A "Swiss Army Knife" for audio-visual systems, the ProAV1 is a single channel passive direct box with built-in stereo to mono merge function for easy connectivity. Input/output options include 1/4" jacks for instruments, 3.5mm (1/8") and RCA connectors for -10dB consumer products, an XLR input for professional +4dB balanced line-level sources and custom-wound transfomer with nu-metal shield. The ProAV1 is a must have for the AV intregrator. ️WARNING: Cancer and Reproductive Harm - www. P65Warnin
