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.
2
Po=I R I=√Po/R
Po[W] : Speaker's continuous input capacity (noise or RMS)
R[Ω] : Speaker's nominal impedance
I[A] : Required fuse capacity
6.2 Caution for Speaker Connection
The output capacity of out MACRO 830/1400/2400 Professional Stereo Amplifier is very high, be sure to use a speaker
system that has sufficient input capacity. If the input capacity of your speaker system is lower than the rated output of
the MACRO 830/1400/2400 Professional Stereo Amplifier, you can protect your speakers by connecting a fuse serially
between the speaker and the amplifier as shown below.
