{"product_id":"pultec-eqp-1a3-ss-program-equalizer","title":"Pultec EQP-1A3-SS Program Equalizer","description":"\u003cdiv lang=\"en\"\u003e\n\u003cp\u003e\u003cstrong\u003ePultec EQP-1A3-SS Program Equalizer\u003c\/strong\u003e is the EQP-1A3 with a solid-state gain stage. The front end is identical to the tube version: the same input transformer and the same passive equalization network. Only the way level is restored changes, because in place of tubes there is an API 2520 opamp driving a Triad output transformer, exactly as in the originals from the early 1970s. Pulse Techniques is the only company licensed to use genuine API 2520 opamps.\u003c\/p\u003e\n\u003ch3\u003eA shorter attack on kick, bass and piano\u003c\/h3\u003e\n\u003cp\u003eEngineers describe this version as punchier, with a tighter low end than the tube variant, and that is not a matter of a louder sound but of how the gain stage behaves on transients. On kick, snare, bass and piano it means the attack survives a simultaneous lift at 60 or 100 Hz, so the bottom grows while the hit stays defined. Some rooms keep both variants and reach for the tube version on vocals and buses, the solid-state one on the rhythm section. Output headroom runs to +21 dBm with noise below -80 dBm, so the unit takes hot insert levels without careful gain matching.\u003c\/p\u003e\n\u003ch3\u003eThe same passive network, a different output stage\u003c\/h3\u003e\n\u003cp\u003eThe curves are identical to the tube EQP-1A3, including simultaneous low boost and attenuation at the same frequency. Up to 13.5 dB of boost at 60 Hz against up to 17.5 dB of cut on the same setting produces a bottom with mass and a cleared band directly above it. The high section offers seven peak centres from 3 to 16 kHz with a bandwidth control, plus separate shelf attenuation at 5, 10 or 20 kHz. This same circuit forms the core of the company's 500-series modules, so choosing between versions is a decision about gain-stage character, not about equalization capability.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEQP-1A3 passive equalization network with a solid-state gain stage\u003c\/li\u003e\n\u003cli\u003eGenuine API 2520 opamp with a Triad output transformer\u003c\/li\u003e\n\u003cli\u003eThe only company licensed to use genuine API 2520 opamps\u003c\/li\u003e\n\u003cli\u003eTighter low end and more defined attack than the tube variant\u003c\/li\u003e\n\u003cli\u003eSimultaneous low-frequency boost and attenuation at the same frequency\u003c\/li\u003e\n\u003cli\u003eSeven high-frequency peak centres from 3 to 16 kHz with bandwidth control\u003c\/li\u003e\n\u003cli\u003eOutput level to +21 dBm and noise below -80 dBm\u003c\/li\u003e\n\u003cli\u003eThe same circuit that forms the core of the 500-series modules\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: passive program equalizer with solid-state line amplifier\u003c\/li\u003e\n\u003cli\u003eGain stage: API 2520 with Triad output transformer\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: below -80 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 \/ -1 dB ref 1 kHz, transformers included\u003c\/li\u003e\n\u003cli\u003eMaximum output level: +21 dBm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Pultec","offers":[{"title":"Default Title","offer_id":54598605537617,"sku":"28534","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQP-1A3-SSProgramEqualizer-SolidStateVersion1.jpg?v=1786975224","url":"https:\/\/wrdtunes.com\/fr\/products\/pultec-eqp-1a3-ss-program-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
