Avatar ampliﬁers are high-quality and technically perfect products. The problems often arise due to improper

operation, faulty connection of components or lack of power supply of the on-board network.

1) The ampliﬁer does not turn on.

Problem solution: Check all the contacts and the presence of the ampliﬁer 12 V at the terminals. Check whether the

control input of the ampliﬁer "Remote in" receives the positive potential of 12 V.

2) Power turns on, but goes into protection (security indicator lights up)

Problem solution: Check if there is a short circuit (fault) on the ampliﬁer output which is connected to the speakers or

subwoofers. Make sure that commutation of the coils of the subwoofer is correct. The rated resistance of the coils should

not be lower than the permissible rated load impedance of the ampliﬁer. Check the supply voltage of the ampliﬁer. It

must be within the range of 12-15 V for 12 V versions.

3) The ampliﬁer turns on but at a high volume it goes to protection. Problem solution: The ampliﬁer may lack power.

Make sure that the rated current of the generator and the battery capacity is enough to provide the ampliﬁer with the

increased consumption.

Check the ampliﬁer for overheating. Check the load resistance.

4) The ampliﬁer is turned on, but there is no sound from the speakers or subwoofer.

Problem solution: Check the connection of the ampliﬁer, the integrity of the interconnecting cable, HU, the speaker or

the subwoofer.
