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.
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.
