Radial Engineering ProAV1 Multi Media DI

When you have a changing cast of consumer audio and line level signals that need to be summed and sent to one mixer channel, the Radial ProAV1 gives you everything you need in one passive direct box!

Inputs are available via 1/4", RCA, 3.5mm stereo, and line-level XLR connections, meaning you can connect virtually any consumer device to your PA system. Stereo signals are summed into one XLR out, giving you more room to work with on your mixer. RCA thruputs are available for consumer-level recording, while a 1/4" thruput allows this to be used like a usual stage DI box between your electric guitar, your amp, and your mixing board.

Like any good direct box, the ProAV1 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.

If you're seeking a versatile multi-media DI box with a mono output, the ProAV1 is a great choice. Order yours today!
