The ProAV2 is a stereo passive direct box perfect for anyone needing to send a variety of signals from stereo consumer products to a professional mixer and loudspeaker system.Inputs are available via 1/4", RCA, and 3.5mm stereo connections, meaning you can connect virtually any consumer device to your PA system without shuffling around for the right adapters. Signals are then sent through to two XLR outputs, allowing for stereo mixing and panning at your soundboard. In addition, when sending in signals through the 1/4" inputs, the RCA jacks then act as thruputs. This means you can use this as a stage direct box, sending your guitars or stereo keyboards to the board while using the RCA thrus to send the signal back to your amplifier.Like any good direct box, the ProAV2 offers transformer isolation to help eliminate noise and keep a linear frequency response, a -15 dB pad switch to manage how much signal you're sending through, and a ground lift to nix out buzz from ground loops. All of this fits in Radial's rugged bookend-style chassis.The Radial ProAV2 is a must-have for anyone needing to send their consumer-level signals to a professional sound system with no hassle or noise.
