The op-amp is based on the classic API 2520, which is a much different sound from the vacuum tube models, but is preferred by many engineers due to their consistency and crystal clear tone.\u003c\/p\u003e\u003cp\u003eThe low band offers boost and attenuation of 30 Hz, 40 Hz, 70 Hz and 100 Hz. The bandwidth control will shape the EQ response of the higher frequencies from sharp to broad.\u003c\/p\u003e\u003cp\u003eThe 500X has a unique group of frequencies to choose from in the higher band, offering peak boost of 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 8 kHz, 10 kHz, 12 kHz and 16 kHz. On the classic shelving Pultec, you would lose the 16 kHz peak boost, which is a favorite to many engineers on the classic EQP-1a. To combine the best of both worlds, the 500X dropped the 6 kHz peak boost and added back the 16kHz band. You can also choose between two shelving boost frequencies of 5 kHz and 10 kHz.\u003c\/p\u003e\u003cp\u003eAttenuation of higher frequencies are independent from the selected boosted bands and include options for 5 kHz, 10 kHz and 20 kHz.\u003c\/p\u003e\u003ch3 style=\"margin: 1em 0px; padding: 0px; font-family: Arial, Helvetica, sans-serif;\"\u003eEQ Points:\u003c\/h3\u003e\u003cul style=\"margin: 1em 0px; padding: 0px 0px 0px 40px; list-style-position: initial; list-style-image: initial; font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e30, 40, 70, 100 CPS shelf boost, 0 - 13.5 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e30, 40, 70, 100 CPS shelf attenuate, 0 - 17.5 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e1, 2, 3, 4, 5, 8, 10, 12, 16 KCS peak boost, 0 - 18 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e5, 10 KCS shelf boost, 0 - 14 dB\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e5, 10, 20 KCS shelf attenuate, 0 - 16 dB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"margin: 1em 0px; padding: 0px; font-family: Arial, Helvetica, sans-serif;\"\u003eSpecifications:\u003c\/h3\u003e\u003cul style=\"margin: 1em 0px; padding: 0px 0px 0px 40px; list-style-position: initial; list-style-image: initial; font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eAmplifier: 20 CPS to 20 KCS; +0, -1 dB ref 1 KCS, including input\/output transformers\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eInput Transformer: 600 Ohms\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eNoise: Below -80 dBm\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eOutput Level: +21 dBm maximum\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eOutput Transformer: 600 Ohms\u003c\/li\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003eDistortion: ≤ 0.15% at 10 dBm into 600 Ohms\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pultec","offers":[{"title":"Default Title","offer_id":44450812035175,"sku":"172244","price":1295.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/pultec-eqp-500x-program-eq-50899-used_172244_1_f0435fe7-d9de-47f1-891b-beafa0029bc6.jpg?v=1787094627","url":"https:\/\/vintageking.mom\/products\/pultec-eqp-500x-program-eq-50899-used","provider":"Vintage King","version":"1.0","type":"link"}
