RADIAL JDI DUPLEX MK4 STEREO DI DIRE - Part Number 000109
JDI Duplex Mk4 stereo direct box Stereo direct box for high-output digital sources Jensen transformers for warm Bessel curve Virtually zero distortion from 10Hz to 80kHz Stereo-to-mono merge (Y-mix) on each channel Built tough to handle the extremes The Radial JDI Duplex Mk4 is a full-featured passive DI designed to enhance connectivity for the touring professional and AV integrator. The Duplex comes equipped with 1/4" connectors for -10dB consumer electronics and XLR inputs for +4dB professional line sources. Each Duplex channel employs the same high-performance Jensen audio transformer as the industry standard Radial JDI direct box and has the same pristine audio signal path with virtually zero phase, harmonic and linear distortion. Natural transformer saturation and warm Bessel curve makes the Radial Duplex the perfect choice for rounding out highly dynamic instruments, like digital keyboards, that can sound harsh when driven hard. Transformer isolation also provides the benefit of eliminating troublesome ground loops that can cause hum and buzz and can interfere with video displays. Radial's innovative 'book-end'™ design provides protective zones that shield connectors and switches from the abuses of professional touring . A welded I-beam inner frame is designed to eliminate outside stresses that could torque the PC board and cause premature solder point and trace failure. A 14-gauge steel shell couples with the mu-metal transformer shield to eliminate stray magnetic field interference from power transformers and a full-bottom no-slip pad provides plenty of stay-put and helps reduce electrical coupling from amplifier chassis hardware. The Radial Duplex Mk4 is the worlds finest passive stereo direct box.
