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.

When used less aggressively, one can attenuate bands of frequencies above or below the “turnover” point to their desired levels.

The Qure On switch puts a coil\/condenser\/resistor filter network (LCR) into the tube output stage. This network is integrated into the coupling path of the tube and reacts on the dynamic response of the input signal by influencing THD spectra and phase response. The Qure potentiometer changes the frequency response and produces a fresh and silky top-end and a mid-range free of sharpness and harshness. For example, vocals can be \"placed\" in the front of a mix without having to provide more \"space\", also background or layer sounds can gain improved spatial depth.","brand":"SPL Audio","offers":[{"title":"Default Title","offer_id":44449455013991,"sku":"20933","price":1650.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_spl_qure_eq_db338761-7f89-40ce-85e6-c55a2b0e2096.jpg?v=1787089023"},{"product_id":"universal-audio-550-a-filter-used","title":"Universal Audio 550-A Filter (Vintage)","description":"\u003cp\u003eVery clean used example of this unit, with rack ears.

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":"manley-massive-passive-1633-used","title":"Manley Massive Passive #1633 (Used)","description":"\u003cp\u003eThe \u003cstrong\u003eManley Massive Passive\u003c\/strong\u003e is a two channel, four band equalizer, with additional high pass and low pass filters. \"Passive\" refers to the tone shaping part of this clever new EQ design, not using any active circuitry.
