It features the latest circuit topology and carefully selected high-quality materials for lowest noise and extremely precise RIAA equalisation with minimum deviation. This brings out the sonic character of every phono cartridge, letting the listener fully enjoy the enchanting music qualities of analogue records.\u003c\/p\u003e\u003cp\u003eMC\/MM switching can be performed with the controls on the front panel of the amplifier. For MC, the impedance most suitable for the cartage in use can be selected (30\/100\/300 ohms). The board also incorporates a subsonic filter set to 25Hz at -12dB per octave, to cut ultra-low frequency noise and woofer flutter cause by record warps which could otherwise affect reproduction quality in the audible spectrum.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"http:\/\/www.accuphase.com\/cat\/option_board.pdf\"\u003eOption board compatibility chart.\u003c\/a\u003e\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ch4\u003eMC : Moving Coil type\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e 66 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 30\/100\/300 ohms (selectable)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 0.126mV\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFrequency Response (20Hz～20kHz):\u003c\/strong\u003e ±0.3dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eS\/N Ratio:\u003c\/strong\u003e 84dB\u003c\/p\u003e\u003ch4\u003eMM : Moving Magnet type\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e 40 dB Input\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImpedance:\u003c\/strong\u003e 47 kilohms\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 2.5mV\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFrequency Response (20Hz～20kHz):\u003c\/strong\u003e ±0.3dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eS\/N Ratio:\u003c\/strong\u003e 86dB\u003c\/p\u003e","brand":"Accuphase","offers":[{"title":"Default Title","offer_id":13794175352941,"sku":"ACCAD50","price":1600.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0225\/9777\/products\/ad-50_1.jpg?v=1586310649","url":"https:\/\/soundline.co.nz\/en-int\/products\/accuphase-ad-50-phono-stage-board","provider":"Soundline Audio Online NZ","version":"1.0","type":"link"}
