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-916 is equipped with 3 kinds of DMX terminals for users’
selection. The following diagram takes 3-pin XLR as an
example, same connecting method for the rest two: RJ45
& green terminal (with amplifier function).
