Designed by the now legendary Saul Walker, an adjunct instructor in  music technology, the 550A has been used in recording studios throughout  the world, among them the Record Plant and Sunset Sound, and by such  musical greats as Jimmy Page, Phil Ramone, the Doobie Brothers, Stevie  Wonder, Leon Russell, Frank Zappa, Marvin Gaye, Herbie Hancock, and Bob  Dylan. In 2008 the API 550A was inducted into the Technology Hall of  Fame at the annual Audio Engineering Society (AES) Convention held in  San Francisco.\u003cbr\u003e\u003cbr\u003eWalker, a fellow of AES, designed the equalizer in  1968, and the discrete 550A was first used as a modular OEM equalizer.  As the industry rapidly embraced the sonic quality of the 550A, it  quickly found its way into many custom console designs by Frank DeMedio  and other leading engineers. Many of these consoles are still in use  today. \u003cbr\u003e\u003cbr\u003eForty years later, the 550A remains the standard against  which other EQs are measured, and it has played a major role in the  recording industry for decades. Still copied but never duplicated, the  550A became API's standard channel module EQ when the company began  manufacturing consoles in 1971. With virtually all existing units spoken  for, popular demand for this EQ resulted in API finally resuming  production in 2004. \u003cbr\u003e\u003cbr\u003eWhat accounts for its popularity and  longevity?  \"The 550A design provides a fast, repeatable, and virtually  foolproof mechanism to enhance or accentuate specific segments of the  audio spectrum or to de-emphasize other tonalities while maintaining the  essential integrity of the program material,\" Walker says. He notes  that though newer technology provides greater flexibility at lower cost,  permitting more drastic alteration of the sound spectrum, many artists  just prefer the sound of the original 550A.\u003cbr\u003e\u003cbr\u003eUsers of Walker's  equalizer are fond of its acoustic properties – the 'sweet tonal change'  coursing through the mix and its settings that allow for 'more bite or  body' in the basses. \"An equalizer is, in a way, a musical instrument,\"  Walker says.\u003cbr\u003e\u003cbr\u003eThe 550A provides reciprocal equalization at 15  points in 5 steps of boost to a maximum of 12dB of gain at each point.  The fifteen equalization points are divided into three overlapping  ranges. The high and low frequency ranges are individually selectable as  either peaking or shelving, and a band-pass filter may be inserted  independently of all other selected equalization settings. Frequency  ranges and boost\/cut are selected by three dual-concentric switches and a  push-button \"in\" switch allows the EQ to be silently inserted into the  signal path. A small toggle switch is used to engage the band-pass  filter.\u003cbr\u003e\u003cbr\u003eThe combination of Walker's incomparable 2520 op-amp, and  his \"Proportional Q\" circuitry gives the 550A user an uncomplicated way  to generate acoustically superior equalization. \u003cbr\u003e\u003cbr\u003eThis  long-awaited, limited edition reissue is a continuation of the  equalizers produced by API exactly as they were in the 1960's, featuring  hand-wired switches, the original circuit board design and API founder  Saul Walker's signature on the chassis. an EQ that has had such a part  in the history of recording is continuing to make history in today's  music. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449404813415,"sku":"17100","price":1195.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/vintage_api_550a_sw_eq-saul_walker_edition_7ff1f816-e0d7-4030-92e1-e8576635895c.jpg?v=1787088874"},{"product_id":"a-designs-audio-em-peq-500-series-eq-used","title":"A-Designs Audio EM-PEQ 500 Series EQ (Used)","description":"Beautiful used 500 Series EQ module that sonically nods to the classic Pultec EQP-1A sound.\u003cbr\u003e\u003cbr\u003e","brand":"A Designs","offers":[{"title":"Default Title","offer_id":44449447182439,"sku":"11902","price":850.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_a_designs_audio_em-peq_500_series_eq_07731d09-7d7f-496c-83fa-bb432450eb58.jpg?v=1787088989"},{"product_id":"api-550a-1-eq-used","title":"API 550 A-1 EQ (Vintage)","description":"\u003cp\u003eClean used example of this unit.

One way I  can usually identify an A-1, without looking inside, is the rubbery  feel of the rotary switches instead of the snap you feel with a 550A.  550A-1's were sometimes found on ebay and sold as 550A's by sellers who  may or may not have known what it was because often the serial number  sticker said \"550A\" without a mention of A-1, and sometimes there was no  serial number sticker.\u003cbr\u003e\u003cbr\u003eLooking at the inside, there is one 2520  driving the output transformer with a feed-forward design using a NPN  transistor.

Overall, it was a good  design with good noise performance and had the same headroom as any  550A due to the 2520 and output transformer in the output stage. It is  not exactly a 550A with the Q difference and not quite as full in the  low end, in my own tests, but still better than other eq designs of its  time, as the popularity of using IC throughout in the late 70s became  prevalent and overall quality diminished.\u003c\/p\u003e","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449447215207,"sku":"4959","price":795.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_api_550a-1_eq_f347ff82-33e7-4cb3-bb03-8e4fdc82dd1c.jpg?v=1787088989"},{"product_id":"api-550a-eq-used","title":"API 550A EQ (Vintage)","description":"\u003cp\u003eVintage selectable-frequency 3 band EQ, with overlapping frequencies and hi\/lo pass filters.

Incorporating API's exclusive circuitry and proprietary components (such as the legendary API 2520 Op Amp), the 550b artfully blends the past with the present. So many hit records still depend on the unique 550 sound that engineers around the world find it to be an invaluable tool. In fact, the 550b design has been taken from the original blue prints and spec control drawings from the API archives. It is unlike any other EQ you will ever use.\u003cbr\u003e\u003cbr\u003eRather than offer a huge assortment of complex features, the API 550b provides exactly the right number of controls. Its four EQ bands are overlapped significantly to aid in dual roles as problem solver and sweetening device with each band offering seven switchable filter frequencies that span four-to-five octaves. These frequencies, purposely selected to be musical rather than numeric, were selected by an experienced \"who's who\" list of the industry's most proficient engineers.\u003cbr\u003e\u003cbr\u003eMaking use of API's \"Proportional Q,\" an innovation designed by Saul Walker in the '60s, the 550b intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings without the need for additional bandwidth controls. This unique feature minimizes the \"phase-shift\" sound found in many equalizers. In addition, the reciprocal nature of the 550b enables the user to \"undo\" what has been done previously with exact precision.\u003cbr\u003e\u003cbr\u003eThe benefits of the API 550b are most obvious to those who work with EQ on a continuous basis. If major tonal restructuring is required, the extraordinary headroom made possible with API's 2520 Op Amp offers the predictable and warm analog performance, even under duress. With a surprisingly wide range of tonal variations, the 550b is an invaluable and professional audio tool with great flexibility and excellent sonic ability. \r\n\r\n\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449447313511,"sku":"4939","price":795.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_api_550b_eq_stock_cat.jpg?v=1787088990"},{"product_id":"chandler-little-devil-equalizer-used","title":"Chandler Limited Little Devil Equalizer (Used)","description":"\u003cp\u003eNote: This unit is not VPR compliant and may not work with every 500 Series rack\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFollowing in the rich tradition of English 60s and 70s console design, Chandler Limited enters the 500 race furiously with its new \u003cstrong\u003eLittle Devil Equalizers and Compressors\u003c\/strong\u003e.

The Optograph's front end is balanced by an original Jensen input transformer. The output utilizes our specially recreated Nickel transformer. The essence of the compressor's character comes from our custom electroluminescent cell and discrete op-amp combination. The high quality circuit is pristine enough for bus compression, and yet has a unique character reminiscent of an antique world class compressor, that has just now been discovered.

Third, nothing below two-fifty. The fourth position is a musical bandpass filter. In this position, compression is triggered by the program's mid-range frequency content, ignoring the highest and lowest frequencies. The filters are amazingly useful for shifting the focus of what should be more compressed and creating compression curves on purpose. \u003cbr\u003e\u003cbr\u003eAnother unique feature for sculpting the overall sonic character is the Transformer Desaturate mode.

Incorporating API's exclusive circuitry and proprietary components (such as the legendary API 2520 Op Amp), the 550b artfully blends the past with the present. So many hit records still depend on the unique 550 sound that engineers around the world find it to be an invaluable tool. In fact, the 550b design has been taken from the original blue prints and spec control drawings from the API archives. It is unlike any other EQ you will ever use.\u003cbr\u003e\u003cbr\u003eRather than offer a huge assortment of complex features, the API 550b provides exactly the right number of controls. Its four EQ bands are overlapped significantly to aid in dual roles as problem solver and sweetening device with each band offering seven switchable filter frequencies that span four-to-five octaves. These frequencies, purposely selected to be musical rather than numeric, were selected by an experienced \"who's who\" list of the industry's most proficient engineers.\u003cbr\u003e\u003cbr\u003eMaking use of API's \"Proportional Q,\" an innovation designed by Saul Walker in the '60s, the 550b intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings without the need for additional bandwidth controls. This unique feature minimizes the \"phase-shift\" sound found in many equalizers. In addition, the reciprocal nature of the 550b enables the user to \"undo\" what has been done previously with exact precision.\u003cbr\u003e\u003cbr\u003eThe benefits of the API 550b are most obvious to those who work with EQ on a continuous basis. If major tonal restructuring is required, the extraordinary headroom made possible with API's 2520 Op Amp offers the predictable and warm analog performance, even under duress. With a surprisingly wide range of tonal variations, the 550b is an invaluable and professional audio tool with great flexibility and excellent sonic ability. \r\n\r\n\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449474609255,"sku":"10028","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_api-550b_eq_pair_horizontal_style_3c7116fd-1373-4045-bb94-303cac4a4192.jpg?v=1787089094"},{"product_id":"lachapell-audio-583s-used","title":"LaChapell Audio 583s (used)","description":"The \u003cb\u003eLaChapell Audio Model 583s\u003c\/b\u003e is the world’s first vacuum tube preamplifier designed for the 500 series format. Based on our popular 992EG, the 583s is quickly becoming the next must-have preamp for those looking to add that extra warmth and character to their “lunch box” collection found only within the thermionic realm. Our initial design approach was simple; identify and extract the key design elements of the 992EG that directly contributes to its’ sound signature, and then inject that into the 583s. This, of course, is the amplifier’s input stage, where the lion share of your signal’s quality and character is generated. While the 583s utilizes a more traditional single-ended amplifier configuration, the overall topology of the 583s’ microphone input stage is equal to that of the 992EG; specifically, feedback loop configuration, input transformer turns ratio, input impedance, capacitance, etc... Together with the CineMag CMOQ nickel alloy output transformer, the 583s also features an ultra clean output stage using premium Burr-Brown \u0026amp; THAT Corporation balanced line drivers. \u003cbr\u003e\u003cbr\u003eThe 583s comes with a few additional options. The standard microphone input transformer is the CineMag CMMI-10. However, users can specify the Jensen JT-115k (the very same used on the 992EG).

With the exception of the tube access opening, the 583s has an enclosed chassis, which helps direct cooling and prevents any unwanted interference. In operation, the user has individual control over the input and output gain stages via fully variable potentiometers. This, like its’ 992 older brother, provides total flexibility to explore the 583s’ broad sonic pallet, enhancing its versatility for your recording environment. Additional functions include four illuminated NKK toggle switches for 48v (Phantom), db input pad, polarity reverse and input select. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatured Highlights:\u003c\/b\u003e \u003cul\u003e \u003cli\u003eTrue Vacuum Tube Amplifier \u003c\/li\u003e\n\u003cli\u003eFully Variable Input~Output Control \u003c\/li\u003e\n\u003cli\u003eRobust Construction \u003c\/li\u003e\n\u003cli\u003eTransformer-less Hi-Z Input \u003c\/li\u003e\n\u003cli\u003ePremium Components \u003c\/li\u003e\n\u003cli\u003e80% Nickel Output Transformer \u003c\/li\u003e\n\u003cli\u003eClean, Attractive Layout \u003c\/li\u003e\n\u003c\/ul\u003e\u003ca href=\"http:\/\/www.proaudioreview.com\/article\/19962\" target=\"blank\"\u003eCheck out this review!\u003c\/a\u003e","brand":"LaChapell Audio","offers":[{"title":"Default Title","offer_id":44449474642023,"sku":"29344","price":715.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_29344_1_33b39117-6b99-48e4-9c23-6bf5e34fb021.jpg?v=1787089095"},{"product_id":"api-500-4b-lunchbox-used","title":"API 500-4B Lunchbox (Used)","description":"4 slot lunchbox for 500 series modules with built in PSU.","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449474674791,"sku":"29357","price":325.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_api_500-4b_lunchbox_6170e782-a270-4077-bccb-dfc2354f756a.jpg?v=1787089095"},{"product_id":"a-designs-audio-em-silver-used","title":"A-Designs Audio EM-Silver (Used)","description":"\u003cp\u003eThe \u003cstrong\u003eA Designs “EM Series\u003c\/strong\u003e” is a twist on the P-1.

It's authentic Retro compression for the masses. The Doublewide delivers the tube compression sound you expect because it is exactly that. While not precisely like any other tube compressor, the Doublewide methodology takes after the Sta-Level. As such, it excels at processing delicate sources like bass and vocals. It's all Retro and is built with the same quality components in our U.S. shop alongside our other products. \u003cbr\u003e\u003cbr\u003e The tubes and transformers in a fully complementary push-pull topology deliver sonic characteristics typical of a full sized tube compressor. The Doublewide incorporates four NOS 6BJ6 pentodes in two tube gain stages as well as two high-quality Cinemag transformers.  Input and output are fully floating and transformer balanced for use with line level signals. A hard-wire bypass switch allows for quick evaluation of the compression signature.  Compression attack and recovery times are continuously variable.  Like the Sta-Level and 176, the Doublewide has two timing characteristic modes; Single and Double.  Double mode provides a dynamic program-controlled attack and recovery timing. With these two modes, the Doublewide is versatile in the studio, with full control of weight and punch versus transparency.\u003cbr\u003e  \u003cbr\u003e The Doublewide is designed to provide the user with years of reliable service. Special circuitry eliminates excess current inrush and component stress when power is applied. Power required is 180 mA (6 watts), which is well within a two-slot power allowance. The stainless steel chassis provides good ventilation to minimize heat build-up. The tubes are self-biased and balanced without the need for user adjustments and there are no internal controls. A meter-zero adjustment is accessible from the side of the unit to compensate for tube variations.
