LOG and ALERT PARAMETERS
PAGE 64 / 70 NXAMPMK2 USER MANUAL
Output voltage (per
ch.)
Peak voltage (in dBFS, 0dBFS being the
clip level of the voltage sense converter)
of a channel (accuracy of ±3dB, and
maximum rate of 25Hz). A non-null value
informs you a signal is being sent to the
output.
-60, 0 dBFS
✓
Output current (per
ch.)
Peak current (in dBFS, 0dBFS being the
clip level of the current sense converter)
of a channel (accuracy of ±3dB, and
maximum rate of 25Hz). A non-null value
informs you there is a load on the
channel.
-60, 0 dBFS
✓
Sense (per ch.)
A certain level of current is detected on
the output (a cabinet is connected, and
some sufficient signal is flowing to it).
0, 1
✓
Protection (per ch.)
Speaker protection (displacement or
thermal)
0, 1
✓ ✓
Peak Limiter (per
ch.) The peak limiter is working to protect the
amplifier for the channel.
0, 1
✓ ✓
Mute (per ch.) Mute status of a channel. 0, 1
✓
Speaker
Temperature (per
ch.)
Voice coils temperature (in dB, 0 dB being
the maximum temperature the speakers
can safely reach under the current
preset).
-60, 0 dB
✓
Speaker
Displacement (per
ch.)
Membrane displacement (in dB, 0 dB
being the maximum displacement the
speakers can safely reach under the
current preset).
-60, 0 dB
✓
Speaker Protection
(per ch.)
Reduction of the output levels currently
applied by the NXAMP (in dB, 0 dB being
no protection). It is the maximum of all
protections (displacement, thermal, peak
limiter, etc. see System Headroom for
more detail).
0, 60 dB
✓
Low and High Load
Alert (per ch.)
Should be used in conjunction with the
load monitoring function of the NXAMP
(see Load Monitoring). This function
allows sending a high frequency pilot tone
into the NXAMP and thus monitoring the
impedance of the load. If the measured
impedance for a channel goes out of the
user’s predefined limits, or if the NXAMP
cannot measure the output impedance
(no pilot tone, channel muted, and so on)
these alerts are raised.

Power Supply
Overtemperature
(per ch.)
Abnormal temperature has been detected
by the temperature sensor on the heat
sink of the power supply.
0, 1
✓
Mains err
— Power
Supply Mains Error
(per ch.)
The mains voltage is out of the limits
(150V to 288V for the NXAMP “C” version
or the “W” version started in 2 0V mode,
and 60V to 150V for the “U” version or the
“W” version started in 120V mode).
0, 1
✓
PS volt err
— Power
Supply Output
Voltage Error (per
ch.) The output of the power supply is out of
the limits (10V to 250V DC).
