SAFETY (red LED)
It indicates that the amplifier protection
circuits are on. In order for the amplifier to
work again, you need to switch the system
off and then on after 10 seconds at least.
We recommend to check all connections
before switching the amplifier on again.
If LED stays on, please contact Audison
