a visibly cleared band above it, which tidies kick and bass without reaching for a high-pass filter. The high section works independently: seven peak centres from 3 to 16 kHz with a bandwidth control, plus a separate shelf attenuator at 5, 10 or 20 kHz. You can lift presence at 5 kHz and pull excess air above 10 kHz in the same pass.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePassive equalization network with a tube line amp restoring level\u003c\/li\u003e\n\u003cli\u003e2U chassis with brushed aluminium front panel\u003c\/li\u003e\n\u003cli\u003eSame components and specifications as the 3U EQP-1A\u003c\/li\u003e\n\u003cli\u003eSimultaneous low-frequency boost and attenuation at the same frequency\u003c\/li\u003e\n\u003cli\u003eFour low-frequency centres: 20, 30, 60 and 100 Hz\u003c\/li\u003e\n\u003cli\u003eSeven high-frequency peak centres from 3 to 16 kHz with bandwidth control\u003c\/li\u003e\n\u003cli\u003eHigh shelf attenuation at 5, 10 and 20 kHz\u003c\/li\u003e\n\u003cli\u003e600 Ohm input and output transformers\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\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\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":54598605209937,"sku":"28533","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQP-1A3ProgramEqualizer-StandardVersion1.jpg?v=1786975253","url":"https:\/\/wrdtunes.com\/de\/products\/pultec-eqp-1a3-program-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
