Telefunken TDP-1 Mono Passive Direct Box

It's time to experience the high-quality and innovative Telefunken TDP-1 Mono Passive Direct Box, a product that stands out in the realm of professional audio equipment. This mono unit is a new passive direct box design that combines premium quality components with a rugged, durable construction, ensuring a reliable DI that produces a rich, warm tone.

The TDP-1 is powered by an OEP/Carnhill transformer, crafted in the UK, and follows a simple yet effective "less is best" design approach. This Telefunken passive DI is designed to enhance the natural tone and feel of your instrument, providing superior vibe and character, unlike other direct boxes that may strip your instrument of its soul or character.

Avoiding the common design pitfalls of overemphasizing harmonic distortion or hyping too much low-end, the Telefunken passive DI delivers a balanced output that sets a new standard in reliability and performance for direct boxes.

At the heart of this innovative product is a custom-wound output transformer by OEP/Carnhill. The circuit board boasts gold-plated traces and is hand-assembled with through-hole components, offering more secure and reliable connections than typical surface mount circuitry. The frequency response of the circuit is impressively broad, ranging from 10 Hz to 70 kHz, with extremely low distortion and self-noise.

Each TDP-1 unit is manually tuned by hand to ensure the lowest distortion figure possible, while its high input impedance prevents the loading down of passive pickups. This meticulous attention to detail and high-quality component selection results in a direct box that delivers a harmonically rich low end and detailed, open high-end clarity.

The TDP-1's circuit is housed in an extremely durable extruded aluminum enclosure with recessed switches and connectors. This robust construction is virtually indestructible, designed to withstand the rigors of regular gigging. Each channel features two heavy-duty metal toggle switches to engage a -15 dB pad and ground lift, offering you the flexibility and control you need, whether on stage or in the studio.

In summary, the Telefunken TDP-1 Mono Passive Direct Box is a reliable, professional, and high-quality solution for converting unbalanced audio signals to balanced ones, making it an ideal choice for musicians and audio professionals alike.
