Giving you 2 passive channels for stereo or dual mono DI applications, the JDI Stereo Passive Direct Box from Radial Engineering features Jensen transformers that balance your signal and lower its impedance for driving long cables. The unit boasts a flat frequency response from 10 Hz to 40 kHz, allowing the natural sound of your instrument to be unchanged. Each channel has a -15 dB selectable pad, along with transformer-isolated inputs and outputs, to help reduce noise. Interference is further reduced thanks to its internal Faraday shield. The JDI Stereo's 14-gauge steel construction allows the box to be just as suited for the stage as the studio.
