Radial Engineering is a manufacturer and distributor of professional audio equipment, building tools for the working audio and audio-video professional. Radial is located on the Fraser River, just outside Vancouver, British Columbia in the municipality of Port Coquitlam. The company began operations in the fall of 1991 as the Canadian distributor of Mogami cable and Jensen Audio Transformers. In 1992, it became a limited corporation under the JP Cabletek Electronics Ltd. banner. The Radial name was first used on house branded cables and snake systems. The Radial name and logo represents a cross section of quad cable; Radial being round. In 1996 the Radial JDI direct box was launched. This led the way to the Radial JDV and today, over 50 electronic products are now being produced under the Radial, Tonebone and Forest Audio brands. In 2001, the Primacoustic brand was launched to address the growing demand for acoustic products for the burgeoning home recording market and in 2006, the company officially changed its name to Radial Engineering Ltd.
Radial JDI Duplex is a high performance dual-channel direct box that is designed to provide maximum flexibility for the audio engineer in the most demanding applications. It features two custom-made nickel laminated transformers for optimal signal transfer with absolute minimal distortion of all types. Analysis reveals an exceptionally linear response from 10Hz to 40kHz with virtually zero phase shift at all critical frequencies. The excellent performance is further substantiated with a Fourier transform that produces desirable even order harmonic generation and a warm Bessel curve when pushed hard. With its heavy-duty steel shell and internal I-beam construction, the Duplex is designed to work dependably for years in the harshest of touring environments. A full complement of connectors make the Duplex a God-send when faced with the never-ending challenges of professional touring, broadcast and AV integration.
