{"product_id":"i2audio-phono-one-mm-pre-amplifier","title":"i2Audio Phono One MM Pre-Amplifier","description":"\u003cp\u003eThe Phono One from i2Audio is a high-quality phono pre-amplifier for MM systems. It requires an external 12V power supply (we have a universal 12V 2A power supply here we use for the Arduino)\u003c\/p\u003e \u003cp\u003ei2Audio’s PhonoOne is a small, yet excellent sounding phono preamplifier for MM pick-ups. The design achieves a very low group delay distortion which results in a very natural replay of any kind of music.\u003c\/p\u003e \u003cp\u003eWith its input impedance of 47kΩ\/100pF and a fixed gain of 40dB, it suits a wide variety of MM systems. Highly linear SMD foil capacitors and high performance integrated operational amplifiers guarantee low noise and distortion.\u003c\/p\u003e \u003cp\u003eOnly a 12V DC power supply with minimum 100mA current capability is required. The onboard power management generates a symmetrical, low noise supply with ±8.5V for the amplifier stages which is key for a well-sounding preamplifier.\u003c\/p\u003e \u003ch2\u003eSpecifications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eInput impedance 47kΩ, 100pF\u003c\/li\u003e \u003cli\u003eTHD \u0026lt; 0,005% @ 1kHz\u003c\/li\u003e \u003cli\u003eS\/N \u0026gt; 78dB (a-weighted)\u003c\/li\u003e \u003cli\u003eGain 40dB @ 1kHz\u003c\/li\u003e \u003cli\u003eOutput voltage 500mV @ 5mV input, 1kHz\u003c\/li\u003e \u003cli\u003eRIAA deviation \u0026lt;0.5dB, 20Hz…20kHz\u003c\/li\u003e \u003cli\u003eSize 92 x 45mm2, height 14mm\u003c\/li\u003e \u003cli\u003eInput and output connections via gold-plated RCA connectors\u003c\/li\u003e \u003cli\u003eAdditional solder pads for input, output and supply\u003c\/li\u003e \u003cli\u003eSingle 12V supply, 5mm barrel jack\u003c\/li\u003e \u003cli\u003eTypical supply current ~50mA\u003c\/li\u003e \u003c\/ul\u003e","brand":"i2Audio","offers":[{"title":"Default Title","offer_id":46039336681532,"sku":"nro1787258016872","price":34.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/6985\/2220\/files\/i2audio-phono-one-mm-pre-amplifier_1.jpg?v=1787258025","url":"https:\/\/www.mossheath.com\/products\/i2audio-phono-one-mm-pre-amplifier","provider":"My Store","version":"1.0","type":"link"}
