Deaf Bonce ampliﬁers of Machete series are high-quality and technically perfect products. The problems often arise due to

improper use, 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 9-15 V at the ampliﬁer terminals. Check whether the control input

of the ampliﬁer "REM" 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 voice coils of the subwoofer is correct. The rated impedance of the voice 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 9-15 V for 15V versions of ampliﬁers.

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 alternator and the battery capacity is enough to power this ampliﬁer.

Check the ampliﬁer for overheating. Check the load impedance.

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.
