The Radial ProAV1 is a single-channel, passive direct box specifically developed for audio-video integration. Multiple input formats and mono-stero merge function make it ideal for almost any A/V use.
The ProAV1 is essential for sending the signal from your iPhone, iPad, computer or other iOS device to a PA or recording mixer. Here's why: The signal from your 3.5mm (1/8") consumer-device output is simply too hot for most recording or audio mixers. By converting the output impedance, you get much better sound: higher highs, deeper lows and noticeably cleaner, better response.
The ProAV1's custom-wound transformers withstand exceptionally hot levels while maintaining warm and natural sound—making the AV1 particularly adept at handling high-output, harsh-sounding digital sources.
