Manufacturer's Description from Radial

The ProD2 from Radial Engineering is a high-quality, stereo, (2-channel) ultracompact passive direct box, designed for electronic keyboards, guitars, bass, and drum machines.

The unit features dual custom-made transformers that are able to handle high levels without saturation and has an exceptionally linear frequency response from 20 Hz to 20 kHz, making it ideal for electronic musical instruments and audio equipment. Also featured on each channel are -15 dB pads for high-output sources and ground-lift switches to troubleshoot noise from ground loops.

A 14-gauge welded I-beam inner chassis and outer shell greatly reduce the possibility of torque stresses being applied to the PC board. A full-bottom, no-slip rubber pad works double-duty by providing protection from electrical shock and making sure the ProD2 stays put.

  • Great sounding, stereo, rugged passive DI for electronic keyboards and drum machines
  • High-performance custom-wound transformers eliminates noise
  • Very-low harmonic and phase distortion
  • -15 dB pads for wide range of input levels and ground-lift switches eliminate ground loop hum
  • Ideal for live sound and studio
  • Passive design requires no external power

About Manufacturer

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.
