Resistor terminal

An amplifier is needed if more than 32 decoders are connected , signal amplification should not be more than 5 times continuously.

or use overlong signal line

If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120Ω terminal resistor at the end of each line.

LT-904 is equipped with 2 types DMX terminals for users’ selection. The following diagram takes 3-pin XLR as an example, same connecting method for RJ45.

* Installation attention : please reserve enough ventilation distance between decoders (>20mm),

be sure not to block the vent, or will affect lifetime of decoder for .poor heat dissipation
