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.

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.
