Radial ProAV1 | Single Channel Passive Direct Injection Box

The Radial ProAV1 is a versatile, single-channel passive direct injection (DI) box crafted specifically with the audio-video integrator in mind. Designed for multi-media applications, the ProAV1 excels in simplifying signal management through its array of connectivity options and transformer isolation capabilities. This robust DI box features a variety of stereo inputs that are summed mono through a resistive mixer, making it an indispensable tool for professional audio environments. The Radial ProAV1 ensures that whether you are working with musical instruments, CD players, iPods, video decks, or computers, your audio signal remains clear and hum-free.

The ProAV1 is engineered to accommodate high signal levels without compromising on audio quality, thanks to its custom-wound Eclipse ET-DB2 transformers. These transformers are able to maintain a smooth and natural Bessel curve, which is particularly valuable for digital sources that can often produce harsh sounds. The transformer isolation further enhances audio quality by eliminating ground loops and DC offset problems, providing an ultra-quiet performance.

With its rugged design and superior functionality, the Radial ProAV1 is a must-have solution for audio-visual technicians who require a reliable and easy-to-use DI box. This unit supports a wide range of input options including 1/4" inputs for instruments, RCA and 3.5mm connectors for consumer audio sources, and a female XLR input for professional audio equipment. Additionally, these inputs can serve as thru-puts, allowing for flexible patching in various audio setups.
