Radial Engineering JDI Stereo is a passive stereo direct box designed to handle extreme signal levels without distortion of any kind. Unlike an active DI that is limited by the buffering amplifier's rail voltage, JDI Stereo employs a pair of Jensen audio transformers that at once balance the signal and lower the impedance to drive long cables. No power is required: you simply plug in and it works.
The magic comes from the amazing Jensen transformers inside. Jensens are legendary in their ability to gracefully handle transients while delivering a smooth, warm-sounding Bessel curve reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz with virtually zero phase deviation, JDI Stereo delivers the natural, pure sound of the instrument without artifact. In addition to converting the unbalanced Hi-Z signal to low, the transformers also serve to isolate the input from the output, essentially filtering out stray DC voltage that can cause noise and lead to so-called ground loops. This allows audio to pass while eliminating problems.
Features include input and thru-put 1/4" connectors plus a -15dB input pad on each channel. This is supplemented with a ground lift switch that lifts pin 1 on the two XLR outputs to further reduce hum and buzz caused by ground loops. Built tough to handle the abuse of live touring, JDI Stereo employs a 14-gauge steel I-beam inner frame and a unique 'book-end' outer shell. The innovative design eliminates stress on the PCB, reducing opportunity for solder joints to go 'cold' while the outer shell creates a protective zone around the switches and connectors. The steel enclosure works with the transformer's MuMETAL cans and internal Faraday shield to protect the sensitive inner workings from powerful magnetic fields such as those generated by stage amplifiers. This ensures the signal transfer is quiet and free from hum.

All warranty claims require a return authorization. Contact the Radial customer service department for details.
As with all typical warranties, only manufacturing defects are covered. Furthermore, parts that are subject to wear and tear such as switches, potentiometers and tubes are not covered under this warranty. This, however, does not mean that these will not be repaired or replaced free of charge. We pride ourselves in supporting the products we sell and will often exchange these parts free of charge pending the age of the device. This decision will be undertaken by RADIAL and in no way obliges the company to perform such tasks.
