Telefunken TDA-2 Active Stereo DI
The Telefunken TDA-2 Active Stereo DI is a premium stereo direct box that combines high-fidelity active circuitry with vintage analog character for professional-grade performance in both studio and live environments. Designed to handle stereo instruments and dual mono sources with precision and warmth, the TDA-2 delivers exceptional detail, dynamic range, and reliability.
Built with dual Class A FET amplifier stages and outfitted with two custom-wound UK-made OEP/Carnhill transformers, the TDA-2 offers a musical and transparent signal path that adds subtle analog coloration while maintaining full clarity. This active design is ideal for use with passive instruments, stereo keyboards, DJ rigs, drum machines, synths, and acoustic-electric instruments — any setup that requires pristine stereo signal routing with analog warmth.
The TDA-2 operates on 48V phantom power and features separate channels for Left and Right inputs, parallel thru outputs for monitoring or amp passthrough, and balanced XLR outputs for direct connection to mixers, interfaces, or preamps. Each channel includes its own ground lift switch to eliminate unwanted hum or ground loop noise.
Encased in a rugged black powder-coated steel chassis, the TDA-2 is built to withstand the demands of touring, stage setups, and professional studio work. High-quality Neutrik connectors and precision internal components ensure long-term reliability, while the compact format makes it easy to integrate into pedalboards, racks, or portable rigs.
