The basis is the same proven design: a passive equalization network behind an input transformer, and a gain stage built on a genuine API 2520 opamp driving a Triad output transformer. The curve set matches the 1S3, the widest in the line, high-frequency shelf boost included.\u003c\/p\u003e\n\u003ch3\u003eEight channels of Pultec in one rack\u003c\/h3\u003e\n\u003cp\u003eThe rackmount versions take 2U per channel, so passive equalization across a whole drum section means a dozen or more rack units and a separate power supply in every box. A 500-series module occupies one slot, draws from the rack's supply, and lets you assemble a multichannel Pultec setup inside a single 3U enclosure. That changes how tracking sessions work, with passive equalization reaching several microphones at once rather than only the bus. Recording drums, a horn section or several guitars at the same time, the difference between one slot and two rack units per channel decides whether the setup is possible at all.\u003c\/p\u003e\n\u003ch3\u003eThe full curve set with no concession to size\u003c\/h3\u003e\n\u003cp\u003eThe smaller format does not mean a trimmed equalization section. You still get low curves at 30, 40, 70 and 100 Hz with simultaneous boost and cut, nine high peak centres from 1 to 16 kHz, shelf boost with 5 and 10 kHz corners, and shelf attenuation at 5, 10 or 20 kHz. The character of the path is the one engineers describe as punchier with a tighter low end than the tube variant. A maximum output level of +21 dBm and noise below -80 dBm match the rackmount versions exactly.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePassive Pultec equalization in a 500-series module\u003c\/li\u003e\n\u003cli\u003eGenuine API 2520 opamp with a Triad output transformer\u003c\/li\u003e\n\u003cli\u003eCurve set matching the EQP-1S3-SS\u003c\/li\u003e\n\u003cli\u003eHigh-frequency shelf boost with 5 and 10 kHz corners\u003c\/li\u003e\n\u003cli\u003eNine high-frequency peak centres, including 1 and 2 kHz\u003c\/li\u003e\n\u003cli\u003eSimultaneous low-frequency boost and attenuation at the same frequency\u003c\/li\u003e\n\u003cli\u003eOne rack slot per channel instead of 2U in the rackmount version\u003c\/li\u003e\n\u003cli\u003eOutput level to +21 dBm and noise below -80 dBm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: passive program equalizer in 500-series format, solid-state amplifier\u003c\/li\u003e\n\u003cli\u003eGain stage: API 2520 with Triad output transformer\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 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, output 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":54598607733073,"sku":"44327","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQP-500X500SeriesProgramEqualizer1.jpg?v=1786975095","url":"https:\/\/wrdtunes.com\/de\/products\/pultec-eqp-500x-500-series-program-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
