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.

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

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.
