Fuse Replacement

CAUTION! The LB-Par™ RGBW utilizes a high-output switch-mode

power supply with an internal fuse. Under normal operating condi-

individuals. Should your LB-Par™ RGBW fuse require replacement,

please contact Blizzard Lighting for instructions, or to return your unit

for service.

applications. Standard microphone cables will “probably” be OK, but

note that they cannot transmit DMX data as reliably over long distanc-

es. In any event, the cable should have the following characteristics:

2-conductor twisted pair plus a shield

Maximum capacitance between conductors – 30 pF/ft.

Maximum capacitance between conductor & shield – 55 pF/ft.

Maximum resistance of 20 ohms / 1000 ft.

Nominal impedance 100 – 140 ohms
