The Radial Engineering ProAV2 is a passive direct box specifically developed with the audi-video integrator in mind. The ProAV2 has full two-channel stereo functionality. Custom wound transformers are employed that are able to withstand exceptionally hot levels while maintaining linearity from 20Hz to 18.5kHz. The ProAV2 is ideal for events that interlace audio with video where music sources can include iPods, CD players and video decks. The ProAV2 stereo version trades some of the connectivity features for it's full dual-channel stereo operation. The ProAV2 will be welcome additions to the AV technician's tool box.


  • Pro 'Swiss Army knife' direct box for multi-media
  • Easy to use passive ultra-quiet design
  • Elimiates ground loops causing hum and buzz
  • Handle huge transients without distortion
