Amazing tape-like pure analog tonality, and a feature set that will blow your mind. Enter Crucial Audio’s world famous analog delay (BBD) circuitry driven by transformer-coupled Class A vacuum tube preamp stages. Prime Number and Tempo Indicators and an analog VU meter guide you towards the ultimate echoes and sonic excellence for your mix! Hand-built to order by Crucial Audio.\u003c\/p\u003e\r\n\u003ch3 id=\"toc_0\"\u003ePrime Numbers and Delay Times\u003c\/h3\u003e\r\n\u003cp\u003eLegendary producer and recording industry icon Rob Fraboni was a huge part of the inspiration to develop the Studio-Nugget’s Prime Number Identification algorithm. Professional producers and recording engineers have known that delay times\/echoes set to prime numbers deliver a sonic difference in overall echo clarity and level in the mix. It can be an effective technique at any song tempo.\u003c\/p\u003e\r\n\u003cp\u003eA prime number can only be divided by 1 and itself. Thus less likely to create phase cancellation of the fundamental frequencies during audible intermodulation events. One example is a multi-tone of 250 Hz + 1 kHz Dry and Delayed Sine Waves (summed with delay range of 80 – 120ms) @0 dBv and -10 dBv. Measurements on the Stanford Research Systems SR-760 FFT spectrum analyzer illustrate that a change of 1ms from a prime number can yield as much as -8 dBv in delay gain at the 1 kHz carrier during the 250 Hz intermodulation. Hence the audible difference of reported echo clarity and level within the frequency feast of the mix.\u003c\/p\u003e","brand":"Crucial","offers":[{"title":"Default Title","offer_id":44450733391975,"sku":"160086","price":2399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/crucial-studio-nugget_160086_1.jpg?v=1787094298","url":"https:\/\/vintageking.mom\/products\/crucial-audio-studio-nugget-rackmount-vacuum-tube-prime-number-analog-delay","provider":"Vintage King","version":"1.0","type":"link"}
