It is authentic in every detail and reproduces the exact sonic qualities of the original product.\u003c\/p\u003e  \u003cp\u003eUsing the original discrete analogue circuit design employing a feedback FET technique and maintaining the use of the same components that give this product such a distinctive sound, the new F765 compressor\/limiter will add dynamic punch to your sound as well as controlling peak excursions.\u003c\/p\u003e  \u003cp\u003eThe original F760-N module was used by major recording artists worldwide throughout the 60s, 70s, and 80s.

It is amazing that all that functionality and power is contained within the confines of a single slot 500 module and still have room for a GR meter! I'm sure if it were a two-space module it could also have the original's Gate\/Expander with all its controls and features too.\u003cbr\u003e\u003cbr\u003eNone-the-less, the F765 as is has the sound and color of the original 2U Compex processor. The F765 succeeds well as an excellent compressor\/limiter for any source from raucous vocals to boring drum recordings. It is a well-made quality piece of gear that, after initial setup, is easy to get solid operation.\u003cbr\u003e\u003cbr\u003eI just love my pair here in the rack and I use them on every mix.\"\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eBarry Rudolph\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eRead the full review \u003ca title=\"Barry Rudolph Field Test\" href=\"http:\/\/www.barryrudolph.com\/newtoys\/toys17\/q2_f765.html\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003ehere\u003c\/span\u003e\u003c\/a\u003e.\u003c\/p\u003e","brand":"Q2 Audio","offers":[{"title":"Default Title","offer_id":44449955479655,"sku":"59925","price":1249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/q2-compex-500_59925_1_22aaf762-1c4d-41ae-89e4-bb10050e809d.jpg?v=1787091093","url":"https:\/\/vintageking.com\/products\/q2-audio-compex-f765-500","provider":"Vintage King","version":"1.0","type":"link"}
