Used but great condition BMD Smart Videohub 12x12. I've installed the Nebtek quiet on-set fan mod, which greatly reduces the noise the stock fans generated. Perfect if you're on a stage and need to have low-noise from your cart. The stock fans are very loud.
The mod also allows you to power the device via DC! Has a 4-Pin male XLR out, and an adapter to AC if you need to power it via AC.
The mod is completely non-destructive to the device. You can remove the mod if you want in under 5 minutes and re-install the factory fans (included).
Works great, no issues. I upgraded to a 20x20.
Brand new sells for $1855 (including the mod)
