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.
Network tab (map of
the groups only) and
Control tab. Used
diminutive: “A”.

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.
Network tab (map of
the groups only) and
Control tab. Used
diminutive: “V”.

Mains 1 Voltage Mains voltage (in V) measured from the
MAINS 1 plug at the back of the NXAMP in
case of NXAMP4x4 (unused for NXAMP4x1).

Mains 2 Voltage Mains voltage (in V) measured from the
MAINS 2 plug at the back of the NXAMP in
case of NXAMP4x4, MAINS plug in case of
NXAMP4x1.

Power Supply
Voltage (per ch.)
Output voltage (in V) of the power supply
feeding power amplifier for a channel.

Power Amp
Temperature (per
ch.)
Temperature (in °C) of the amplifier for a
channel.

Low and High Load
Alert (per ch.)
Should be used in conjunction with the load
monitoring function of the NXAMP (see user
manual for details). 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.
 
Amplifier limiting
output
The amplifier has to reduce its output level
for protection (if too hot). Output level is
reduced by 3dB if one of the power
amplifier’s heat sink reaches 70°C, then 3
more dB above 80°C.
 
Amplifier muting
output
The amplifier has to mute its output for
protection (if extremely hot –more than
90°C on the heat sink– or if a problem
arises on a channel, e.g. DC output
detected, low power supply’s output level,…
see user manual for more detail).
 
Power Supply
Overtemperature
(per ch.)
Abnormal temperature has been detected
by the temperature sensor on the heat sink
of the power supply.
 
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 230V mode, and 60V
to 150V for the “U” version or the “W”
version started in 120V mode).
 
Power Supply
On/Off Status (per
ch.)
Equals 1 once the power supply has
finished its soft starting and is ready, else
equals 0.

Power Supply
Starting Status
(per ch.)
Equals 1 when the power supply is starting
up (soft starting).

Power Supply
Output Voltage
Error (per ch.)
The output of the power supply is out of the
limits (10V to 250V DC).
