EQP-2A Stereo Tube Equalizer
EQP-2A Stereo Tube Equalizer
The most classic passive EQ, now in Stereo!
Mastering Version Now Available
AudioScape is proud to bring you a modern upgrade of one of the world’s most classic EQs, introducing the EQP-2A, the stereo solution for lighting up your mixes or stereo tracks with the electrifying tone of the EQP tube equalizer. Their family of EQPs, which includes their faithfully re-created EQP-A, and the EQP-A Mastering Edition, now adds the EQP-2A Stereo Tube EQ.
The EQP-2A is a Stereo only unit and they still recommend the EQP-A for mono applications and matched pairs of EQP-As for multi mono use.
Pulse Techniques released the EQP-1 in the mid-1950s, with some financial backing from MGM. It was originally intended as a mono “program equalizer”, since stereo playback in recording, broadcast, etc. hadn’t yet become the predominant format. Technology moved forward, but the EQP and it’s variants were so beloved that it remained a single channel processor until phased out in 1981. In practical use, the EQP served beautifully inserted over individual sources, imparting it’s unique tube-tone even when no EQ was applied, but two of them strapped across the stereo bus, or as part of the mastering chain, offered a radiant tone that made the EQP equally as desirable in those applications.
Now, in its original battle-ship grey glory, AudioScape has created the stereo EQP-2A. Absolutely faithful to the original in its component compliment…x2! You get all that incredible mojo and box-tone intrinsic to the EQP family in a format that makes it a breeze to process both channels with one set of controls, ensuring true stereo operation.
Highly requested since they released their flagship EQP-A Equalizer back in 2019, AudioScape is happy to finally make this stereo version a reality. If you love the EQP-A, but wished for a stereo solution, AudioScape’s EQP-2A is your wish come true.
PLEASE NOTE THAT THE EQP-2A IS DEEPER THAN THE EQP-A. THE EQP-2A IS 13.25” (34cm) DEEP.
**NOTE: EURO VOLTAGE UNIT (230-240V)

ICONIC AND IMMENSELY WEIGHTY, “ELECTRIC” EQUALIZATION
AudioScape EQP-2A: Legendary Tube Equalization in a New Stereo Format
AudioScape's newest addition to the lineup, the EQP-2A stereo tube EQ is an uncompromising, authentically USA-made recreation of a classic American vintage tube equalizer known for imparting a uniquely electric, silky sheen and thundering, tight low end to countless recordings over the last half-century. And in true AudioScape fashion, an extraordinary amount of time, passion and obsessive attention to detail was spent refining and perfecting their take on the legendary EQP circuit to ensure every EQP-2A behaves and performs just like the original - all at a peerless price point within reach of engineers working at any level.
Painstaking Circuit Design & Carefully Selected, Period-Correct Components
With a unit as famed and beloved as the EQP, it's no surprise that there are many clones on the market claiming to capture the magic and vintage soul of the original. But it turns out there's much more to this magic than meets the eye - literally. Just like the EQP-A, the EQP-2A includes: a full complement of NOS tubes, including the oft-excluded NOS 6x4 rectifier tubes (an important aspect of the original’s sound), custom-wound inductors, and high-end custom iron that matches the specifications and performance of the originals, including the critical inter-stage transformer omitted from most EQP clones despite its crucial contributions to both performance and the original’s box tone. By necessity, they've actually corrected the EQP circuit to more accurately reflect the behavior and sound of the vintage units, after finding the original schematics contained errors that drastically affected performance at certain filter settings. The difference is remarkable, and it reinforces their belief that no amount of research, development, listening tests, or time is too much to invest in a product of this pedigree.
Electrifying, Larger-Than-Life Sonic Elegance
The EQP-2A has been built from the ground up accurately and faithfully, with no component compromises and no gratuitous enhancements. They've invested an immense amount of time testing and refining this EQP-2A to produce the same awe-inspiring reaction engineers around the world have felt when using the original; every-time the circuit is engaged or a setting is changed. And they're confident you'll feel the same!
Our Philosophy - Recreating the Euphonic Sonics of a Bygone Era
Like every AudioScape product, the EQP-2A was designed and built with one core principle in mind: Sonic Truth! They're proud to offer you a unit that they feel truly replicates the magic, mojo, and character of such a classic, time-tested tube EQ. They can't wait to hear what you have to say and hope you love it as much as they are proud of it!
Handcrafted in the USA - Legendary Circuits deserve Legendary Craftsmanship
AudioScape builds and assembles each of their products by hand here at their workshop in Florida, using NOS and USA-made components wherever possible, and never compromising or making concessions to any aspect of the build or more importantly, the sonics for the sake of profit margins or simple convenience. They strongly believe this is the right way - if not the only way - to produce these units at the level of quality they strive for, while still making them available to as many of their customers as possible. Every product comes with a hassle-free two year warranty, and they pride themselves on providing the best customer service in the biz! If you have any questions, concerns, or just want to talk shop, please reach out to them!

IS THIS AN UPGRADE OR BETTER THAN A EQP-A?
NO! This is literally an EQP-A in stereo form. Aside from some minor cosmetic differences, it is exactly the same circuit, tube and component compliment (they get products right when they release them the first time). Additionally, there are some that may prefer the separate dual mono controls on the EQP-A as it provides more individual control. The EQP-2A is for those who have limited rack space, or prefer a simpler stereo equalizer in a 3U format.

Hoiatused ja ohutusteave
- Elektrilöögi oht – Ärge kunagi avage seadet, kui see on vooluvõrku ühendatud, kuna selle sees on kõrge – potentsiaalselt eluohtlik – võrgupinge. Jätke hooldustööd eranditult kvalifitseeritud spetsialistidele.
- Vesi ja niiskus – Ärge kasutage seadet veeallikate läheduses ega liigse niiskusega keskkonnas.
- Esemete ja vedelike sissetung – Tuleb jälgida, et korpuse avade kaudu ei kukuks sisse esemeid ega satuks vedelikke.
- Ventilatsioon – Seadme paigaldamisel püstikusse või muusse kohta veenduge, et on tagatud piisav ventilatsioon. Puudulik ventilatsioon põhjustab ülekuumenemist ja võib seadet kahjustada.
- Kuumus – Seade peaks asuma eemal soojusallikatest või muudest soojust tekitavatest seadmetest.
- Toiteallikad – Seadet tohib ühendada ainult kasutusjuhendis kirjeldatud või seadmele märgitud tüüpi toiteallikaga.
- Toitejuhtme kaitse – Vahelduvvoolu toitejuhtmed tuleks paigutada nii, et neile ei saaks peale astuda ning need ei jääks esemete alla või vastu surutuks. Pöörake erilist tähelepanu juhtmetele pistikute, pesade ja seadmest väljumise koha juures. Ärge kunagi puudutage pistikut ega juhet märgade kätega. Ühendamisel või lahtiühendamisel haarake alati pistiku korpusest.
- Mittekasutamise perioodid – Kui seadet pikemat aega ei kasutata, tuleks vahelduvvoolu toitejuhe pistikupesast välja tõmmata.
- Hooldust vajavad kahjustused – Sellistel puhkudel võtke ühendust kvalifitseeritud tehnikuga.
