Passive Multimedia Direct Box

The ProAV1 is a passive direct box with multiple input connector types and a stereo-to-mono merge function designed specifically for AV integrators to reduce channel requirements.

• Versatile direct box for multimedia applications
• Easy to use, ultra-quiet passive design
• Transformer isolation eliminates hum and buzz
• Handles huge transients without distortion

A necessity for your audio toolkit

The ProAV1 provides you with the ability to connect almost any audio source to a PA system, while automatically summing stereo sources to mono to preserve channels and simplify the audio setup. Inputs are available via 1/4", RCA, 3.5mm stereo, and line-level XLR connections, giving you the ability to easily connect to smartphones, tablets, laptops, CD players, or even a +4dB line level output from a console or recording interface. Transformer isolation helps eliminate noise while maintaining a linear frequency response, and a mono balanced XLR output allows you to feed a recording interface or a PA system.

The Radial ProAV1 is a passive direct box designed to handle the extreme dynamics and frequency range that is now common with digital sources. Linear across the audio range, it exhibits low distortion at all frequencies, amazing signal handling and very little phase shift. The result is a clean, natural sounding rendition that is both noise-free and dependable.
