By pairing discrete Class-A FET circuitry with a high quality, European-made transformer and a rugged metal enclosure, the TDA DI’s provide exemplary sound quality and reliable performance. The circuit boasts a frequency response of ± 2dB from 20 Hz to 70 kHz with extremely low distortion and self-noise, and each individual unit is manually tuned for the lowest possible distortion figure in TELEFUNKEN’s US facility. This careful attention to detail and high-quality component choices result in a harmonically rich low end and a detailed, open high-end. On the TDA-2, each channel features its own independent -15dB pad, ground lift, and +48V phantom power LED indicator. Every TDA unit is assembled, tuned and tested in Connecticut, USA.\u003c\/p\u003e\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"600\" height=\"600\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/12\/Telefunken-TDA-1-Mono-Active-Direct-Box.png\" alt=\"Telefunken TDA-1 Mono Active Direct Box\" title=\"Telefunken TDA-1 Mono Active Direct Box\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"600\" height=\"600\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/12\/Telefunken-TDA-1-Mono-Active-Direct-Box-2.png\" alt=\"Telefunken TDA-1 Mono Active Direct Box (2)\" title=\"Telefunken TDA-1 Mono Active Direct Box (2)\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\u003ch1\u003eFeatures\u003c\/h1\u003e\t\t\t\t\n\t\t• Custom-wound OEP\/Carnhill transformer, made in the UK• Phantom powered class-A discrete FET circuitry• Switchable -15 dB pad and ground lift• All metal construction• Recessed switches and connectors• 100% through-hole components• Assembled, tuned and tested in the USA\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"1024\" height=\"683\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/12\/Telefunken-TDA-1-Mono-Active-Direct-Box-7.jpg\" alt=\"Telefunken TDA-1 Mono Active Direct Box (7)\" title=\"Telefunken TDA-1 Mono Active Direct Box (7)\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"1024\" height=\"683\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/12\/Telefunken-TDA-1-Mono-Active-Direct-Box-6.jpg\" alt=\"Telefunken TDA-1 Mono Active Direct Box (6)\" title=\"Telefunken TDA-1 Mono Active Direct Box (6)\"\u003e\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\u003cimg width=\"1024\" height=\"683\" src=\"https:\/\/suhavimart.com\/wp-content\/uploads\/2025\/12\/Telefunken-TDA-1-Mono-Active-Direct-Box-5.jpg\" alt=\"Telefunken TDA-1 Mono Active Direct Box (5)\" title=\"Telefunken TDA-1 Mono Active Direct Box (5)\"\u003e","brand":"Sur Sargam","offers":[{"title":"Default Title","offer_id":52663905255721,"sku":null,"price":33890.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/0750\/9801\/files\/Telefunken-TDA-1-Mono-Active-Direct-Box-1.jpg?v=1770879039","url":"https:\/\/sursargam.com\/products\/telefunken-tda-1-mono-active-direct-box","provider":"Sur Sargam","version":"1.0","type":"link"}
