What to expect if your amplifier goes into the protect mode
Your 1350 amplifier has a very sophisticated 1 cycle monitoring system for the power
supply and amplifier. If the system detects a short circuit or a dangerous condition such
as, over temperature, excessive amounts of clipping, excessive current usage, or
improper power configuration conditions the amplifier may go into the protect mode for
safety.
The Red Protect light will come on to alert you that the unit is in the protect mode.
Determine what is causing the unit to go into protect mode. After you resolve that
problem, you will need to shut off and then restart your amplifier.
Whenever the
amplifier goes into the protection mode it will be necessary to shutdown and then restart
the amplifier to clear the safety function lockout and restore the unit to normal operating
