The amplifier is in “fault” mode. A Fault status
can be triggered when one of the amplifier’s
protection circuits is activated. First disconnect
your speakers from the affected channel (s) one

determine where the short is occurring. If no
short can be found, turn off the amp and allow
the amp to cool. If indicators do not return to
normal after restarting your amp, check the fuse
and replace if necessary, or return amp to
Crown or an authorized Crown Service Center
