It's the ideal integration of advanced design software, hardware, engineering know-how, and carefully controlled 'golden ears' tests. It has earned high marks for sonic performance since its introduction in 1988.\u003c\/p\u003e\r\n\u003cp\u003eThe basic circuit was originally published as an application note by Jensen for their finest microphone input transformer, the JT-16-B. Each channel uses two precision 990C operational amplifiers modules, developed and patented by Jensen, to achieve one tenth the distortion and twice the bandwidth of a single stage design.\u003c\/p\u003e\r\n\u003cp\u003eThe Jensen Twin Servo 990 has a 19\" wide mainframe rack-mount chassis (1.75\"H x 19\"W x 8\"D) and can be ordered with 1 to 4 channels. Additional channels can be easily added later up to the total capacity of the mainframe.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHighlights:\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eJT-16-B - input transformer\u003c\/li\u003e\r\n\u003cli\u003eTwo 990 discrete op-amps per channel - faster, quieter, more powerful and better sounding than typical monolithic op-amp\u003c\/li\u003e\r\n\u003cli\u003eElimination of all coupling capacitors from the signal path - results in less degradation of the audio signal\u003c\/li\u003e\r\n\u003cli\u003eJT-11-BMQ - output transformer\u003c\/li\u003e\r\n\u003cli\u003eInput bias current compensation circuitry and DC servo circuitry - eliminates signal degrading coupling capacitors\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"John Hardy Co.","offers":[{"title":"Default Title","offer_id":44449244053607,"sku":"5169","price":1625.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/john-hardy-co-jensen-twin-servo-990-mic-pre-single-chan_5169_1.jpg?v=1787088286","url":"https:\/\/vintageking.mom\/products\/john-hardy-co-jensen-twin-servo-990-mic-pre-single-chan","provider":"Vintage King","version":"1.0","type":"link"}
