The Radial Pro AV1 is a passive direct box specifically developed with the audio-video integrator in mind. The Radial ProAV1 features a variety of stereo inputs that are merged via a resistive mixer to mono, greatly simplifying signal management.

To eliminate the need for various adaptors, a 'Swiss Army' array of connections are provided with the Radial ProAV1, 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 20 Hz to 18.5 kHz. The resulting smooth Bessel curve is warm and natural, making the Radial ProAV1 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.

The Radial ProAV1 is ideal for events that interlace audio with video where music sources can include iPods, CD players and video decks. The Radial ProAV1 will be a welcome addition to the AV technician's tool box.

The main features of the Radial Pro AV1 include:

• 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
