Radial Pro AV2 Direct Box

The Radial ProAV2 is a passive direct box specifically developed with the audi-video integrator in mind with full two-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 able to withstand exceptionally hot signal levels while maintaining linearity from 20Hz to 18.5kHz. The resulting smooth Bessel curve is warm and natural, making them particularly adept at handling digital sources that can sound harsh. Transformer isolation further benefits by eliminating hum and buzz caused by ground loops or DC offset problems

These features combine to make the ProAV2 a 'must have' problem solver for the audio-visual technician's tool kit.
