Radial PROD2 | Two Channel Passive Direct Injection Box

The Radial PROD2 Two Channel Passive Direct Injection Box is the ultimate solution for musicians and audio engineers who demand uncompromising performance. Designed to seamlessly interface stereo keyboards with professional audio systems, this direct box offers unparalleled clarity, warmth, and reliability. Whether you are on stage or in the studio, the PROD2 ensures that your sound is accurately and beautifully reproduced, free from unwanted noise and distortion.

At the heart of the PROD2 are two high-performance Eclipse ET-DB2 transformers. These components deliver a broad frequency response from 20Hz to 20kHz with minimal distortion, even at high input levels. Unlike active direct boxes that can overload and distort, the passive design of the PROD2 naturally smooths out the signal, providing a subtle limiting effect that enhances the tonal quality of digital pianos, samplers, and drum machines. This makes the PROD2 an indispensable tool for musicians who require consistent, high-quality audio output.

Built with durability in mind, the PROD2 features a robust 14-gauge steel chassis and a unique I-beam internal structure that protects sensitive components from physical stress. The innovative book-end design shields connectors and switches, while a full-bottom no-slip pad ensures mechanical isolation and electrical insulation. This combination of design and construction means the PROD2 is more than capable of withstanding the demands of professional touring and long-term use.
