The power circuitry comprising of a star topology power and ground layers is built on one board while a separate board houses the pre-amplification circuit. An isolation layer separates these two boards, which further minimizes interference. The effect is a highly transparent sound that is natural and not over etched.\u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency Response: 10Hz to 200kHz; +-0 to -0.1dB\u003c\/li\u003e\n\u003cli\u003eTHD: 0.008 %\u003c\/li\u003e\n\u003cli\u003eInput Impedance:\n\u003cul\u003e\n\u003cli\u003eBalanced IN: 1M Ohm @ 10 Hz ~ 200 kHz\u003c\/li\u003e\n\u003cli\u003eLine IN: 1M Ohm @ 10 Hz ~ 200K Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eRated Output Voltage: 2 V (LINE) \/ 4V (BAL) @ 100 Ohm\u003c\/li\u003e\n\u003cli\u003eS\/N: 95 dB\u003c\/li\u003e\n\u003cli\u003eLoudness Compensation:\n\u003col\u003e\n\u003cli\u003e2.2 dB (125 Hz)\u003c\/li\u003e\n\u003cli\u003e4.5 dB (100 Hz)\u003c\/li\u003e\n\u003cli\u003e5.3 dB (75 Hz)\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/li\u003e\n\u003cli\u003eGain : 3.2 (High) \/ 2.1 (Low)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003col\u003e\u003c\/ol\u003e\n\u003col\u003e\u003c\/ol\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"NuPrime","offers":[{"title":"Black","offer_id":62737966170271,"sku":null,"price":2450.0,"currency_code":"CAD","in_stock":true},{"title":"Silver","offer_id":62737966203039,"sku":null,"price":2450.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/5532\/6111\/files\/AMG-PRE_right_1024x1024_98a4b615-2403-4749-a262-e2dad32243c8.jpg?v=1774471761","url":"https:\/\/altitudoaudio.ca\/products\/amg-pra-preamp","provider":"Altitudo Audio","version":"1.0","type":"link"}
