At the heart of the ProD2 are two high performance Eclipse ET-DB2 transformers. They deliver 20Hz to 20kHz performance with less than 1.5dB deviation above 18kHz and can handle high signal levels without distortion. Unlike active circuits, transformers saturate, creating a pleasing tone - perfect for digital pianos, samplers, and drum machines. They also excel at eliminating ground loop hum and buzz.
The ProD2's innovative design includes a 14-gauge steel ultra rigid i-beam skeleton frame, protecting the sensitive PC board. The book-end design safeguards connectors and switches, and the full bottom no-slip pad provides mechanical and electrical isolation, reducing noise.
With its warm sound, legendary build quality, and compact design, the Radial ProD2 has become the most popular stereo direct box on the market.
