This is the strip of DMX. This box can SAVE the cable and connect more devices.

Pros:
-4 Amplified outputs.
-1 Direct output.
A button-termination, the case is the last link but amplified outputs are still functioning.
-2 Lights, red and green in between and outputs indicating the presence of DMX.
Mtallique-box robust.
It very clear connection Schematic on the case.
-Price.
-The size and light weight.

Cons:
-May be a lack of protection for connectors.

Benefits on where I put a number of machines, this box saves me time m'vitant wiring in the tedious formatting series of all my appliances, makes me put less cables and allows me to group my cars: face, cons, power blocks ... In addition, LEDs can be inspected if the DMX signal travels well. Example: if no DMX enters it, nothing lights.

For now I do not need another device, but if necessary I think I could one without hesitating.
