The "Swiss Army Knife" of DI Boxes!

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 merged via a resistive mixer to mono, greatly simplifying signal management.
To eliminate the need for various adapters, 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 output(s) for professional systems.

The ProAV1's 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 20Hz to 18.5kHz. Transformer isolation adds the benefit of eliminating ground loops that cause audio hum and buzz and video hum bars or snow. A -15dB pad is provided to tame hot signals and the ground lift eliminates hum and buzz caused by ground loops. If you do live sound for events, the ProAV1 should be in your tool box!

Great Device

Sound is amazing and it definitely took away any hum that I traditionally get.

Excellent product!

Built like a tank. Worked perfectly to get audio out of a cellphone via the headphone jack – at the podium, through the snake, and into the board. Clean and trouble free. Will find a lot more uses for this.

Amazing product

Excellent product to connect remote sound sources to our sound system, specially laptops. The best solution I had found was a combination of a Galaxy RCA combiner and an ART Clean box II with mediocre results, but much better than nothing. But this baby rocks! Even without using the ground lift, all my noise and ground loops problems got automatically eliminated!! Its construction is awesome! Its got a nice selection of inputs including a 1/8" for laptops!! You will not be disappointed.
