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-905 is equipped with 2 types DMX

terminals for users’ selection. The following
