The Radial JDI-Duplex stands as a premium passive stereo direct box that combines exceptional connectivity with pristine sonic quality through its dual Jensen audio transformer design. This full-featured unit handles signals with virtually zero phase shift or harmonic distortion, whilst the natural saturation characteristics of Jensen transformers create a warm Bessel curve response that smooths out highly dynamic instruments including active bass guitars, digital pianos and electronic drums that can sound harsh under extreme conditions.
Comprehensive connectivity options include ¼" instrument inputs, RCA connectors, 3.5mm TRS for -10dB consumer electronics, plus XLR inputs accommodating +4dB professional line sources. The robust steel construction features Radial’s innovative book-end design that creates a protective zone around jacks and switches, working alongside the internal mu-metal shielding to guard against electromagnetic interference.
Transformer isolation provides the crucial benefit of eliminating troublesome ground loops that cause hum, buzz and interference with both audio systems and video displays. The Duplex combines outstanding connectivity with superlative audio quality and dependable performance for professional applications.
