This is a 4-way DMX booster with a 3-pin and 5-pin XLR input jack. This unit takes the incoming DMX 
signal and splits the signal into four separate output channels. Each output channel and the input channel 
are completely electronically isolated from each other, all four output channels have independent output 
drivers to boost the DMX signal. In addition, a Link out/Terminate selector is used for secure linking when 
you intend to terminate DMX signal.

Before plugging your unit in, be sure the source voltage in your area matches the required voltage for your 
B-4 Booster power supply. The B-4 Booster is only available in a 230v version. Due to variations in line 
voltage from venue to venue, be sure to plug your power supply into a wall outlet with matching power before 
attempting to operate.
