Ashly Power Amplifiers FET-200 - Manual (Page 9)

METERS
The meters on the front panel respond to the peak output voltage of the
amplifier as measured at the speaker terminals. A ten segment, three color
LED display covers a twenty-seven decibel range.
If all of the LED’s on one channel light up and stay on with only a small
input signal, a blown speaker fuse or faulty speaker wiring is indicated.
THERMAL STATUS INDICATOR
In the event that the amplifier overneats, it will automatically shut down and
the green THERMAL STATUS LED will turn off. The fan will continue to run, and.
vdien the heat sink temperature returns to normal the green THERMAL STATUS LED
will come back on and the amplifier will turn itself back on.
It is extremely unlikely that any combination of musical program material and
load conditions will activate the thermal shutoff mechanism in normal use.
Should overheating occur, check to be sure that the air flow in front of and
behind the amplifier has not been blocked.
Note that there is a very generous safety margin between the temperature
required to activate the thermal cutouts and temperatures which could damage
components in the amplifier.
