Telefunken TD-2 Passive Stereo DI
The Telefunken TD-2 Passive Stereo DI is a high-end stereo direct box engineered for professional audio applications where pristine signal integrity, analog warmth, and rugged reliability are essential. Designed for both live sound and studio environments, the TD-2 captures the full sonic detail of your instruments and stereo sources while offering exceptional headroom and ultra-low distortion.
Featuring two hand-wound UK-made OEP/Carnhill transformers, the TD-2 offers the same legendary analog character found in vintage studio gear. Each channel provides full galvanic isolation, eliminating unwanted hum, buzz, and ground loops while maintaining frequency accuracy and dynamic range. This makes the TD-2 perfect for keyboards, synths, drum machines, samplers, DJ equipment, stereo guitars, and more.
As a fully passive stereo unit, the TD-2 requires no batteries or phantom power. Its robust steel enclosure and road-ready design make it ideal for touring musicians, FOH engineers, and recording professionals alike. The dual-channel layout includes independent inputs, thru jacks for amp or monitoring connections, and balanced XLR outputs that interface easily with professional mixing consoles or recording interfaces.
Every detail of the TD-2 is tailored for tonal accuracy, build quality, and professional performance — from premium Neutrik connectors to the custom-wound transformers that shape its rich, musical sound. Whether you’re on stage or in the control room, the TD-2 is the ultimate stereo DI box for capturing the full character of your stereo signal path.
