The Radial ProAV1 is passive direct boxes specifically developed with the audio-video integrator in mind. The ProAV1 features a variety of stereo inputs that are summed mono via a resistive mixer, greatly simplifying signal management. 

To eliminate the need for various adaptors, the unit is equipped with a 'Swiss Army' array of connectivity options including 1/4" inputs for instruments, RCA and 3.5mm (1/8") connectors for CD players, iPods, video decks and computers. The ProAV1 also features a female XLR input for interfacing equipment with +4dB professional signal levels. The front panel connectors can also be used as thru-puts to allow multiple patch points.

These features combine to make the ProAV1 'must have' problem solvers for the audio-visual technician's tool kit.
