The original 550A modules have become so sought-after that they were the logical inclusion for the open-access 500-Series format that API invented.\u003c\/p\u003e\n\n\u003cp\u003eA simple switchable three-band EQ, the API 550A has selectable shelving on the high and low bands with an independent band-pass filter. Proportional Q on the 550A allows smooth transition between the three frequency bands, gradually narrowing as more EQ is applied, up to 12dB.\u003c\/p\u003e\n\n\u003cp\u003eThe sound is unmistakably API - full of character and presence, with plenty of headroom and all the tonal sweetness that you need, to bring out the best in your instruments. Putting the API 550A into a Lunchbox, 500 Series gives you the power to use that fabled quality on the move.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAPI 550A Overview:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e3 bands of classic API equalization\u003c\/li\u003e\n\n\u003cli\u003eEach band offers 7 API selected frequency centres\u003c\/li\u003e\n\n\u003cli\u003eReciprocal and repeatable filtering\u003c\/li\u003e\n\n\u003cli\u003eMaximum 12 dB of boost\/cut per band\u003c\/li\u003e\n\n\u003cli\u003eEQ Band 1 and 3 offer shelf\/peak switching\u003c\/li\u003e\n\n\u003cli\u003e\"Proportional Q\" narrows filter Q at extremes\u003c\/li\u003e\n\n\u003cli\u003eTraditional API fully discrete circuit design\u003c\/li\u003e\n\n\u003cli\u003eHigh headroom +30 dB clip level\u003c\/li\u003e\n\n\u003c\/ul\u003e","brand":"KMR Audio","offers":[{"title":"Default Title","offer_id":57790130848127,"sku":null,"price":770.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/4915\/9716\/files\/api-550a-kmraudio.jpg?v=1716468360","url":"https:\/\/kmraudio.com\/products\/api-550a-b-stock-1","provider":"KMR Audio","version":"1.0","type":"link"}
