Product Highlights

Useful in connecting a guitar, keyboard, bass—or indeed, any other instrument with a 1/4″ output—to an XLR input, the Telefunken TDA-1 is a single-channel DI box. The unit utilizes active, discrete class-A FET circuitry which, when coupled with components such as an OEP/Carnhill transformer, helps you to achieve a tone with clean, high headroom and a warm, saturated timbre. The TD-1 sports other constructive features which recommend it heartily; for instance, its printed circuit boards are assembled by hand with through-hole components; this ensures both security and reliability in its connection points. Additionally, all circuit traces have been gold-plated to bolster conductivity, while the circuit itself has been encased in an extruded aluminum enclosure. As such, you’ll find it more than suitable for the wear and tear of gigging.

Achieve pristine audio clarity and seamless signal integration with the Telefunken TDA-1 Mono Active Direct Box, designed to deliver a wide frequency range from 20 Hz to 50 kHz with minimal distortion. Featuring a custom-wound OEP/Carnhill transformer and low output impedance under 250 ohms, it ensures superior sound quality and compatibility with professional studio monitors. Discover how this compact, phantom-powered device can elevate your audio setup to the next level.
