Radial Engineering's ProAV2 is a passive direct box specifically developed with the audi-video integrator in mind.  The ProAV2 has full dual-channel stereo functionality.

To eliminate the need for various adaptor, a 'Swiss Army' array of connections are provided. including 1/4" for instruments, RCA and 1/8" connectors for consumer electronics and computers and a +4dB XLR input(s) for professional systems. Front panel connectors can also be used as thru-puts to allow multiple patch points.

Custom wound transformers are employed that are able to withstand exceptionally hot levels while maintaining linearity from 20Hz to 18.5kHz. The resulting smooth Bessel curve is warm and natural, making the AV2 particularly adept at handling digital sources that can sound harsh. Transformer isolation adds the benefit of eliminating ground loops that cause audio hum and buzz and video hum bars or snow.

Radial Engineering ProAV2 Key Features:

  • 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
