Stereo Passive Multimedia Direct Box
The ProAV2 is a stereo passive direct box designed for audio-video integrators and technicians, with an array of input connector
options to easily interface with a wide range of audio equipment.
Versatile stereo direct box for multimedia applications
Easy to use, ultra-quiet passive design
Transformer isolation eliminates hum and buzz
Handles huge transients without distortion
Connect any device to the PA system
The ProAV2 is an indispensable device for live sound engineers and audio-video technicians alike, with the ability to seamlessly
interface nearly any device with a pro audio system. A 3.5mm stereo input jack and dual 1/4" and RCA connectors ensure that you won't ever be hunting around for adaptor cables, while ultra-quiet performance with transformer isolation helps eliminate hum and
buzz from ground loops. The ProAV2 maintains stereo separation and exhibits linear frequency response from 20Hz to 20kHz, with balanced mic-level XLR outputs that allow you to send signals through a multichannel audio snake on stage or into two channels of
a mixing console.
ProAV2 Specifications
The Radial ProAV2 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.
