Status Commands

NOTE: Status flags automatically reset when the amplifier is power cycled.
Status Possible Triggers
53STAT:
The amplifier has
Over Temp
exceeded the
recommended operating
temperature.
See specifications.
54STAT:
A DC signal has been
DC Protection
detected on an amplifier
channel.
55STAT:
The specified amplifier
Output Thermal
channel has overheated
limiting
and is muting the affected
channel.
57STAT:
The current/power limiter
Overload
has been triggered.
A short on the affected
output channel has been
detected.
Possible Causes
The ambient environment
exceeds the recommended
operating temperature.
Hardware failure.
The channel is driving
too low of a speaker load
impedance.
The channel is being fed
a heavily clipped/distorted
signal.
The amplifier's operating
environment exceeds the
recommended operating
temperature.
Too much current is being
drawn due to overdriving
the output.
An improper speaker load
has been attached (i.e.
Attaching a low impedance
speaker to a high
impedance output).
The output has been
shorted.

Possible Solutions
Verify that the placement of
the amplifier allows for suitable
ventilation and airflow.
Avoid placing equipment on top or
below the amplifier.
Verify that the operating
temperature is within the specified
range.
Disconnect power then reconnect
power to the unit to determine if the
unit immediately goes into standby
upon power up.
The amplifier may need to be
serviced.
Make sure the correct speaker load
is connected.
Check that speakers are tapped
appropriately.
Recheck the amplifier's gain
structure.
Verify that the amplifier's ambient
environment does not exceed
the recommended operating
temperature
(See 53STAT).
Recheck the amplifier's 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.
