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
6.2 Caution for Speaker Connection
The output capacity of MAC 2.2/2.3/2.4 stereo power 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 MAC 2.2/
2.3/2.4 stereo power amplifier, you can protect your speakers by connecting a fuse serially between the speaker and
the amplifier as shown below.
