Telefunken TDP-2 Dual-Channel Passive Direct Box

A High-Quality Passive Stereo DI for Stage and Studio Use
The Telefunken TDP-2 is a dual-channel passive direct box designed to connect guitars, keyboards, basses, and other 1/4" output instruments to XLR inputs. With a passive circuit requiring no external power, the TDP-2 provides warm, rich tone thanks to its high-quality OEP/Carnhill transformers. Built for professional musicians and engineers, this DI box ensures reliable performance whether on stage or in the studio.

Premium Components for Exceptional Signal Clarity
At the core of the TDP-2 are UK-made OEP/Carnhill transformers, known for their ability to enhance signal integrity while adding warmth and musicality to any instrument. The signal path is constructed with gold-plated circuit traces and 100% through-hole components, ensuring superior conductivity and durability. This meticulous design guarantees clear and transparent sound reproduction with minimal signal loss.

Dual-Channel Design for Maximum Flexibility
With two independent channels, the TDP-2 allows users to connect and process two instruments simultaneously. Each channel features a dedicated -15 dB pad switch, ensuring compatibility with high-output instruments. A ground lift switch is also included for eliminating hum and unwanted noise, making it a valuable tool for both live sound reinforcement and recording applications.

Rugged Construction for Reliable Performance
Built to withstand the demands of touring and professional use, the TDP-2 is housed in a durable extruded aluminum chassis. Recessed switches and connectors provide additional protection, preventing accidental adjustments and ensuring longevity. Whether used in a studio rack or thrown into a gig bag for live performances, this DI box is designed to endure years of use without compromise.

Versatile Pass-Through Outputs for Recording and Live Sound
Each channel of the TDP-2 is equipped with a 1/4" pass-through output, allowing musicians to route their signal to an amplifier while simultaneously sending a clean DI signal to a mixer or recording interface. This feature is especially useful for reamping, capturing both a direct and amplified signal for greater flexibility in mixing and production.

Hand-Assembled for Professional-Grade Quality
Every TDP-2 unit is hand-assembled with precision, using only premium components such as Amphenol connectors, WIMA and Nichicon capacitors, and 1% 1/4W metal film resistors. These components contribute to the TDP-2’s reliability and consistent performance, ensuring it meets the highest standards for professional audio equipment.

A Must-Have Direct Box for Musicians and Engineers
With its passive design, high-quality transformers, and robust construction, the Telefunken TDP-2 is an essential tool for musicians, live sound engineers, and recording professionals. Whether used for direct recording, live performances, or signal routing in the studio, this DI box delivers clean, warm, and professional-grade audio with every use.
