A Naim design project group began reviewing the existing pre-amplifier designs exploring possibilities for major design improvement over the existing reference pre-amplifier, the Naim NAC 52.\u003cbr\u003e\u003cbr\u003ePower supply design has always been at the heart of Naim research and this project was no exception. For the NAC 552 a radical new split rail power supply configuration has been employed that almost eliminates power supply noise in the signal earth. Housed in a separate, full-width brushed aluminium case; the power supply features a massive 800 VA toroidal transformer, three enormous smoothing capacitors and fourteen hand selected power regulators to independently supply the different stages of the pre-amplifier.\u003cbr\u003e\u003cbr\u003eAs pioneered in the Naim CDS compact disc player fully suspended sub-chassis mounted circuit boards are used in the Naim NAC 552. This method of suspension maximises isolation, hence minimizing the effect of vibration on the highly sensitive electronic components.\u003cbr\u003e\u003cbr\u003eThe NAC 552 owner can configure two of the inputs for use with the more common RCA phono type connectors, enabling the use of alternative components with pre-owned interconnects. Each of the six inputs has separate listen and record facilities. A dedicated unity gain input is provided for use with the Naim AV2 processor or similar.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSpecifications\u003cbr\u003eAnalogue inputs 6 (configurable)\u003cbr\u003eTape outputs 3\u003cbr\u003eInput sensitivities 75mV, 47kOhm\u003cbr\u003eOutput levels, tape 75mV, 600 Ohm\u003cbr\u003eMain output 0.775V, \u0026lt; 50 Ohm\u003cbr\u003eOverload margin, all inputs, all audio frequencies 40dB\u003cbr\u003eDimensions (H x W x D) 87 x 432 x 314mm\u003cbr\u003eFinish Black, brushed aluminium","brand":"Naim Audio","offers":[{"title":"Default Title","offer_id":57407186895180,"sku":"NAIMNAC552","price":17582.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/naimnac552.jpg?v=1777455309","url":"https:\/\/www.stoneaudio.co.uk\/products\/naim-nac-552-pre-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
