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.
