The successor to the original “Swiss Army knife” of DI boxes, the Radial ProAV2 is a passive DI box designed exclusively for live sound applications that interlace audio and video. It features a plethora of stereo inputs that drastically reduce the amount of cables required. These inputs pass through a resistive mixer before being summed to a mono signal and routed to a single output. Inputs include 1/4” instrument ins, RCA,1/8” connections, and +4dB stereo XLR outs. Even better, each of the unit’s front panel inputs can be used as thru-puts, affording multiple patch points. There’s also a -15dB pad for conditioning unruly signals while the ground lift negates buzzes and hums imparted by ground loops.
