Boost 4C Dimmer DMX 4 Voies

Chinese-made device sold under various brands (Mac Mah, Tutelo Starway, Kool Light, American DJ etc..) I use two for a few months on tour. The operation is correct and has no major defects. The program addresses is very simple and the machine performed its function perfectly in DMX mode 4 channels with a DMX Starway.

Such incidents should not happen on professional equipment, but here was a cheap device cheap and made in China, anything can happen. It is therefore recommended to have a block in advance if something goes wrong (considering the price, it's possible). on the other hand, it obviously takes a little more room ...
