m@ NOTE
The unit is provided with the speaker circuit protection fuses at the right and left channels respectively.
The fuse is to prevent the power transistor from destruction, should the speaker terminals be short-circuited.
Accordingly, if the unit fails to function upon completion of the speaker connections, check the speaker
protection fuses first of all for possible blowing.
