Hi, up for sale is my ATI Studio Metering System VU400. In used cosmetic condition. I have quickly tested the meter by putting sound through it in both channels and it seems to work, it might need calibration (I see one meter keeps one led on, even with no signal), and I don't know if it is fully functional. There's not a lot of information on the internet, but I thing this are pretty good audio meters.
Sold as shown in pictures.
