Radial ProAV1 Passive Direct Box

The Radial ProAV1 Passive Direct Box is specifically developed with the audio-video integrator in mind, where ‘Swiss Army knife’ connectivity is required to meet on-the-fly demands of AV rentals and installations. Featuring a variety of stereo inputs that are summed mono via a resistive mixer, the ProAV1 greatly simplifies signal management.

The Radial ProAV1 Passive Direct Box comes 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 Radial ProAV1 Passive Direct Box eliminates the need for various adaptors,

The Radial 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.

Custom wound Eclipse ET-DB2 transformers are able to withstand exceptionally hot signal levels while maintaining linearity from 20Hz to 20kHz. 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 Radial ProAV1 'must have' problem solver for the audio-visual technician's tool kit.

Radial ProAV1 Passive Direct Box Applications
