Radial ProD2 2-Channel Passive Stereo Direct Box - Compact Keyboard Integration
The Radial ProD2 is a high-quality, ultra-compact stereo passive direct box designed specifically for interfacing keyboards, DJ equipment, and consumer hi-fi systems with professional audio rigs. Essentially two ProDI units in one enclosure, it features custom-wound Radial transformers for exceptional linearity (20 Hz–18 kHz) and subtle limiting to tame excessive dynamics from digital sources. Battery-free and rugged, the ProD2 eliminates hum and ground loops, delivering warm, natural sound for live performance and studio use, all in a durable steel chassis.
Custom Radial Transformers
The ProD2's high-performance transformers provide pristine signal transfer, acting as subtle limiters for digital pianos and samplers while rejecting hum from ground loops. Its passive design requires no power, making it reliable for touring, and the compact layout simplifies stereo keyboard connections with thru-puts for stage amps.
