Possible Solutions
55STAT
: Output
Thermal Limiting
•
The specified
amplifier channel has
overheated and is
muting the affected
channel.
•
The channel is driving
too low of a speaker load
impedance.
•
The channel is being
fed a heavily clipped or
distorted signal.
•
The amplifier operating
environment exceeds the
recommended operating
temperature.
•
Make sure the correct
speaker load is connected.
•
Check that the speakers are
tapped appropriately.
•
Recheck the amplifier gain
structure.
•
Verify that the amplifier
ambient environment
does not exceed the
recommended operating
temperature (see 53STAT).
57STAT
:
Overload
•
The current/power
limiter has been
triggered.
•
A short on the affected
output channel has
been detected.
•
Too much current is
being drawn due to
overdriving the output.
•
An improper speaker
load has been attached
(for example, attaching a
low impedance speaker
to a high impedance
output).
•
The output has been
shorted.
•
Recheck the amplifier gain
structure.
•
For low-impedance loads:
Verify that total impedance
at the amplifier is ≥ 4 ohms.
•
For 70V/100V speaker
loads: Recheck speaker
taps.
•
Check for shorts at the
output and throughout the
speaker chain.
58STAT
: Open
Circuit
•
The affected channel
has detected an open
circuit.
•
The connection to the
speaker chain has been
broken.
•
An improper speaker
load has been attached
(for example, attaching a
high impedance speaker
to a low impedance
output).
•
No speaker load is
attached.
•
Check for an open circuit at
the output and throughout
the speaker chain.
•
Recheck speaker taps.
60STAT
: Loss
of AC
•
If a “2” is reported:
Loss of AC is
detected.
•
If a “1” is reported:
A momentary loss of
AC power has been
detected in the past.
•
There is/has been a
disruption in power.
•
Check the system power
distribution.
