INSTRUCTIONS FOR USE
ON AND OFF
Before switching on the power supply check that the volume controls of channels 1 to 4 are at their minimum.
Switch on the rest of the audio system and finally switch on the amplifier and adjust the volume controls.
To switch off the audio system adjust the amplifier’s volume to the minimum and switch it off.Finally switch
off the rest of the audio system.
PROTECTION
The amplifier has 4 types of protection: overload, overcurrent, surge and temperature.
When protection is activated, an LED indicator lights up in the front panel and cuts off the audio output. In
this case, check what has caused the activation of the protection, leave it to recover for a few moments and
then switch it back on.
RESETTABLE FUSE
The power supply source is manufactured with advanced components which absorb current peaks and
eliminate fluctuations caused by switching the amplifier on. Furthermore, the amplifier is equipped with a 10
A BREAKER resettable fuse located in the rear panel.
If the fuse is cut off, due to a surge or excessive consumption, switch the power amp off, check what has
caused the fuse to be cut off, let it recover for a few moments and reset the fuse BREAKER by pressing it.
