Inspired by classic vintage equalizer designs, it combines passive EQ components, transformer-balanced input and output stages, and tube amplification to add openness, density, and presence across a wide range of sources.\u003c\/p\u003e \u003ch2\u003eTegeler Classic Equalizer EQP 1 Competitive Differences\u003c\/h2\u003e \u003cul\u003e \u003cli\u003ePassive EQ design with tube stage and input\/output transformers for smooth, musical tone shaping\u003c\/li\u003e \u003cli\u003eSelectable low boost\/cut, high boost with variable bandwidth, and high-frequency attenuation for classic analog EQ control\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eTegeler Classic Equalizer EQP 1 Description\u003c\/h2\u003e \u003cp\u003eThe \u003cstrong\u003eTegeler Classic Equalizer EQP 1\u003c\/strong\u003e is designed for users who want more than corrective equalization. It delivers the kind of broad, musical shaping that helps vocals sound silky, instruments stand out more clearly in a mix, and low-frequency material gain weight without becoming muddy or boomy. This makes it a strong choice for mix bus processing, individual instruments, and tone enhancement during recording.\u003c\/p\u003e \u003cp\u003eIts sonic character comes from a passive equalizer section built with capacitors and inductors, following the approach of revered vintage analog equalizers. The EQ layout includes low-frequency boost and attenuation, high-frequency boost with adjustable bandwidth, and a separate high-frequency cut section, giving users an intuitive way to shape tone without overcomplicating the workflow.\u003c\/p\u003e \u003cp\u003eBeyond the EQ curves themselves, the tube stage and transformer-balanced signal path contribute a noticeable sense of depth and polish. Even with the equalizer settings left untouched, the analog circuit can add density, presence, and a more rounded top end, while helping the low end feel more defined and transparent.\u003c\/p\u003e \u003cp\u003eWith balanced input and output connections, an internal power supply, and a 2U rackmount design, this hardware EQ fits easily into professional studio setups. It is well suited for engineers looking for a classic analog equalizer that can add both tonal control and desirable signal-path character.\u003c\/p\u003e \u003ch3\u003eClassic Equalizer EQP 1 Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003ePassive tube equalizer\u003c\/li\u003e \u003cli\u003eVintage-style passive EQ design using capacitors and inductors\u003c\/li\u003e \u003cli\u003eLow boost and attenuation frequency selections: 20 Hz, 30 Hz, 60 Hz, 100 Hz\u003c\/li\u003e \u003cli\u003eHigh boost frequency selections: 3 kHz, 4 kHz, 5 kHz, 6 kHz, 8 kHz, 10 kHz, 12 kHz, 16 kHz, 20 kHz\u003c\/li\u003e \u003cli\u003eVariable bandwidth on high boost section\u003c\/li\u003e \u003cli\u003eHigh attenuation frequency selections: 5 kHz, 10 kHz, 20 kHz\u003c\/li\u003e \u003cli\u003eBalanced input and output\u003c\/li\u003e \u003cli\u003eInput transformer\u003c\/li\u003e \u003cli\u003eOutput transformer\u003c\/li\u003e \u003cli\u003eTube stage\u003c\/li\u003e \u003cli\u003eBypass switch\u003c\/li\u003e \u003cli\u003eInternal power supply\u003c\/li\u003e \u003cli\u003e2U rackmount format\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eClassic Equalizer EQP 1 Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eType: Passive Tube Equalizer\u003c\/li\u003e \u003cli\u003eFrequency Response: 20 Hz - 22 kHz\u003c\/li\u003e \u003cli\u003eMaximum Input Level: +20 dBu\u003c\/li\u003e \u003cli\u003eInput Impedance: 2.4 kOhm\u003c\/li\u003e \u003cli\u003eOutput Impedance: \u0026lt; 600 Ohm\u003c\/li\u003e \u003cli\u003eMaximum Output Level: +22 dBu\u003c\/li\u003e \u003cli\u003eDynamic Range: 95 dB\u003c\/li\u003e \u003cli\u003eVoltage: 230 V~\/50 Hz or 115 V~\/60 Hz\u003c\/li\u003e \u003cli\u003eFuse: 500 mA slow-blow\u003c\/li\u003e \u003cli\u003eMaximum Power Consumption: \u0026lt; 25 W\u003c\/li\u003e \u003cli\u003eDimensions: 3.47 x 19.02 x 9.84 in\u003c\/li\u003e \u003cli\u003eDimensions: 88.1 x 483 x 250 mm\u003c\/li\u003e \u003cli\u003eRack Size: 2U\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat's In The Box\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eTegeler Classic Equalizer EQP 1\u003c\/li\u003e \u003c\/ul\u003e","brand":"Tegeler","offers":[{"title":"Default Title","offer_id":52109295190298,"sku":"117139","price":1999.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/tegeler-classic-equalizer-eqp-1--passive-tube-equalizer-with-vintage-eq-curves--transformer-balanced-analog-tone-shaping_7d2fd8af-1ec8-41e2-ba86-59917d2f29e8.webp?v=1776787974","url":"https:\/\/squarecable.com\/products\/tegeler-classic-equalizer-eqp-1-passive-tube-equalizer-with-vintage-eq-curves-transformer-balanced-analog-tone-shaping","provider":"SquareCable","version":"1.0","type":"link"}
