No Function:
The connection cable is not connected correctly( = terminal CABLE/GND /R
EM).Ensure that all connections and mechanic contact and that the jacket
has been removed. The fuse is defective-pay attention to the correct value of
a new fuse.
No Sound:
Speaker cable or speaker plug are not connected correctly.
No Sound /Red L ED Prote ction Shines:
The plus and minus wires of the speaker cable have contact, thus eliminate
the short circuit. If you use a 2 Ohm s peaker in stereo mode, a 4 Ohm speaker
in.bridge mode or tri-mode and the set is overloaded, then turn the gain
control to "min" until the operation is free of trouble.
