It features an exceptionally high 140kΩ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal MuMETAL® shield to protect against electromagnetic fields that can cause unshielded transformers to distort.\u003c\/p\u003e\n\u003ctable class=\"table feature-product\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio circuit type:\u003c\/td\u003e\n\u003ctd\u003ePassive, transformer based\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransformer:\u003c\/td\u003e\n\u003ctd\u003eEclipse ET-DB2, 12:1 ratio\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of channels:\u003c\/td\u003e\n\u003ctd\u003eSingle channel (mono)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response:\u003c\/td\u003e\n\u003ctd\u003e20Hz ~ 18.5KHz (± 0.2dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDynamic range:\u003c\/td\u003e\n\u003ctd\u003e128dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal harmonic distortion:\u003c\/td\u003e\n\u003ctd\u003e0.01% from 20Hz~20kHz @-10dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Deviation:\u003c\/td\u003e\n\u003ctd\u003e1° @ 100Hz; 8° @ 20Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance:\u003c\/td\u003e\n\u003ctd\u003e140k Ohms, unbalanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance:\u003c\/td\u003e\n\u003ctd\u003e150 Ohms, balanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Input:\u003c\/td\u003e\n\u003ctd\u003e+18dB @ 20Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"2\"\u003eFeatures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003eInput pad, Ground lift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Connectors:\u003c\/td\u003e\n\u003ctd\u003e1\/4\" in \u0026amp; thru\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Connectors:\u003c\/td\u003e\n\u003ctd\u003eXLR-M out\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"3\"\u003eGeneral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction:\u003c\/td\u003e\n\u003ctd\u003e14 gauge steel chassis \u0026amp; outer shell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e4.25” x 2.75” x 1.75\" (108 x 70 x 44mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e1.2lb (0.54kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping size (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e6.5\" x 4\" x 3\" (165 x 76 x 102mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping weight:\u003c\/td\u003e\n\u003ctd\u003e1.35lb (0.61kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower:\u003c\/td\u003e\n\u003ctd\u003ePassive, no power required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConditions:\u003c\/td\u003e\n\u003ctd\u003eFor use in dry locations only between 5°C and 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty:\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\u003ca title=\"Radial Warranty\" href=\"https:\/\/www.radialeng.com\/product\/prodi\/legal.php#Warranty\" target=\"_blank\"\u003eRadial 3-year, transferable\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2026\/02\/ProDI-ProD2-Manual-WEB-02-2026.pdf\" target=\"_blank\" title=\"Radial Pro DI User Guide\" rel=\"noopener\"\u003eUser Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Radial","offers":[{"title":"Default Title","offer_id":47950455242970,"sku":"R800 1100","price":134.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/9585\/9277\/files\/prodi-34-right.jpg?v=1780513869","url":"https:\/\/www.rocketmusicshop.com\/products\/radial-prodi-mono-passive-direct-box","provider":"RocketMusic","version":"1.0","type":"link"}
