RADIAL ProAV1 Multimedia DI
The Radial ProAV1 is a single channel passive direct box designed specifically for the audio
video professional where ‘Swiss Army knife’ connectivity is required to meet on-the-fly
demands of AV rentals and installations.
Perfect for Noise-Free Laptop to PA system connections!
Featuring a 3.5mm and RCA stereo inputs, connecting a laptop's stereo signal to the DI is simple. The ProAv1 will then 'sum' the stereo signal (Left, Right) into mono, meaning you lose none of the original signal, just without the 'stereo panning'. A quality Radial transformer and ground lift means that distortion and ground loops can be avoided.
Durable Construction and Design
A high performance custom-wound transformer is employed that converts the impedance and balances the line while providing exceptional common-mode rejection. The transformer eliminates noise associated with ground loops. To further reduce susceptibility to noise, the transformer is encapsulated in a nickel metal can, thus preventing RF and electromagnetic induction. The ProAV1 is constructed with 14 gauge steel for durability, while it’s book-end enclosure is designed to protect the switches and connectors from damage.
Professional and Consumer AV Connectivity
Input connectivity includes stereo RCA, 1/4" and 3.5mm (1/8") for high-impedance instrument and -10dB consumer line-level devices. All inputs may be used as thru-puts and are auto merged to mono to reduce cable infrastructure and audio channel requirements. A +4dB XLR input is also provided to interface professional balanced line-level signals. The output is standard 600 Ohm mic-level for direct interconnect to mixing console mic inputs. These features make the ProAV1 an ideal interface for portable computers, CD players, iPod's and other sound sources that must interface to PA systems alongside microphone lines.

The Radial ProAV1 is a passive direct box 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, both units are 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, iPod's, 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.
Custom wound Radial 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 ProAV1 a 'must have' problem solver for the audio-visual technician's tool kit.
