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 Radial JDI 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.
The main features of the Radial JDI Duplex are:
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
