The line amp is the one used across the 1A family: wide-bandwidth, tube-based, on 12AU7, 12AX7 and 6X4. The differences sit in the passive section, and they are functional rather than cosmetic: reshaped low-frequency curves, two extra peak centres, and something the 1A family does not have at all, high-frequency shelf boost.\u003c\/p\u003e\n\u003ch3\u003eA shelf on top, not only a peak\u003c\/h3\u003e\n\u003cp\u003eThe 1A and 1A3 lift highs with a peak curve only, so the response falls away again above the chosen centre. The EQP-1S adds shelf boost with 5 and 10 kHz corners, up to 14 dB, which raises the whole top end and stays raised. For vocals, strings and a mix bus that is a different tool from a 10 kHz peak: it adds air across the range instead of emphasising one band. Because both sections operate at once, you can hold the shelf as a general tilt and use the peak separately to place presence at 3 or 5 kHz.\u003c\/p\u003e\n\u003ch3\u003eTwo extra centres where the voice lives\u003c\/h3\u003e\n\u003cp\u003ePeak boost offers nine centres, since 1 and 2 kHz join the set inherited from the 1A. That band decides vocal intelligibility and whether a guitar cuts through a backing track, and the 1A family had no access to it at all. The low curves move up to 30, 40, 70 and 100 Hz, giving a higher point of leverage than the 20 Hz of the 1A and working better on material where the lowest octave is already occupied. Low boost and attenuation still act on the same frequency simultaneously, so the classic simultaneous lift-and-cut settings remain available.\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\u003e3U chassis with blue front panel\u003c\/li\u003e\n\u003cli\u003eHigh-frequency shelf boost with 5 and 10 kHz corners, absent from the 1A family\u003c\/li\u003e\n\u003cli\u003eNine high-frequency peak centres, including 1 and 2 kHz\u003c\/li\u003e\n\u003cli\u003eLow-frequency curves shifted to 30, 40, 70 and 100 Hz\u003c\/li\u003e\n\u003cli\u003eSimultaneous low-frequency boost and attenuation at the same frequency\u003c\/li\u003e\n\u003cli\u003eThe same wide-bandwidth line amp as the EQP-1A and EQP-1A3\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: 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\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: 3U (5.25 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Pultec","offers":[{"title":"Default Title","offer_id":54598605865297,"sku":"28535","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/PultecEQP-1SProgramEqualizer1.jpg?v=1786975213","url":"https:\/\/wrdtunes.com\/products\/pultec-eqp-1s-program-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
