The Radial Engineering JDI Stereo Passive Direct Box features Jensen transformers that balance your signal and minimize its impedance for driving lengthy cables. JDI Stereo gives you two passive channels for stereo or dual mono DI applications. This device features a flat frequency response from 10 Hz to 40 kHz, preserving the instrument’s original natural sound. Transformer-isolated inputs and outputs are included on each channel. Coupled with a -15 dB adjustable pad, this passive direct box cuts down on noise. Its interior Faraday shield further reduces interference. Due to its 14-gauge steel construction, the JDI Stereo is equally at home on stage as it is in the studio.
