IN CASE OF DIFFICULTY

If you encounter a problem, please review the items in the following checklist. This guide will help you isolate the problem if the unit is at fault. Otherwise, make sure the rest of your system is properly connected or consult your authorized Alpine dealer.

Volume is low.

Input level from the head unit with which the amplifier is being used is low.

Increase the volume on the head unit.

Indication

Cause and Solution

 

 

 

• The protection circuit is

 

 

 

activated due to high

 

 

 

temperature. The amplifier

 

 

 

output becomes disabled.

 

HOT

 

• The indicator will disappear

 

 

when the temperature returns

 

 

 

to within operation range.

 

 

 

 

 

 

 

• The amplifier has been

 

 

 

shutdown due to excessive

 

 

 

heat.

 

 

 

The amplifier is automatically

 

 

 

reset.

 

 

 

• The indicator will disappear
