Housed in a small, shielded metal chassis with a discrete industrial aesthetic, the Phono Box MM can be easily positioned adjacent to a turntable or integrated seamlessly into an existing Hi-Fi audio rack without taking up valuable space.\u003c\/p\u003e\n\n\u003cp\u003eEngineered around dual-mono internal circuitry and special low-noise ICs, the Phono Box MM delivers optimal channel separation while keeping total harmonic distortion under 0.04%. An external 18V DC power supply isolates sensitive internal amplification stages from AC mains noise, while gold-plated RCA input and output connectors ensure pristine signal transfer for budding vinyl enthusiasts.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; SYSTEM HIGHLIGHTS\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMM Cartridge Optimization:\u003c\/strong\u003e Specifically calibrated to provide 40 dB of gain and precise RIAA equalization for moving magnet (MM) cartridges.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eShielded Metal Chassis:\u003c\/strong\u003e Compact, heavy-duty metal enclosure protects sensitive internal electronics from electromagnetic and radio frequency interference.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDual-Mono Circuit Topology:\u003c\/strong\u003e Independent left and right channel architecture utilizes specialized low-noise ICs for superior channel separation and low noise floor.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eOutboard Power Supply:\u003c\/strong\u003e External 18V DC power adapter eliminates mains transformer hum and electrical interference from the audio signal path.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eGold-Plated RCA Connectivity:\u003c\/strong\u003e Features corrosion-resistant, gold-plated RCA input and output jacks for reliable signal transmission.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eUltra-Compact Footprint:\u003c\/strong\u003e Minimalist design allows placement directly next to a turntable for short, low-capacitance cable runs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\n\u003ctable style=\"width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Category\u003c\/td\u003e\n      \u003ctd\u003eMoving Magnet (MM) Phono Preamplifier\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBrand \/ Manufacturer\u003c\/td\u003e\n      \u003ctd\u003ePro-Ject Audio Systems\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel Designation\u003c\/td\u003e\n      \u003ctd\u003ePhono Box MM\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSupported Cartridge Type\u003c\/td\u003e\n      \u003ctd\u003eMoving Magnet (MM) Only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Impedance\u003c\/td\u003e\n      \u003ctd\u003e47 kΩ\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Capacitance\u003c\/td\u003e\n      \u003ctd\u003e120 pF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePreamplifier Gain\u003c\/td\u003e\n      \u003ctd\u003e40 dB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOutput Voltage\u003c\/td\u003e\n      \u003ctd\u003e500 mV @ 1 kHz (with 5 mV @ 1 kHz input)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal-to-Noise Ratio (Noise Floor)\u003c\/td\u003e\n      \u003ctd\u003e88 dB (A-Weighted)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTotal Harmonic Distortion (THD)\u003c\/td\u003e\n      \u003ctd\u003e\u0026lt; 0.04%\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRIAA Equalization Curve Accuracy\u003c\/td\u003e\n      \u003ctd\u003e20 Hz – 20 kHz \/ Max 0.5 dB deviation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAudio Inputs \/ Outputs\u003c\/td\u003e\n      \u003ctd\u003e1x Gold-Plated Stereo RCA Input Pair | 1x Gold-Plated Stereo RCA Output Pair\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExternal Power Supply\u003c\/td\u003e\n      \u003ctd\u003e18V \/ 500mA DC (Power Consumption: 20mA DC)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n      \u003ctd\u003e107 x 30 x 65 mm (107 x 30 x 75 mm including RCA sockets)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNet Weight\u003c\/td\u003e\n      \u003ctd\u003e280 g (0.62 lbs)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Pro-Ject","offers":[{"title":"Default Title","offer_id":53800752447754,"sku":"USED-E-938905","price":50.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/pro-ject-phono-box-mm-52353-p.jpg?v=1790179073","url":"https:\/\/audioemotion.co.uk\/products\/pro-ject-phono-box-mm","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
