As to the speaker cable, if you use a long one, use as thick a cable as possible to prevent deterioration of the
damping factor or power loss inside the cable.
Use the following formula to determine the fuse capacity according to the speaker's input capacity.
Po=I R I= Po/R
2
Po[W] : Speaker's continuous input capacity (noise or RMS)
R[ ] : Speaker's nominal impedance
I[A] : Required fuse capacity
6.CAUTION FOR APPLICATION
6.1 General Application instruction
