For some reason, that headline sounds just wrong, but whatever. Here's the Bird Electoron DJ-4, "the passive type micro mixer of power source unnecessary." In other words: yes, it's from Japan and yes, it's a very simple passive mixer with two mini-stereo inputs and one output. The seller for me is the two big analog knobs: VOLUME and VOLUME. For just $70 you will be able to connect your two MP3 players and touch your own two big knobs until your audience's ears bleed. Or they throw you into the river inside a sack full of rocks after you play the same Black Eyed Peas track for the 28th time.
