Telefunken TDP-2 Dual-Channel Passive Direct Box

Useful in connecting a guitar, keyboard, bass—or indeed, any other instrument with a 1/4" output—to an XLR input, the Telefunken TDP-2 is a dual-channel DI box. It is passive in its construction, requiring no power whatsoever to run, though components such as an OEP/Carnhill transformer assist in lending the box tone both warm and rich.
