A necessity for your audio toolkit
The ProAV1 provides you with the ability to connect almost any audio source to a PA system, while automatically summing stereo sources to mono to preserve channels and simplify the audio setup. Inputs are available via 1/4", RCA, 3.5mm stereo, and line-level XLR connections, giving you the ability to easily connect to smartphones, tablets, laptops, CD players, or even a +4dB line level output from a console or recording interface. Transformer isolation helps eliminate noise while maintaining a linear frequency response, and a mono balanced XLR output allows you to feed a recording interface or a PA system.
