Murdered Out Baggers LLC.
I Customize Harley Davidson motorcycles for a living and a lot of them want high end stereo systems on them. So I use it with a few SMD tools and an Audio Control DM-RTA to adjust the DSP on the system for the best overall sound you could want. I bought 3 different ones. The Tone tester and the pink noise generator as well as the sweep tone generator. Love them all. They don’t time out or stop for any reason.
