The Telefunken TDA-1 (mono unit) is new active FET direct box designs that utilize top quality components in a modern take on classic circuitry to give you a full, rich character that both complements and retains the natural tone and feel of your instrument. The TDA circuit employs discrete Class-A FET circuitry coupled with a high quality transformer that provides the perfect balance between clean, high headroom performance and warm, saturated tone with vibe. 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 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 +/- 2dB from 20 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 circuit is powered from standard +48V phantom power with an LED indicating when it is powered. The TDA-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.
