{"product_id":"naim-nac-252-pre-amplifier","title":"Naim NAC 252 pre Amplifier","description":"The NAC 252 descends from the NAC 52 - still one of the finest pre-amplfiers ever manufactured. It brings both control and connectivity advances over the NAC 52, and a significantly enhanced construction, aesthetic and finish. Its performance, too, is enhanced with the benefit of a decade of R \u0026amp; D bringing yet more speed, detail, transparency and music.\u003cbr\u003e\u003cbr\u003eImproved earthing arrangements have resulted in an entirely new circuit topology, built upon a single very high quality, anti-resonance main audio circuit board. Anti-vibration, resonance-controlling feet compliment the ingeniously slotted and suspended main circuit board to protect the sensitive internal components from resonance and microphonic vibration. Ten independently regulated power supplies are fed from the matching Super-Cap power supply. Totally separate regulated supplies for the digital control and switching ensure no noise is generated in the audio circuits.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSix line-level inputs including two user-configurable versatile (DIN \/ phono) inputs.\u003cbr\u003eUser configurable unity-gain AV input.\u003cbr\u003ePowered input for use with Stageline or Prefix phono stage.\u003cbr\u003eFull infrared remote control.\u003cbr\u003eRC5 input for wired remote control in complex installations.\u003cbr\u003eOptional RS232 input \/ output for use in full home automation systems.\u003cbr\u003eThe Naim Super-Cap power supply provides each of the ten audio circuits with an independent regulated power supply.\u003cbr\u003eSeparately regulated power supply for the digital control and switching circuitry.\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":"Naim NAC 252 Pre Amplifier (Exc Supercap DR)","offer_id":57407186764108,"sku":"NAIMNAC252","price":5832.5,"currency_code":"GBP","in_stock":true},{"title":"Naim NAC 252 (Inc Supercap DR)","offer_id":57415881523532,"sku":"NAIMNAC252incsupercapdr","price":9873.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/naimnac252.jpg?v=1777455300","url":"https:\/\/www.stoneaudio.co.uk\/products\/naim-nac-252-pre-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
