It is in good condition noting a few small blemishes and comes supplied professionally packaged along with remote control unit, reprinted manual, Burndy \u0026amp; SNAIC interconnect cables, plus of course our standard three month warranty. Please note for operation this item requires a SuperCap power supply.\u003cbr\u003e\nNaim Say….\u003cbr\u003e\nLike many of our products, the NAC 252 stems from good stock: it descends directly from the NAC 52, still one of the finest preamplifiers ever made. Capable of exceptional clarity, its power supply components reside in a separate enclosure: the SuperCap power supply unit. This ensures optimum isolation from electromagnetic interference and provides each of the ten audio circuits with an independent, fully regulated supply voltage. Additionally, separate power supplies for the digital control and switching circuitry further isolate the audio circuitry from noise. It’s this attention to detail that makes the NAC 252 so special – that, and our determination to let nothing stand in the way of your musical enjoyment.\u003cbr\u003e\nMany designs were explored for the NAC 252 and a complete review of the circuit topology and components took place in accordance with the developments pioneered in preamplifiers such as the NAC52. Hundreds of hours were spent listening to various designs, ensuring that the harmony between music and technology was always maintained.\u003cbr\u003e\nTen independently regulated power supplies are fed from the matching SuperCap power supply. Totally separate regulated supplies for the digital control and switching ensure no noise is generated in the audio circuits.\u003cbr\u003e\nPlease note this item requires a SuperCap power supply\u003cbr\u003e\nFeatures:\u003cbr\u003e\nSupport for both DIN and RCA inputs to facilitate connection into a wider range of systems\u003cbr\u003e\nTotally separate regulated supplies for digital control and switching circuitry\u003cbr\u003e\nPrecision rotary potentiometers with precious metal wipers\u003cbr\u003e\nAV bypass mode for simple connection to an existing AV system\u003cbr\u003e\nPowered input for use with StageLine or SuperLine phono stages\u003cbr\u003e\nSpecifications:\u003cbr\u003e\nAudio Inputs:\u003cbr\u003e\nOther Inputs: AV input configurable for unity gain\u003cbr\u003e\nInput Impedance: 47kΩ\u003cbr\u003e\nAnalogue Input: 4 x DIN, 2 x DIN, RCA\u003cbr\u003e\nInput Sensitivity: 75mV\u003cbr\u003e\nAudio Outputs:\u003cbr\u003e\nLine Outputs Variable (level): 775mV\u003cbr\u003e\nLine Outputs Fixed (level): 75mV, 600Ω\u003cbr\u003e\nLoad Impedance: 10kΩ (min.)\u003cbr\u003e\nOutput Impedance: \u0026lt;50Ω\u003cbr\u003e\nAnalogue: 1 x variable, 3 x fixed (DIN)\u003cbr\u003e\nPower Outputs: Naim phono amplifier\u003cbr\u003e\nFinish: Case: Black powder coated; Front: Brushed and black anodised\u003cbr\u003e\nDimensions: 432 (W) x 314 (D) x 87 (H) mm\u003cbr\u003e\nWeight: 7.0 kg\u003c\/p\u003e","brand":"2ndhandhifi","offers":[{"title":"Default Title","offer_id":51536177201493,"sku":"209369","price":1995.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/1094\/5365\/files\/IMG_8860-scaled_dee94d95-8e35-4dc7-86fe-191e6c9d09c6.jpg?v=1758826572","url":"https:\/\/2ndhandhifi.co.uk\/products\/naim-nac-252-pre-amplifier-4","provider":"2ndhandhifi.co.uk","version":"1.0","type":"link"}
