NXAMPMK2 USER MANUAL PAGE 43 / 80
INPUT MONITORING
The NXAMPmk2 Input Monitoring is an audio input-based pilot tone detection and monitoring function,
measuring in real-time the pilot tone presence on the amplifier input channel. This allows to report (through
its GPIO port or network) whether the audio sources are correctly connected to the amplifier and ready to
use. This function can be enabled and configured on every channel.
This is particularly useful for safety installations where the status of audio chain should always be known,
and any fault should be reported.
This menu allows setting up all the NXAMPmk2 Input Monitoring parameters per channel. Basically, this
monitoring function measures the pilot tone presence on the amplifier channel input at one frequency point
and can report an input pilot tone detection) if the pilot tone is not detected.
All settings on this page are channel dependent. Select the channel first using the top four buttons named
from Ch.1 to Ch.4.
Pressing the Help button reminds you on how the input monitoring works, including a schematic of where
the input signal is monitored for each channel (post input patch):
