The Telefunken Elektroakustik TDP-2 Passive Stereo Direct Box combines premium quality components with a rugged construction to create a reliable DI with rich, warm tone. By utilizing an OEP/Carnhill transformer made in the UK, the TDP-2's less is best approach provides a superior character that best complements the natural tone of your instrument.
The Telefunken Elektroakustik TDP-2 Passive Stereo Direct Box is the go-to reliable, high quality direct box. The simple and elegant design approach yields a harmonically rich low-end with a detailed high end, delivering a new standard in reliability and performance for direct boxes.
Sonic Characteristic
While some direct boxes focus on providing sterile, ultra-clean gain, they often leave the instrument devoid of any soul or character. Conversely, some DI’s artificially hype too much low-end and overemphasize harmonic distortion, resulting in a tubby and undefined output. The Telefunken Elektroakustik active DI avoids these common design pitfalls and delivers a new standard in reliability and performance for direct boxes.
Circuit Design
The heart of the design is a custom-wound output transformer by OEP/Carnhill, made in the UK. The circuit board features gold plated traces and is entirely hand-assembled with through-hole components, providing more secure and reliable connections than typical surface mount circuitry. The frequency response of the circuit is ± 1dB from 10 Hz to 70 kHz, with extremely low distortion and self-noise. Each individual unit is manually tuned by hand for the lowest distortion figure possible. High input impedance prevents the loading down of passive pickups. This careful attention to detail and high quality component choices results in a direct box with a harmonically rich low end and a detailed, open high-end clarity.
Construction
The circuit is housed in an extremely durable extruded aluminum enclosure with recessed switches and connectors. This rugged construction is virtually indestructible, able to easily withstand the wear and tear of gigging. Each channel features two heavy duty metal toggle switches to engage a -15 dB pad and ground lift. The Telefunken Elektroakustik TDP-2 unit features two independent DI channels with separate controls, giving you the ability to run two instruments through one footprint on stage or in the studio.

Great DI
Oct 23rd 2017We record a lot of synths through DIs and preamps. Our studio has all the usual suspects; Radial, REDDI, RNDI, etc. The Telefunken two channel DI is a new addition I thought we would try...the cinemag transformers have a wonderful full sound and I’m very happy with it. Build quality is impressive and exceptional. Front End shipped quickly and I had it in hand within a couple of days of ordering... thank you!
