{"product_id":"demo-nuprime-amg-pra","title":"NuPrime AMG PRA","description":"\u003cp\u003eNuPrime AMG PRA is the latest addition to the family and one of NuPrime’s finest preamplifiers. A minimalist, clean preamplifier without a built-in DAC, focusing on the careful handling of the music signal. We strongly recommend a pair of AMG STA power amplifiers to avoid holding back the reproduction; Evolution One is also an excellent partner for this preamplifier.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSomething new and unusual on the market is four-step tonal adjustment to match your taste and electronics.

A user-selectable 4 stage “Active Low Frequency and Harmonic Gain” control gave it distinctive characteristics to enhance the speaker performance, a world-first in preamp design.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv id=\"row-803984759\"\u003e\n\u003cdiv id=\"col-1774134096\"\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe AMG series front panel embodies its spirit. It is milled from a 15mm hardened aerospace aluminum alloy using a four-axis CNC machine with a diamond cutter through a 48-step process. Design elements such as the 3D “floating” logo, the curved surface around the front panel switch, and diamond-cut edge bring the quality of ultra-high-end audio products to the affordable range of the AMG series.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"row-1219247078\"\u003e\n\u003cdiv id=\"col-995110073\"\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe design goal for AMG PRA was to deliver a transparent-sounding analog preamp with its distinctive characteristics. Several new design concepts were developed and used in the AMG-PRE besides 1MΩ input impedance to achieve the best analog inputs.\u003c\/p\u003e\n\u003cp\u003eUsers of smallish speakers would often detect a distinct drop in bass response with some audio tracks. Instead of a simple “Bass Boost” function that lifts a targeted low-frequency band, a user-selectable 4-stage “Active Low Frequency and Harmonic Gain” control compensates for the lack of bass presence. It achieves some bass extension and a more natural roll-off.\u003c\/p\u003e\n\u003cp\u003eAdditional features such as the 2-stage gain control and invertible phase control increase the compatibility of the AMG-PRA with other power amplifiers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"row-2146941149\"\u003e\n\u003cdiv id=\"col-1989755334\"\u003e\n\u003cdiv\u003e\n\u003ch3\u003eTechnical Details\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"row-785466871\"\u003e\n\u003cdiv id=\"col-648935448\"\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe layout of the AMG-PRA takes excellent care in isolating the sensitive audio signals from the power circuitry. The power circuitry comprising a star-topology power and ground layer is built on one board, while a separate board houses the preamplification circuit. An isolation layer separates these two boards, further minimizing interference. The result is highly transparent sound that is natural and not over-etched.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"row-1266578089\"\u003e\n\u003cdiv id=\"col-186856138\"\u003e\n\u003cdiv\u003e\n\u003ch3\u003eFront Panel Settings\u003c\/h3\u003e\n\u003cp\u003eLeft Toggle Switch: Output Gain\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUpwards: High Gain\u003c\/li\u003e\n\u003cli\u003eDownwards: Low Gain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRight Toggle Switch: Output Phase\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUpwards: Phase Invert\u003c\/li\u003e\n\u003cli\u003eDownwards: Phase Normal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLeft knob: Loudness Compensation\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTurn the knob to switch between Loudness Compensation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRight Knob: Power, Input Selector, and Volume\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePress and hold for 3 sec to turn standby mode on\/off\u003c\/li\u003e\n\u003cli\u003eBriefly press to select the input\u003c\/li\u003e\n\u003cli\u003eTurn the knob to adjust the volume\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"row-1698585396\"\u003e\n\u003cdiv id=\"col-465065273\"\u003e\n\u003cdiv\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\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\u003eVolume level 92 is 0dB input = output\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\u003ch3 style=\"box-sizing: border-box; color: #555555; width: 771.5px; margin-top: 0px; margin-bottom: 0.5em; text-rendering: optimizespeed; font-size: 1.25em; font-family: 'PT Sans', sans-serif; font-weight: bold;\"\u003e\u003cbr\u003e\u003c\/h3\u003e","brand":"NuPrime","offers":[{"title":"Default Title","offer_id":54651837907282,"sku":null,"price":14900.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/9454\/6667\/products\/nuprime-amg-pra-forsteg-front.jpg?v=1702818141","url":"https:\/\/maxxteknik.com\/en\/products\/demo-nuprime-amg-pra","provider":"Maxxteknik","version":"1.0","type":"link"}
