Inputs and Monitor output
On top of the ML1, three connectors as well as the internal microphone
are located:
• The XLR and RCA inputs allow to feed a signal to the ML1.
• A 3.5 mm (1/8“) jack monitor output allows the connection of a
headphone. Thus, the user may hear the input signal.
• The internal microphone provides the possibility to test the polarity
of an acoustical signal if the NTi Audio’s Minirator polarity check
signal is played back. This especially serves to check the polarity
of loudspeakers.

NOTE Never connect the XLR- and the RCA input at the same
time!
Music detection
Automatic gain control is applied to the input signal before being
analyzed and made audible from the monitor jack. In this mode, the
monitor signal behaves similar like a compressor output, whereby the
user hears an almost constant sound pressure level. For input levels
lower -20 dBu the gain is set to +20 dB.
NOTE The automatic music detection is only available in
the measurement functions LEVEL RMS, LEVEL REL,
THD+N, POLARITY, BALANCE, SWEEP and SCOPE.
