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.

Use the following formula to determine the fuse capacity according to the speaker's input capacity.

Po=I2 R I=Po/R

Po[W] : Speaker's continuous input capacity (noise or RMS)

R[ ] : Speaker's nominal impedance

I[A] : Required fuse capacity

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.
