Alto MC250.4, Руководство пользователя

Страница: 11 / 15

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
the following instructions describe the common ways to install your MC250.4 power amplifier into a sound application
system:
First, turn off power switch before connection.
Refer to chapter 5 for speaker connection
MC250.4 power amplifier may be operated in one of the three modes, please slide the mode selector for the
Specific operating mode
6.2 caution for speak connection
The output capacity of MC 250.4 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 MC250.4 power
amplifier, you can protect your speakers by connecting a fuse serially between the speaker and the amplifier
as shown below.
